Someone fills in a form you built with Contact Form 7, and a new subscriber appears in your MailerLite group. Every field maps straight across the instant the form is submitted — a direct, real-time connection that runs entirely on your own WordPress site.

Everything you need to know about the Contact Form 7 & MailerLite integration
No. Install Integrazo Automator, authorise MailerLite once, pick the form as your trigger, map the mail tags to MailerLite fields and switch the connection on. There is no webhook URL to paste and no JSON to write.
The one you pick when you build the connection. Every subscriber it adds goes to that group, with the fields you mapped.
Yes. Every one of your mail tags is offered against every standard and custom field on your MailerLite account — pick the ones you want mapped.
No — MailerLite matches subscribers by email address, so a repeat submission updates the existing subscriber rather than creating a second one.
Yes. Add a filter condition on any mapped field — contains, equals, starts with, is empty and the rest, combined with AND/OR — and only entries matching it are sent to MailerLite. Everything else is skipped and still shows up in your Logs.
The run is logged as failed with the error MailerLite returned, and the submission is still saved in WordPress — nothing is lost. Once the problem is fixed, the next matching submission goes through as normal.
No. The connection runs on your own WordPress site and talks to MailerLite directly. The OAuth token is encrypted in your database, and there is no middleman service holding a copy of your data.
The core plugin is free on WordPress.org and covers a single connection. Pro adds unlimited connections, multiple groups per connection, and custom field mapping, and priority support.
