You probably won't be broadcasting your email address on a dating profile anyway, but don't even give one out that includes any personal information to people you've been chatting with, but haven't yet met. (dating.lovetoknow.com)
In addition to these autoresponders, I also send a weekly broadcast email. (stevescottsite.com)
IMPORTANT NOTE: The Savvy Inspector's Partner Vendor for broadcast email is Get Response. (thesavvyinspector.com)
