Include the option for html email
Robert Smith commented
Having HTML emails will improve usability (example following) and accessibility (WCAG 2.0).
Our IT recently added a link checker (urldefense.proofpoint.com) to our email that makes ILLiad links look like spam and/or a phishing email. Hiding the actual link behind a text would make it seem less "phishy" and conform with WCAG 2.0.
