Unlimited storage — never delete mail to make room

The Business Email mailbox has no size cap.

You can keep every message, every attachment and years of history without ever hitting a limit. That means: - No clearing out old mail to free up space - No being prompted to upgrade for more room - A complete, searchable archive of your correspondence, kept indefinitely

This is one mailbox with genuinely unlimited storage — you never have to manage space or worry about running out.
