A reliable self-hosted email serverfor five dollars a month.
Open-source email infrastructure that runs on Cloudflare. Deploy it yourself, or have us run it for you.
The centralized inbox for SaaS teams.
Most teams send customers three different kinds of email — marketing blasts, transactional notifications, and support threads — and each one lives in a different tool. When a customer replies, nobody has the full picture.
SaaSmail collapses all of it into one timeline per person. Anyone on your team can open a customer and see every promo, every receipt, and every support reply in order. Context compounds. Replies get better.
SaaSmail is built and maintained by XY Space as an open-source project. The code lives on GitHub, free for anyone to self-host — or we can run it for you.
Six things you'd otherwise pay a SaaS for.
One timeline per customer
Every email from a person — marketing, billing receipts, support replies — collapses into a single conversation. Open it and the full history is already there.
Multiple inboxes, one team
Run support@, sales@, and billing@ from one place. Decide which teammates see which inbox. Everyone stays in their lane without juggling tabs.
Thread or chat — your choice
Set each inbox to feel like classic email (subjects, quoted replies) or like a messaging app (bubbles, no signatures). Marketing reads as marketing; support feels like a chat.
Reusable email templates
Write a template once with simple {{placeholders}} for things like names. Preview it, then send from the dashboard or your own code.
Drip sequences
Enroll a customer in a multi-step email series — onboarding, follow-ups, re-engagement. The series cancels itself the moment they reply.
Team & API access
Invite teammates with one-time links and passwordless sign-in. Issue scoped API keys when you want another tool to send mail through SaaSmail.
Five dollars. A month. All in.
The only bill is Cloudflare's Workers Paid plan — $5/month — which includes 3,000 outbound emails. No server to rent, no per-seat fees, no separate database bill. Just a domain, a Cloudflare account, and the paid plan.
- Most help-desk tools: $20–$50 per teammate, per month.
- Most marketing platforms: $30+ per month, plus list-size fees.
- SaaSmail: a single $5 Cloudflare bill, unlimited teammates.
