Comparison
SendByte vs Postmark
Postmark is the deliverability benchmark for transactional email: it refuses marketing traffic to protect inbox placement, and that discipline shows. SendByte shares the same transactional-first philosophy and adds African hosting and Naira pricing on top.
The bottom line
If raw transactional deliverability is your single most important factor and you are fine paying in US dollars from a US-hosted platform, Postmark is excellent. If you send from Africa and want that same transactional discipline with Naira billing and African routing, SendByte is built for you.

Common questions
Does SendByte deliver as well as Postmark?
SendByte is transactional-first like Postmark, with suppression handling, reputation isolation, and inbox-placement checks. It runs on proven sending infrastructure in Africa and tunes specifically for African inboxes, where US-routed mail can be deprioritised.
Is SendByte a Postmark alternative for Nigeria?
Yes. It offers the same transactional discipline and a clean API and SMTP relay, but prices in Naira, bills via Paystack or Flutterwave, and hosts in Africa.
Can I keep my transactional and marketing email separate on SendByte?
SendByte focuses on transactional email, so your receipts, password resets, and OTPs are not sharing reputation with marketing blasts. That separation is part of what protects inbox placement.
Transactional email, priced in Naira and hosted in Africa.
The same REST API and SMTP relay, deliverability tuned for African inboxes, on a price that does not move when the Naira does.
