What MailGuard catches
Works on every funnel builder — paste one script tag
Every fake email that gets through your funnel is a setter call that goes nowhere, a follow-up sequence that bounces, and ad spend that evaporated.
Your email platform charges you per contact — including the fake ones. Your deliverability tanks when hard bounces pile up. And your team slowly stops trusting the leads.
MailGuard catches the bad emails at the source — the form — before they ever touch your CRM.
Typical funnel email breakdown
Only half your leads are worth calling. MailGuard fixes that ratio.
12 layers of verification — from instant disposable detection to live SMTP mailbox confirmation. No other tool runs this many checks.
170,000+ throwaway domains blocked instantly. Mailinator, Guerrilla Mail, YOPmail — caught before submit.
Connects to the actual mail server and confirms the inbox exists. Retries through greylisting automatically.
Static map + Levenshtein distance catches gmial.com, outlok.com, and anything novel — and suggests the fix.
Resolves all MX records in priority order. If the primary mail server is down, we try the next one — not give up.
Sends a random fake address to detect servers that accept everything. Flags them risky so you know to call first.
Checks if the email has a Gravatar photo — a strong signal the address belongs to a real, active person.
Optionally block Gmail, Yahoo, Hotmail and 200+ free providers. Keep only business emails in B2B funnels.
Your sending domain checked against 57 DNS blacklists daily. Instant email alert if you're ever listed.
Full domain check: DMARC policy, SPF, DKIM, MTA-STS, BIMI, reverse DNS. Graded A–F, re-checked daily.
Upload up to 100,000 emails as a CSV. Verified in the background, download clean and invalid lists separately.
One script tag, any platform. Auto-attaches to every email input on the page — Webflow, WordPress, Wix, anything.
Daily breakdown: valid, invalid, disposable, risky per widget. See which funnels have the dirtiest leads.
Seven checks fire in sequence — the whole thing takes under 200ms.
