What is usesend.com?

useSend is an open-source platform for sending transactional and marketing emails. It uses Amazon SES as the sending infrastructure and layers its own API, SDKs and a visual email editor on top. Teams can self-host the platform or use the hosted offering, which handles up to 3,000 emails per month for free.

The project targets teams that want to integrate email sending into their own products without depending on a proprietary service. The source code is publicly available, the pricing model charges per email sent, and contacts are not billed separately.

Core features

  • Transactional and marketing emails sent through a single platform, with separate workflows for automated system messages and manual campaigns
  • SDKs for TypeScript, Python, Go and PHP, plus an SMTP relay for existing applications that do not support direct API integration
  • Visual email editor for building templates without writing HTML
  • Contact management with lists, bounce handling and suppression lists
  • Self-hosting option for teams that want full control over their email infrastructure

Who is usesend.com for?

Developers and small teams sending password resets, order confirmations or newsletters who do not need an expensive all-in-one service. useSend is particularly useful when the contact base is large, since many competitors charge by contact count. Startups with irregular sending volumes benefit from the pay-per-use model.

The project is still young. Teams that rely on a mature community, extensive documentation and a broad set of integrations will not find those at the same level useSend currently offers compared to established services.

Context & alternatives

useSend sits in the transactional email category but also competes with marketing-oriented platforms. Comparable commercial services include Postmark, Resend and Brevo. In the open-source space, Listmonk is a well-known alternative, though it has no built-in sending infrastructure and no focus on transactional email.

The key difference from purely hosted services: because useSend can be self-hosted and connects directly to Amazon SES, the entire sending infrastructure can remain under the operator's own control. This requires an AWS account and assumes that SES is a good fit for the use case.
