Worked on the resend/react-email repository to enhance documentation quality and integration discoverability. Focused on improving the inbound integration documentation by removing stray '+' characters from the YAML frontmatter, which increased formatting validity and readability for future contributors. Updated the README file using Markdown to add MailerSend to the list of supported integrations, making it easier for developers to find and onboard with this provider. Emphasized technical writing and documentation hygiene, ensuring that changes were clearly traceable through co-authored commits. The work prioritized maintainability and developer efficiency, leveraging skills in documentation enhancement and collaborative workflows without introducing new bugs.
