Worth knowing
Abstract Email Validation
- The free tier is 100 requests a month, which suits testing rather than lists.
- Prices shown are for the entry volume of 5,000 requests a month; more volume costs more and the page sets it in the dashboard.
- The page says annual billing saves 10%, but its source shows the same figures for monthly and yearly, so the monthly price was not confirmed.
- The pricing page still carried a holiday discount banner with a January 3rd end date, which looked out of date.
QuickEmailVerification
- The free tier gives 100 credits a day; there is no larger free monthly bucket.
- The pricing page was running a limited-time sale with no end date shown; the prices listed here are the regular ones.
- A Per Day Credits monthly subscription (100 to 50,000 credits a day) also exists; only its $900 a month top step was readable, so it is not listed as a plan.
- Web dashboard and API only; no desktop or mobile app is listed.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
