Free email for open-source projects
Open source runs the software world. Emitlo gives a little back to the community by offering open-source projects free transactional email, with case-by-case sending limits.
Why Emitlo offers free email to open-source projects
Open-source projects are often maintained by volunteers, with no business model. Yet they need to send notifications, CI alerts and emails to their community. By offering our infrastructure, Emitlo helps these projects stay reliable and alive at no sending cost.
You use the same sending infrastructure as our paying customers: REST API and SMTP relay, double DKIM signing, automatic SPF/DKIM/DMARC setup, EU hosting compliant with GDPR, webhooks and a real-time deliverability dashboard.
What the program includes
- ✓Case-by-case sending limits — matched to your project's activity.
- ✓Fits CI/CD, notifications and community emails.
- ✓API and SMTP ready to use — integration in minutes.
- ✓EU hosting, GDPR compliant — email content is not retained.
- ✓Full authentication — DKIM, SPF and DMARC configured automatically.
