Target List Wizard

"Do you mean that you want to make sure a contact is only in one target list?"

Essentially yes.

From what I understand of SuiteCRM when Targets are converted to Leads they remain a Target and the record is copied to the Leads module and the records associated creating a conversion path.

If I build a marketing list that pulls data from both Targets and Leads I want to make sure that I don't have the same record twice and send duplicate emails or make duplicate calls etc.

How do I ensure this? (if could be that I have misunderstood something).

Regarding calls, I'm not sure but with emails, there will never be duplicate emails from campaigns. In a campaign, emails are never sent twice to the same email address. Now, there is something quite interesting in your question and we might think about that. A new feature would be the capability to automatically remove targets or leads from a target list when they are converted.

So expanding on that feature a little further.

From what I understand ......

1. Target Lists can feed Calls, so if a duplicate record is found in the Target List it will probably create duplicate Call activities.
2. Target Lists can also feed Campaigns for external marketing campaigns which could also result in duplicate records unless the external service automatically restricts this.
3. Also if I send Leads into SuiteCRM directly from an external Form I need a method to avoid duplication again.

From what you are saying this is not currently supported which would make maintaining effective or clean Target Lists quite a challenge. Unless of course, I have misunderstood some functionality of SuiteCRM or your Extension.
