Hello,
From the past 2-3 weeks, we’ve observed that in our split test (for only subject lines), Test 2 & Test 3 gets 0% open rate. The tests are delivered to everyone evenly but only Test 1 gets any opens.
We tried various subject lines across various audiences. Also tried to put the Test 1 subject line in Test 2 & Test 3. Still the same result.
My hunch is that Test 2 & Test 3 are directly going to spam/promotions. But don’t understand the reason for it.
Is anyone else facing the same issue?
