I have configured Journey Builder interaction named "Opportunity Interaction" which gets triggered on Opportunity creation in sales cloud. The salesforce data entry event injects Person Account and Opportunity Data into Journey. My requirement is Journey should send email to email id of Person Account records.
Earlier I was able to inject REAL TIME newly created Person Account into Journey with valid email and MC records the Contact source as "API". Hence, even these contacts not already in the MC, Journey interaction was able to send email to them.
However, currently Journey Builder sends email only to those contacts which are already exists in MC, and no more sending emails to newly created Accounts. Even if I go to check "Send Preview" of any email, and selects data extension(created by salesforce data entry event) the newly created record gets displayed as "Invalid Recipient" under Email Address column.
Could anyone please help me out to resolve this.
