How Long Does It Take to Verify an Email List?

Email list verification time is the number of addresses divided by the checking pace. The email verification time estimator does the sum for your list size and shows the cost beside it.

It is an estimate. The queue and slow mail servers change the real time.

Why a list takes time

Each address is checked against its own mail server, and the checks run at a shared daily pace so the sending address keeps a good reputation. A list under one day's pace runs in hours. A bigger list queues, its card on the dashboard shows the finish time, and nothing is cut off.

The by-hand way

1. Count the unique addresses: duplicates and blank rows never need a check. The email list counter does it.
2. Divide by the daily pace shown in the estimator.
3. Round up to whole days.

Step 1: enter the list size

Type the number of addresses, or pick a common size.

Step 2: read the time and price

You get the time at the shared pace, the first free checks, the cheapest way to run the list once and the one-time pack that covers it. The price comes from the same function as the email verification cost calculator.

What the estimator cannot do

• It can't see your list, so it can't know how many rows are duplicates.
• It can't predict a busy queue.

Next: start with the free checks

The first 100 checks are free with a Google sign-in, no card. Start at the verify page, or compare plans on pricing.
