Every time i tried any emailing i got immediately hosting suspended account suspended kicked off chased away murdered. And all i tried was contacting my previous customers and/or site members.
I never managed to successfully and sustainably email at any scale. Im not talking big numbers, im talking like 1 email per person per month from a list of 5.000 emails. So 5000 emails per month, maybe even less.
Anyway email marketing is powerful, i just find it annoying because for one the bans and for two you dont even know if youre hitting inboxes.
Actually after reading the original post i kinda thought the poster wasnt being honest, something smelled. But after reading his other replies, he seems legit. Good luck dude
