Instantly verification cost calculator: what checking your leads costs in credits

Instantly's Data Credit System article and its How to Verify Leads guide both say lead verification costs 0.25 credits per lead. Its catch-all article gives the same 0.25 credits per lead for catch-all verification; it does not say whether that is charged on top of the standard check, so the calculator counts 0.25 once.

Credits are bought as monthly credit plans, from Nano ($9 for 150 credits) to Hyper 6 ($1,700 for 200,000 credits). So a verification costs $15 per 1,000 on Nano, $7.83 on Growth, $4.93 on Hyper and $2.13 on Hyper 6. Paying annually is 10% less, with all credits upfront. Instantly's own benchmark post (31 Jan 2026) puts it at "~$8-16" per 1,000.

The same credits pay for SuperSearch lead data, so credits spent verifying are credits you cannot spend finding leads. The calculator shows what share of your plan verification takes.

Yes. Instantly's credit article says credits "expire 2 months after purchase if unused" on monthly plans and 1 year after purchase on annual plans (read 30 Oct 2026). If your lead volume swings from month to month, a quiet month's credits can expire before you use them.

SimpleVerifier's Starter ($9, 2,500 emails a month) and Growth ($19, 10,000 emails a month) allowances reset every month and do not roll over either. Pro ($29.99 a month) has no allowance to expire: 100,000 a month run at full speed, then big lists run slower, never cut off.

At 10,000 leads a month, verification uses 2,500 credits: $49.25 of credits on Hyper, or Supersonic ($97 a month) if you bought credits only for it. SimpleVerifier Growth covers 10,000 a month for $19 ($1.90 per 1,000).

At 50,000 leads a month it is 12,500 credits: $246.25 at Hyper's rate, more than the plan's 10,000 credits, or Hyper 2 at $300 a month. SimpleVerifier Pro is $29.99 a month for that volume.

Connect Instantly on the connect page with an Instantly API v2 key, pick a campaign or lead list, and turn on daily auto-verify (paid plans). Once a day SimpleVerifier pulls that campaign's leads and checks only the addresses it has not seen there before, up to 10,000 a day per campaign. By default it tags each lead with sv_status (valid, risky or invalid) in Instantly; removing invalid leads or adding them to your block list is opt-in. The Instantly integration page lists every API call it makes.

Checks are not instant. List jobs average about 30 rows a minute over a day (up to about 60 while the day's capacity lasts), shared by all customers, so a large batch of new leads can take most of a day. Catch-all addresses are always marked risky, never valid, because no SMTP check can confirm a mailbox on a domain that accepts every address.

When you verify a small number of leads and already have spare credits. If your plan's credits would otherwise expire unused, verification inside Instantly costs you nothing extra, and a separate tool adds a step for no saving.

When speed matters more than price. Instantly verifies at upload and in the campaign's Leads tab, and its catch-all article says it attempts to resolve catch-all addresses, which we do not: we mark them risky and leave the decision to you. If you want an answer on catch-all leads inside Instantly, try its check on a sample.

A separate verifier pays off when the volume is large, when credits keep expiring or run short for lead finding, or when the same leads also go to a CRM, a Clay table or another sequencer and you want one result format everywhere.
