Fix the issue which is not allowing me to send out even 1 email :( I am nowhere near the limit and this didn't happen until just recently.
Is there a problem with your software? You say to "Please upgrade to a paid account if you need to send mails to many recipients." I do not need to send mails to many recipients. I would like to be able to send ONE email today. This does not encourage me to sign up for future service.
