We would also like to be able to send to more than one email address for cases where there are joint tenants as well as those tenants who tend to chop and change their email addresses...

Would really appreciate this as most of our tenants are not your typical email users and we're therefore having to waste our time on phone calls -  or texting tenants personally which creates issues for team working.  I myself, would also prefer text reminders rather than email reminders for most things.
