How the price compares
Email validation APIs charge per email: MailboxValidator $29.95 for 3,000, Emailable $38 for 5,000, ZeroBounce $39 minimum for 2,000 (rival median about $10 per 1,000, checked 27 Sep 2026). Those also probe the mailbox by SMTP; Mailvett checks syntax, MX, disposable, role, typos, SPF and DMARC without touching the mailbox, so it is priced below them: Cleaner $19/month for 5,000 calls of up to 10 emails, or $5 pay-as-you-go for 1,000 calls that never expire.

Questions
How do I get it after paying?

Can I get a refund?
Yes. If it doesn't work as described, email us within 14 days and we fix it or refund you in full. See the refund policy.
Is checkout secure?
Card details go only to Stripe. CyberMax never sees them; sales tax or VAT is calculated at checkout.

Any time, from the link in your receipt email. You keep access until the end of the paid period.
Can I try before buying?
Yes: the free tier gives 50 calls a day with no key and no signup.
Can AI agents use it?
Yes. The same key works on the REST API and the remote MCP server at https://mailvett.cybermax-tools.workers.dev/mcp.
