What email service do you use for manual spam ?

I tried gmail to join those spam forums and sites manually, but most of time, I can't receive the account verification email,
I don't know how those spam accounts get verified...

so I'm curious what email service do you use for the accounts registration ?

Im not into spamming but i know warmed gmail get good inbox results but in 2022 gmail is so sensible you gonna need to buy alot of accounts as they will get blocked fast asf

You will find so many PVA creators for gmail just supply proxies it should be good. Since its for spamming you cant expect accounts to be survive for longer time. Simply link all accounts with 49 emails per hour from each gmail Etc.,

Good luck
