Mass emails for events occurring during a holiday period are generally bad.
Chances are that the person you’re emailing is out of the office, so will not read the email till they are back in.
Secondly, and more importantly, chances are that they will have an out of office auto-responder that Microsoft so kindly added as a feature in Outlook/Exchange.
For all of you that have sent out Seasons Greetings via email, I hope you enjoyed the torrent of “I’m sorry but I am out of the office” emails.
May this be a lesson to you all that sending mass emails is bad!
