How we grade them
| 2.2GPASMTP2GOFair | 2.2GPAturboSMTPFair | |
|---|---|---|
| Value for money | CGraded 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. | 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 | CFree 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. Enough for a test, tight for a live app. | BUp 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 | CAPI 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. | CAn 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 | CJudged 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. | CNo 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 | BWeb, 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. | CA web dashboard, SMTP and an API; the listing names no integrations. |
| Best for | relaying email from apps, sites and office printers | SMTP relay with a free plan and a dedicated-IP step |

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.
