Poor Timing: Sending emails at the wrong time can reduce the chances of them being opened and read. Frequency: Sending too many or too few emails can lead to disengagement. Finding a balance is crucial. Bad Subject Lines: Subject lines that are not compelling or are misleading can result in low open rates.
