Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.0
GPA, above 8 of the 61 other email verification and deliverability tools we grade
Reacher checks whether an email address exists by talking to the recipient's mail server, without sending a message. It is open-source software under the MIT license, written in Rust and run on your own infrastructure. A hosted version is offered through a separate service, No2Bounce, and a proxy service handles port 25 traffic.
To get you started, here are 8 things to know about Reacher, taken from its own pages and our grades.
Mail servers often block verification traffic from unknown IPs, and the hosted version with catch-all checks is a separate service.
- 1
Best for developers hosting their own email verifier
Reacher is an open-source email verification engine you host yourself, under the MIT license.
- 2
It is free
Reacher has no paid plan at all. The open-source engine is free to download and run yourself under the MIT license.
- 3
It runs on Web
Web.
- 4
SMTP-based address check
Checks whether a mailbox exists without sending an email; the GitHub project describes it as written in Rust.
- 5
HTTP backend
The repository comes with an HTTP backend, so the verifier can be called as an API from your own applications.
- 6
Modifiable source
The MIT-licensed code can be downloaded, changed and built into your own verification system.
- 7
A 2.0 GPA, above 8 of 61
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 developers hosting their own email verifier
Reacher is an open-source email verification engine you host yourself, under the MIT license. Mail servers often block verification traffic from unknown IPs, and the hosted version with catch-all checks is a separate service.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Free software, but you supply and run the server, which makes it a C under the ladder. The proxy service and hosted checks are priced separately and were not read. |
| Free plan and trial | B | The engine is free to download and run under MIT. It costs you a server and an IP that mail servers will accept. |
| Features | C | SMTP-based address check behind an HTTP backend. Catch-all checks come from a separate hosted service. |
| Ease of use | D | Self-hosting, and an HTTP API to call it. No rating on record. |
| Platforms and integrations | C | Web only, and no integrations are listed. You get the source and an HTTP backend. |
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 Reacher is for
- Fits if you can run a server and want verification inside your own system
- Works for developers who want to read and change the source
Who it is not for
- Skip it if you do not want to host and maintain a server
- Watch out: the pricing page says mail servers often limit or block checks from unknown IPs
- Watch out: catch-all checks and hosted verification are a separate service, No2Bounce
- Watch out: the SMTP proxy service is separate and paid; its prices were not read

What paid plans start at, a month (each step along is roughly double) →
Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
Reacher is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. 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.
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. Reacher’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.
