I have created a mailing list with list of users. I have created a form and in the form settings, Under "Send email notification for responses to..." section, when I try to add, it is not allowing to add this mailing list. Screenshot attached.
My requirement is to send a mail to a group of people(list changes periodically-added to a mailing list ) on a form submission. How this can be achieved?
Any help on this is highly appreciated.
