Rate Limits Explained
Rate limits protect deliverability by preventing sudden spikes that could trigger spam filters. Limits are applied at the account level and shared across all your SMTP credentials and API keys.
| Limit Type | Scope | What Happens When Exceeded |
|---|---|---|
| Per-minute | Account-wide | 429 error; retry after 60 seconds |
| Per-hour | Account-wide | 429 error; retry after the hour resets |
| Per-day | Account-wide | 429 error; retry after midnight UTC |
| Per-month | Account-wide | 429 error; upgrade plan or wait for next month |
Cross-node sync: Rate limits are synchronized across all CyberMail nodes via UDP, so limits are enforced consistently regardless of which server handles your request.
Bounce Rate Auto-Suspension
To protect shared infrastructure reputation, accounts with excessive bounces are automatically suspended:
- Bounce rate threshold: 10% of sent emails in a 24-hour window
- Minimum sent: At least 50 emails must be sent before the threshold applies
- Consecutive bounces: 20 consecutive bounces triggers immediate suspension
If suspended, clean your mailing list and contact [email protected] to request reactivation.
