FAQs – General

Put simply, email verification is designed to remove bad (invalid) email addresses from your lists. Invalid email addresses turn into “hard bounces” when you send an email campaign.

Hard bounces are email addresses that could not be delivered, for example due to an invalid mailbox. They are treated very seriously by most email service providers such as MailChimp, Constant Contact, Get Response etc.

Most people come to us because their email service provider (ESP) has warned them about hard bounces. These are a real problem for your ESP and can get their servers blocked by some of the major ISPs such as Yahoo.  If your list contains more than a handful of invalid emails your ESP will ask you to verify the list before uploading into your account, or if not they may suspend your account.  If you run your own mail servers you will end up getting your IP addresses blacklisted by the major ISPs if you send more than a tiny percentage of invalid email addresses.

We do complete email verification including :-
Syntax – a simple check to ensure the email address conforms to common standards.
Domain – a lookup on the domain element of the email address to ensure it is configured to accept emails.
User – the really clever bit, where we check that the user mailbox exists (otherwise known as a SMTP check).

A hosted service. This is the only way we can offer the unrivalled coverage and accuracy that we do. All verifications are run from our global data centres using our huge network footprint.
