Run a workflow on the anniversary of your subscribers, like birthdays or membership dates. If you would like to start a workflow on a specific date (and not on the anniversary of that date) check the Specific date Trigger.
There are two types of anniversary 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. This is useful for anniversaries like birthdays. To trigger this campaign every year you have to define repeats below.
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.
