Which one is for you
Pick AutoSend if
- Fits if you send a few thousand app emails a month and want the lowest bill
- Works for small projects that only need transactional mail, not campaigns
Look elsewhere if
- Skip it if you want a free plan or a trial, as the entry price is $1 a month
- Too light for webhooks on Hobby: they start on the $10 Starter plan
- Pricey if you go past your quota, with extra emails at $0.0020 each on the lower tiers
- Watch out: marketing is a paid add-on at every size, for example $5 instead of $1 on Hobby
- Watch out: refunds only cover paid plans with no usage, within 7 days, and Hobby isn't eligible
Pick Postmark if
- Fits if you want password resets kept on a separate stream from your newsletters
- Works for apps that need to look back at exactly what an email said weeks later
Look elsewhere if
- Pricey if you send 50,000 emails a month, at $55 with no yearly discount
- Skip it if you want a free plan to run a small app on, as it's 100 emails a month with no tier until 10,000
- Tight if you're on Basic, with 4 users, 5 sending domains and no inbound email
- Not for you if you want a dedicated IP below 300,000 emails a month, and each one is $50 a month on Pro or higher
- Watch out: DMARC reports are an add-on from $14 a month per domain
How we grade them
| 2.0GPAAutoSendFair | 2.2GPAPostmarkFair | |
|---|---|---|
| Value for money | A$1 a month for 3,000 transactional emails. Email sending tools start at $9 for the cheaper quarter, so this is well under 60% of that. | 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 | FNo free plan and no trial. The vendor says the $1 price is there to keep abuse off shared IPs, and Hobby isn't refundable. | 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 | CEmail API, SMTP, domain warm-up and validation, and a marketing tier with campaigns. Hobby has no webhooks and only 7 days of data kept. | 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 | CNo store rating on record. You add sending domains and set up DNS before anything goes out. | 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 dashboard with a REST API and SMTP. No integrations list on its pages. | 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 | cheap transactional email with an API | 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.
