Let users subscribe to receive email notifications from a form

Hi,

First time I share something here, but let's give it a shot.

Say you have a form, called Form A.  Now let's say you want users to be able to subscribe to a mailing list, so they get an automatic email notification every time a new entry is submitted with Form A (by any user).  This is how I did it:

(1) create a new form, Form B, with an email address field.  This is the form where users can enter their email address to subscribe to the mailing list.

(2) create a view, based on Form B.  This view is probably the simplest view you will ever make: it should just be a comma-seperated list of all entries from Form B.  In other words, a comma-seperated list of all submitted email addresses.

(3) go to the settings tab of Form A, and create a new email notification.  In the 'to' field, add the shortcode of the view that you created previously in step (2).

That's all :-).  As an alternative, you can also choose to add the email address field into Form A, instead of creating a seperate Form B.  Obviously, the view in step (2) will then also be based on Form A.  However, if you use this approach, a user can only subscribe to the mailing list if he also submits a full entry of Form A.

So, hopefully some of you may find this useful.  Maybe there are alternative or easier ways to accomplish the same result, but this approach worked nicely for me.
