Make all email template text left-aligned, excluding call-to-actions buttons which should remain centered
In the emails needing updates, remove font styling from HTML tags other than <td> and <p>
Add an additional margin above and below each call-to-action button
For emails that include only the “ignore” warning below the call-to-action button move the warning up, so the button is the last item displayed
