Every limit by plan
The complete list of what each plan allows. Only the three allowances at the top change what you pay; everything else is a safety net that normal use never reaches. For what happens when you hit one, see Plans and limits.

The three you are billed on
Store size
Things you set up
Storage and history
Assistant attachments is how much one message to the dashboard assistant can carry in images and PDFs. Import history is how long a finished import is kept, with the spreadsheet it ran on; what the import created is never removed with it.
Developer limits
Per-minute numbers are for your whole account, not per key. See Rate limits. The emails-per-customer cap is a protection so a misconfigured flow cannot mail one person forty times.
