Switched from ZeroBounce because we were spending $650 a month on verification alone. VeriMails does the same job for under $100. Catch-all detection is actually better.

Email verification for everyone.

Clean prospect lists before outreach

Remove invalid, risky, or outdated emails so every sequence targets real buyers and protects sender reputation.

Prevent high-bounce campaigns

Verification prevents deliverability drops that can significantly impact results across all future sales emails.

Trust your CRM data

Regular verification ensures accurate prospect records, reducing wasted outreach and boosting team confidence.

Protect sender reputation

High bounce rates trigger spam filters. Verify your list before every campaign to maintain inbox placement.

Improve open rates

Clean lists mean your emails reach real inboxes. Higher deliverability directly translates to better engagement metrics.

Common questions

We connect directly to the recipient mail server via SMTP and check whether the mailbox exists — no guessing, no third-party data. For domains with catch-all configurations (which accept any address), we detect the catch-all and flag it clearly so you can decide how to handle those addresses.
Each result includes a Safe to Send flag. An address is marked safe when our verification confirms the mailbox exists and is deliverable. Invalid, disposable, catch-all, and unverifiable addresses are flagged as not safe. Use the safe_to_send field as your primary filter — no need to build complex logic around individual status codes.
VeriMails automatically adapts to each email provider for maximum accuracy. Every address goes through multiple verification layers. You get a clear valid/invalid result, or a confidence score when a definitive answer isn’t possible.
No. Credits never expire. Buy them when you need them and use them at your own pace — no subscriptions, no monthly minimums, no recurring charges.
Most single verifications complete in 1–3 seconds depending on the mail server’s response time. Bulk CSV jobs run verifications in parallel — a list of 10,000 emails typically finishes in 20–40 minutes.
CSV files with an email column header, or emails in the first column. All original columns are preserved in the output file alongside the verification results, so you can feed results directly back into your CRM.
Yes. Every new account receives 100 free credits — no credit card required. Credits are purchased in one-time packs starting at $19 for 10,000 verifications.
