Email Validation Service
Email validation and verification that reduces bounce rates
Overview
Improve accuracy and ensure the validity of every email address in your database. Our software instantly matches addresses against known dead domains, malicious addresses and common typing errors.
Our six-step cleaning & validation process

Keyword scrub
We remove addresses containing words like spam, junk and abuse.

Bounce file compare
We compare against 19.5 million known bounces — including challenge-response and removal requests — and remove matches.
- 03
Complainers file
We remove matches from our complainers file, plus SpamCop members (we hold about 75% of the SpamCop database).
- 04
Domain screening
We remove spam-seed, bot, blacklisted and bogus domains using a list of 156,000+ domains we own and maintain.
- 05
Mailbox validation

Frequently asked questions
How fast is validation?
Most files are processed within 24–48 hours depending on size. Urgent turnaround is available on request.
What is a “risky” address?
Catch-all domains, role accounts (such as info@ or sales@) and addresses with a poor history. We flag them separately so you can decide whether to mail them.
Do you send emails to my contacts during validation?
No. Validation checks domains, mail servers and our suppression files without sending any message to your contacts.
