v0.6.70 · 2d ago
Open-source platform for running cold email campaigns from your own mailboxes, with warmup, a unified inbox, and CRM.
Why you might care
Aimed at sales and outreach teams that want self-hosted cold email without cloud dependencies, it runs on Docker with no AWS, GCP, or Stripe required. Warmup uses a pool of monitored mailboxes, and outbound mail goes through each mailbox's own provider so throughput scales by adding Go workers.
