PieSync integrates MailerLite with other apps for an automatic 2-way contacts sync. Every time you add or update a subscriber in MailerLite, it is automatically synced with the other app and vice versa—eliminating import/export!
How it works
1. Log in to your PieSync account.
2. Choose MailerLite and another app for syncing. Click Authorize for both apps. You will need to paste your MailerLite API key for authorization.
3. Choose your sync direction. By default it's synced both ways between the 2 apps, but you can choose to sync just 1 way. You can customize your sync by adding actions and conditions. For example, you can set up your subscribers based in New York to be added in a specific group in MailerLite.
That's it! Now both apps are synced!
