Notix is the closest Resend alternative in shape: a free tier of the same kind (5,000 emails a month to Resend's 3,000, 200 a day, no card), the same JSON send call, SMTP on every plan. It is $15 a month instead of $20 at the 50,000-email line, adds an OTP API and a pre-send deliverability check, states a 99.9% SLA on Pro, and bills in naira or shillings from a prepaid wallet. Teams that live in React Email or need SDKs in nine languages should stay on Resend; Notix ships four. Everyone else can move in an afternoon.
Resend's pricing page moves you from a 3,000-a-month free plan straight to Pro at $20 a month for 50,000. For a product sending 5,000 receipts a month, that is $20 for capacity it will not use, and the free plan's single domain rules out separating transactional and marketing mail.
Resend sends the email; the one-time code, its expiry and the check are yours to build. Its send endpoint has no notion of a code, and there is no pre-send test for whether a message is likely to land. Teams building sign-in flows end up writing that layer themselves.
Resend bills in US dollars to a card. Teams in Nigeria and Kenya paying from a naira or shilling account, or without a card that clears international charges, cannot pay at all. Its knowledge base lists no local billing option.
Every Resend figure was read from Resend's own pages on 2026-09-12; the date sits under the table. If a number has changed since, the page is wrong and we would like to know.

Resend ships official SDKs for Node, Python, PHP, Ruby, Go, Java, Laravel, Rust and .NET; Notix ships TypeScript, Python, Go and PHP, and everything else uses the JSON endpoint. If your stack is Ruby, Java, Rust or .NET and you want a typed client, Resend has one today and Notix does not. Resend also built React Email, and its documentation and examples assume it everywhere, which is a real convenience for a React team. Finally, Resend is the better-known name: more tutorials, more Stack Overflow answers, more templates. None of that changes what your mail does, but it shortens the search when something breaks.
Both send through a JSON API with an idempotency key, both offer SMTP on the free plan, both sign webhooks, and both run on the same underlying model of a sending platform in front of cloud infrastructure. For a plain transactional send, the two calls are interchangeable; the migration section below shows how little changes.
One call sends a code by email or SMS, one call checks it. Expiry, attempts and rate limits are handled server-side. See the transactional email API.
Post the message and get back a spam score, missing headers and domain problems before a single recipient sees it.
Bounces, complaints and unsubscribes suppress across transactional and marketing mail, so a receipt never goes to an address that bounced a campaign.
The uptime commitment and its service credits are written on the pricing page, not in a sales conversation.
A prepaid wallet in NGN or KES, topped up locally. Pro is charged from the balance each month; no dollar card needed.
The send call has the same fields. Swap the client, swap the key, verify your domain, and the rest of your code stays as it is.
import { Resend } from "resend";
const resend = new Resend(process.env.RESEND_API_KEY);
const { data, error } = await resend.emails.send({
from: "receipts@acme.com",
to: "customer@example.com",
subject: "Your receipt",
html: "<p>Thanks for your order.</p>",
});
import { Notix } from "notix-js";
const notix = new Notix(process.env.NOTIX_API_KEY);
const { data, error } = await notix.emails.send({
from: "receipts@acme.com",
to: "customer@example.com",
subject: "Your receipt",
html: "<p>Thanks for your order.</p>",
});

Add the SPF, DKIM and DMARC records Notix gives you. They sit beside Resend's records, so both services can send while you switch. The quickstart walks through it.
Replace the resend package with notix-js and the key in your environment. If you send over SMTP, change the host and credentials as shown above; the SMTP relay takes the same message your mailer already builds.
Export the addresses Resend has marked bounced or complained and upload the CSV under Suppressions in the dashboard, so the first sends from Notix never reach an address that has already said no. Webhook URLs move last, once traffic has.
| Emails a month | Resend | Notix |
|---|---|---|
| 10,000 | Pro, $20 (Free stops at 3,000) | Pro, $15 (Free stops at 5,000) |
| 50,000 | Pro, $20 | Pro, $15 |
| 100,000 | Next tier; see resend.com/pricing | Pro, $15 plus the 50,000 above the allowance, metered on the same invoice |
Both free plans cover the same first 3,000 emails at $0. At 10,000 and 50,000 the difference is $5 a month. At 100,000 Resend moves you to a larger plan, while Notix keeps you on Pro and adds the overage to the same invoice at the per-unit rate on the pricing page, where you can run the estimate for your own volume. Prices read on 2026-09-12.
Teams in Nigeria and Kenya fund a prepaid wallet in naira or shillings through local payment methods and Pro is charged from that balance each month, so nobody needs a dollar card that clears international charges. The free plan is the same everywhere. The local price per email is on the pricing page when you open it from either country, and every invoice and receipt is in the wallet currency.
