We have Enabled the Re-subscription Emails ( Content->Content Settings-> Email).
Scenario is user is opted out of email. On the landing page form when a user enters his email and tabs out, as desired, he is displayed the following link -Looks like you’ve opted out of email communication. Click here to get an email and opt back in. On Clicking the link, re-subscribe email is received and the same is reflected in the contact timeline
Question/Problem: If we try the above step again, the link is displayed. On clicking the link again, the re-subscribe email is not received (we may receive it 2 or max 3 more times but stops after that for couple of hours). The contact timeline reflects that. On following day we try the same, we get the same behavior, email is received 1,2 or 3 times and stops after that. Is there a filter ? We just want to understand the working so expectations can be set. ( Note: it is the same user with the same opted out email address trying to re-subscribe)
