Mailgun Basic and Notix Pro both cost $15 a month. Basic includes 10,000 emails; Notix Pro includes 50,000, adds an OTP API and a pre-send deliverability check, keeps one suppression list across transactional and marketing mail, and bills in naira or shillings from a prepaid wallet. Teams that rely on Mailgun's inbound routing and parsing, its bulk address validation, or the wider Sinch messaging bundle should stay; Notix does none of those. For a team that sends and wants more room for the money, the move takes an afternoon.
Mailgun's pricing page puts Basic at $15 a month for 10,000 emails, Foundation at $35 for 50,000 and Scale at $90 for 100,000. A product that sends 20,000 receipts a month sits on Foundation, paying for capacity it does not use, and every step up is a plan change rather than a metered overage.
On Basic, address validation is an add-on at $1.80 per 1,000 checks, and longer log retention arrives with the higher plans. The features a small team reaches for first are the ones priced separately, which is how a $15 line item becomes $35 or $90 before the volume needs it.
Mailgun is a delivery API. The one-time code for a sign-in flow, its expiry and the check are yours to build, and there is no pre-send test for whether a message is likely to land. Transactional and marketing mail live in separate products with separate suppression, so a receipt can go to an address that already bounced a campaign.

Mailgun receives mail as well as sending it: inbound routes accept messages for your domain, parse them into fields and attachments, and post them to your application. Notix has no inbound routing. Mailgun also sells email validation as a product, checking a list of addresses before you send to it, with 5,000 checks a month included from Foundation; Notix scores individual verification requests but does not clean lists. Higher Mailgun plans offer longer log retention, and Scale adds dedicated IP pools with the tooling to manage them. If any of those is on your critical path, Mailgun is the right tool and this page is not for you.
Both send through a JSON API, both offer an SMTP relay on every plan including free, both sign webhooks for delivery events, and both verify a sending domain with SPF, DKIM and DMARC records you add once. For a plain transactional send the two calls carry the same fields; the migration section shows how little changes.
Pro includes 50,000 emails a month. Past that, the extra is metered on the same invoice rather than through a plan change; the pricing page has the per-unit rate.
One call sends a code by email or SMS, one call checks it. Expiry, attempts and rate limits are handled server-side. See OTP email.
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 in one account, with the marketing side (contact books, campaigns, double opt-in) included rather than sold separately.
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 carries the same fields. Swap the client and the key, or the SMTP host, verify your domain, and the rest of your code stays as it is.
import formData from "form-data";
import Mailgun from "mailgun.js";
const mailgun = new Mailgun(formData);
const mg = mailgun.client({ username: "api", key: process.env.MAILGUN_API_KEY });
const result = await mg.messages.create("mg.acme.com", {
from: "receipts@mg.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);

# Before
SMTP_HOST=smtp.mailgun.org
SMTP_PORT=587
SMTP_USER=postmaster@mg.acme.com
SMTP_PASS=<Mailgun SMTP password>

SMTP_PORT=465 # or 587 for STARTTLS
SMTP_USER=notix
SMTP_PASS=<your Notix API key>
Add the SPF, DKIM and DMARC records Notix gives you. They sit beside Mailgun's records, so both services can send while you switch, and any inbound MX records you keep on Mailgun are untouched. The quickstart walks through it.
Replace mailgun.js with notix-js and the key in your environment; the domain argument goes away because the sender address carries it. Over SMTP, point your mailer at smtp.usenotix.dev on 465 or 587 with user notix and your API key as the password; the SMTP relay takes the message your mailer already builds.
Export Mailgun's bounces, complaints and unsubscribes, save them as a .csv or .txt with one address per line, and upload the file 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 | Mailgun | Notix |
|---|---|---|
| 10,000 | Basic, $15 (Free stops at 100 a day) | Pro, $15 (Free stops at 5,000) |
| 50,000 | Foundation, $35 | Pro, $15 |
| 100,000 | Scale, $90 | Pro, $15 plus the 50,000 above the allowance, metered on the same invoice |
At 10,000 the two cost the same. At 50,000 Mailgun needs Foundation at $35 while Notix stays on Pro at $15. At 100,000 Mailgun moves to Scale at $90; 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. Mailgun prices read on 2026-09-13.
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 receipt is in the wallet currency.
