The best ZeroBounce alternative
at 1/5th the price

The price gap is real

ZeroBounce charges $15 per 1,000 verifications. MailsGuard charges $3. If you verify 100,000 emails per year, that's $1,200 vs $300 — a $900 difference for identical results.

Credits that never expire

ZeroBounce expires unused credits after 12 months. MailsGuard credits never expire. Buy once, use whenever — no pressure to burn through your balance.

No lock-in

No monthly subscription required. Pay as you go, upgrade when you need more volume, cancel anytime. Your data is always yours.

Same technical depth

SMTP probe, MX lookup, syntax validation, disposable detection, catch-all flagging, role-based detection. Full JSON response with confidence score on every check.

Stronger privacy by design

MailsGuard never stores the email addresses you verify. We store only a cryptographic fingerprint (HMAC-SHA256) — mathematically impossible to reverse. ZeroBounce stores your emails for up to 30 days. We never do.

Webhooks included

Get notified instantly when a bulk job completes via webhook. Integrate directly with your CRM, Zapier, or custom workflows without polling our API.
