useSend is an open-source, self-hostable email sending platform built on Amazon SES, offering transactional and marketing email delivery with a dashboard, REST API, SDKs, and SMTP relay. It serves as an open alternative to Resend, SendGrid, Postmark, and Mailgun, including contact management, campaign editing, analytics, and suppression lists.

Use cases

  • send transactional emails from my app without vendor lock-in
  • self-host an alternative to SendGrid or Resend
  • send newsletters and marketing campaigns to a contact list
  • track email deliveries, opens, clicks, and bounces
  • send emails via SMTP relay from any framework
  • manage email contacts and subscription consent
  • monitor Amazon SES email sending with a dashboard

When to choose

  • you want an open-source, self-hosted email platform backed by Amazon SES
  • you need both transactional and marketing email in one tool
  • you want to avoid per-contact pricing of SaaS email providers
  • you need SMTP relay plus REST API and typed SDKs
  • you want real-time delivery analytics and suppression handling

When to avoid

  • you need inbound email processing (not yet supported)
  • you don't have or want an AWS account since it relies on Amazon SES
  • you need SMS, push, or WhatsApp sending (planned but not available)
  • you require a fully mature, battle-tested product as it is still in beta
  • you need a service with AGPL-unfriendly licensing terms for commercial embedding
