What gets checked
More than a basic email syntax test.
A valid-looking address can still be risky. VeryFire combines address, domain, mailbox, and list-quality signals so you can decide whether an address belongs in your workflow.
Syntax and domain format
Mailbox and MX deliverability signals
Common email typo correction
Disposable, masked, and automated services
Role inboxes such as info@ or support@
When to use it
Fast checks for small decisions.
The free checker is for quick, single-address decisions. For large files, automated signup protection, or product integrations, use CSV validation, AI forms, or the API.
While reviewing signups
Confirm typo-prone domains like gmial.com or hotmial.com before you accept the contact.
Before importing contacts
Spot-check samples from a list before moving into CSV cleanup or API validation.
