Rasket
Rasket is an email API for developers: one REST API, a dashboard and typed SDKs for transactional email and broadcasts, with inbound mail, signed webhooks and an MCP server in the same product and on the same key.
Resend
Resend is an email API with a dashboard, nine official SDKs and a documentation set written for agents as well as people; its transactional plans and its marketing plans are priced apart.

Key takeaways

Where Resend wins

Resend publishes nine official SDKs to our two, so if your service is written in Rust, Elixir, Java or .NET they have a client for you today and we do not. They also run an SMTP relay, which matters if you are pointing an existing framework mailer or an off-the-shelf application at a provider rather than writing the call yourself. On the rows a reader usually comes here for — inbound mail, signed webhooks, replay, idempotency, versioned templates, automations, an MCP server, Markdown documentation — the two products answer the same way, and the honest summary is that this is a close comparison rather than a lopsided one.

The verdict

Two rows separate these products at the price list. Extra email costs $0.60 per thousand on Rasket and $0.90 on Resend, and broadcasts sit on the same Rasket plan and the same key as transactional mail, where Resend prices marketing email as a second plan. Everything else in the table is a tie or close to one, so the choice is usually about those two rows and about which SDK you need: pick Resend if your language is on their longer list or you want an SMTP relay, and Rasket if you would rather pay less per thousand and keep one plan for every kind of mail you send.

Frequently asked questions

Is Rasket a good alternative to Resend?

Yes, on the rows the table covers. Both send over a REST API, sign their webhooks, receive inbound mail and document themselves for agents. Rasket charges $0.60 per thousand extra emails against $0.90, and keeps broadcasts on the same plan as transactional mail rather than pricing them separately. Resend has more SDK languages and an SMTP relay, so check those two rows before you move.

Does Resend include inbound email?

Resend: Yes. The pricing page lists inbound emails under "All plans include". Rasket receives mail at your own domain on every plan, including the free one, and delivers each message to a signed webhook with its headers, text, HTML and attachments.

Which is cheaper at 50,000 emails a month?

At exactly 50,000 emails a month the two entry plans cost the same: $20, for 50,000 emails, on both. The difference shows up past the quota — an extra thousand emails is $0.60 on Rasket and $0.90 on Resend — and again if you send marketing email, which Resend prices as a separate plan and Rasket includes on the one you already have.

Does Rasket have an SMTP relay?

No. Rasket sends over the REST API, the Node and Python SDKs, and the MCP server, and there is no relay to point a mail client or an off-the-shelf application at. If moving means changing an SMTP host rather than changing code, that is a real reason to stay where you are.

Can I migrate from Resend to Rasket?

Verify your domain in Rasket and publish the DKIM, SPF and DMARC records we generate, then point your code at POST /emails and swap the key. Templates are rewritten once and published as a version; contacts import from a CSV; each webhook endpoint is recreated with a new signing secret and can be replayed from the dashboard while you get the handler right. You can run both providers at once during the switch, because nothing about a verified domain is exclusive.

Which is better for AI agents?

Both are built for them, and it would be misleading to claim otherwise. Resend publishes an MCP server, agent skills and Markdown at every documentation URL; Rasket publishes an MCP server with seven toolsets, a setup skill, Markdown at every docs URL, llms.txt and llms-full.txt. The practical difference is scope rather than tooling: a Rasket agent can set up a domain, send, receive and run a broadcast against one key.
