When a subscription form is submitted a new member can now automatically receive one welcome email message while renewing members can receive a different one.
A new member probably needs a different kind of welcome message sent to them after submitting a subscription form. Two different email messages can now be set up so when a new member successfully subscribes, they will be sent one email message while a renewing member can be sent a more custom message pertaining to their continued membership on your site.
The messages are set up per member plan so they can be custom for every member plan or the same for each plan. Whatever works best for your site can be set up. These two messages can also be the same per member plan as well.
