john@gmial.com Will Never Reach Your CRM
Someone types a typo into your form. The Email Validator catches it, checks the domain, and flags the record before it becomes a bounced campaign three months later.
You've been here before
Email Marketer
Your bounce rate is climbing because form submissions include typos, fake addresses, and disposable email domains. Every bad email costs deliverability score.
Sales Manager
Reps spend time following up on leads with invalid emails. Half the discovery calls never happen because the email bounced.
Nonprofit Coordinator
Donation receipts bounce because donors mistyped their email. You can't send tax acknowledgments to addresses that don't exist.
One tool, four superpowers
Format validation
Catches formatting errors: missing @, double dots, spaces, and other structural problems. Fast and instant.
MX record check
Verifies the email domain exists and has valid MX records. Catches typos like gmial.com and outloo.com.
Disposable detection
Identifies temporary email services (Guerrilla Mail, Mailinator, etc.) used to bypass signup requirements.
Typo correction
Suggests corrections for common domain typos. 'gmial.com' gets flagged with a suggestion of 'gmail.com'.

Frequently asked questions
Does it actually send an email to verify?
No. It checks the mail server without delivering anything. The recipient never knows their address was validated.
Can it catch typos in common domains?
Yes. It suggests corrections for known typo domains: gmial.com to gmail.com, yaho.com to yahoo.com, outloo.com to outlook.com.
What about catch-all domains?
Some domains accept all addresses (catch-all). The validator flags these so you know the domain is valid but the specific mailbox can't be confirmed.
Does validation slow down form submission?
Syntax and domain checks take milliseconds. Full deliverability checks take 1-2 seconds. The submitter doesn't wait because validation happens after submission.
