emails not delievered

16. October 2013 · Write a comment · Categories: Hotmail, Outlook.com · Tags: ,
Increasingly over the years, with hotmail and now outlook, my group emails are not being received.
I send about 500 at a time every 2 months.  People have been on that list for nearly 14 yrs no longer receive them.
It's so bad that it has severely affected my part time business.  I do yoga retreats.
Can someone tell me how to fix this or how to export all my contacts to a reliable email service.
Thanks
