Our flow open rates dropped from 55% to 36% January to February.
Unsubscribe, spam and bounce rates are all rated good/excellent in the past couple of months, so reputation hasn’t been affected by an increase in these.
I have however been running multiple A/B tests on the core flows to try increase open rates (Welcome, Cart & Checkout Abandon, Browse Abandon, New & Repeat Customer). I’m wondering if running all these tests at the same time has had a negative impact on deliverability which has led to this huge drop in open rates?
It should be noted that campaign open rates remain healthy at around 50% while sending to a 30 day engaged audience of over 200,000 profiles, 2-3 times per week. So I’m confused how the deliverability of campaigns looks so good but flows have had this sudden fall.
Does anyone have any ideas in the sudden drop in flow open rates/ anyone seen something similar?
Any help would be greatly appreciated. Thank you.
