Plans and what counts toward your limit
The four Mailbo plans and what each includes.

What counts toward your limit
- Contacts — the number of people stored in your workspace. Unsubscribed contacts are kept for your records; check your plan card for how usage is counted.
- Emails — on Free, you have a monthly send cap; paid plans are unlimited.
Your current usage (contacts and emails sent this month) is shown at the top of the Billing page.
