jdavidbakr/mail-tracker[6.0, ..., 6.0.2] require illuminate/support ~9.0 -> found illuminate/support[v9.0.0-beta.1, ..., 9.x-dev] but these were not loaded, likely because it conflicts with another require.

Other packages with the same requirement "require illuminate/support ~9.0" are installed and working.
For Laravel < 9 you need to use version 5.*. There was a fundamental change in Laravel 9 that completely changed the way it sends mail, and this package had to be rewritten for Laravel >= 9.
Your requirements could not be resolved to an installable set of packages.
