I sent my first email and all went... fine... there were a few glitches but suffice to say it was ok.....And then came the time for me to send a second email and to update my marketing list and problems started. They implemented this thing called Hydra and Hydra is an AI, it has no idea what it is doing and it's just randomly blacklisting things as these are EMAILS I HAVE PHYSICALLY COLLECTED FROM PEOPLE. AND I HAVE THEIR OPT-IN!!!!!!! Customer service did not give a damn and were of no use. I responded immediately to verify my info but there is a 24h wait time period to get this done and I had to have my email sent ON THAT SAME DAY!!!! Suffice to say I stayed up late with a competitor which accepted my list JUST FINE. These people are idiots. Who lets an AI make such important decisions??!!!
