I've enjoyed being a customer of TCH - support is great and the family atmosphere gives me the warm fuzzies. Nevertheless, I find myself moving yet another site to another host because of TCH's draconian limitations on e-mail.
First of all, let me be clear that there are few people more opposed to spam than I am. But I disagree with TCH's approach to it.
I run amysedaris.com, a semi-official fan site for actress/comedian Amy Sedaris. It's a completely non-commercial site except for the Amazon affiliate relationship we have that raises just enough commissions to pay for the site's hosting.
Fans ask to be notified by e-mail whenever the news portion of the site is updated. The mailing list currently has 245 addresses, and the blog software I use shoots a notification to all those people whenever there's a new blog entry. Let me repeat - the only people on the list are the people who asked to be, using a form on the site.
Yesterday TCH suspended my relaying privileges because it had determined I was sending commercial e-mail without complying with the Can Spam act. TCH never asked whether I was sending spam; it simply determined that I was doing so based on the volume.
I already moved another site I run because I was unable to use it for perfectly legitimate civil rights discussion mailing lists, and I found a host that takes a common-sense approach to bulk e-mailing, i.e. determining whether it's spam before limiting your ability to send e-mails.
So I'll take amysedaris.com to a new host as well. I still have some sites here, but they are low-traffic sites that use almost no e-mail. I will continue to recommend TCH to people for whom e-mail is not mission-critical, but I won't recommend it for sites that need to use bulk e-mail for legitimate purposes, as I do.
