How we grade them
| 2.6GPATwilio SendGridGood | 2.6GPABird EmailGood | |
|---|---|---|
| Value for money | BGraded on 50,000 emails a month: Essentials is $19.95 for exactly that, in the cheaper quarter of this category at that volume. It's thin for the money, with 1 teammate and 3 days of activity, and Pro at $89.95 is where dedicated IPs and SSO start. | BGraded on 50,000 emails a month, worked out from the listed rate: Startup charges $0.40 per 1,000, so that's $20 of balance a month, more than its $15 deposit covers.

| Free plan and trial | 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. | CFree for good: 1,000 emails a month, but only 50 a day and 1 sending domain, and sending simply stops at the limit. Enough to try the API, not to run an app on. |
| Features | BAPI and SMTP, event webhooks, an inbound parse webhook, dynamic templates, domain authentication, address validation and EU data residency. That covers the whole job. Testing credits, subusers and dedicated IPs wait for Pro. | BAPI, SMTP, typed SDKs, a CLI and an MCP server, inbound email and mailboxes, signed webhooks, DKIM and DMARC setup, templates and broadcasts, with SMS and WhatsApp on the same API. It covers the whole job; dedicated IPs start at $250. |
| Ease of use | 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. | CJudged on how fast a developer sends a first email: SDKs for TypeScript, Python, Go and PHP plus a CLI, once a domain is set up. No rating on record. Coming from SparkPost means a new API, which Bird says to review with its team. |
| Platforms and integrations | 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. | BWeb, with an API, SMTP, SDKs, a CLI and an MCP server, plus Claude, ChatGPT, Cursor, GitHub Copilot, Replit, Lovable, v0 and Bolt.
