You can absolutely message multiple patrons at the same time in the Patron Relationship Manager.
To bulk message your patrons:
Step 1: Go to Patron Relationship Manager.
Step 2: Filter patrons by membership types, tiers, pledge amount, charge status, or search them by a specific term.
After selecting a filter or entering a search term, you can bulk message all of the patrons who appear in this list.
For example, if you'd like to bulk message all of your processed patrons, select processed from the filter list. Or you can enter processed in the search bar to pull up this list of patrons. From here, select the message icon to bulk message all of your processed patrons.
Can I select specific patron's in my PRM to bulk message?
No. You'll only be able to bulk message folks by selecting a filter, like paid or declined, or by entering a specific search term. Then you can message everyone who appears on the filtered list.
Step3: Type in the message and hit send.
