Ran a pilot test in CI Journey this week. The segment was set up and correctly added, 50,242 records. The Journey was setup and went through like a charm but it stopped at 48,610. So I am short 1,632 emails. I can download/extract the 50,242 contacts in the segment but have no way of extracting the 48,610 sent emails to try and reconcile which contacts did not receive the email. This was done in the Real Time Journey. All contacts have unique and valid email addresses, all have /allow/ emails to this transactional email. I am baffled on why it did not send out all of the email messages but also stumped that I can not easily (or figure out) how to export the records/contacts that RT Marketing sent the messages to.
The journey is simple. Use the segment, and send an email out. The emails went out, but the /inflows/ did not bring in the total number of contacts that the Segment collected.
