Nurturing and contacting previous prospects

Yes, you can contact prospects from earlier campaigns again. Go to Settings in the sidebar, open the Company tab, and find Nurturing. There are three settings:

• Re-contact non-responders after: how long to wait before contacting someone who never replied (from 1 to 18 months, or Never).
• Re-contact responders after: how long to wait before contacting someone who did reply (from 3 to 18 months, or Never).
• Contact other people at a company that already responded after: how long to wait before contacting colleagues of someone who replied.

Your exclusion lists and CRM rules always apply first, so excluded companies and contacts are never re-contacted.

To give returning prospects a different message, create a nurture sequence.
