Create a welcome sequence when someone makes their first contribution: Email 1 (day 0): Thank you for your contribution and celebration of their involvement. Email 2 (day 1): Point to contributor documentation and coding standards. Email 3 (day 3): Share tips for making successful pull requests and avoiding common pitfalls. Email 4 (day 7): Highlight other open issues they might want to tackle. Email 5 (day 30): Check in and offer mentorship if needed. Make new contributors feel welcomed, not scrutinized. Frame onboarding as helping them succeed, not gate-keeping.
Create separate release emails for users and for contributors. User release emails focus on new features, improvements, security fixes, and what they should upgrade. Include clear upgrade paths and links to documentation. Contributor release emails focus on internal implementation changes, refactoring, new tooling, and how the changes improve the codebase. Send release announcements to your general list, but tag user emails differently than contributor emails so you can segment future messaging appropriately.
Move fast but responsibly. Email security researchers who reported the issue confirming receipt and your timeline for a fix. Once you have a patch, email all users immediately with clear security advisory text, the vulnerability impact, CVE details if available, and exact instructions for updating. For major security issues, send multiple reminder emails to ensure notification. Be transparent about what happened and how you are preventing similar issues in future. The open source community values security transparency.
Varies by project size. Monthly community newsletters are standard. Weekly digests of merged pull requests and closed issues for active contributors. Immediate notifications for major releases and critical issues. Event announcements (hackathons, conferences, calls for papers). Let contributors control frequency through preference centers. Many open source contributors are volunteers, so respect their inbox. Make email valuable through quality community building, not frequency.
Create a monthly email highlighting top contributors from that month. Include a short bio and quote from the contributor about why they work on the project. Share contributor milestones like "first pull request," "100 contributions," or "1 year of contributing." Feature community projects built with your tool. Send birthday or anniversary emails to long-time contributors. Make recognition personal and genuine, not performative. Contributors work on open source for intrinsic motivation, so recognition matters deeply.
Announce breaking changes at least 6-12 months ahead with multiple email notices. Email 1 (6 months out): Announce planned change and rationale. Email 2 (3 months out): Share migration guide and ask for feedback. Email 3 (1 month out): Final notice with specific deprecation date. Email 4 (1 week out): Reminder that breaking change goes live soon. Email 5 (release day): Confirm breaking change is live and provide support. Open source communities can handle breaking changes if given clear notice, migration paths, and support.
