No they don't, to my surprise (I was just looking for this yesterday and was disappointed to have to try sendgrid since CF does not appear to offer any email sending API) That's not generic email sending to any address, that's just sending email ops notifications to your verified, fixed admin email address. Receiving emails is also well supported. But you won't be emailing your users this way Right now the functionality seems to try real hard to allow coming close to letting you send email to arbitrary addresses. I suspect actually dealing with spam management is a big enough hassle they don't want to get involved with it unless they're going to do it full heartedly.
