How to fix sending rate or daily quota
What to do when sends are throttled or the daily SES quota is exhausted.
You got Sending rate exceeded or Daily sending quota reached. This is the email system’s account cap, not your Lumail plan’s monthly limit.
- Throttling — too many sends per second. Transient. Slow down; Lumail will retry eligible mail.
- Daily quota — the 24-hour send ceiling was hit. Wait for the window to roll, or ask for a higher cap.
What to change
- Stop launching another full-list campaign on top of one already draining the quota.
- Let in-flight retries finish. Don’t hammer “Send” on the same campaign.
- If this is normal volume for you, email [email protected] with the org slug and approximate daily volume. We raise the provider cap; you cannot do it in DNS.
- If you also see monthly Lumail limit alerts, that’s a different ceiling — How to fix a monthly email limit.
