Announcing OptinMonster Content Lock Feature – Easy Way to Get More Email Subscribers

Content locking has been a long requested feature of OptinMonster. After adding real-time behavior targeting and completely redesigning the builder in OptinMonster 3.0, one of the first things in our list was to bring content locking to OptinMonster.

What is Content Lock?

Content Lock allows you to block portion of your content for subscribers only. Content lock requires users to enter their email address in order to see the content. If a user is already an email subscriber, then they will see the full blog posts.

Those who aren’t subscribers, will see a blurred version of a blog post.

Here’s a content locking example:

OptinMonster Content Lock Example

This is great for blog posts and long articles because it’s one of the easiest ways to get more email subscribers.

Normally content lockers are sold as separate WordPress plugins or scripts. At OptinMonster, it’s included for free as part of the Plus and Pro license.

How to Add Content Lock in OptinMonster

Simply login to your OptinMonster account and create an after post / inline optin form. Under the Optin tab, you need to turn on Content Blocking.

Configure the Content Blocking options for your After Post / Inline optin in the Optin panel of the builder.

OptinMonster allows you to select from two blocking methods:

  • Obfuscation – Blurs out the text below the optin (default).
  • Removal – Removes the text completely below the optin.

Once you’re done, simply embed it in your blog post or content area.

If you’re using WordPress and want to automatically add OptinMonster content locking after specific paragraph, then you can use the embed code in combination with Insert Post Ads plugin.

Detailed step by step guide instructions on how to use OptinMonster’s Content Blocking feature.

What’s Coming Next?

Our team is working on adding several new templates for each campaign type. Over the next few weeks, you will see a lot of new themes being added to OptinMonster.

If you haven’t seen our new Display Rules Engine that we launched in OptinMonster 3.0, then you should definitely check it out. We’re taking conversion optimization to the next level.

Please try out OptinMonster Content Lock feature and don’t forget to share your success stories with our team.

    Hi Syed,

    Looks like promising but I have a question, what about fake emails to unlock the content? Because with content lock, it’s very simple to put as email “” and the content will be unlocked but the email which is a garbage email will finish in our mailing list and will be considered as a bounce by email provider.
    How is this managed?

    1. Syed Balkhi Syed Balkhi says:

      Hey Quentin,

      There’s no easy way to verify an email address. For example, if I add and let’s say it belongs to a Joe there, it’s a real email. It may not belong to me, but it’s a real email and will pass all checks. Anytime you do single optin, you risk getting fake email addresses, but only sophisticated users do that. An average user will add their real email.

      However the purpose of content locker is to lock otherwise free blog content and use it as an easy way to grow your email list.

      If you’re using WordPress, then you can programatically load this on all posts that are over 1 year old and let your old posts get you new email subscribers.

      1. Quentin says:

        Thanks Syed for your feedback, understand it well and it offers another way to get new email subscribers (for the average users). Great work!

  2. Alex says:

    This feature is great, but I don’t want to lock ALL my content. Just a section between 2 shortcodes. E.g. like lock down a report, not the whole post.

    Also, please let us know if search engines can read the locked content for SEO purposes.


    1. Syed Balkhi Syed Balkhi says:

      Hey Alex,

      Search Engines can still read your content because the obfuscation happens with JavaScript.

      At this time, you can’t lock specific sections. The best way to lock a report would be to turn it into a lead magnet and deliver it as a downloadable file.

  3. Lucian says:

    In what pricing category this falls ? I am trying to figure out which option should I sign up for. Thanks!

  4. Lucian says:

    Got it – Plus and Pro license – FREE

  5. Jason McCullough says:

    This is a great feature. Will social login (OAuth) be available as an option? As opposed to the user entering their email address? This would be a killer feature with social login.

    1. Syed Balkhi Syed Balkhi says:

      Our goal at OptinMonster is to help users build an email list. Social login is not in our roadmap at this time due to a variety of reasons (mainly privacy). At OptinMonster, we do not store any of your subscriber data. We simply pass that information to your email marketing service.

  6. Abhishek says:

    Is there a scope of having the option to lock the downloadable content?

