Editing existing profile with s2member and MailChimp

#1

I’ve got s2member working with MailChimp API. While testing the ability for members to modify their email address after they are registered, I discovered that MailChimp is sending 2 identical confirmation emails to the new address. The first one, if clicked, appears to trigger the second one. If the second email is clicked, the address is updated in MailChimp. These appear to be the same confirmation messages used when a new member is added. Any idea how to configure either of these programs so only 1 confirming email is sent when editing a profile?

I neglected to note that the confirmation emails for changes to profile are also the same ones sent for first-time registration. Shouldn’t these be related to profile editing?

I was using “Brand A” plugin to communicate between s2member and MailChimp. The moment I deactivated the plugin and activated “Brand B” the double messages went away. MailChimp still persists in sending activation messages whenever I change the email address, as opposed to recognizing that this is a modification being by an already registered member. The previously registered email is removed in MailChimp and eventually gets replaced when the member confirms his change. If a user ignores the confirming email, they won’t get updated in the MailChimp list. I guess the only workaround is to force a sync periodically between the WP users list and the MailChimp list to guarantee that all active users are included in the MailChimp list. Actually I’m beginning to think that it’s better to export the WP users to a service like Amazon SES and eliminate MailChimp altogether.
