MailerLite Integration

2 min readUpdated April 20, 2026

MailerLite is a clean, straightforward email marketing platform popular with small businesses and creators. WP Smart Consent integrates with MailerLite via the MailerLite API v2, forwarding opted-in contacts to your MailerLite account in real time.

What You’ll Need#

A MailerLite API key. To generate one, log into your MailerLite account, go to Integrations → Developer API, and copy your API key.

Setting It Up#

In the WP Smart Consent dashboard, go to Integrations and find the MailerLite card. Enable it, paste in your API key, and save. WP Smart Consent will connect to your MailerLite account and populate a group dropdown with your available groups. Select the group or groups you want opted-in contacts added to.

Group Selection#

WP Smart Consent supports selecting multiple MailerLite groups simultaneously. If you have more than one group selected, opted-in contacts will be added to all of them in a single opt-in event.

What Gets Sent#

When a visitor opts in, WP Smart Consent forwards their first name, last name, and email address to MailerLite. The contact is added to your selected groups immediately.

Works Alongside Other Integrations#

Enabling the MailerLite integration doesn’t affect any of your other active integrations. Each destination is independent — a single opt-in event will be forwarded to MailerLite and every other enabled destination simultaneously, and logged with the source integration that captured it.
