Introducing the Email Validator — Clean Your List in Seconds

Invalid and mistyped email addresses quietly damage your sender reputation — every bounce tells mailbox providers your list is low quality. The new Email Validator helps you catch those problems before you import or send, right in your browser.

What it does

• Format checking: RFC 5322-style validation with a specific reason for every rejection.
• Typo detection: spots near-misses like gmial.com and suggests gmail.com with one-click fixes.
• Bulk paste: validate hundreds of addresses across new lines, commas, or semicolons.
• Duplicate detection: case-insensitive, so A@x.com and a@x.com are caught.
• Export: copy the valid list or download a full CSV report.

Why it matters

Bounce rate is one of the metrics mailbox providers watch most closely. Every invalid address you remove before sending is a bounce that never happens — which protects inbox placement for your whole list, not just the bad addresses.
