How MailValid pricing works
One credit equals one verified email address. Credits never expire. Every plan starts free, no credit card required.
Simple credit-based pricing
You buy credits, each one covers a single definitive result – valid, invalid, or catch-all. Malformed addresses and duplicates within the same batch are never billed.
Credits carry over indefinitely
Unlike competitors who expire purchased credits 12 months after purchase, MailValid credits carry over indefinitely. A slow month never costs you money you've already spent.
Plans that scale with you
Start on Free with 100 credits, move to Starter ($15/month, 10,000 credits) or Growth ($50/month, 50,000 credits), or switch to Scale at a flat $0.75 per 1,000 emails for 100,000+ a month.
20% off on annual billing
Every paid plan – Starter, Growth, and Scale – gets 20% off on annual billing. Pay once a year and save 20%, which brings Scale as low as $0.60 per 1,000 emails.
| Starting price | Free — 100 credits, no credit card required |
| Paid plans from | $15/month (Starter) or $12.00/month billed annually — save 20% |
| Do credits expire? | Never — not on Free, not on paid plans, not on pay-as-you-go top-ups |
| Annual billing | 20% off on every paid plan — billed once a year |
| High-volume pricing (Scale) | Flat $0.75 per 1,000 emails from 100,000 to 1,000,000+ credits/month, or $0.60 on annual billing — no tier-hopping |
| Cost per 1,000 emails | $1.50 → $1.00 → $0.75 monthly, or as low as $0.60 on annual Scale billing |
Why non-expiring credits matter
Industry benchmarks put annual list decay at 20–30%. Here's how MailValid handles it differently.
Other providers
- Credits expire after 12 months
- You pay twice: once for the original check, again when you re-verify
- Unused credits are lost when they expire
- Monthly plans reset – use it or lose it
MailValid
- Credits never expire, ever
- Carry over from any plan type – monthly, annual, or pay-as-you-go
- No pressure to use credits before a deadline
- Re-verify decayed lists without buying credits again
Email lists naturally decay as people change jobs and abandon addresses — industry deliverability benchmarks commonly put annual list decay in the 20–30% range. Several competitors reinforce this by expiring unused credits after a fixed window (NeverBounce, for example, expires purchased credits 12 months after purchase), which effectively charges you twice: once for the original check, and again when you have to re-verify because your credits ran out. MailValid credits don't expire, whether they came from a monthly plan, an annual plan, or a pay-as-you-go top-up.
Cost per 1,000 emails, compared
Email verification pricing is usually quoted per credit, but the number that actually matters when comparing providers is cost per 1,000 emails verified. Below is MailValid's rate against publicly listed pricing for the providers people compare us to most, as of July 2026.

Email verification terms, explained
- Email verification credit
- 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.
- Catch-all domain
- A mail server configured to accept all messages regardless of the mailbox name, making it impossible to confirm a specific address exists. MailValid flags these as a distinct risk category rather than a hard bounce.
- 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 from the Growth plan up.
- Hard bounce vs. soft bounce
- A hard bounce means the address is permanently undeliverable (doesn't exist); a soft bounce is temporary (mailbox full, server down). Verification before sending prevents almost all hard bounces.
Frequently asked questions
Do email verification credits expire?
No. MailValid credits never expire, whether purchased on a monthly plan, an annual plan, or as a pay-as-you-go top-up. Unused credits simply roll over to the next month.
How much does email verification cost per 1,000 emails?
On MailValid, cost per 1,000 verifications on monthly billing is $1.50 on Starter, $1.00 on Growth, and a flat $0.75 on the 100K+ Scale tier regardless of how much volume you commit to. Annual billing takes 20% off each: $1.20, $0.80, and $0.60 per 1,000.
What's the cheapest email verification API?
Price per credit varies by provider and volume. At 100,000 emails, publicly listed rates range from $75 (MailValid's Scale tier) 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's Growth plan ($50) costs about 4.5x less than ZeroBounce's pay-as-you-go rate ($225) and 8x less than 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.
How does annual billing work for MailValid?
Annual plans are billed once, upfront, at a 20% discount versus paying monthly, and unlock a full 12 months of access and credits. This applies to the Starter, Growth, and Scale plans; credits never expire.
What happens if I go over my plan's credits?
You won't be cut off mid-verification. Once you use your monthly allotment, top up instantly with pay-as-you-go credits (from 1,500 credits for $5) or move up a 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, Starter 50/min, Growth 100/min, and the 100K+ Scale tier 200/min. Bulk jobs allow up to 100 / 2,000 / 5,000 / 10,000 emails per job (Free / Starter / Growth / Scale) — 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, from the Growth plan up. MailValid flags disposable domains and catch-all addresses so you can filter out low-quality or fraudulent signups before they reach your database.
