Mailerlite is a platform platform. FluentCRM handles a contact submits a form or a tag is applied on your WordPress site. Mailerlite is where that data needs to go. Here is how to connect them without Zapier or code.

Why not just use Zapier?

For connecting FluentCRM to platform, a cloud automation service adds cost and a dependency on an external server. AFI runs on your site with no task limits.

What you will need

  • A WordPress site with FluentCRM installed and configured.
  • A Mailerlite account.
  • The Advanced Form Integration plugin (free from WordPress.org).

Connect Mailerlite to AFI

Mailerlite uses OAuth 2.0 for authentication. In AFI → Settings → Mailerlite, click Authorize and grant access. This is a one-time step.

Setting up the integration

1. Create a new integration

Go to AFI → Add New. Name it FluentCRM to Mailerlite.

2. Pick your trigger

Select FluentCRM as the form provider. AFI fires when a contact submits a form or a tag is applied, giving you access to contact name, email, phone, tags, and custom field values.

3. Select Mailerlite as the destination

Choose Mailerlite from the platform dropdown and pick Add Record. This creates a record in Mailerlite.

4. Map fields

Match each Mailerlite field on the left to the corresponding FluentCRM field on the right. Common mappings include contact name, email, phone, tags, and custom field values. You can also use smart tags like {{_submission_date}}.

5. Add conditions if needed

Only want to send certain records? Set up a conditional rule based on any field value.

6. Save and test

Click Save Integration. Trigger a test event in FluentCRM. Check Mailerlite to confirm the data arrived. If anything looks wrong, open AFI → Log to see the exact request and response.

Free vs Pro

The free version maps name and email to Mailerlite with unlimited records. Pro adds custom field mapping. No per-record fees on any plan.
