Quick summary
This demo shows how to integrate MailerLite with Systeme.io using a Zapier automation that adds or updates a subscriber every time a new sale is recorded. No code is required — the entire Zap is configured through Zapier's visual editor in under ten minutes.
Steps
- Log in to Zapier and click "Create" then "Zaps" to begin building a new automation.
- Click "Trigger" to open the trigger configuration and select your Systeme.io trigger event.
- Search for and select "Systeme.io" as your trigger app in the app search field.
- Select "New Sale" or another relevant trigger event from Systeme.io's available options.
- Connect your Systeme.io account or choose an existing connection from the account dropdown.
- Click "Action" and search for MailerLite to set it as your action app.
- Select an action event such as "Create or Update Subscriber" to add Systeme.io contacts to your email list.
- Connect your MailerLite account when prompted to authorize the integration.
- Map your Systeme.io fields — email, name, and purchase details — to the corresponding MailerLite subscriber fields and groups.
- Run a test to verify that Systeme.io data is syncing correctly with your MailerLite account.
- Click "Publish" to activate your Zap and start the live automation.
