I sent out my first mass email a short time ago. All couples received duplicate emails. I understand the primary and secondary entries in the Profiles table for couples. The secondary used to store the information regarding the 2nd person. This secondary entry has EmailNotify set to 1 (true). This should default to 0 (false) for the secondary entry. Additionally, when the primary couple profile is edited by the member and Receive mass emails is unchecked, only the primary entry in the Profiles table is updated to EmailNotify = 0. The secondary entry in the Profile table is left with EmailNotify set to 1 (true). Dolphin 7.0.4.
