Verification credits vs monthly plan: which costs less for your volume?
In short: Enter the price and size of a pack of credits, the price and allowance of a monthly plan, and how many checks you need each month. You get both costs, the break-even volume and a table at lower and higher volumes. Every price is one you type. Limit: It compares two options at the prices you enter; it does not know whether either price is current.
Enter what a pack of verification credits costs and how many checks it holds, what a monthly plan costs and how many checks it covers, and how many checks you need each month. The calculator gives both costs, the volume at which they cost the same, and a table for half and double your volume. It includes no vendor prices; all numbers are yours.

|---|---|---|---|---|
| 3,750 | $18.75 | $39.00 | Credits | $225.00 |
| 7,500 | $37.50 | $39.00 | Credits | $450.00 |

| 60,000 | $300.00 | Over its allowance | Credits (plan too small) | $3,600.00 |
Formula: credits cost = checks x (pack price / pack checks). The plan costs its monthly price up to its allowance, plus your extra-check price beyond it if you entered one. Credits that expire, taxes and discounts are not included.
Sample result
With the example numbers, credits cost $75 for 15,000 checks and the plan $39; the two are equal at 7,800 checks a month.

The cheaper option is the one that fits your volume.
- Count the addresses you verify in a typical month, and enter that as the checks you need.
- Upload or paste it at /verify. Every address gets a live mailbox check, and the first 100 email checks are free with a Google sign-in, no card.
How do I compare credits with a monthly plan?
- Open the two pricing pages you are comparing and note the price of a credit pack, how many checks it holds, the monthly plan's price and its monthly allowance.
- Enter them, plus the price per extra check if the plan has one, and how many checks you need a month. The pre-filled numbers are examples.
- Read the break-even volume and the cost of each option at your volume.
- Look at the table for the volumes either side of yours, and the 12-month cost of the cheaper option.
Example
- You enter
- A pack of 10,000 checks for $50 and a monthly plan of $39 covering 20,000 checks, with 15,000 checks needed a month. These are example numbers.
- You get
- Credits cost $0.005 a check, so 15,000 checks cost $75 against $39 on the plan. The two cost the same at 7,800 checks a month: below that the credits cost less, above it the plan does.
- Limits
- Runs in your browser. Every price is the one you enter.
How is the break-even worked out?
Credits cost the pack price divided by the checks in the pack, per check. A monthly plan costs its price whether you use all of its allowance or not. The two cost the same at the volume where the credits' per-check cost times the checks equals the plan price: plan price divided by the cost per check. Below it the credits cost less; above it, up to the plan's allowance, the plan costs less. If that volume is more than the plan covers, the credits are cheaper for every volume the plan can cover.
What does the calculator leave out?
Credits that expire, credits that roll over, taxes, discounts for annual billing, minimum purchases and the speed or limits of a plan are not in the arithmetic, and neither is whether the results are any good. Add those yourself if they matter. Read what credits are and how they are spent and annual against monthly plans for what to check on a pricing page.
Does my volume stay the same each month?
Cold email lists come in bursts, so a month with a large list and a quiet month are different cases. The table prices a quarter, half, double and four times your volume, so you can see where each option wins. Repeat checks on the same list cost again with credits, which is why how often to verify a list changes the number you should enter.
Who uses this tool, and for what?
- Cold email senders
- Decide between topping up credits each campaign and a monthly plan.
- Agencies
- Work out which model suits a client whose volume changes every month.
- Founders
- Check whether a first list justifies a plan or a single pack.
What can’t this tool tell you?
- It compares two options at the prices you enter; it does not know whether either price is current.
- It leaves out expiry, rollover, taxes and annual discounts.
- It assumes the same volume every month when it gives the 12-month cost.
- It says nothing about the quality or speed of the verification itself.
Common questions
- Does it know any vendor's prices?
- No. Every number comes from you, so it works for any provider and is never out of date.
- What if the plan has no price for extra checks?
- Leave the field empty. Volumes over the plan's allowance are shown as over the allowance, and credits are marked as the option that fits.
- Why does the table show different volumes?
- Your month may be quieter or busier than the number you typed. The table shows a quarter, half, double and four times it.
- Does it include tax or annual discounts?
- No. Enter prices after any discount you will get, and add tax yourself.
- Is anything sent to SimpleVerifier?
- No. The sum is done in your browser.
A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
