How this estimate works
Users × emails kept per day × 365 × years × average stored email size. We use 1 KB = 1,024 bytes and 1 GB = 1,024³ bytes to match FranklyMail mailbox quotas. Existing archives, growth and deleted-mail retention are not added automatically. Leave room for them in your inputs.
