Email verification time estimator: how long will my list take, and what will it cost?
In short: Enter the number of addresses and get the time at the shared standard pace, the cheapest way to run it once and the one-time pack that covers it. Limit: A time estimate at a shared pace, not a promise; the queue and slow mail servers change it.
Email verification time depends on list size and the shared checking pace, which is about 13,000 mailbox checks a day. Enter the number of addresses and this estimator gives the time at that pace, the first free checks, the cheapest way to run the list once from the current plans, and the one-time pack that covers it.

- The shared standard pace is about 13,000 mailbox checks a day, so 10,000 addresses take about 19 hours. A list that runs past a day queues and its card shows the finish time; nothing is cut off.
- The first 100 are free with a Google sign-in, no card. The other 9,900 cost $39 for the whole job as One month of Pro ($39/mo, 100,000 a month at full speed, cancel anytime).
- Or a one-time pack, no subscription: 10,000 email checks for $15.
- Duplicates and addresses we can't check don't use a check, so the real count is often lower than the rows in the file.
Sample result
A list of 50,000 addresses takes about 4 days at the shared pace, and the first 100 checks are free.

How do I estimate how long it takes to verify an email list?
- Enter the number of email addresses on your list, or pick a common size.
- Read the time: the list size divided by the shared daily pace, rounded up.
- Read the price: the first free checks, then the cheapest way to run the rest once and the one-time pack that covers it.
- Start with the free checks, or open the pricing page to compare plans.
Example
- You enter
- A list of 50,000 addresses.
- You get
- The time at the shared standard pace (the list size divided by the daily pace, rounded up to whole days), the first free checks, the cheapest way to run the list once from the current plans, and the smallest one-time pack that covers it, with a link to start the free checks.
- Limits
- An estimate at a shared pace, not a promise. Lists up to 1,000,000 addresses. Nothing is uploaded; you enter a number. Prices and the pace come from the live plan and pack settings.
How is the time worked out?
The estimate divides your list size by the shared standard pace, about 13,000 mailbox checks a day for everyone. A list under that runs in hours; a bigger one queues, and its card on the dashboard shows the finish time. Nothing is cut off.
It is an estimate, not a promise: the real time depends on how busy the shared queue is, and on the mail servers on your list, because some answer slowly.
What does verifying the list cost?
The first 100 checks are free with a Google sign-in, no card. Beyond that the estimator uses the same price function as the cost calculator: the cheapest way to run the list once across the current plans, plus the smallest one-time pack that covers it. A change to a plan or pack changes the estimate.
Duplicates and addresses we can't check don't use a check, so clean the list first with the email list counter to see the real number.
Can I make it faster?
Remove duplicates, blank rows and badly formatted addresses before you upload, since they never need a check. Plans differ in the volume they run at full speed each month, and a list past that runs in a slower lane, never refused. See pricing for the current numbers.

Common questions
- How long does it take to verify 10,000 emails?
- At the shared standard pace of about 13,000 checks a day, a list of 10,000 addresses takes under a day. Enter your own number above for the exact estimate.
- How long does it take to verify 100,000 emails?
- At about 13,000 checks a day it takes about 8 days at the shared pace. Larger lists queue, and the dashboard card shows the finish time.
- Why does a big list take days?
- Each address is checked against its mail server, and the checks run at a shared daily pace so that the sending address keeps a good reputation. Big lists queue and nothing is cut off.
- Is the estimate a guarantee?
- No. It is the list size divided by the shared pace. The real time depends on how busy the queue is and how fast the mail servers on your list answer.
- How much of my list is free to check?
- The first 100 checks are free with a Google sign-in, no card.
- Does the estimator see my list?
- No. You enter a number. Nothing is uploaded and nothing is stored.

The calculator makes the case better than we can.
Every per-address model above recurs each time you clean. A monthly plan with no per-email fees does not.
- Pro is never cut off: the first 100,000 emails a month run at full speed, then big lists run slower
- The email finder and enrichment included
- Published limits, so nothing is a surprise later
