Not tracked or wrong open data
- Emails not tracked by Mailtrack (grey checkmarks)
- Why is Mailtrack telling me that the recipient's mail service might not allow tracking?
- Mailtrack shows an email opened an unusual number of times
- Mailtrack isn't showing who's opened mails sent to more than one person
- Mailtrack is saying that an unopened email has been opened
- My email has been replied to but Mailtrack still says it hasn't been opened
