Verify Hotmail email address account, hotmail checker, validation

Hotmail email verification progress

Hotmail, Live, MSN and WindowsLive email provider is one of most used providers in the world. So task of hotmail account verification is very important for us.
Speed of hotmail validation (bulk Hotmail/Live/Msn/WindowsLive checker) is about 1,000,000 emails per day, but sometimes our service is overloaded and speed can be lower.
There are three type of Yahoo mail account verification:
  • bulk email checker - this is most recommended way, you can verify CSV file with emails (up 4,000,000 per one file)
  • verify email list - created for user's who what instant verification through our web interface (up to 30 emails per click)
  • email verification api - you can verify emails one-by-one from your software or web project
Prices for Hotmail/Live/Msn/WindowsLive email verification are the same as for other emails, but speed lower.

Verify email list in two easy steps!

Hotmail verification notices

As you know, there are lots of third party services/software that verify hotmail emails, our service working good but verification of some little part of email addresses (we will call it "unverifiable address") are impossible and our service mark it as "valid". We try to verify this addresses on different verification software and services and they marking it as "valid" too, so it's issue of all verifiers.
Now more about this "unverifiable addresses"... If you will try to send email letter to "" you will get bounce "550 Requested action not taken: mailbox unavailable" during email send process, our service will mark this email as "invalid".
But if you will try to send email to unverifiable address - your letter will be accepted and all will looking like email address really exists, but you will receive bounce letter from "" during next two minutes with text:
This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.
That is why it's unverifiable address, we have no idea why it's going but some little percent of hotmail emails are "unverifiable addresses".
