MailVet vs ZeroBounce
ZeroBounce checks mailboxes and MailVet doesn't. If you need to know a specific address exists, pick ZeroBounce.
The facts
| Fact | ZeroBounce | MailVet |
|---|---|---|
| Mailbox check over SMTP | Yes. mailbox_not_found marks addresses that don't exist. | No. MailVet never contacts the mailbox, so it can't tell you one exists. |
| Catch-all detection | Yes, catchall_domain. | No. That takes an SMTP probe. |
| Disposable domains | Yes, a disposable sub-status. | Yes, from open lists refreshed daily. Domains not on them yet can get a suspect signal, with partial coverage. |
| Role addresses | Yes, a role_based sub-status. | Yes, role. |
| Typo suggestions | Yes, did_you_mean. | Yes, did_you_mean, for typos of big providers. |
| Mail server (MX) check | Yes, mx_found and mx_record. | Yes, mx and accepts_mail. |
| Your own allow and block rules | Yes, by email, domain, MX record or TLD. | Yes, by domain. 10 rules on Free, up to 10,000 on Scale. |
| Many addresses at once | A batch endpoint, plus file uploads for more than 200 at a time. | 100 per API request. Up to 10,000 rows in the dashboard's CSV cleaner. |
| Free to start | 100 validation credits a month. Their page ties this to signing up with a business or premium domain. | 100 checks a month, no card. |
| Price | Pay as you go from $39 for 2,000 credits. Subscription from $99 a month, minimum 10,000 credits. | $19 a month for 5,000 checks, up to $99 for 100,000. |
| Unused credits or checks | Subscription credits roll over. Without a subscription, expiry rules may apply. | Don't carry over. The quota resets on the 1st, UTC. |
| Addresses stored | Not compared. Read their privacy policy. | No. Our app doesn't store or log addresses, only the domains it has seen. Send them by POST to keep them out of URLs and host logs. |
