Guide for MailerLite and MailerLite Classic
MailerLite offers two versions of their platform, MailerLite and MailerLite Classic. You’ll need to connect to the specific version you are using or your leads will not be captured! We provide a walk-through for each version of MailerLite in this guide.

Add Extra Fields
Field Mapping
This integration supports Field Mapping, so you can easily add radio buttons, phone fields, text areas, number fields, lists, and more!
Before you begin using Field Mapping with MailerLite, please consider the following:
- Custom fields are referred to as Fields in your MailerLite account.
- The following custom fields arereserved in MailerLite and cannot be mapped to:
Name(name)Last Name(last_name)Phone(phone) (use the Phone field to send data to this Field)Coupon Code(coupon_code) (the Coupon Code won when creating a Gamified spin-to-win campaign)Coupon Label(coupon_label) (the Coupon Label when creating a Gamified spin-to-win campaign)Privacy Consent(privacy_consent) (when using the Privacy Consent checkbox)
- Automatically created custom fields are added as text fields in MailerLite. This can be avoided by manually creating your custom fields in MailerLite before mapping to them in OptinMonster.
- You can manage your custom fields in MailerLite following this guide.

Alternatively, you can add any MailerLite webform to your campaign using our Form Embed block.

Email Automations
To send emails automatically to new leads you’ll want to configure email automations within your MailerLite account.
The following guides from MailerLite may be helpful to get started:
Testing
We strongly recommend you test the optin form before publishing your campaign to ensure it is working as you expect.
Before you begin, please be aware of the following details when testing MailerLite integrations:
- Previously submitted or already subscribed leads may be treated differently by MailerLite than new leads. For this reason, we recommend using a completely unique email address each time you test submit your campaign’s form. You can use a free tool like TempMail.io or learn how to create unlimited unique email addresses from a single Gmail account.
- If the lead is captured in MailerLite but you do not receive any automated emails it indicates the integration from OptinMonster to MailerLite is correct, and the issue is with the automated email configuration. MailerLite controls email automation exclusively. If you require assistance in troubleshooting email automations we recommend reaching out to MailerLite support directly.
Get started testing with the Live Site Inspector tool explained in our guide on how to test an OptinMonster campaign.
Spin-a-Wheel Support
If you are configuring a Gamified spin-to-win campaign, spin-a-wheel support is not available at this time to send the coupon data to MailerLite.
FAQs
Can I send leads to more than one Group?
Yes! See our Lead Sharing guide to accomplish this.
How do I configure single or double opt-in?
See our guide on single vs. double opt-in.
Is it possible for me to add a phone field to my campaign?
Yes! You can add a phone field. Learn how to capture phone numbers with OptinMonster.
How quickly are leads sent to MailerLite? Is there a delay?
There is no delay. Lead submissions are sent to MailerLite in real time. OptinMonster will not perform the Button Action (like showing a success view or redirecting the user) until we get a confirmation that the submission was successfully received.
Even if your campaign is integrated with multiple Email Service Providers (ESPs) at the same time, OptinMonster sends the lead data to all connected integrations simultaneously, without delay.
Why doesn’t my conversion count match the number of leads in MailerLite?
It is normal for these numbers to differ. There are some reasons for a discrepancy between the conversion count in OptinMonster and the lead count in MailerLite:
- Double Opt-In: If your email service is set to require double opt-in, a user must first click a confirmation link in an email before they are officially added to your list. OptinMonster records a conversion as soon as the form is submitted, but MailerLite won’t count them as a new lead until they confirm.
- Existing Subscribers: OptinMonster records a conversion each time a form is successfully submitted, provided that conversion tracking is enabled on the submit button. However, if an existing subscriber fills out your form again, MailerLite will likely not add them as a new lead, as their email is already on your list.
- Conversion Tracking Enabled on Other Blocks: Conversions can be tracked on various elements, not just the form submission button. For example, if you have conversion tracking enabled on an image link and a visitor selects it but does not fill out the form, OptinMonster will still count a conversion. This increases your conversion count without a lead being submitted.
- Integration Failure: If the integration experiences a temporary issue, form submissions will still count as conversions. However, the lead data may not be sent to integration.
- Lead Filtering: When a user signs up with a disposable email address or is flagged as suspicious, the campaign will still record a conversion (form submission), but your integration platform may reject or filter out the lead.
