Does archive mail count towards usage in fastmail

According to FastMail's documentation, archived emails do not count towards your email storage usage.

Here's a quote from their help article on "Archiving emails":

"When you archive an email, it's moved to a special folder that's not included in your storage quota. This means that archived emails don't count towards your storage limit, and you can keep as many as you like without worrying about running out of space."

So, if you're using FastMail and you're concerned about running out of storage space, archiving your emails is a great way to free up space without having to delete them.
