This is a little bit brittle.  If I'm reading this correctly, you want to verify that email is visible on the page.  This particular assertion will break if, for instance, someone adds newlines around "Send to:" or changes to a `<span>` instead of a `<label>`.

A more flexible approach would be to apply an email-specific CSS ID to a `<div>` surrounding the email stuff.  Ideally, you would use an XML- or HTML-parser (lxml or beautifulsoup) to parse the contents, then use the CSS selector to check for the email div.  This allows for a lot of flexibility in whitespace, text, and UI elements.  If the HTML isn't well-formed, then you could fall back to using `assert_in` for the CSS ID.
