I want to email them all as quickly as possible (mainly on a one off or very occasional basis) Obviously quite a few of the old emails will no longer be valid.
I do not want to get my domain name somehow banned or blacklisted and I do not want to upset my ISP.
I guess sending 50 emails per day is safe but I would rather send 200 or so per day. I may even just write a macro and do it with Windows Live Mail??
What is the simplest way of me sending these emails as quickly as possible please? No sophistication required but I like read receipts as available in Live Mail and also the ability to include images.
Also should I set up my own mail server on my PC?
Thank you for your help.
