Best for SMTP relay with a free plan and a dedicated-IP step
turboSMTP is an SMTP relay and email API on European infrastructure, with a free plan of 200 emails a day and paid plans from $12.46 a month billed annually for 15,000 emails. Webhooks, a dedicated IP and phone support wait on Pro, which starts at 100,000 emails.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | $12.46 a month billed annually ($14.95 monthly) for 15,000 emails, between the cheaper quarter ($10) and the dearer quarter ($20). |
| Free plan and trial | B | Up to 200 emails a day by SMTP and API with SPF and DKIM and no time limit, which a small site can live on, though it allows only 1 sending domain. |
| Features | C | An SMTP relay and web API, subaccounts, analytics and email validation credits, but webhooks, a dedicated IP and phone support are Pro only. |
| Ease of use | C | No store rating on record. You verify a sending domain with DNS records and wire up SMTP credentials or an API key before the first email goes out. |
| Platforms and integrations | C | A web dashboard, SMTP and an API; the listing names no integrations. |
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 turboSMTP is for
- Fits if you send a few thousand emails a month and want a free plan with no time limit
- Works for agencies that need subaccounts on Pro
Who it is not for
- Tight if you need webhooks or a dedicated IP, as both are Pro features
- Pricey if you want a dedicated IP at small volume, since Pro starts at 100,000 emails and $79.95 a month billed monthly
- Watch out: prepaid packages run from $49 for 50,000 emails and their credits expire after one year
- Watch out: listed prices exclude VAT where it applies
- Skip it if you need several sending domains on the free plan, which has 1
Good to know
Good for
- Small senders who fit in 200 emails a day on the free plan
- Teams that want EU-hosted SMTP relay with GDPR-minded terms
- Agencies that need subaccounts for several clients
Worth knowing
- A dedicated IP, webhooks and phone support are Pro features; Basic and Free have none of them.
- Pay-as-you-go prepaid packages run from 50,000 emails for $49 to 1,000,000 for $790, and credits expire after one year.
- Listed prices exclude VAT where it applies, and Enterprise is billed the month after on usage.
- Pro starts at 100,000 emails a month, so a small sender wanting a dedicated IP still pays $79.95 monthly.

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 turboSMTP 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: 17 of the 26 other email sending services grade higher. It costs $149.52 a year.
What you could not
- Mail servers with a good name among inbox providers.
- Checking that an address exists without writing to it.
- An API that other software can build on.
What this rests on. turboSMTP’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.
