What it is, who it suits, its grades and the ten things to know first
2.4
GPA, above 18 of the 38 other email verification and deliverability tools we grade

The report card
Best for cleaning email lists and checking sign-ups
Email Hippo checks email addresses, with bulk file cleaning on CORE and a real-time API on MORE, from $9.88 for 1,000 checks. You get 100 free checks, but CORE has no real-time checks, the pricing calculator needs script to load, and the billing basis of the starting price is not stated.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | From $9.88 for 1,000 checks, inside the $10 cheaper quarter of deliverability tools. The page does not say if that is monthly or one-off, and INSIGHT and ASSESS cost $12.26 and $14.63. |
| Free plan and trial | C | 100 free checks with no card. There is no ongoing free plan. |
| Features | C | Bulk cleaning, real-time checks, enrichment and fraud signals. CORE does not do real-time checks, so each use sits on a different product. |
| Ease of use | C | No store rating on record. You upload files or connect an API, so there is some setup. |
| Platforms and integrations | B | Web and API, with HubSpot, Salesforce, Zapier, Formstack and Unbounce listed. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Email Hippo is for
- Fits if you clean a list now and then and want a small pay-as-you-go pack
- Works for teams that want fraud and risk signals on sign-ups
Who it is not for
- Skip it if you want real-time checks on CORE, since they need a MORE, INSIGHT or ASSESS subscription
- Tight if you stay free, as it is 100 checks once
- Watch out: the starting price of $9.88 is for 1,000 checks and the billing basis is not stated
- Watch out: a minimum transaction fee applies to pay-as-you-go
- Watch out: above 2.5 million checks a month you need a quote
Good to know
Good for

- 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.
