Hi Kevin
Try these steps:
- Create a new custom field for Sales Email.
- Everytime any lead receives the sales email from ou team, update the value of this custom field to YES.
- Now in your smart campaign, go to Flow and select "Remove from Flow" as an action.
- In the pop up for removing the lead, click on Add Choice.
- From the IF drop down, select Sales Email custom field and add the condition for that.
- In the next step, you can select the smart campaign from which you want to remove the lead.
Let me know if this works out you.
Regards
Alok
