What our customers say
"MailValid’s MCP Server Makes Email Verification Fast and Effortless. MailValid provides an MCP server, so I can plug it directly into Claude and get things done super fast. There’s no need to use an API or do everything through the UI."

Vipin J.
Software Developer
"I use MailValid as a pre-send verification step in a cold email pipeline (single-email API calls, low volume). The API is simple to integrate, and it reliably catches invalid, disposable, and syntax/MX failures. The status_reason field (e.g., role-based) is genuinely useful — I allow role addresses by policy, and the granularity makes it a one-line decision rather than guesswork."

"Lightning-fast email verification in under 500ms. Email verification takes less than 500ms. We use it to verify candidate lists and clean our ATS before outreach. Removing invalid emails meant more of our outreach actually reached people."

"MailValid delivers fast responses and flexible, non-expiring credits. MailValid has a really quick response time. Even after I cancelled my subscription, the email verification credits did not expire. MailValid is very affordable. The email verification results are value for money and accurate."

Resets monthly
MailValid rates above are MailValid Plus monthly prices — pay-as-you-go packs match the same per-credit scale with no subscription. Competitor pricing sourced from each provider's public pricing page (or the current third-party pricing tracker where a vendor's page renders pricing dynamically), as of July 2026. Hunter.io bundles verification with lead-finding credits (~$0.006–0.0075 per verification if a plan's credits are spent entirely on verification).
Account required
Sign up free or log in to buy credits. New accounts start with 100 free credits, no card required.
One credit is consumed for each address MailValid returns a definitive result for (valid, invalid, or catch-all). Credits don't expire and carry over month to month.
Cost of a thousand
The price to verify 1,000 email addresses. It puts providers that charge per credit, per pack or per month on the same footing, and it's the number used throughout this page.
Disposable email address
A temporary address from a service like Mailinator or Guerrilla Mail, typically used to bypass a signup form once. These are detected and flagged on every plan.
Pay-as-you-go, not forever
Buy credits only when you need verification — there's no subscription to keep paying. Packs are one-time and the credits never expire.
Frequently asked questions
Do email verification credits expire?
No. MailValid credits never expire, whether they came from a MailValid Plus plan, a pay-as-you-go pack, or a top-up. Unused credits simply roll over to the next month.
How much does email verification cost per 1,000 emails?
On MailValid Plus the cost per 1,000 verifications falls as your plan grows — from about $2.90 per 1,000 on the 10,000-credit plan down to roughly $0.80 per 1,000 on the 1,000,000-credit plan. Pay-as-you-go packs follow the same scale.
What's the cheapest email verification API?
Price per credit varies by provider and volume. At 100,000 emails, publicly listed rates range from $129 (MailValid Plus) to $800 (NeverBounce) — see the comparison table above for the full breakdown across ten providers.
Is MailValid cheaper than ZeroBounce or NeverBounce?
At 50,000 emails, MailValid Plus ($79/month) costs far less than ZeroBounce's pay-as-you-go rate ($225) and NeverBounce ($400) for the same volume, based on each provider's published rates as of July 2026. Unlike NeverBounce, whose credits expire 12 months after purchase, MailValid credits never expire.
Is there a free email verification tool?
Yes. MailValid's Free plan includes 100 credits with no credit card required, covering single and bulk verification (up to 100 emails per batch) before you commit to a paid plan.
Can I buy credits without a subscription?
Yes. Pay-as-you-go lets you buy one-time credit packs — from 2,000 credits for $8 up to 1,000,000 for $899 — with no subscription and no auto-renew. Credits never expire, so you can top up whenever you need to.
What happens if I go over my plan's credits?
You won't be cut off mid-verification. On MailValid Plus you can top up instantly with a one-time credit pack (from 5,000 credits for $19) or switch to a bigger plan — unused credits roll over and never expire either way.
Are all email verifications charged?
No. MailValid only deducts credits when an email verification returns one of these final, actionable results:
valid
invalid
catch_all
do_not_mail
If an email verification returns “unknown”, no credits are deducted.
Unknown results are automatically skipped during both single email verification and bulk email verification, ensuring you only pay for verifications that produce a usable result.
What API rate limits apply to each plan?
Free allows 10 requests/min and up to 100 emails per bulk job. Every paid plan — MailValid Plus and pay-as-you-go — gets 200 requests/min and up to 10,000 emails per bulk job. Contact support if your integration needs a higher ceiling.
What is email verification?
Email verification is the process of checking whether an email address is correctly formatted, exists, and can receive mail, without sending an actual message. It flags invalid, disposable, and risky addresses before they cause bounces.
What's the difference between email verification and email validation?
The terms are used interchangeably in most of the industry. Both describe confirming an address is deliverable — checking syntax, domain and MX records, and mailbox existence — before you send to it.
Does verifying my email list actually reduce bounce rates?
Yes. Removing invalid, disposable, and catch-all-risk addresses before sending is the most direct way to lower hard bounces, which protects your sender reputation and inbox placement over time.
Do unused credits roll over to the next month?
Yes. Because MailValid credits never expire, any credits you don't use in a given month carry forward automatically — you never lose what you've already paid for.
Can I verify emails in real time via API, not just in bulk?
Yes. The MailValid API returns a verdict on a single address in under 500ms, so you can validate emails at the point of signup or entry, in addition to bulk list uploads.
Does MailValid detect disposable or fake email addresses?
Yes, on every plan. MailValid flags disposable domains and catch-all addresses so you can filter out low-quality or fraudulent signups before they reach your database.
Ready to stop paying for bounces?
Start free with 100 credits, or scale at any tier with MailValid Plus or pay-as-you-go.
