Understanding Spam Filters

Before we explore why your emails are going to spam, it’s important to understand how spam filters work.

Spam filters are software programs that scan incoming emails for unsolicited or dangerous emails and classify them as either spam or legitimate. There are different types of spam filters, but they all have a common goal, to protect users from unwanted and potentially harmful emails.

Spam filters use various criteria to determine whether an email is spam. These criteria may include the following but are not limited to:

  • sender’s reputation
  • email content
  • presence of attachments
  • email’s format
  • recipient’s behavior

If an email meets the spam filter’s criteria, it’s classified as spam and sent to the recipient’s spam folder.

First, let’s start with all the reasons why emails go to spam in the first place. Then, we’ll dive headfirst into some actionable solutions to get your emails back in your subscribers’ inbox where they belong.

Why Are My Emails Going to Spam

Let’s take a detailed look into the 16 reasons why your emails aren’t getting past the spam filters and are going to the spam folder.

1. You Aren’t Targeting the Right Audience

When your emails are inaccurately marked as spam, it could be because you have low engagement rates. One of the tell-tale causes of low engagement rates is having the wrong audience on your email list in the first place.

Every marketer tries to grow their email list as large as possible. And considering the importance of email marketing, they should improve their email list as much as possible.

But rather than simply getting more subscribers, marketers must focus on getting the right subscribers. How can they do that?

By using targeted optin campaigns with OptinMonster:

OptinMonster Home Page 2023

OptinMonster allows you to create optin campaigns that target exactly the audience you’re looking for. Because we offer many different targeting options, you don’t need to cast out a net to get leads blindly.

Instead, you can set up various display settings and triggers to make sure you’re only adding people who fit your buyer persona.

As a result, your engagement rates will rise, and your emails will be sorted to the right place.

2. You Don’t Have Permission to Email Subscribers

The #1 rule of email marketing is to get permission to email first. Never buy a list of email addresses; you risk violating the CAN-SPAM Act and may be subject to penalties of up to $16,000. Oh, and that’s $16,000 per email:

CAN-SPAM Act fines

That means if you’ve been sending an automated email series to people who haven’t permitted you, you’re looking at hundreds of thousands of dollars in fines.

To get permission, you’ll need an optin form on your site that makes it clear that your visitors subscribe to your email list.

Here’s an example of OptinMonster’s sidebar optin form:

OptinMonster sidebar form

When a user fills out this optin form, it’s crystal clear they’ll be joining OptinMonster’s email list.

Another way that marketers harm their email campaigns is by manually adding emails that they get from business cards collected at a conference or from social media.

Let’s be clear on this: Don’t do that.

While you may think they would appreciate your newsletter, sending emails to them violates the CAN-SPAM Act because they did not give you permission.

Instead, you should send those leads personalized emails rather than templated newsletters. Follow up with a separate drip campaign, personal email, or autoresponder series designed just for those leads and give them a chance to optin to your newsletter.

3. Your IP Address Is or Has Been Used for Spam

Even if you never send spam yourself, your emails could get flagged if your IP address was used for spam in the past.

If you send your campaigns through an email marketing service, your email is delivered through their servers. So if even one other customer sends spam, it could also affect your deliverability.

Note, however, that every email marketing service we recommend is vigilant about keeping their reputation intact. They have strict procedures and regulations to prevent this type of thing.

You should be fine if you stick to a reputable ESP (email service provider). And while we can’t verify every ESP in this post, we recommend Constant Contact, Drip, and Brevo (Sendinblue).

We know for a fact that these three providers take email deliverability seriously. Thus, they don’t let spam connect to their server’s IP address.

4. You Have Low Engagement Rates

We already discussed the importance of getting high engagement rates.

Top webmail providers have stated that they look at how many emails are opened and how many are deleted as a factor in spam filtering decisions.

So if you have low open or read rates, your emails are at higher risk of being flagged as spam. You need to do everything you can to increase engagement.

Other than targeting the right audience from the start, you can send your emails at the right time, perfect your subject lines, segment your list, and keep your list fresh by scrubbing it regularly.

5. Your Subscribers Don’t Remember You

The second most common reason emails never reach the inbox is spam complaints.

Every time a subscriber reports an email as spam, the complaint gets recorded by the mailbox provider regardless of whether or not the email was spam.

Once the complaints exceed a certain threshold, all future campaigns skip the inbox and get sent directly to the spam folder.

So why would a subscriber flag your email as spam if it isn’t?

