MailerLite is an email marketing platform for creating newsletters, automations, and landing pages. The Kirki MailerLite integration automatically adds new form submissions from your website as subscribers to a selected MailerLite group.
What Is the MailerLite App
The MailerLite integration connects your Kirki forms with MailerLite. When someone submits a connected form, their information can be added to a MailerLite group so they can receive newsletters and other email automations. This is useful for site owners and small businesses that want to automatically grow and manage their email lists.
What You Need Before Connecting MailerLite
Before configuring the integration, make sure you have:
- An active MailerLite account.
- At least one Group created in MailerLite where new subscribers will be added.
To connect MailerLite to Kirki, generate an API token in MailerLite, install the MailerLite app in Kirki, and paste the token under Configure.
How to get MailerLite API Token
- In the left sidebar of your MailerLite dashboard, select Integrations.
- Find and select Developer API (also labeled MailerLite API).

- Click Generate new token.
- Enter a name for the token.
