Campaign Limits & Best Practices
4 min readUpdated 2026-04-12
Key Takeaway
Daily email limits are enforced by plan (Trial: 10/day, Pro: 50/day, Ultra: 150/day); campaigns auto-pause if bounce rate exceeds 2% or spam complaints exceed 0.1%.
Rate Limits
| Limit | Value | Why |
|---|---|---|
| Max emails per day | 10-150 (varies by plan) | Protects sender reputation |
| Max bounce rate | 2% | Auto-pauses campaign if exceeded |
| Max spam complaint rate | 0.1% | Auto-pauses campaign if exceeded |
| Max follow-ups per lead | 1 | Respects recipient attention |
Best Practices
- Be specific: Narrow target audiences get better response rates
- Set realistic goals: A 5-10% reply rate is excellent for cold outreach
- Monitor bounce rates: High bounces damage sender reputation
- Review hot leads promptly: Respond within 24 hours for best conversion
Compliance
All campaigns automatically enforce:
- CAN-SPAM Act: Physical address, clear identity, one-click unsubscribe
- GDPR: Consent tracking, data export, right to deletion
- Email verification: All leads verified before sending
