Pigeon Atlas, Mail That Keeps Its Lanes
An HTTP API and SMTP endpoint for application email, with domain-level DKIM signing, separate transactional and bulk delivery, and searchable message archives.
Field notes
Pigeon Atlas exposes both an HTTP API and an SMTP endpoint, with requests shaped to match Resend’s format. Its stated delivery model separates bulk and transactional mail, checks hard bounces and complaints before queuing, and archives sent messages with recipient-level history. The homepage offers ten messages without a card for verifying a domain and watching a message arrive, while migration material specifically calls out transferring an existing suppression list.
