(Tried a search, but no dice.)

I'm guessing when subscribing to e-mail newsletters via Snapper Mail, it is best to use the text option, as the HTML would be a memory hog, saving possible exceptions to news newsletters like the NY Times and its Circuits newsletter.

On the other hand, Services like PayPal payment account verification e-mails have a unique HTML format (unless they have a groovy text-based response form I don't yet know about.) which seems like a good thing to keep.

Question to the forum members: What have you used and what works best (practical vs. the essential)?
