Commit Together by Github VS Local Mail by Mailjoy

• Enhanced Collaboration
  Commit Together allows multiple authors to be credited in a single commit, which fosters a more collaborative environment and ensures everyone involved receives recognition for their contributions.
• Improved Code Review Process
  With multiple authors clearly listed, reviewers can better understand who contributed to which parts of the code, facilitating more directed questions and discussions.
• Accountability
  By attributing every change to the respective author, teams can easily track who made specific changes, which helps in accountability and understanding the history of a project.
• Efficiency in Pair Programming
  When pair programming, both developers can be credited for their combined effort, streamlining the process of sharing code ownership during collaborative sessions.

Possible disadvantages

• Complex Commit History
  Having multiple authors for a single commit may lead to a more complex commit history, making it harder to pinpoint individual contributions over time.
• Potential Workflow Conflicts
  Teams that are used to single-author commits may experience workflow conflicts or require adjustments in practices to accommodate multi-author contributions.
• Initial Setup Overhead
  Learners and new users might face a learning curve or require additional setup to understand and correctly implement the multi-author commit feature.
• Tooling Compatibility
  Some third-party tools and extensions might not fully support or display multi-author commits, leading to inconsistencies in those environments.

• Free design templates
  Many design templates, and you can customize any of them to make the design your own.
• Powerful, easy to use designer
  No need to hire a designer or use expensive software.
• Precisely target local markets
  No mailing list required! Instead, select zip codes or postal routes you want to target. We even provide demographic data on each route to help you narrow your targeting.
• Track your campaign's progress
  Skip the headache of visiting the post office. When your campaign is complete, simply checkout. Within 6-10 business days your campaign will reach recipients. You can track its progress through Mailjoy.
• Target based on demographics
  If your product targets certain demographics, use Local Mail's route data to help you find postal delivery routes with your ideal customers.
• Scalable, transparent pricing
  No pricing surprises. Our mailer costs include print and postage. The more you send, the lower your cost per mailer.
• Lightning fast turnaround
  Your campaign is shipped within days of placing it. Mailers will reach your recipients’ mailbox in 6-8 business days.
• Full color mailers
  We only print high quality, full color postcards. You have full design control over the front and back. Local mail is only available in 11” x 6”.
• Low minimum campaign size
  Send local mail campaigns with as little as 500 recipients. This can be from routes in multiple zip codes across the country.

• Ask HN: Do you rewrite pull requests?

  There is "Co-authored-by" which is supported on GitHub [1] and seems appropriate if the maintainer is basing the solution on someone's code. [1] https://github.blog/2018-01-29-commit-together-with-co-authors/. - Source: Hacker News / over 4 years ago