Well, the most likely reason is that they don’t remember you. Even though they gave you permission to email them, they don’t remember doing it, so they think you’re sending them spam.

To prevent this from happening, make sure that the branding in your emails is memorable and matches the branding on your website. This includes any images, colors, typography, and voice. Also, make sure the sender’s name is one they’ll recognize.

It also helps to personalize your email copy to the person you’re sending it to. Here’s an example from an OptinMonster email that includes:

  • Our company’s name where the recipient can see who the sender is
  • Consistent branding with our website
  • Personalized introduction by first name

OptinMonster Email Campaign Why emails go to spam article

Even if subscribers forgot they signed up with OptinMonster, we use these small cues to remind them that we’ve started the relationship.

To make sure they don’t report your as spam, you’ll want to provide an easily accessible Unsubscribe link. That way, they’ll simply opt out of your list instead of reporting you as spam:

Unsubscribe button in OptinMonster emails

Notice how “easily accessible” doesn’t mean you’re encouraging readers to unsubscribe. In the example above from OptinMonster, our call to action (Login to OptinMonster to Get Started) is what grabs attention.

Most email recipients are trained to look for the Unsubscribe button at the bottom of your email. So make sure it’s there, but don’t draw unnecessary attention to it.

Otherwise, you’ll lose subscribers who could have become lifelong customers.

6. You Have Low Mailbox Usage

In their spam filtering algorithms, email service providers look at the ratio of active to inactive email accounts on your list. An inactive email account is an account that hasn’t been used for a long time or is rarely used.

If you’re mailing a campaign to a large number of email addresses that appear to be inactive, that’s a red flag to spam filters.

To prevent this, clean up your email list periodically of any subscribers who haven’t engaged with your campaigns in a while.

You can do that by sending a win-back email to increase engagement. This is a way of giving your audience one last chance to start engaging with their company before you remove them from your email list. Here’s a good example:

Bonobos winback email

Notice the email copy is direct and addresses the situation head-on. Then, the call to action (Yes, Keep ‘Em Coming) encourages users to reengage.

Depending on your email service provider, you can do this automatically. Some providers include a feature to purge any emails from your list that look inactive automatically.

7. Your Subject Line is Misleading

As the CAN-SPAM act states, it’s against the law to intentionally mislead someone with your subject line to induce them to view the email message.

In a survey conducted by Litmus and Fluent, over 50% of participants stated that they’ve felt cheated, tricked, or deceived into opening a promotional email by a false subject line:

litmus & fluent study deceptive subject lines

Here are some examples of misleading subject lines:

  • Did I leave my jacket at your place? This type of subject line can be used as a trick to make it look like they know you.
  • RE: CURRENTLY IN OFFICE is doubly sneaky because it can be mistaken for a reply to your email or a work-related email.
  • Urgent – Update your information. If something says “urgent,” it had better be urgent.
  • Thanks for your order! It’s super poor form to use a transactional subject line if the email isn’t actually transactional.

We know what you’re thinking. “Why would anybody do something like this? These are some super shady tricks.”

You’re so right. But there are also some gray areas you should avoid, too. Here’s one that recently came to our attention by Russel Brunson:

Russel Brunson Bad Subject Line

Now, don’t get us wrong. We’re big fans of Russel and the work he does with ClickFunnels. But this subject line seems conveniently misleading.

It says, bad news… I messed up 🙁 and does a fantastic job building curiosity. The problem?

It’s clearly a sales tactic to create a sense of urgency. The idea is that there’s a big sale that you didn’t hear about because Russell “messed up.”

The reader is left feeling like they got a better deal from the error, and the subject entices them to open the message.

This is a grey area tactic you should avoid. Instead, find a better way of creating strong subject lines that aren’t misleading and are 100% honest. Remember, Russel can afford to take that risk. He’s got millions of dollars in savings and a thriving company that could take a hit.

If you don’t have the same security, playing with email subject lines isn’t worth the risk.

8. Your “From” Information Is Inaccurate

It’s also against the CAN-SPAM ACT to mislead anyone with your “from,” “to,” “reply-to,” and routing information.

For example, if you made your email look like it’s from the President, that would be illegal. It’s an extreme example, but you get the point.

Here’s a real-life example from a popular scam during the COVID-19 pandemic:

COVID19 Scam email

This email is falsely credited to the UK government. Shady practices like this are illegal and should be avoided at all costs.

As a best practice, make sure you include a name in the “from” field that your subscribers are likely to remember and don’t change it too often. It could be the name of an individual, your company name, or a combination of the two.

