Customised automated emails responses for different memberships

Hi,

I'm looking to see whether I am able to send a different email depending on the type of membership a user selects. I believe that this can be done by activating the Automated Email Responses addon, and choosing the corresponding template. Am I correct in doing this or is there another way?

Also, I presume that the welcome email sent by WordPress after a user signs up including their selected username and passwords is a separate entity not controlled by membership 2?

Many Thanks.
