Why limits?
Tinnbox is not a bulk email service.
We intentionally limit daily outgoing emails to:
- protect deliverability
- prevent abuse
- keep inbox reputation clean
- ensure long-term reliability
Most people don’t send more than 5–10 emails per day anyway.
What happens when I hit the limit?
Sending is soft-blocked — no penalty, no account risk. Limit resets automatically the next day. You can upgrade instantly if needed.
