Two of your clients just emailed the same person
Agencies and big sales teams share lists. Without guard rails, the same lead hears from you twice in a week.

How do I stop several brands contacting the same lead?
In Super Intelligent Sender, a lead contacted by one brand is locked from every other brand in the workspace for 90 days. After one person at a company is emailed, the rest of that company waits 24 hours. Frequency caps and cross-campaign cooldowns stop the same lead being emailed by two campaigns back to back, and a lead already in a campaign is skipped at import.
Signs you have this problem
- A prospect replies "your colleague already emailed me"
- Two clients' campaigns target the same company in the same week
- The same person is enrolled twice from two CSV files
- Five people at one company get the same email on the same morning
