Problem
Developers and product teams face significant friction when sending transactional emails, including poor documentation, unpredictable pricing, rate limits that don't scale, and deliverability that feels like a black box. This makes it difficult to reliably deliver critical messages like password resets, order confirmations, and verification codes, especially at scale.
Solution
Unosend provides a developer-first email API that simplifies sending transactional emails through a single HTTP request or SMTP, with a focus on speed, reliability, and transparency. The platform runs on dedicated sending infrastructure with per-domain DKIM signing to ensure high deliverability, and it offers multi-region deployment across Asia and Europe for low-latency global reach. Developers can send critical emails in under 3 seconds, track delivery through deep logs, and monitor performance via a powerful dashboard. Unosend's credit-based pricing model eliminates subscription commitments, allowing teams to pay only for what they use while accessing clean SDKs and comprehensive documentation.
