### General
- You might want to consider the use of an e-mail filter, so as to e.g. automatically move the data export e-mails to a dedicated trakt-tv-data-exports folder.
- If you don't like the success toasts, you can turn them off by setting showToastOnSuccess to false in the userscript storage tab *(note: only displayed after first run)*, there you can
    also specify your own [cron expression](https://crontab.guru/examples.html). E-Mail data exports have a cooldown period of 24 hours, there is no point in going below that with your cron expression.
