Transitioning from SHA-1 to SHA-256 involves several steps:
Update systems and libraries: Ensure that your email marketing software and libraries support SHA-256. Reconfigure authentication protocols: Update configurations for DKIM, DMARC, and other authentication mechanisms to use SHA-256. Test thoroughly: Before going live, thoroughly test the new setup to ensure compatibility and functionality. Educate your team: Ensure that your email marketing team understands the importance of this transition and how to implement it.
