Overwhelmed by the number of unnecessary subscriptions clogging your inbox? Sign up for “Unroll Me,” which is a service that combs through your inbox and suggests emails to unsubscribe from in bulk.
\You can also add “+spam” to the end of your email address when you’re required to provide an email, and all mail from them will go directly to your spam folder.
Enable the “Undo Send” feature on your Gmail account. Go to Settings, click the General tab, and scroll down to the option for your preferred cancellation period. After you send an email, look in the bottom left corner to see the option to undo send.
