Bring the list, and its consent
Export your audience from Mailchimp as CSV, including how and when each person subscribed. Under section 69 of POPIA that record is what lets you keep emailing them; see the POPIA email marketing rules.
Unsubscribes come too
Bring your unsubscribed and cleaned contacts across as well, so they land on the global suppression list and are never emailed again.
Authenticate your domain
Gmail and Yahoo expect SPF, DKIM and DMARC and a one-click unsubscribe from bulk senders. The setup wizard checks your domain before the first send.
Templates and automations
Save a design once and reuse it on every send. Welcome and follow-up journeys run as automations on Growth and Scale.
