Does MailChimp send out the final welcome email when I import my list?
No, MailChimp does not send the final welcome email confirmation to your recipients if you’re importing an already existing opt-in list. We only send confirmation emails to new members of your list if they subscribe through the form you built on MailChimp or from a form you have pointing to MailChimp that uses our confirmation process. We assume that your list has already willingly opted-in as required in our terms of use, so we wouldn’t want to force your opt-in recipients to click a link to re-confirm.
