The report card
Best for email, phone and address validation
EmailOversight validates emails, phone numbers and postal addresses and appends data, with email tiers from $70 a month for up to 10k. The pricing page does not say what the 10k counts, phone, appends and activity are billed per record, and the top tier is by quote.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | $70 a month for up to 10k is in the dearer quarter of deliverability tools, which starts at $49. The next steps are $125, $400 and $750 a month. |
| Free plan and trial | C | Sign-up gives 200 free credits to test list cleaning and the API. There is no free plan, and the listing does not say if a card is needed. |
| Features | B | Email, phone and postal validation, data append and email activity. Nothing in the listing is missing from the validation job. |
| Ease of use | C | No store rating on record. You upload lists or use the API, so some setup is needed. |
| Platforms and integrations | C | Web only on the listing, with an API and docs. No integrations or apps are 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 EmailOversight is for
- Fits if you clean email, phone and postal data in one place
- Works for marketing teams with lists above 10,000 a month
Who it is not for
- Pricey if your list is small, as the entry step is $70 a month
- Watch out: the page does not say whether 'up to 10k' counts records or emails
- Watch out: phone, append and activity are billed per record on top of the email tiers
- Watch out: the biggest tier is quote only, and prepaid rates are not shown
Good to know
Good for
- Marketers who clean large lists before a send
- Sites that need real-time checks on sign-up forms
- Teams that also want phone or postal checks from one vendor
Worth knowing
- Only the first four volume steps of email validation show a price; the top tier is by quote.
- The page does not name the unit behind 'Up to 10k', so confirm whether it counts records or monthly checks before buying.
- Phone validation, appends and email activity are billed per record, separate from the email validation tiers.
- Month-to-month billing and prepaid credit options are both mentioned, but the prepaid rates are not shown.

It costs $840 a year.
