Why validate before you send
Lower bounce rates
Remove undeliverable addresses before you send, so your bounce rate stays under the threshold ESPs use to throttle or suspend senders.
Protect sender reputation
Hard bounces and spam-trap hits damage domain and IP reputation. Cleaning your list first keeps future sends landing in the inbox.
Stop paying to email dead addresses
Most ESPs bill by contact or send volume. Removing invalid and disposable addresses cuts wasted spend immediately.
Better campaign metrics
Open and click rates are calculated against your list size. A cleaner list means metrics that actually reflect engagement.
Verdicts you get for every address
| Verdict | Description |
|---|---|
| Valid | Deliverable, real inbox — safe to keep and send to |
| Invalid / undeliverable | Bad syntax, non-existent domain, or rejected mailbox |
| Disposable | Mailinator, Guerrilla Mail, and thousands of known temp-mail providers |
| Role account | info@, admin@, support@, sales@ — low-engagement, high-complaint addresses |
| Catch-all | Domain accepts all mail — can't confirm the specific mailbox exists |
| Typo | gmial.com, hotmial.com — with a suggested correction |
Typo correction
When Verifence detects a likely typo in a domain — such as gmial.com or hotmial.com — it returns a suggested correction alongside the verdict. Fix the address instead of losing the contact entirely.
Typical workflow
Most marketing and sales teams use the web interface — no integration required.
- 1 Export your list as a CSV — from your ESP, CRM, or a lead form export
- 2 Upload it to Verifence — up to 100,000 addresses per list via the web app
- 3 Get a verdict for every address: valid, invalid, disposable, role, catch-all, or typo
- 4 Download the results CSV and remove or fix flagged rows
- 5 Import the cleaned list back into your ESP and send with confidence
Limits
Up to 100,000 emails per list through the web app. The API accepts up to 500 emails per request — for larger volumes, split the list into multiple requests. Each email costs 1 credit, regardless of which method you use.
Free email validator
Every Verifence account starts on the Free plan, which includes 50 email validations a month at no cost — no credit card required. It's enough to test a small list or check addresses one-off before deciding whether to upgrade.
Validate 50 emails freePricing
Email validation draws from the same credit pool as every other Verifence check. 1 credit = 1 email.
