Can anyone tell me the fastest method for determining whether an email address is on a specific list?
At the moment, I'm using List/get_active_subscribers - but our lists have 100k+ subscribers, and with the 1,000 entry paging limit, it's taking a long time to run.
Either of these functions would be extremely helpful :
- given an email address and a list ID, return "true" if the email address is subscribed to that list.
- given an email address, return all list ID's the email address is subscribed to.
The second of those cases does already exist, but it's located in the "clients" section as the "lists for email" endpoint:
It returns all lists belonging to the provided clientID which contain the given email.
Hope that helps.
