Every tool in this category sells credits, and every pricing page quotes a credit count as if it were a contact count. It is not, and the gap is not small.
The arithmetic the pricing page skips
Snov.io states the rule plainly on its own pricing page: each prospect found, each email verified, and each company profile viewed costs one credit.
Read that again with a workflow in mind. You find an address, that is one credit. You verify it before sending, because sending to an unverified list is how domains get burned, and that is a second credit. The same contact has now cost two.
So the Starter plan at $39 a month with 1,000 credits is 500 verified contacts, not 1,000. Pro S at $99 with 5,000 credits is 2,500. Annual billing takes 25% off the price, and nothing off the arithmetic.
Nobody is hiding this. It is stated on the page. It just is not applied, and the number people budget against is the one in the big type.
Where the credits actually go
| Action | Credits | What you get |
|---|---|---|
| Find a prospect | 1 | An address, unverified |
| Verify an email | 1 | Confidence it will not bounce |
| View a company profile | 1 | Context for the message |
A researched contact, meaning found, verified, and with the company looked at, is three credits. At 1,000 credits that is 333 contacts a month.
Whether you need all three depends on what you send. A templated sequence to a scraped list uses one. Anything personalised enough to be worth sending usually uses all three.
What verification is actually for
Skipping the verify step looks like a way to double your plan. It is the single most expensive saving available in cold email.
Bounces are what mailbox providers use to decide whether your domain is worth delivering. A list with a meaningful bounce rate does not just fail on the bad addresses; it degrades delivery for the good ones, and the damage outlives the campaign. Warming a domain back up takes longer than it took to burn.
That is why the second credit is not optional overhead. It is the credit that makes the first one worth spending.
Plans against real volume
Three renders per published video is the multiplier in AI video. Here it is two to three credits per usable contact. Same shape of mistake, different market.
| You want per month | Credits at 2/contact | Credits at 3/contact | Cheapest plan that fits |
|---|---|---|---|
| 300 contacts | 600 | 900 | Starter, $39 |
| 500 contacts | 1,000 | 1,500 | Starter at 2, Pro S at 3 |
| 2,000 contacts | 4,000 | 6,000 | Pro S at 2, Pro M at 3 |
The jump from Starter to Pro S is $39 to $99. That step happens sooner than the credit numbers suggest, and it happens because of verification rather than volume.
The free question
There is no permanently free tier. Snov.io runs a 7-day trial with restrictions, and premium features like the API and integrations are not part of it.
That matters if you are searching for "email finder free" expecting a standing allowance. What exists is a window to evaluate. Plan to decide inside it rather than to work inside it.
What to check before you pick any of these
The credit rule is the thing to read first on any tool in this category, not the headline allowance. Three questions settle it:
Does verification cost a credit, or is it included? Some tools bundle it, which changes the effective price more than a 25% annual discount does.
Do unused credits roll over, or reset monthly? A plan sized for your peak month is expensive if the quiet months evaporate.
Is there a bulk verification path for a list you already own? Importing 5,000 existing addresses to clean them is a different job from finding new ones, and it is priced out of the same pool.
Where this fits
If you are running cold outreach at any real volume, budget two to three credits per contact and size the plan from that, not from the number on the pricing page. The tier you actually need is usually one above the one the marketing implies.
Snov.io publishes its credit rule openly, which is more than several competitors do, and the lifetime-value question is whether verification being metered separately suits your workflow or fights it.
For the same arithmetic applied to a different market, the AI video cost calculator does this for video plans, where the hidden multiplier is re-takes rather than verification.
