Verify any email address in your browser. This free email checker validates syntax, catches domain typos with a “did you mean?” fix, and flags disposable and role-based addresses — so you can check if an email is valid before you send. No signup, no data leaves your device.
Every check runs instantly and deterministically in your browser. Together they catch the list-quality problems behind most bounces and spam complaints — before you ever hit send.
Confirms a valid local part, a single @, and a real domain with a 2+ character TLD using RFC-style rules. Malformed addresses can never receive mail.
Catches near-miss domains like gmial.com, gmai.com, hotmial.com, or outlok.com and suggests the correct spelling with one-click apply.
Flags throwaway and temporary providers (Mailinator, Guerrilla Mail, 10MinuteMail, YOPmail, TrashMail and dozens more) that never read your mail.
Identifies shared inboxes like info@, support@, sales@, admin@, and noreply@ that draw more complaints and rarely convert.
Classifies the domain as a free consumer provider (Gmail, Outlook, Yahoo, iCloud, AOL, Proton) or a custom business domain.
A browser can't safely query MX records or perform an SMTP handshake. Real mailbox verification runs server-side — IGSendMail does it automatically for your whole list.
Mailbox providers like Gmail and Outlook score every sender on bounce rate, spam complaints, and engagement. Sending to invalid, disposable, or role-based addresses tanks all three signals at once. Verifying first keeps your reputation high so your real subscribers keep landing in the inbox.
A bounce rate above roughly 2% gets you throttled or blocked. Catching typos (gmial.com), throwaway mailboxes, and malformed addresses before you send keeps your hard-bounce rate low and your list deliverable.
Most email platforms bill by contacts or sends. Pruning dead, fake, and risky addresses means you stop paying to email people who'll never open — and your engagement metrics actually reflect real humans.
For confirmed MX records and live mailbox checks across an entire list, IGSendMail includes bulk verification right inside the app — no exporting or third-party tools.
IGSendMail combines built-in bulk email verification (real MX + SMTP) with 99% inbox delivery, automatic authentication, and bounce management — so clean lists actually land.
