Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.6
GPA, above 31 of the 38 other email verification and deliverability tools we grade
Verifalia checks email addresses in bulk or one at a time and sorts each into Deliverable, Undeliverable, Risky or Unknown, with one of more than 40 status codes explaining why. It can be used through a web client area, an API with open-source SDKs, or Zapier and Pipedream. It is made by Cobisi Research, an Italian software company.
To get you started, here are 9 things to know about Verifalia, taken from its own pages and our grades.
A web client area and an API, with no rating on record.
- 1
Best for cleaning email lists, bulk or by API
It is a web client and an API only, so there is nothing to install and nothing beyond checking.
- 2
Paid plans start at $9 a month
As its pricing page puts it: $9 per month, billed yearly.
- 3
There is a free plan
25 free verification credits every day, which expire at the end of the day.
- 4
It runs on Web
Web.
- 5
Bulk list cleaning
Upload a list as plain text, CSV or Excel (.xls or .xlsx), up to 100 MB per list, then download the results and choose which addresses to keep.
- 6
Real-time verification API
A real-time API with free, open-source SDKs for .NET, Go, Java, JavaScript, PHP and Ruby, usable for single checks or for batches.
- 7
Detailed status codes
Each address is marked Deliverable, Undeliverable, Risky or Unknown and given one of more than 40 status codes with an explanation.
- 8
A 2.6 GPA, above 31 of 38
That is against the other email verification and deliverability tools we grade, on value, the free plan, features, ease of use and platforms.

The report card
Best for cleaning email lists, bulk or by API
Verifalia checks addresses one at a time or in bulk and sorts each as deliverable, undeliverable, risky or unknown, with one of 40-odd status codes saying why. The free plan gives you 25 checks a day, and past that you buy credit packs. It is a web client and an API only, so there is nothing to install and nothing beyond checking.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | $9 a month on yearly billing for the Starter plan is under the $10 the cheapest quarter of deliverability tools starts at. Beyond the daily credits you buy packs, such as 10,000 credits for $49.90. |
| Free plan and trial | C | 25 free credits a day that expire at midnight. Fine for checking a signup form, but any real list needs packs, and the Free plan processes on a best-effort basis. |
| Features | B | Bulk upload up to 100 MB, a real-time API with open-source SDKs, 40-plus status codes, disposable, free-mail and typo detection, and free de-duplication. The listing shows no gap in the checking itself. |
| Ease of use | C | A web client area and an API, with no rating on record. You upload a list or write code against the SDKs, so there is some setup either way. |
| Platforms and integrations | B | Web and API only, with SDKs for .NET, Go, Java, JavaScript, PHP and Ruby, plus Zapier and Pipedream. No desktop or mobile app. |
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 Verifalia is for
- Fits if you clean a list now and then and want credit packs that do not expire
- Works for developers who want to verify addresses at signup through an API
Who it is not for
- Tight if you want more than 25 free checks a day, because the allowance resets daily and does not roll over
- Watch out: higher quality levels use more credits per address, so the headline price per check goes up
- Skip it if you want an app on your phone or desktop, as it is a web client and API only
- Pricey if you clean big lists often: Enterprise is $199 a month and Ultimate $499, before any credit packs
- Watch out: the pricing page shows monthly-billing prices nowhere we could read, only per month billed yearly
Good to know
Good for
- One-off list cleaning paid for with credit packs that do not expire
- Developers who want an API with SDKs in several languages
- Teams wiring verification into other apps through Zapier or Pipedream
Worth knowing
- Every plan includes only a daily allowance of credits that expires at day's end; anything beyond it is bought as credit packs, such as 10,000 credits for $49.90.
- One credit covers one standard-quality check; higher quality levels cost more per address.
- The pricing page shows plan prices as per month billed yearly; the monthly-billing prices were not displayed when read.
- Web client area and API only; there is no desktop or mobile app.

Keep it
Nothing Verifalia does is plain enough to make in a weekend. The 3 things listed below take a company.
It is one of the better ones too: its GPA of 2.6 is higher than 31 of the 38 other email verification and deliverability tools we grade. It costs $108 a year.
What you could not
- Checking that an address exists without writing to it.
- It plugs into other products, Zapier and Pipedream among them, and has an API.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Verifalia’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.
