Hi @Beeeman , in the Samsung e mail application the only real option is to Mark as Spam, thus future emails from unwanted sources should go straight to the Spam folder and can be deleted in bulk from there. However sometimes the filter does not work as intend,best to check the senders in case any trusted ones end up there. To delete in bulk see here https://deletingsolutions.com/how-do-you-mass-delete-emails-on-samsung-galaxy/
Gmail has a Mute option but similar as the emails will still be contained in a Folder. https://support.google.com/a/users/answer/9308777?hl=en Users are also able to Report Spam but whether that will result in desired action another matter.
