This trigger starts a workflow on a specific date. If you like to send anniversary messages for birthdays check out the Anniversary Trigger.
There are two types of dates Mailster can use:
Specific Dates
This workflow gets triggered for all subscribers on the defined date. Narrow down your selection using conditions. If you only send a single email in this workflow consider using a regular campaign instead.
Custom Field Dates
Use this trigger to send emails based on user values.
Offset
Define an offset to move the exact time before or after the defined date. This is useful if you like triggering the workflow in advance or after some time.
