Validation in SFDC to prevent records synced from Marketo to Salesforce

[Anonymous]

Hi there,
I am running an email program to mass email X number of records, at this point in time these records shouldn't be synced to SFDC. How Can I build a validation to stop this? can this validtion be done through configuration in SFDC ?

Thanks,

Leads are only sent to SFDC if they go through one of the SFDC flow actions or if you are direclty tieing your Markeot program to an SFDC campaign.

How do you decide when Marketo leads should be created in SFDC?

You should have a central MQL processing flow that only pushes leads over when they meet the criteria Cathal suggests. Of course, if you link Programs-SFDC Campaigns, those leads sync no matter what.

Just sending an email should not sync those leads as long as the email program isn't linked to SFDC.
