Email Signature for Software Developers

Software developers tend to prefer the shortest signature that does the job, and the conventions of developer email back that up. A typical developer signature carries the name, role, and company, and a link to the developer's GitHub, GitLab, or personal site, which says more about their work than a job title. Developers who contribute to open source often add a link to a project they maintain. Mailing lists, which many open source projects still use for discussion and patch review, expect plain text, and the long-standing convention is to separate the signature from the message with a line containing two hyphens and a space, so mail clients and list software can recognize and strip it. Netiquette guidance from the same era suggests keeping a plain-text signature to about four lines. Developers who sign mail cryptographically include a PGP key fingerprint or a link to their public key. Freelance developers and consultants add a portfolio link and availability. Developer relations teams are the exception to minimalism: they carry links to documentation, a community forum, or an upcoming talk, and often use banners for developer events.
