Infusionsoft is quite protective of their lists and how they send but it looks like you had 114,528 on your list and sent to 101,929 with 0 Skipped and 0 Errors. So the variance is due to several things such as the contacts didn’t have email addresses or there are some duplicates and/or 13,000 had opted out. You only had 12 Complaints, which is quite low, but maybe the bulk of them came during one segment that was sent, which created the warning.
