## What it is
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
