A digital business card appended to the end of every outgoing electronic mail message can be a powerful tool for a programmer. It typically includes contact information, professional affiliations, and links to online portfolios or repositories of code. For instance, one might include a full name, job title (e.g., “Software Engineer”), company name, phone number, email address, links to a LinkedIn profile, GitHub repository, or personal website.
The consistent presentation of this information improves professional branding and makes it simpler for recipients to contact the sender or explore their qualifications. Its use eliminates the need to re-type contact details in every email. Over time, a well-designed version becomes an instantly recognizable identifier, fostering trust and reinforcing professional identity. Its implementation is a standard practice that dates back to the early days of email communication, evolving alongside email clients and software development practices.
