Hi @MarioGlad ,you can achieve your logic in a single workflow using
SPLIT activity.In Initial Query target your recipients In Split
Activity, in subset tab define a filtering condition as birthdate is not
empty (Refer below screenshot) And in General tab, Enable generate
complement as belowNow you can have 'Birthday Email' for 'Recipients
with Birthdate' transition and 'Anniversary Email for 'Birthdate is
Empty' transition.Regards,ParthaSarathy S
