So...I bought Arelis, and then sought some link partners for my comparative religions site. I want to increase my visibility you see.
So I set up a search and got just under 1000 search partners listed. I skimmed through the list and removed a couple of major religion sites I didn;t expect at all to reciprocal link.
Then sent them all (one by one!

).
Thing is, I discovered from the replies that I should have checked the list much more closely!
Somehow, for a link partner search - via Google - for the search terms "religions of the world" and "christianity", I ended up e-mailing 123-reg and the Whitehouse, amongst others.
I was pretty horrified, actually, to read the auto-reply from whitehouse.gov, about how George W Bush takes the concerns of his citizens seriously. I guess a reciprocated link to a UK religions resource site is out of the question?
Anyway, I think my first foray into e-mail marketing - limited though it was - is very clear: be very careful who you are sending to!
Obviously, if you don't target your e-mails properly, it's your own time you're wasting as well.