Like we showed earlier, we send emails with a personal name from our employee and OptinMonster’s brand name:

Angie from OptinMonster accurate from email

Whichever you choose for your brand, shoot for memorability and consistency.

9. You Don’t Include Your Physical Address

You legally must include your physical address. That can be your current street address, a post office box registered with the U.S. Postal Service, or a private mailbox registered with a commercial mail-receiving agency established under Postal Service regulations.

This is usually just above your Unsubscribe button at the bottom of your email campaign:

Add physical address to your email campaigns

You need to add your own address, too. And if you don’t have one because you work from home?

You should definitely get a PO box for business purposes so you don’t have to broadcast your home address.

10. You’re Not Learning From Your Mistakes

We already touched on the importance of adding an Unsubscribe button. But it’s such an essential concept that we need to dive deeper into why it’s crucial.

No matter how valuable you think your email campaigns are, you still need to give your subscribers a way out. If you don’t, you could get spam complaints at best or be slapped with thousands of dollars in fines at worst.

At the bottom of your emails, include an unsubscribe link or a similar opt-out feature.

But, again, you already knew that. So why are we bringing it up now?

Because you should use these unsubscribes as an opportunity to boost your engagement rates in the future.

For example, you can send an “unsubscribe confirmation” email whenever a user opts out of your list. In that email, you can include a survey to figure out why your customer wanted to be removed from your list.

With that information, you can start customizing your email campaigns to prevent similar subscribers from leaving your newsletter. In other words, you’re simply learning more efficiently from your mistakes.

11. You’re Using Spam Trigger Words

Specific words in the subject line or the email’s body trigger spam filters. Some spam trigger words are:

  • Amazing
  • Cancel at any time
  • Check or money order
  • Click here
  • Congratulations
  • Dear friend
  • For only ($)
  • Free or toll-free
  • Great offer
  • Guarantee
  • Increase sales
  • Order now
  • Promise you
  • Risk-free
  • Special promotion
  • This is not spam
  • Winner

Your email provider may have a built-in tool that checks your emails for spam trigger words before sending them.

Keep in mind that the above trigger words are common examples. They may not be specific to your email service provider, however.

So contact your provider directly to see if certain words trigger spam flags. Make a list of words to avoid in your subject line while crafting your email copy.

Some senders hide trigger words in images, as most spam filters do not process images. This tactic can lead to legitimate emails being marked as spam if they follow a similar pattern.

Avoid embedding important information or call-to-action phrases solely within images.

12. Your HTML Emails Don’t Follow Best Practices

If you’re sending text-only emails, you don’t have to worry about this. Text-only emails are the kinds that you typically send to friends and family. Here’s an example of a text-based email:

Text-based email from OptinMonster

However, send HTML emails from your business. That way, you can include some branding elements that make your emails more memorable and helps with engagement.

You can include your brand name at the top:

OptinMonster HTML email

As well as a compelling call to action button at the bottom:

Call to action button HTML email-min

We’ve tested plain text versus branded emails with our email list and found that the branded emails get higher engagement.

It’s definitely a good thing to try with your own list.

However, you need to follow some best practices for sending HTML emails so they don’t get marked as spam:

  • Use a maximum width of 600-800 pixels
  • Keep your HTML code as clean and straightforward as possible
  • Keep your image-to-text ratio low
  • Optimize your images
  • Don’t use obscure fonts
  • Optimize for mobile

To give you an example, here is one of the branded HTML emails that our subscribers love:


See how simple it is? We include our logo at the top for brand recognition, but most email is text.

We also use a simple visual cue, the gray box at the bottom, to highlight the “You are receiving this email because…” area.

This makes the email scannable and reminds subscribers about the benefits of being on our email list.

Alright, so all of this information has been awesome. And now you know why your emails are going to spam instead of to your subscribers’ inboxes as they should.

But let’s turn our attention to seven ways to be proactive and ensure you’re getting higher engagement rates.

13. Your Email Isn’t Properly Authenticated

Lack of proper authentication is a common reason why your marketing emails end up in the spam folder. It also makes it easier for spammers and phishers to use your brand to send deceptive emails, including malware or attempts to fraud.

By implementing smart email authentication standards, you can protect your domain and help email clients distinguish between legitimate emails and spam.

To troubleshoot spam issues, start by ensuring you have set up SPF (Sender Policy Framework) correctly. SPF establishes a list of approved sending IPs for your domain.

