MailerLite
See the installation steps to learn how to install our app and change the form name
Before you start
- A MailerLite account. A group is optional — see the note below.
- An API token — Integrations → MailerLite API. The token is a long JWT; copy all of it.
No groups yet? FormRelay offers All subscribers (no group) so you can start without creating one. Create a group in MailerLite first if you want list-specific targeting.
Step 1: Set Up MailerLite Integration
- In your App Dashboard, go to the Sites menu and click on your Authorized Webflow Site.
- Here you will see all your forms across the site.
- A form can send to several destinations, but only one of each kind. Adding a second MailerLite destination to the same form is not possible; edit the existing one instead.
- From the left-hand menu, click on Integrations. You will see available categories such as:
- Apps & Platforms (Notion, Slack, Discord, Airtable)
- Email & marketing (HubSpot, Mailchimp, Klaviyo, Brevo, MailerLite, EmailOctopus, Moosend, Omnisend, Sender)
- Automation & Webhooks (Webhook, Zapier, Make, etc.)
- Under Email & marketing, click on MailerLite.
- Give the connection a recognizable name (e.g., “MailerLite integration - Contact”).
- Paste your MailerLite API key (For details, see section 4: How to create a MailerLite API key).
- click "Save".
- After clicking "Save", your added MailerLite integration will appear under "CONNECTIONS".
- You can edit or delete the connection at any time.
- How to create a MailerLite API key
- In your MailerLite Dashboard, go to "Integrations".
- From the menu, under MailerLite API -> API, click Use.
- Click "Generate new token".
- A new popup will appear:
- There Enter token name (e.g., “FormRelay by Faizatech” ).
- Choose IP restrictions "All IPs allowed / Enable IP allowlist".
- Click the checkbox "Terms of Use".
- Click "Create token".
- Your new API token will be displayed.
- Copy or download the key and store it securely — you’ll need it to connect your app.
- Go back to the Forms menu.
- Choose a Form from your authorized Webflow site.
- Click "+ Add destination".
- A popup will open with a dropdown for Integration → Pick an integration.
- Select your MailerLite integration from the dropdown.
- Configure Field Mapping by matching each field from your Webflow form to a property in your MailerLite Subscribers -> All Subscribers.
- Click Save when finished.
- Test the integration:
- Go to your published Webflow site.
- Fill out and submit the form.
- You will see the data appear in your MailerLite Subscribers -> All Subscribers within a few seconds.
✅ Your MailerLite integration is now successfully set up and ready to sync form submissions.
Troubleshooting
| What you see | What it means |
|---|---|
| Only All subscribers (no group) is offered | The account has no groups. That option works fine; create a group in MailerLite if you want list-specific targeting. |
Still stuck?
Open the site's Logs page in FormRelay. Every attempt is recorded with the destination's own error message, and you can Replay a failed delivery once the cause is fixed. Delivery & Retries explains what the statuses mean.
