When you switch to MailChimp from another email service provider (ESP), you may need to reconfirm your subscriber list. If you're currently sending to the list you manage, and you've tracked your bounces, unsubscribes, and abuse complaints, you're probably all good to use MailChimp. Just remember when you import your subscribers, to only import the active email addresses and then import your unsubscribed and cleaned addresses separately.
Other ESPs handle bounces differently than MailChimp so double check that your bounces aren't included when you upload your subscribed addresses.
Below are some cases in which you'll need to reconfirm your list before you use it in MailChimp.
- Your current list hasn't been recently or regularly cleared of unsubscribes and bounces.
- Abuse complaints weren't being handled, or were not being adequately handled.
- You haven't sent to your list in a while.
