Notix vs Brevo.

Brevo is a marketing suite with a transactional email API attached: contacts, automation, SMS, WhatsApp, chat and a CRM, with a free plan of 300 emails a day across all of it. Notix is a developer email API with marketing features attached: a JSON send with an idempotency key, signed webhooks, an OTP API, a pre-send deliverability check, a 99.9% SLA, and 50,000 emails for $15. The right one depends on whether email is the product you are buying or one channel inside a bigger one.

Pricing.

Brevo's free plan is 300 emails a day once the account is approved for sending, with the API, the SMTP relay and webhooks included. Starter is $9 a month for 5,000 emails ($8 on the yearly plan) and Standard $18 ($16 yearly), with Professional from 150,000 emails and Enterprise above. Notix Free is 5,000 emails a month and 200 a day with no card and no end date; Pro is $15 for 50,000 emails, with usage past that metered on the same invoice at the rate on the pricing page. Brevo's free tier is larger; Notix's first paid plan includes ten times the volume of Brevo's.

Sending API.

Brevo's transactional endpoint takes HTML, plain text or a template id with parameters, and the same account sends marketing campaigns from the same contact list. Notix takes a JSON body with an idempotency key so a retry cannot double-deliver, has batch and scheduled sends on the same endpoint family, and its email API covers contacts, templates and campaigns under one key. Both expose an SMTP relay on every plan. A plain transactional send moves between them after a client swap.

Webhooks.

Brevo posts transactional events (sent, delivered, opened, clicked, soft and hard bounce, complaint, blocked, error) to your URL and recommends an allowlist of its IP addresses to keep strangers out. Notix signs each event with HMAC-SHA256 over the timestamp and the raw body, and rejects replays older than five minutes; the verification page has the check in four languages. Both cover the same event set for email.

Deliverability tooling.

Brevo offers dedicated IPs as a paid add-on on Professional and Enterprise and a mailbox-provider dashboard for campaign performance. Notix has a deliverability check you call before a send, which returns a score and the findings that would block delivery, and a suppression list shared across transactional and marketing mail. The transactional email API page describes both. Both verify domains with SPF, DKIM and DMARC and report bounces and complaints.

Marketing and everything else.

This is where Brevo is the larger product. Beyond email it sells marketing automation, landing pages and forms, SMS and WhatsApp campaigns, live chat, a sales CRM and meeting scheduling, and its free plan reaches all of it. Notix has contact books with double opt-in, a template editor, campaigns and journeys for email, on the same suppression list as transactional sends, and SMS in Nigeria and Kenya. If you want one vendor for marketing across channels, Brevo is built for that and Notix is not.

SDKs.

Brevo's developer documentation lists official SDKs for Node.js, Python and PHP. Notix publishes TypeScript, Python, Go and PHP, and everything else uses the JSON endpoint with a plain HTTP client, as the docs show for curl. Go teams get a typed client from Notix and not from Brevo; for Node, Python and PHP the two are interchangeable in shape.

One-time codes.

Brevo's transactional API delivers the message you compose, so a sign-in or verification code means generating it, storing it with an expiry, counting attempts and rate-limiting the sender in your own code. Notix has a verification API that does all of that in two calls, by email or by SMS, with risk scoring before anything goes out. For a product that signs users in by code, this is the largest single difference between the two.

Billing regions and SLA.

Brevo's billing currencies and any uptime commitment are not stated on the parts of its site that could be read; custom SLAs are offered on Enterprise. Notix bills in US dollars by card and additionally lets teams in Nigeria and Kenya fund a prepaid wallet in naira or shillings, from which Pro is charged each month, and states a 99.9 percent uptime commitment on Pro with the credit schedule on the pricing page.

FAQ

Questions this comparison gets asked.

Is Notix cheaper than Brevo?

On the free side Brevo is the more generous: 300 emails a day, which is about 9,000 a month, against 5,000 a month and 200 a day on Notix. On paid plans it flips. Brevo's Starter is $9 a month for 5,000 emails and Standard $18; Notix Pro is $15 for 50,000 emails, with usage past that metered on the same invoice. If you send under 300 a day, Brevo costs nothing; if you send tens of thousands a month, Notix costs less.

Does Brevo have an OTP or verification code API?

No. Brevo sends the email or SMS you compose; generating, storing, expiring and checking a code are yours to build. Notix has a verification API that does all four in two calls, by email or SMS, with risk scoring on the request.

Are Brevo's webhooks signed?

Brevo's developer documentation lists the transactional events (sent, delivered, opened, clicked, soft and hard bounce, complaint, blocked and so on) and recommends restricting your endpoint to Brevo's IP addresses; it does not describe a signature. Notix signs every event with HMAC-SHA256 over the timestamp and the raw body and rejects replays older than five minutes, so a webhook receiver can verify the sender without maintaining an allowlist.

What does Brevo offer that Notix does not?

A great deal, outside transactional email. Brevo is a marketing platform: a contact database with segmentation, marketing automation, landing pages and forms, SMS and WhatsApp campaigns, live chat, a sales CRM and dedicated IPs as a paid add-on. Notix has contacts, templates, campaigns and journeys for email, and SMS in Nigeria and Kenya, but it is a developer email service first and does not try to be a CRM or a chat tool.

Which one publishes an SLA?

Notix states a 99.9% monthly uptime commitment on Pro, with service credits set out on the pricing page. Brevo's pricing page does not state an uptime commitment for its self-serve plans; if you need one in writing, ask Brevo's sales team about Enterprise terms.

Can I move from Brevo to Notix?

For the transactional part, yes, in an afternoon: the send call is a JSON body with a template id and variables on both sides, the SMTP relay swap is a host and a credential, and Notix imports a suppression list so hard bounces and complaints carry over. Marketing automation built in Brevo's editor has no export into Notix journeys and has to be rebuilt.