Additionally, make sure your emails are signed using DKIM (DomainKeys Identified Mail), a security standard that verifies message integrity.

Lastly, correctly configuring DMARC (Domain-based Message Authentication, Reporting, and Conformance) can prevent phishing attempts and scammers from using your domain, safeguarding your domain reputation and deliverability.

14. Your Subscribers Report Your Email as Spam

If many recipients mark your emails as spam, email providers may filter your emails into the spam folder automatically.

Make sure your email content is relevant and valuable to your subscribers. Always provide an easy-to-find unsubscribe link in your emails so subscribers can opt out instead of marking your emails as spam.

It’s not only a best practice but also a requirement under laws like the CAN-SPAM Act.

15. Attachments

Including attachments in your emails can sometimes trigger spam filters, especially if the attachments are of types commonly used to spread malware (like .exe files).

Be cautious when sending attachments, especially to new subscribers or recipients. Instead of attachments, consider providing links to download files from a trusted source or cloud storage.

16. Inconsistent Sending Volume

If you send emails at irregular volumes, especially if there’s a sudden spike, it can trigger spam filters.

Try to maintain a consistent email-sending frequency. Avoid sudden spikes in email volume, which can be seen as spammy behavior.

How Do I Stop My Emails From Going to Spam

Now that you know the theory behind email deliverability issues and the 16 reasons why inbox identifies your message as spam email, you’re ready to take action. Follow our seven tips to get into your customer’s inbox.

1. Use OptinMonster’s Lead Verification System, TruLead®

A major benefit of using OptinMonster to grow your list is that you can use their original lead verification algorithm, TruLead®.

TruLead® lets you verify your users’ email addresses to make sure that only the highest quality leads are making it to your list.

With their lead verification system, you can block email submissions with:

  • Specific IP addresses
  • Special characters, strings of characters, or patterns
  • Free email accounts (like Gmail, Yahoo, or Hotmail)
  • Role-based emails (help@, info@, support@, and so on)
  • And much more

Verifying your leads with TruLead® saves you tons of money in the long run. That’s because most email service providers charge by the number of contacts on your list.

If half of your list is made from spam submissions, then you’re paying extra money for worthless leads.

Plus, TruLead® helps you earn more money over time. That’s because all your email campaigns will go to the right people, so you can expect to generate higher conversions.

Finally, deliverability rates will increase because more people engage with your email campaigns. Higher open and click-through rates will ensure that your emails go directly to your customers’ primary inbox where they belong.

In the end, OptinMonster is the best tool for making sure that your emails don’t end up in your user’s spam folder.

2. Target the Right Customers From the Start

We’ve already touched on this at the start of the post. But it’s the best way to make sure you don’t get your email campaigns flagged as spam.

You need to use OptinMonster to target the right audience to your email list. Fortunately, we make that ridiculously simple. You have SO many options for targeting your ideal buyer persona, including:

  • Referrer Detection
  • Geo-Location Targeting
  • Page-Level Targeting
  • Cookie Retargeting

And more.

Trigger targets with OptinMonster

But then we also have a list of triggers that help you identify the right subscribers by their interactions with your site.

For example, you could show your optin campaigns after a user has scrolled a certain length of your blog content. Or you could trigger campaigns based on which social media platform your user is coming from.

With OptinMonster, you can make sure that you’re only adding subscribers to your list who are genuinely interested in your content, products, or services. That will reduce the chance of your emails getting marked as spam and increase engagement rates.

3. Use Double Optins From the Start

Another way you can use OptinMonster to prevent your emails from going to spam is to use our double optin feature.

A double optin asks your users to confirm that they would like to be added to your email list after they optin. It looks something like this:

optinmonster double optin

This helps because sometimes you can get false subscribers by spambots. When that happens, you can expect your open rates to plummet.

By using OptinMosnter’s double optin feature, you can make sure the people on your email list are only those who genuinely want more of your content, products, or services.

4. Use WP Mail SMTP

Many of our clients choose not to use an email service provider. Instead, they send their email campaigns directly through WordPress. If you’re in a similar boat, then you need to use WP Mail SMTP:

Over 1,000,000 websites have used WP Mail SMTP to make sure email campaigns go to the right place and are not marked as spam.

It’s also easy to configure. The WP Mail SMTP team will set everything up for you, saving you hours of headaches. Then, you simply need to craft the right email copy and hit send.

Wp Mail SMTP will make sure your emails are appropriately authenticated and sent via trusted 3rd parties. This will guarantee your email campaigns aren’t incorrectly labeled as spam.

