Pick Courier if

How we grade them
| 2.4GPACourierFair | 2.6GPATwilio SendGridGood | |
|---|---|---|
| Value for money | CThe Developer plan is free and Business is $0.005 per send with no per-seat fees, so 10,000 sends cost $50, in the ordinary range for email tools at low volume and above it at high volume. | BGraded on 50,000 emails a month: Essentials is $19.95 for exactly that, in the lowest-priced quarter of this category at that volume. It comes with 1 teammate and 3 days of activity, and Pro at $89.95 is where dedicated IPs and SSO start. |
| Free plan and trial | BDeveloper is free for 10,000 sends a month with journeys, broadcasts, CLI and SDKs, which one person can live on. | CNo lasting free plan, but a 60-day trial with no card: 100 emails a day, enough to wire it into your app and test. After that you're paying. |
| Features | CRouting across channels, journeys, design studio, inbox and an AI step. It routes through your own email provider rather than delivering mail, and add-ons like Device Preview start at $20 a month. | BAPI and SMTP, event webhooks, an inbound parse webhook, dynamic templates, domain authentication, address validation and EU data residency. That covers the job. Testing credits, subusers and dedicated IPs wait for Pro. |
| Ease of use | CNo rating on record. You connect providers, build templates and journeys, and wire in SDKs. | CJudged on how fast a developer sends a first email: client libraries, interactive API docs and a setup guide on every plan, but you'll authenticate a domain before mail goes out properly. No rating on record. |
| Platforms and integrations | BWeb service with SDKs, a CLI, an MCP server and connections to SES, Mailgun, Postmark, SendGrid, Twilio, Slack, Teams and FCM. | BWeb, with a REST API, client libraries, SMTP and webhooks, so anything that speaks SMTP can use it. The listing names no ready-made integrations, and there's no desktop or phone app, so B is the top. |
| Best for | notifications across email, SMS, push and chat | app email for teams already on Twilio |

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.
