Campaign Limits & Best Practices

4 min readUpdated 2026-04-12

Key Takeaway

Daily email limits are enforced by plan (Free: 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

  1. Be specific — Narrow target audiences get better response rates
  2. Set realistic goals — A 5-10% reply rate is excellent for cold outreach
  3. Monitor bounce rates — High bounces damage sender reputation
  4. 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
