If you're no longer interested in using specific Google services, such as Gmail or YouTube, you can sign in to your Google Account to delete them. You can even delete your entire account and all your data, such as emails and photos.

The easiest might be to Google the name of the service, followed by "delete account". Countless how-tos will pop up that you can follow. Sites like JustDelete.me contain a cache of deletion instructions for various accounts, and contacting customer support – via chat or even phone – is always an option.

When you delete an email account, your messages typically don't disappear right away. Instead, most service providers wait a certain amount of time before honoring the mailbox deletion request. They do this to give users some time to change their mind and stop the deletion process before it's too late.
