The email system is fixed. Good news! I sent a test message out to all my subscribers and it went through perfectly. I titled the email “A Test of the Rubber Mallet Comics email System … and your subscription list.”
When my email got to my mailbox it was bounced to spam, which is probably going to happen to you. Check your spam and your trash and hopefully you’ll be able to mark our email address (firstname.lastname@example.org) as “not spam”.
