Which one is for you
Pick MailBaby if
- 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
Look elsewhere if
- 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
Pick SMTP.com if
- Fits if you already send 50,000 emails a month and want one flat monthly price
- Works for senders moving from SendGrid or Mailgun who want help with the switch
Look elsewhere if
- Skip it if you want to try sending before you pay, since there's no free plan or trial
- Too light for apps that need webhooks, templates or incoming email, which the listing doesn't mention
- Pricey if you send a few thousand emails a month, as the smallest plan is $25 for 50,000
- Watch out: Reputation Defender and Insight Engine each add 20% of the plan price, $5 a month each on Essential
- Tight if you want a dedicated IP on Essential, which sends from a shared one until the $80 plan
How we grade them
| 2.0GPAMailBabyFair | 1.8GPASMTP.comWeak | |
|---|---|---|
| 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. | CGraded on 50,000 emails a month: Essential is $25 for exactly that, on a shared IP, the middle of this category at that volume. Reputation Defender and Insight Engine add $5 a month each, and a dedicated IP means Starter at $80 for 100,000. |
| Free plan and trial | FNo free plan or trial. The $1 a month is there to keep the account active. | FNothing free: no free plan and no trial. The smallest plan is $25 a month, so you pay before you've sent a single email. |
| Features | CSpam 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. | CSMTP relay and an email API, detailed delivery reports, dedicated IPs from the $80 plan, and paid add-ons that weed out bad addresses as you send. It handles the sending, but nothing on record covers templates, webhooks or inbound email. |
| Ease of use | DNo 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. | CJudged on how fast a developer sends a first email: you choose a plan and pay before you get to send, then use SMTP or the API. No rating on record. Managed onboarding and migration help are offered if you're moving from another provider. |
| Platforms and integrations | BWeb account with an API, a WordPress plugin and connections for cPanel, Plesk, hMail and Webuzo. | BWeb, with an SMTP relay and an email API, plus WordPress, Shopify, Google Forms, Google Docs, Wufoo, Airtable, Trello and Slack. No desktop or phone app, so B is the top. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
