You may want to consider adding a few more options in your communication emails as currently you only offer days before expiration and days after paid for the auto emails... I am selling yearly memberships that are set to renew each year (serial). In your email choices there is no after renewal... we don't want them to get the new member email after a "paid" trigger as that only works for the first email to a new member... no trigger for existing members that are renewing. you have the trigger to let them know days before renewal, but no way to send an after renewal email.
Thanks for your help
