What actually makes an email verification API expensive
Most email verification pricing is expensive for reasons that have nothing to do with the check itself. You pay for a monthly seat you use twice, a minimum plan that bundles 50,000 credits when you needed 3,000, or credits that quietly expire at the end of the billing cycle so last month's unused balance is simply gone. The per-check cost is often the small part; the packaging is where the money leaks.
Verifly is priced to remove that packaging. It is pay-as-you-go from $2 per 1,000 checks, dropping to $0.60 per 1,000 at volume, and the credits never expire. There is no seat, no monthly minimum, and no plan to "right-size." If you verify 500 addresses this month and 90,000 next month, you pay for exactly 90,500 checks and nothing else.
Cheap does not mean a lighter check. Every address still goes through a live SMTP mailbox probe and comes back with the same deliverable / undeliverable / risky verdict and disposable, role, and catch-all flags that the higher-priced tools charge a subscription for.
Estimate your real cost before you commit
- Count the addresses you actually verify in a typical month — not the plan size a vendor wants to sell you.
- Multiply by the tier rate: roughly $2 per 1,000 at the entry level, sliding toward $0.60 per 1,000 as monthly volume climbs.
- Register for 100 free credits at verifly.email/api/v1/autonomous/register and verify a real sample to confirm the results fit your needs.
- Buy credits only when you have work to do — because they never expire, there is no penalty for topping up in advance or letting a balance sit.

Frequently asked questions
What is the cheapest way to verify emails with Verifly?
Pay-as-you-go credits starting at $2 per 1,000 checks, falling to $0.60 per 1,000 at higher volume. Because there is no subscription, the cheapest option is simply to buy only what you need.
Do the credits expire?
No. Verifly credits never expire, so you never lose a balance at the end of a billing cycle the way you do with monthly plans that reset unused credits.
Is there a monthly fee or minimum?
There is no monthly fee, no seat cost, and no minimum spend. You can verify a few hundred addresses one month and nothing the next without paying to keep an account open.
Is a cheaper API a less accurate check?
No. Every address gets a live SMTP mailbox check with disposable, role, and catch-all detection. The low price comes from removing subscription packaging, not from skipping verification steps.
How do I try it before paying?
Self-register at verifly.email/api/v1/autonomous/register for 100 free credits — no card and no captcha — and verify a real sample of your own list.
Does the price drop as I verify more?
Yes. The per-thousand rate slides down with volume, so larger cleanups cost less per address than small ad hoc checks.
