    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    • The pricing page still carried a holiday discount banner with a January 3rd end date, which looked out of date.

    Email Hippo

    • Prices are shown as a starting figure for 1,000 checks; the pricing calculator loads by script and the billing basis of the starting figure was not stated.
    • CORE does not offer real-time checks; real-time use needs a MORE, INSIGHT or ASSESS API subscription.
    • A minimum transaction fee applies to pay-as-you-go purchases.
    • Enterprise quotes are required above 2.5 million checks a month, and above 1 million for ASSESS.

    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.
