As a courtesy feature, perhaps three versions of renewal emails. I use auto renew and received an email stating I need to renew. Major bummer for people who do not like to click on links received by email, especially given the inability of most phone email clients not allowing a closer look at said email. Takes time to figure out if all is good or not with billing. How about a version that states your account will be renewing soon, or perhaps you need to update your billing info.
