Your subscription will continue and renew automatically unless terminated by IMU or until you notify IMU by email or as designated on the Site of your decision to terminate your subscription. If there are any annual, monthly, or similar periodic fees for your subscription, fees will be billed automatically to the credit card or bank account designated during the registration process for the Site or subsequently designated by you to IMU, at the start of the annual, monthly, or similar period, and at the start of each renewal period, unless you terminate your subscription before the relevant period begins. You agree to pay or have paid all fees and charges incurred in connection with your account for the Site (including any applicable taxes) at the rates in effect when the charges were incurred. If you exceed the Usage Limits of your Service Plan, you will be automatically charged for any Overages at the same rate of your current Service Plan. For Example, if your Service Plan is $100 for 100,000 Records, and you end up using 150,000 Records, resulting in a 50% Overage, then you will be responsible for a $50 Overage Charge. All fees and charges are nonrefundable, except for as stated in the Refund Policy. IMU may change the fees and charges then in effect, or add new fees or charges, by giving you notice in advance.

Hotmail Verification Notices

As you know, there are lots of third party services/software that verify hotmail emails, Our service works well but verification of some small part of email addresses (we will call it “unverifiable address”) are impossible and our service mark it as “valid”. We try to verify these addresses on different verification software and services and  mark it as “valid” too. so It’s issue with all verifiers.

Now more about these “unverifiable addresses”… If you will try to send email letter to “sdgfdfhj232146@hotmail.com” 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  try to send email to unverifiable address – your letter will be accepted and all will look like email address really exists, but you will receive bounce letter from “postmaster@hotmail.com” during next two minutes with text:

This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

       xxxxxxxxxxxxxx@hotmail.com

That is why it’s an unverifiable address, we have no idea why it’s going through but some little percentage of hotmail emails are “unverifiable addresses”.

Yahoo Verification Notices

All valid emails will be marked as “ok”, all emails that do not exist will be marked as “fail”.
Some valid email addresses are disabled so during mail send you can get some bounces like this:

: host k.mx.mail.yahoo.com[98.139.54.60] said: 554
delivery error: dd Sorry your message to xxxxxxxxx@yahoo.com cannot be
delivered. This account has been disabled or discontinued [#102]. -
mta1240.mail.ac4.yahoo.com (in reply to end of DATA command)

Research over the long term does not give any solution for detecting disable emails without a mail send.
We check  other popular software and services and find that some of them do not verify yahoo at all or have the same problem.
