Email verification QA for data and list brokers
If you sell lists, run a verification pass before delivery and report it as it is: valid, risky and invalid, with reasons. An address the mailbox check cannot confirm is risky here, never valid, so your own report never claims more than was checked. Business ($99 a month) covers 1,000,000 emails a month; Agency ($249) covers 3,000,000.
Plan details as of 23 Oct 2026. The pricing page is the source of truth.
The use case
A buyer disputes a list because it bounced. A verification pass before delivery, with the results file kept, gives you a record of what was checked and when. It does not make the list immune to decay: confirmed mailboxes are cached for about two weeks, and addresses go bad after that.
The workflow
- 1
Verify before delivery
Run the final file through verification and export valid, risky and invalid separately.
- 2
Be exact in the product description
Sell valid as valid. Describe risky as unconfirmed. Do not relabel it.
- 3
Use the API for large or recurring files
Call the API from your pipeline. Business includes 100,000 calls a month, Agency 300,000.
- 4
Plan for the speed
Very large files run for days on shared capacity. Quote delivery times with that in mind.
- 5
Keep a record
Keep the results file with the job, dated, in case a buyer asks.
Which plan fits
Business ($99) for 1,000,000 emails a month, Agency ($249) for 3,000,000. Past the monthly volume, lists keep running in a slower shared lane; they are never refused. If you regularly verify tens of millions of rows a month, this self-serve plan is not sized for you.
Full speed is a monthly volume, not a promise of hours. Mailbox checks are paced and the day's check capacity is shared between customers, so a very large list takes days. It queues rather than failing, and the job card shows an estimated finish time. Plan client deadlines around that.
We do not vouch for how a list was collected. Brokers remain responsible for consent and lawful sale of the data.

Competitor figures are the cheapest published route that covers the volume in one month: a subscription tier whose allowance covers it, or the pay-as-you-go pack bought again each month. They price verification credits only; we have not compared their team features. Prices change, so check each page before you decide. Full speed is a monthly volume, not a promise of hours. Mailbox checks are paced and the day's check capacity is shared between customers, so a very large list takes days. It queues rather than failing, and the job card shows an estimated finish time.

Common questions
- Can I call an address valid if you could not confirm it?
- We never do. Anything the mailbox check could not confirm is returned as risky, and your own reports should say the same.
- How do seats and client workspaces work?
- A seat is one person, the owner included: Business has 5 seats and Agency has 15. Teammates share the account's lists, monthly volume and API keys. Client workspaces are on Agency: you pick a client when you upload a list, then filter History and exports by client. Deleting a workspace keeps its lists; they just lose the label.
- What does the priority lane do, and how fast is it?
- Big lists on Business and Agency go ahead of other big lists in the shared queue, within the plan's monthly full-speed volume. Small lists under 2,000 rows always run first on every plan. Full speed is a monthly volume, not a promise of hours. Mailbox checks are paced and the day's check capacity is shared between customers, so a very large list takes days. It queues rather than failing, and the job card shows an estimated finish time. Plan client deadlines around that.
- Can we call it from our own tooling?
- Yes. Business includes 100,000 API calls a month and Agency 300,000, then $1.00 per 1,000 on monthly billing. Docs are at /docs/api.