5. Tell Subscribers to Whitelist Your Emails

When you send welcome emails to your new subscribers, tell them to whitelist your emails. This is basically asking your subscribers to tell their email client you aren’t spam.

Not sure how to set that up? Check out this resource on how to whitelist an email address with Gmail, Outlook, or Yahoo.

This is a simple action that helps in a couple of ways.

For starters, subscribers can be sure they’ll keep receiving the emails they signed up for. Also, having more people whitelist your emails will increase your sender reputation, and your inbox delivery rates will be higher overall.

Again, you’ll want to do this in your welcome email. Your readers are still excited about the content they just signed up for, and your brand is fresh on their minds.

This is the perfect time to ask them to whitelist your future content.

6. Tell Gmail Users to Drag Emails from Other Tabs to Primary Inbox

Even if your email didn’t go to spam, Gmail users might still have trouble finding your emails because they have been filtered into other tabs like Social or Promotions.

We classify these as spam because, let’s face it, people rarely look in these folders either.

To prevent this, simply ask your subscribers to drag your emails from their Promotion folder to the Primary folder.

Here’s what that looks like from an email we got from MemberPress:

Move email to Primary inbox

Now, your Gmail subscribers will always receive your emails in their primary inbox.

7. Teach Subscribers How to Keep Your Emails Organized

Your emails are important to your subscribers, but they also get a lot of other emails. Help them find your emails easily by teaching them how to organize them into a special folder.

Also, remember that engagement significantly affects your inbox placement rates. Helping your subscribers keep track of all your future emails will help keep your emails out of spam for good.

Give your subscribers these instructions to help them organize emails from you:

How to Organize Emails

  1. Create a special folder where you can archive emails after you have read them.
  2. Don’t set up filters to automatically direct emails into these folders, or you may miss something.
  3. After you’ve finished reading an email, manually move it to the folder.

You would be surprised how many of your readers would gladly set up this special folder for your future emails. One of the biggest reasons many people don’t organize their inboxes this way is that many companies fail to ask.

Now that you have seven ways to prevent your emails from going to spam, we’ll look at a few more resources to help you stay in your readers’ inbox.

We’re talking, of course, about running your emails through spam filters before hitting Send.

Spam Filter Testing and Spam Checkers

Still worried that your emails might go to spam? If you follow all of the above tips, and you’re still having a problem with your emails getting sent to spam, here are some spam checkers that you can use to test your emails for issues.

1. Litmus


Litmus is a suite of email optimization tools that includes a spam checker. Here’s how it helps you keep emails going to spam:

  • Verifies that your email authentication, such as DKIM, DomainKeys, SenderID, and Sender Policy Framework, is set up correctly
  • Gives you a spam score, which advises you on why you got that score and how to improve it

2. Mail-Tester

mail-tester gives an easy-to-understand score

Mail-Tester is a free spam-checking tool that gives you an easy-to-understand score out of 10 on a scale of spamminess.

You’ll have to check each email manually, but it checks to see if you’re blacklisted, DKIM, and the quality of your email message, as well as doing a SpamAssassin check.

3. IsNotSpam.com


IsNotSpam is a free spam checker that you can try if you don’t have the budget for Litmus.

You’ll have to check each mail manually, and it doesn’t have a comprehensive testing capability. Still, it will check your Sender Policy Framework, SenderID, and DKIM to make sure they’re set up properly, and it will do a SpamAssassin check to score your email content.

  • Violation of Gmail Policies: Not adhering to Gmail’s bulk sender guidelines can result in emails being marked as spam. Ensure compliance with their policies.
  • Feedback Loops: Not using feedback loops to understand why users mark your emails as spam can prevent you from making necessary adjustments.

  • Changes in Email Algorithms: Email providers constantly update their spam filters. Even small changes in their algorithms can affect your email deliverability.
  • Sender Reputation Decline: If your emails suddenly start getting marked as spam by recipients, it can quickly harm your sender reputation.
  • Blacklisting: Your sending domain or IP could have been blacklisted by major email providers if they detect suspicious activity.

  • Adjust Spam Filters: Check your email settings and adjust the spam filters to be less aggressive. Be cautious as this might increase the risk of actual spam getting through.
  • Mark as Not Spam: Regularly check your spam folder. If legitimate emails are found, mark them as “Not Spam” to train your email provider about your preferences.
  • Add to Contacts: Adding the sender’s email address to your contacts list can help ensure their emails arrive in your inbox.
