Credits can be bought as needed or taken as a monthly allotment, and verification runs by bulk upload, batch or API.

You pick scans and credits in a web platform.

The report card
Best for email checks plus threat scans in its Zuvo platform
Webbula's Zuvo verifies addresses and scans for threats, from $24.95 a month for 2,500 credits. Per-credit rates for On Demand sit behind a slider, and Webbula also sells data appends and audience segments that have nothing to do with it.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | $24.95 a month for 2,500 credits, close to the category's $23 middle, though that's about 1 cent a credit. |
| Free plan and trial | C | 100 free credits on sign-up. No free plan. |
| Features | C | Four Protect scans, verification, threat detection, bulk, batch and API, and team tools. The listing shows separate products and unread per-credit rates. |
| Ease of use | C | No store rating on record. You pick scans and credits in a web platform. |
| Platforms and integrations | C | Web platform and API only, with no integrations or apps 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 Webbula is for
- Fits if you want threat scans alongside address checks
- Works for small teams on a fixed monthly credit pack
Who it is not for
- Watch out: On Demand and add-on credit rates sit behind a slider and weren't read
- Skip it if you want a free plan, as it's only 100 sign-up credits
- Skip it if you want apps or integrations, as none are listed
- Watch out: enterprise needs go through sales rather than listed plans
Good to know

Keep it
Nothing Webbula does is plain enough to make in a weekend. The 2 things listed below take a company.
That makes this kind of software worth paying for, not this one in particular: 39 of the 61 other email verification and deliverability tools grade higher. It costs $299.40 a year.
What you could not
- Checking that an address exists without writing to it.
- An API that other software can build on.
What this rests on. Webbula’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
