Email that's truly yours
Mailmark was built out of frustration with paying three different services to host email, send campaigns, and manage inboxes. There had to be a better way.
- All-in-one
- Hosting, inbox & campaigns
- Custom domains
- you@yourcompany.com
- Open source
- Transparent & extensible
- Self-hostable
- Your data, your server
Our story
Mailmark started in 2024 as a solo project born out of frustration with fragmented email tooling. After juggling Google Workspace, Postmark, Mailchimp, and half a dozen other tools just to send an email from a custom domain, there had to be a better way.
The insight was simple: every business needs three things. A professional email address (you@yourcompany.com), a way to read and send email, and a way to reach customers at scale. These should not require three subscriptions, three dashboards, and three support teams.
Mailmark is still early and growing. It's an open-source, indie project focused on getting the fundamentals right before chasing scale. If you value transparency and simplicity, you're in the right place.

Founder & Solo Developer
Full-stack developer who got tired of paying for three separate services just to send email from a custom domain. Mailmark is the all-in-one platform he wished existed -- built with a focus on developer experience, deliverability, and transparent pricing.
What we stand for
Four principles that guide every decision we make.
Own your infrastructure
We believe businesses should own their email infrastructure. Your domain, your data, your rules. No vendor lock-in.
Simplicity first
DNS, SPF, DKIM. These shouldn't require a systems administrator to configure. We automate the hard parts so you can focus on communication.
Transparent pricing
No per-seat fees that punish growth. No surprise overages. You always know exactly what you're paying for and why.
Built for teams
Whether you're a solo founder or a 50-person team, Mailmark scales with you. Shared inboxes, permissions, and collaboration baked in from day one.
