In the past couple of months I noticed a hard fall in revenue from Klaviyo flows.

After trying dozens of changes in copy, marketing strategy, timing, etc, I just noticed that every time I started a flow from scratch, instead of turning the statuses of the older ones to “draft”, I was turning it to “manual’. Right now this is an example of how it looks like, and only because I turned a lot already to draft since I read this article.

When I opened those older flows set to manual, I found that there were thousands of emails queued as “Needs Review”, and a. bunch of new emails still being queued as “waiting” as of today. I have flows that the last email (hence the date the status was changed to “manual”) were delivered for the last time in September, however people were still being scheduled to receive an email for future dates, like tomorrow.

My question is: would this prevent all these people stuck in “Needs Review” from entering the actual live flows? I am wondering if after all that is the reason for the steep decrease in revenue from flows.

I am able to cancel the “Needs Review” in bulk, however, the “waiting” only gives me the option to cancel one by one. After turning the entire flow to draft, do I still need to cancel the emails in “waiting” status as well? If so, is there a way to bulk cancel those just like the ones in “Needs Review”?

Thanks.
