Anybody having trouble with ReachInbox deliverability or bounce rate?

Hello fellow members, following a video from @Jay Feldman (https://www.youtube.com/watch?v=PcO0_1_F60Y), I bought reachinbox.io and started to warm 15 fresh emails. I get around 5 "Mail Delivery System" mails with failed mails, what i wonder I don't see the "Warmup filter tag" is the mails? - Is this also something that you experience? - Is this normal (ok i realize that some stop using the system)? - Does this not hurt our domain reputation? On instantly, the warm-up goes to 50 emails, should I match those setting to reachinbox?

Where is everyone from? I am from Charleston, SC.
