Limits and quotas
What your plan limits, what a limit stops, and the fixed sizes and rates every account shares.
Every plan sets a few limits. Reaching one stops the thing that would grow past it and nothing else, so your readers never notice. The numbers for your plan, and how much of each you have used, are under Settings > Billing. The fixed sizes and rates below apply to every plan.
What your plan limits
| Limit | Counted as |
|---|---|
| Subscribers | People on your list now |
| Sends this month | Marketing mail sent since the start of the month (UTC) |
| Sending domains | Domains you have added |
| Members | People who can sign in to your account |
| Uploaded themes | Themes you have uploaded |
| AI spend this month | What writing help has cost since the start of the month (UTC) |
Some features, such as custom domains and the API, are part of some plans and not others.
What a limit stops, and what it never stops
A limit stops a new import, a new send, a new AI call, or adding a domain, a member, or a theme, with a message that says which limit was reached.
A limit never stops:
- transactional mail, including mail already accepted
- unsubscribes and the preferences page
- tracked links, which always take the reader where they were going
- your public site
- your data, which is never deleted for being over a limit

Things to know
- Usage is counted from what actually happened, so the numbers on the Billing page match your logs.
- An account whose payment lapses is past due, then suspended after a grace period. A suspended account cannot send marketing mail; everything in the "never stops" list keeps working.
- Webhook endpoints are tried up to 8 times per event, and switched off after 15 failed deliveries in a row.
- The event log keeps 90 days.
