how to verify a large volume email addresses.

[Lucky]

Hi Guys,

I have a large volume database,about 200m and the quantity is growing more and more,there are at least 20% address is invalid.I guess no email marketing provider accepts such a bounce rate,Is there any better way than use bulkemailchecker.com or kickbox.ro....?

Nope, a validation service is your only chance.

For pop emails (no hotmail, no gmail, no yahoo, no aol ...) :

1 - Check RFC email format.
2 - Check if domain exist.
3 - Check MX.
4 - When you send with your "verifed emails", add a % of unverifed email.

For no-pop I have a custom system to clean invalid and spamtraps.

I'm interested in your system to debug emails.
