but the problem is that it will be high bounce rate, and the smtp will be suspended, even some email marketing account will be suspended easily, no matter personal vps or commercial smtp, validated email address will decrease the bounce rate, and inbox rate, right?When you have an email list, then spending money to find out which of those emails are valid will cost you more than what you spent on purchasing or gathering (generating) the email list. Apart from that there will be time involved to check if the emails are valid or not. That's why when someone has an email list then ideally emails are shot out to all the emails in the list without bothering about some of the emails being invalid.
no, it's email validation process, to eliminate bouncesDo you mean PVA aged gmail accounts ? There are lots of them on the market
There are tons of open source tools, it's just needs to be a convenient service, and scalable for user.I already made a tool to verify large email lists, maybe I should make it public?

There are many new domains appeared everyday and it's quite hard to connect and verified them. I think that's the point to make this service is not cheap.I think email validation and verification is very important for email marketing, why no one do such business here? it's kinda expensive on the market.
