How we grade them
| 2.4GPAAhaSendFair | 2.2GPAPostmarkFair | |
|---|---|---|
| Value for money | B$10 a month for 25,000 emails is inside the cheapest quarter of email sending tools, which starts at $10. Max is $80 for 100,000 emails, and extras are $0.50 per 1,000. | DGraded on 50,000 emails a month: $55 on Basic or $60.50 on Pro, billed monthly only. That's the dearest in this category at that volume, roughly twice the middle. Bootstrapped companies can ask for $75 of credit. |
| Free plan and trial | CA free plan with 1,000 emails a month, 3 domains and 1 to 7 days of log retention, no card needed. It is a cap you will hit. | CA free developer plan that never expires and needs no card, but it's 100 emails a month with no way to buy more. That's for testing an integration, not running an app. |
| Features | BREST API and SMTP relay, sandbox mode, local webhooks, inbound routing, a campaign builder and a management API. The listing shows no gap in the core job. | BAPI and SMTP with SDKs, separate streams for app and bulk email, inbound email turned into JSON, templates, 45 days of message history and DMARC reports as an add-on from $14 a month. It covers the job; inbound needs Pro. |
| Ease of use | CA web dashboard and API with no rating on record. You verify domains and wire it into your code. | CJudged on how fast a developer sends a first email: official SDKs, a sandbox mode, ready-made templates for resets and receipts, and migration guides. You'll still verify a domain first. No rating on record. |
| Platforms and integrations | CWeb only, with an API and no integration list on the pages read. | BWeb, with an API and SMTP, plus Zapier, WordPress, Stripe, Slack, Supabase, Bubble, Netlify and Datadog. No desktop or phone app, so B is the top. |
| Best for | developers sending transactional email | app email kept apart from marketing sends |

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.
