Much of the timing depends on the number of lists (or tags), follow-up sequences, subscriber sources and automations you currently have. Usually the migration takes 2 up to 4 weeks.
Each migration will be analyzed on a case-by-case basis and we’ll provide you with an estimated timeframe beforehand. If your migration is complex or there are many automations, emails and forms to recreate, we might need your help to make sure things are up and running by your migration’s close date.
Note: It’s usually best to let currently active subscribers finish the workflow in your old tool, and let new subscribers start the MailerLite workflow. There's no feasible way to stop your current subscribers mid-sequence, import them to MailerLite and have them start from where they’d left off.
