Should I be using POST or GET in my AJAX call?  User fills out a form, the email address is checked to see if it is already in the DB.  If not, the email is entered into the DB and then a confirmation email goes out to that person via plain text php mail();

it depends on where the request posted to, technically you need to check the receiver point whether it accept POST/ GET requests.

since you're posting User details in your form, a POST request is preferred.

the validation of the email address need to be done at server end.
you can use either post or get for an ajax call. It doesn't really make a difference.

By the book, GET should be used for querying a database and POST should be used for updating a database, but again, it doesnt make a difference.
