Save MailerLite Classic Group Subscribers to Airtable

Save MailerLite Classic group subscriber names and emails to Airtable.

Setup

Use a MailerLite Classic account. This workflow uses Classic’s subscriber.add_to_group event and payload; it does not accept the differently named event from current MailerLite accounts. Create an Airtable table with Name and Email fields and connect Airtable. Set the base ID and table name in the Airtable node.

In Open Flow, activate the webhook and register its URL with the MailerLite Classic webhook API for subscriber.add_to_group. In n8n, connect the MailerLite Classic credential to the trigger and Airtable to the append node; activation registers the trigger.

Behavior

Each event contributes the subscriber’s name and email to a new Airtable record. MailerLite can deliver several events together; Open Flow writes the matching events one at a time in delivery order. In n8n, Airtable V1 may send up to ten records in a request; in Open Flow each request contains one record. A failed or unknown write stops later writes. The workflow does not deduplicate or retry writes, so inspect Airtable before replaying a delivery.

The source’s Classic trigger does not validate the MailerLite signature, and this Open Flow webhook likewise does not authenticate callers. Anyone with its URL can submit records. Use a deployment that restricts access if that is required for your Airtable. The webhook acknowledges admission before downstream writes finish.

Changes to the source

Replace the private Airtable base with configuration. Open Flow uses a manually registered Classic webhook; n8n retains the source’s Classic trigger.
