Hi @bjwendroff,
Thanks for reaching out to the Community!
Based on what you’ve mentioned, that option is not currently available as a trigger in a workflow. If you have the email subject line, and if that email is only used in that sequence, you could potentially use the email replied trigger. Unfortunately, we don’t have options for when an action hasn’t occurred, such as setting up filters for when someone hasn’t replied to your email.
If you think this would be a valuable addition, I recommend submitting it to our ideas forum.
Best,
Diana
