email problem

[missesbell]

I am using orange for my emails (not sure if this is relevant!) and have just discovered that at least 2 of my contacts are not receiving my emails. Their addresses are correct and now I am concerned that I will have to revert to paper and pen. How do I find out who is getting my emails. There have been no bounce backs............HELP !!!

Double-check the address properties are absolutely identical to what they use (like a dot in name, etc)
Make sure you put something proper in Subject line .. Nothing is bad, as are "spammy words" Use a string of words that dont look like spam. These can be wiped from server.
Don't use web addresses in subject line ... Can get wiped at ISP.
Photos attached? If possible, zip them up and attach.
If you have a rude/odd/naughty email name .. make sure your friends add it to their server (ISP) webmail setup as an "ok to deliver/not spam" address.
