I have posted want ads and have responded to all inquiries (except obvious scams). I think it would be nice to get a thank you from people when I send pictures, pedigree and other information. How am I to even know that they received the information if I don't even get an acknowledgement?
Don't foget that even in this age of technology, some e-mails just don't go through (ISPs sometimes don't "get along", e-mail addresses missed typed and such). I had that problem when I was looking to buy my yearling. I sent an e-mail to the seller (direct link from their site and copy and paste to my e-mail account), got no response... I happened to mention this to a friend that knows the seller, she told me that the seller always responds to inquiries, so I called the seller on the phone (long distance), she had not received my e-mails. I had to give her my e-mail address over the phone, and it still took a couple of tries for e-mails to get through. But, it obviously worked out, since I have my yearling. We spoke a couple times on the phone, but most of the questions and such were dealt with through e-mail. I like to see things in writing, as it helps to clarify information for me.
If you are really interested in the horses you inquired about, you may want to go ahead and use the phone.
I have a hotmail account and the account that came with my ISP. The instance with my mini is the only time that I know of that that account (the ISP account) hasn't worked properly. I know there are problems with Hotmail, it's a free account, so they are used extensively by scammers and such. Just about every hotmail e-mail I receive into my hotmail account goes straight to the junk folder. I have to accept them as "good" e-mail or they just don't go to my in-box.
Didn't mean to ramble quite so long.
