    Preventing multiple confirmation emails on PATCH or PUT to Lists/Member endpoint

    Tagged: Marketing, Update

    What

    It was possible to force multiple confirmation emails to be sent to a member when using identical PATCH or PUT requests to the Members resource. We’ve corrected this behavior by preventing the duplicate confirmation emails from being sent.

    Why

    Before this change, multiple confirmation emails would be sent to a member’s inbox, which could potentially be used for abuse.