    For example, offer an e-Book or checklist but lock it by Email subscription?

    1. Syed Balkhi Syed Balkhi says:

      There are several ways to deliver your lead magnets.

      We have covered them here:

  7. Doug Lietz says:

    It would be nice to have API integration with Aweber so that this content lock feature would check to see if the email is on my list… if YES then unlock the content immediately… if NO then have them first confirm their opt-in, after which they could be redirected back to the unlocked post content.

    PS: I am in agreement with Alex above in a previous comment, about adding the ability to protect only selected content that is wrapped in between 2 shortcodes.

    1. Syed Balkhi Syed Balkhi says:

      You can easily do this with display rules. See which cookie AWeber drops for your subscribers, then only show the form to those who doesn’t have that cookie.

      Again, it will never be 100% because people use different devices / computers so in those cases, your subscribers will see the optin form and there’s no technology that can fix that.

  8. Dan Carr says:

    What happens if you want to use a double opt-in process? Does it still work or will it unlock immediately after someone has submitted their email?

    Also, does it remember someone for a specific length of time so that they do not have to keep re entering their email on each page?

    1. Syed Balkhi Syed Balkhi says:

      It will immediately unlock the content because OptinMonster can only check successful conversion through our form (not the double-optin verification from the marketing service).

      Yes, it will remember the user for the cookie length that you set.

  9. Pauline Cabrera Pauline Cabrera says:

    Woot, I gotta try this new feature. Great addition Syed!

    1. Syed Balkhi Syed Balkhi says:

      Thanks Pauline 🙂

  10. Jesse says:

    What about the SEO implications of this? You stated “Search Engines can still read your content because the obfuscation happens with JavaScript”. However, if I were to put white text on a white background, Google would still punish you for doing that because humans can’t read it, even though the Google spider crawler can. Maybe Google can detect that the text is hidden to humans, and punish the site in the rankings.

    1. Mary Fernandez Mary Fernandez says:

      Hey Jesse,

      Check out what Google has to say about hidden text.

      Google punishes hidden text and links when they are being used to manipulate the search rankings. However, as Google stated, not all hidden text is considered deceptive, such as JavaScript for example.

      In this case, JavaScript is being used to gate the content, not to manipulate the search results or to “trick” Google. So I think it is safe to say that you will not be penalized by Google for using the Content Lock Feature.

      Hope that helps!

  11. Andrew Smallwood says:

    Hi Syed,
    Love the addition. Optinmonster has been on my radar for a while under my list of software needs. How easy would it be to add a share button or follow button to unlock the hidden text? Thanks again

    1. Angie Meeker says:

      Be default, the conversion is a subscription to an email list. However, you can use our Custom HTML Integration to create your own point of conversion (like a button, link, image, or a follow/share button). You can learn more about how to do this at Whatever HTML code you’re using, you must be able to add our conversion class class=”om-trigger-conversion” to the specific point of conversion (like the button).

  12. Eugen Popa says:

    Great stuff Syed
    I am wandering if you will make available anytime soon an option where I can offer my readers a PDF version of the article for donwload, as they subscribe to the newsletter without having to create a new optin for each article?
    Maybe I didnt know how but so far, I could not see this option.

    Thank you

    1. Syed Balkhi Syed Balkhi says:

      We don’t have the option to convert a blog post into PDF because that’s beyond OptinMonster’s scope.

      One of these plugins should be able to do the job though:

  13. Jarrod says:

    I was wondering if the display rules apply to this feature? I am looking for something that allows people to read a couple of articles but then starts gating content. This is strangely hard to find. Will this tool work that way? Allow people to see the first two pages for free and then start showing the locker if they continue to browse?

  14. Carson says:

    Currently with content lock you can simply bypass entering your name and/or email address and just press send. After pressing send, without entering a name and/or email address, the content is unlocked. This seems counterproductive and is quite frustrating. Have I missed a step in the setup process?

    1. Mary Fernandez Mary Fernandez says:

      Hey Carson, that should not be happening. Did you submit a support ticket? Please contact our support team via so that we can help you with that.
