Plaintext "Verify Email address" email has a copy of the CSS and doesn't include the verification URL

[nomis]

Content-Type: multipart/alternative requires that the content be the same in both text/plain and text/html but the plaintext part is unusable. It would be acceptable to fix this by omitting text/plain and only using text/html content.

Example:

--mk3-ab99c453d534443aacf82ed276fb1e48
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
