Why it matters

Why email verification matters

Every bounced email tells mailbox providers your list is poorly kept. Too many bounces and even your good emails start landing in spam, or your sending account gets paused.

Protect your sender reputation

Low bounce rates keep your domain trusted by Gmail, Outlook and others.

Reach real inboxes

Messages go to people who can actually read them.

Cleaner reporting

Open and reply rates reflect real recipients.

Save money

Stop paying your email platform for dead addresses.

How it works

Our email verification process

From a raw list to addresses you can send to with confidence.

  1. Upload your list

    Send a CSV or Excel file, or give us CRM access.

  2. Clean

    We fix formats, remove duplicates and catch common typos.

  3. Verify

    Each address is checked, and our researchers review the uncertain ones.

  4. Classify

    Every address is marked valid, risky or invalid, with the reason.

  5. Replace and deliver

    You get the results back, with current replacements for contacts who have left if you ask.

What you get

Get in touch
What is email verification?
Email verification checks whether an email address is real and able to receive mail, so you can remove bad addresses before you send.
What do valid, risky and invalid mean?
Valid addresses are safe to send to. Invalid addresses will bounce and should be removed. Risky addresses, such as accept-all domains or shared inboxes, may or may not reach a person, so send to them with care.
Do you send emails to check the addresses?
No. Verification does not send any email to the people on your list.
Can I verify a single address or a small list myself?
Yes. Use Domailfix, our self-serve tool, to check one address or a list at any time.
What is a good email bounce rate?
Aim to keep your bounce rate under 2%. Verifying lists before every large send is the simplest way to stay there.
