Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 1 of the 11 other email sending services we grade
SMTP2GO is an outgoing email service that sends email from apps, websites, email clients and devices such as printers through its SMTP relay or HTTP API. It sets up SPF and DKIM for your domains, tracks every message through to bounce, spam complaint or unsubscribe, and runs data centers in the US, Europe and Australia. Plans are priced by emails a month, with 1,000 a month free.
To get you started, here are 9 things to know about SMTP2GO, taken from its own pages and our grades.
Sign-up refuses Gmail and Yahoo addresses, so you need a work domain.
- 1
Best for relaying email from apps, sites and office printers
SMTP2GO is a straightforward relay: point your app, website or even the office printer at it and it sends, with SPF and DKIM set up for you and data centers in the US, Europe and Australia.
- 2
Paid plans start at $15 a month
As its pricing page puts it: $15 per month for 10,000 emails, billed monthly.
- 3
There is a free plan
1,000 emails a month, limited to 200 a day, with 5 days of email reporting and ticket support. Extra emails are not allowed. No credit card needed.
- 4
It runs on Web
Web.
- 5
SMTP relay and HTTP API
Send through SMTP from an app, a mail client, a server or a device, or through a REST API with code examples in JavaScript, Node.js, PHP, Ruby and Python.
- 6
Delivery tracking and reports
Real-time reports follow each email to delivery and show bounces, spam complaints and unsubscribes, with weekly summaries and alerts on sudden bounce rises.
- 7
Automatic SPF and DKIM
Domain authentication is handled for you, along with feedback loops, blacklist monitoring and spam trap detection on every plan.
- 8
A 2.2 GPA, above 1 of 11
That is against the other email sending services we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace SMTP2GO you would be making mail servers with a good name among inbox providers. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for relaying email from apps, sites and office printers
SMTP2GO is a straightforward relay: point your app, website or even the office printer at it and it sends, with SPF and DKIM set up for you and data centers in the US, Europe and Australia. 50,000 emails is $30 a month, with two months free if you pay yearly. There's nothing on record for receiving email, though, and the free plan stops at 1,000 a month.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Graded on 50,000 emails a month: Starter is $30 a month at that volume, with two months free if you pay yearly. That sits in the middle of what this category charges for that much sending. A dedicated IP and email testing need Professional at $75. |
| Free plan and trial | C | Free for good with no card: 1,000 emails a month, but only 200 a day, with 5 days of reports, and extra emails can't be bought. Chat and phone help last 14 days. Fine for a test, tight for a live app. |
| Features | C | API and SMTP sending, automatic SPF and DKIM, delivery reports with bounce alerts, blacklist monitoring, three data regions and subaccounts. It does the sending job fully, but that's a smaller job: nothing on record covers receiving email or templates. |
| Ease of use | C | Judged on how fast a developer sends a first email: copy the SMTP details or use the API, with code examples in five languages, once your domain is added. No rating on record. Sign-up refuses Gmail and Yahoo addresses, so you need a work domain. |
| Platforms and integrations | B | Web, with an SMTP relay and REST API that work from apps, servers and devices, plus WordPress, Google Workspace, Salesforce, Zoho CRM, Pipedrive, WHMCS, Laravel and Django. No desktop or phone app, so B is the top. |
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.

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
To replace SMTP2GO you would be making mail servers with a good name among inbox providers. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 9 of the 11 other email sending services grade higher. It costs $180 a year.
What you could not
- Mail servers with a good name among inbox providers.
- It plugs into other products, WordPress, Google Workspace and Salesforce among them, and has an API.
What this rests on. SMTP2GO’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.
