As of July 20th, GetResponse has made the following change to how duplicate subscriptions are handled:

If a person who’s already signed up adds their email address again to the same campaign, they are reset to the beginning of the follow-up cycle and emails are sent to them from the beginning (this may include the confirmation email and/or the “day 0″ instant response).

Example:

1. john@doe.com signs up to list “abc” for the first
time on January 1st, and gets the instant (day 0) response.

2. By January 9, john@doe.com receives 8 out of 9
follow-up emails from GR (so his cycle status is
8/9)

3. On January 10, he resubscribes. His cycle is
therefore RESET to 0/9 and he gets the “day 0″
instant message.

4. The cycle goes on…

Re-entering Information Via Imports
When a duplicate is imported to the list – we check if there are any new custom fields for this email address at the new subscription – we update it. Cycle is not reset in this case.

Kind Regards
