Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.0
GPA, above 9 of the 50 other email sending services we grade
MailBaby is an outbound email smart host: a server sends its mail through MailBaby, which scans it for spam and malware before delivery and manages the sending IP reputation. It is aimed at web hosts and businesses that want to contain outgoing spam, and it is not built for marketing email. Billing is a small monthly fee plus a charge per thousand emails.
To get you started, here are 8 things to know about MailBaby, taken from its own pages and our grades.
You point your server at it, need SPF, and must do DKIM for your own domain on your server, and STARTTLS is required.

Keep it
To replace MailBaby 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 scanning the outgoing mail from your servers
MailBaby is an outbound smart host: your server sends through it, and it scans for spam and malware before delivery. It costs $1 a month plus $0.20 per 1,000 emails, and it isn't built for marketing email.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | $1 a month plus $0.20 per 1,000 emails, which works out to about $3 for 10,000. That's under 60% of what the cheaper quarter of email sending tools starts at. |
| Free plan and trial | F | No free plan or trial. The $1 a month is there to keep the account active. |
| Features | C | Spam and malware filtering, SMTP login, an API and WordPress plugin, unlimited servers, IP reputation handling and delivery logs. It's SMTP only and does one narrow job. |
| Ease of use | D | No store rating on record. You point your server at it, need SPF, and must do DKIM for your own domain on your server, and STARTTLS is required. |
| Platforms and integrations | B | Web account with an API, a WordPress plugin and connections for cPanel, Plesk, hMail and Webuzo. |
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 MailBaby is for
- Fits if you run a web host or servers and want to stop outgoing spam leaving them
- Works for sites sending small volumes, where $1 a month plus usage is enough
Who it is not for
- Skip it if you want to send marketing, cold email or lists: the FAQ says it isn't designed for them
- Skip it if you want a free plan or trial, as there isn't one
- Not for you if you want DKIM for your own domain handled for you: it signs only its own hostname
- Watch out: blocked messages are billed at the same $0.20 per 1,000 as delivered ones
- Watch out: the FAQ lists restricted business types
Good to know
Good for
- Web hosts that need to stop compromised customer accounts from spamming
- Servers with a small amount of outgoing mail and no wish to run mail infrastructure
- Businesses that want one low-cost smart host for many servers
Worth knowing
- The FAQ says it is not designed for email marketing, cold email or lists, and lists a number of restricted business types.
- Blocked messages are billed at the same $0.20 per 1,000 as delivered ones; deny rules for blocked mail are free up to 1,000,000 messages.
- SPF is required, and MailBaby signs only its own transport hostname, so DKIM for your domain must be done on your own server.
- STARTTLS is required to connect, and the product is SMTP only: the FAQ says it does not offer installation services.

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 MailBaby 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: 37 of the 50 other email sending services grade higher. It costs $12 a year.
What you could not
- Mail servers with a good name among inbox providers.
- It plugs into other products, cPanel, Plesk and hMail among them, and has an API.
What this rests on. MailBaby’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.
