Is there a reason the “sent” stats would be wrong on an email? This email was sent to around 14,000 people but it seems to only be counting some of them. The correct sent amount is shown on the graph when you click into the email. This just started happening on new emails I setup in the last week or so. Past emails have shown the correct stats.
I have now noticed that the sent bubble mismatch currently seems to only happen on this segment (segment filters shown in screenshot). I have even recreated this as a new segment with the same filters and sending to that new segment has the same results, sent bubble being under reported. This seems like a fairly basic set of filters. Is there maybe a bug with this filter setup? As far as I know I haven’t seen this with other segments I’ve created.
