We’ve enhanced the way candidates & contacts opt out of mass mailings. Previously, users had to only click an email link to be opted out. With the enhancement, when users click the ‘opt-out’ link, they are brought to a web page, but are then required to click an opt-out button to unsubscribe. This change was done to prevent recipients from erroneously opting out. We recently determined that beginning in February 2021 certain customers experienced recipients (contacts / candidates) of mass mail that were automatically and incorrectly opted out. We believe this issue may have been caused by anti-virus software, or other software, on the recipient’s system. The new enhancement has corrected the foregoing issue.
