One of the PR folks I communicate with regularly asks, in response to this post, how those who send releases via e-mail will know that anti-spam filters haven't killed their release? Many publicists, for example, send blind carbon copies to dozens of journalists and the receipt of a message with an address in the BCC field might trigger a filter. It's a good question and here's a modified version of my reply to that individual:
I know I've fought with varying degrees of success to have all filters taken off my corporate addresses. There are no filters on dakin@[nospam]globeandmail.ca but there are filters normally on any globeandmail.ca address. There are also filters on all ctv.ca addresses, including mine. I believe there are no filters on david@davidakin.com as well, although my hosting provider claims to have some anti-spam filter.
But I would never know, of course, if some legit mail didn't make it through. That's one of the biggest problems with server-based mail filters. The intended recipient not only has no idea what mail s/he missed but can't tell his or her correspondents what rules trigger the filter. I hope most spam filters are most sophisticated than filtering out anything with an address in the BCC field.
One more reason, though, to make press releases available via an RSS feed!
