Journey sending multiple email to same contact

(1) ShareShare
ReportReport
Posted on by 15
Hello, 
 
I have a real-time marketing journey configured as a one-time journey, where newly added audience members can start at any time.
Recently, I’ve noticed that some contacts are receiving the same email two or three times, often with identical timestamps. I’ve confirmed that these emails were indeed received multiple times by the same contact.
I first noticed the issue about two weeks ago. To address it, I created a specific segment that excludes contacts who have already received the email. However, the problem continues.
In the analytics section, I can see that this issue has been occurring since the journey was launched. It’s important to note that this is the only journey we have where new audience members can enter at any time. All our other journeys are working correctly and do not send multiple emails to the same contact.

Do you have any idea what might be causing this issue?
Is there a known bug related to this type of journey configuration?

Thank you for your assistance.

    Hello everyone!

    I resolved my problem and wanted to share my solution in case someone else is experiencing the same issue.

    Instead of having one journey with four branches, I created four separate journeys, each with one branch and one audience (segment). Since I started these journeys almost two weeks ago, I haven’t seen any duplicates!

    I still believe there’s a bug because I don’t think a contact should receive the same email twice or even three times. However, this workaround has fixed the issue for now.

    Thanks, and have a great day everyone!

    Do you have feature switch "email deduplication" activated? This one should also ensure that your above problem is not happening anymore.

    Yes, I have it activated, but it didn’t solve the problem. From my understanding, that switch prevents two different contacts with the same email address from receiving the email message twice if both contacts are in the segment. That wasn’t my issue — a single contact was receiving multiple email messages.
