My contact lists in mailchimp are updated daily via api. Each contact has a "last visit date". My purpose is to create an automation campaign with two emails, which will be sent after:
1) 60 days from last visit;
2) 120 days from last visit.
Which type of automation campaigns do I choose: specific date or recurring date? I cannot understand the principal difference between these campaigns. Both of them allow to send emails after 60/120 days from last visit.
Thanks a lot
