Linking MailerLite as a source

Alpha release

This source is currently in alpha. The interface and available tables may change.

The MailerLite connector pulls your MailerLite email marketing data into the PostHog data warehouse.

Adding a data source

Go to the sources tab of the data pipeline section in PostHog.
Click + New source and then click Link next to MailerLite.
You need a MailerLite API key, which you can create in your MailerLite integrations settings.
Back in PostHog, enter the key in the API key field and click Next.
Select the tables you want to sync, set the sync method and frequency, then click Import.

Once the syncs are complete, you can start using MailerLite data in PostHog.

Table	Description	Sync method
`subscribers`	Subscribers in your account	Full refresh
`campaigns`	Email campaigns	Full refresh
`groups`	Subscriber groups	Full refresh
`segments`	Subscriber segments	Full refresh
`fields`	Custom subscriber field definitions	Full refresh
`automations`	Automation workflows	Full refresh
`forms_popup`	Pop-up forms	Full refresh
`forms_embedded`	Embedded forms	Full refresh
`forms_promotion`	Promotion forms	Full refresh
`webhooks`	Configured webhooks	Full refresh

Incremental tables sync only new or updated records on each run. Full refresh tables reload all data on each sync.

The MailerLite API exposes no server-side timestamp filter on any list endpoint, so every table is full-refresh only.
