Can I migrate from Resend to Sendhiiv without rewriting my code?

Mostly. Sendhiiv's send API uses the same from, to, subject and html fields as Resend, so you change the endpoint URL and API key and update the call. If you use SMTP, you simply swap the SMTP host and credentials — no code change at all.

What does Sendhiiv offer that Resend doesn't?

Built-in receiving mailboxes with webmail (not just inbound parsing), true pay-as-you-go billing with credits that never expire, lower prices at volume, and local-currency billing. Sendhiiv also runs on dedicated, monitored sending infrastructure.

Sendhiiv vs Resend

Q: Is Sendhiiv cheaper than Resend?

Yes, at most volumes. Sendhiiv's Starter is $9/month for 50,000 emails versus Resend's $20 Pro for the same volume, and Sendhiiv's pay-as-you-go rate of $0.20 per 1,000 emails undercuts Resend's overage rates of roughly $0.46–$0.90 per 1,000. Resend's free tier matches Sendhiiv's 3,000/month but caps you at 100 emails per day.

Q: Do both support SPF, DKIM and DMARC?

Yes. Both guide you through SPF, DKIM and DMARC setup when you add a domain. You can test any domain's records for free with Sendhiiv's SPF/DKIM/DMARC checker.

The verdict: Sendhiiv is the cheaper, more complete alternative to Resend — lower prices at every volume, true pay-as-you-go with credits that never expire, and built-in receiving mailboxes Resend doesn't offer. And because the API uses the same fields as Resend, switching takes minutes, not a rewrite. If you're paying Resend's prices for outbound-only email, Sendhiiv does more for less.

Why developers switch from Resend

Cost at volume. The gap widens as you grow. At 50k/month you pay $9 instead of $20; at half a million a month Sendhiiv is a flat $79 while Resend's Scale pricing climbs with volume. For spiky or low senders, pay-as-you-go at $0.20 per 1,000 with credits that never expire beats paying for a monthly tier you don't fill.

A real inbox, not just an API. Sendhiiv gives you actual receiving mailboxes with webmail, so you can send and receive on your domain without bolting on a separate provider. Resend focuses on outbound and inbound parsing.

No daily handcuffs on free. Resend's free tier caps you at 100 emails/day; Sendhiiv's free 3,000/month has no daily ceiling, so a launch-day spike won't stall.

What to know before you switch

Resend is a polished product with great tooling — if your stack is built around React Email, that ecosystem is genuinely good. Sendhiiv's bet is different: the same easy API at a lower price, with pay-as-you-go billing and a built-in inbox. For most teams sending transactional email, that combination wins on cost and flexibility — without giving up the developer experience you're used to.

Migrating from Resend takes minutes

Sendhiiv's send API uses the same from, to, subject and html fields as Resend — so migration is an endpoint and key swap, not a rewrite.

Before — Resend

// POST https://api.resend.com/emails
const res = await fetch("https://api.resend.com/emails", {
  method: "POST",
  headers: {
    Authorization: "Bearer re_xxxxxxxx",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    from: "Acme <hello@yourdomain.com>",
    to: "user@example.com",
    subject: "Welcome aboard",
    html: "<p>Thanks for signing up!</p>",
  }),
});

After — Sendhiiv

// POST https://api.sendhiiv.com/api/v1/messages — same fields
const res = await fetch("https://api.sendhiiv.com/api/v1/messages", {
  method: "POST",
  headers: {
    Authorization: "Bearer shv_xxxxxxxx",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    from: "Acme <hello@yourdomain.com>",
    to: "user@example.com",
    subject: "Welcome aboard",
    html: "<p>Thanks for signing up!</p>",
  }),
});

On SMTP? It's even simpler — point your SMTP host and credentials at Sendhiiv and ship zero code changes. Before you move, run your domain through our free SPF/DKIM/DMARC checker so authentication is green from day one.
