How it works
Batch or Real-time verification
Our service can be used to upload bulk lists of email addresses, or as a web service for real-time checking.
A simple process for you
We've done the hard work for you. All you need to do is upload your email list and wait for the results to come in. We support batch files in CSV or TXT formats.
See some screenshots of the self-service dashboard for batch verification.
What do we check?
We do complete email verification including :-- Syntax - a simple check to ensure the email address conforms to RFC 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).
- We never send an email during our checks.
Unrivalled expertise
Over 2 years development time has gone into our application to ensure that we can deliver the most reliable email verification on the planet. We have tailored the system to cope with the many vagaries of mail servers including grey-listing, false positives and velocity blocks.
To perform reliable email checking at the volumes we deliver is a very challenging task requiring detailed knowledge of ISP behaviour and mail server technology. No other email verification service can match the accuracy of our checks.
Fast checking
We can check at rates over 100,000 emails per hour.
Reliable and secure
Security of your data is our primary concern. To ensure security, we implement:
- Robust data security implemented using Microsoft Trustworthy Computing guidelines.
- Logical security of your data by allocation of your own, dedicated database. Any data that you upload goes into your database and is not visible by anyone else.
- Physical security in secure US and UK data centers.
- Once you delete a list from our system, it is wiped completely off our servers.
Ultimately, no one gets access to your data except you.
As well as the assurance of security, we appreciate that you want reliability. That’s why, as a customer, you receive priority support by phone and email. In the unlikely event of a technical problem, our promise to you is to resolve your issue within 24 hours.
Our systems include built in exception and error alerting. This means that, in the unlikely event that you need to call us, we’ll already know about the problem and be well on the way to fixing it.
