If you read your email in Outlook on Windows, the button in a SIMCOAI email was white text on nothing. That included the “Set a new password” button in a password reset, so anybody resetting a password from Outlook had to find the web address printed underneath it instead — or gave up. We had coloured the button with a gradient and given it no plain colour underneath, and Outlook draws no gradients, so it fell back to no background at all. Every button in every email we send now has a solid colour behind it and stays readable wherever it is opened.
Our emails also now match the rest of SIMCOAI. The colours, the heading sizes and the logo had drifted away from the website over time — including a pink that appears nowhere else in SIMCOAI — so an email from us looked like it came from somewhere adjacent to us. That matters most on a password reset, which is the one message where looking unfamiliar reads as a scam. The emails the sign-in service sends on our behalf and the emails we send ourselves are now built from one shared design rather than two copies of it, and a check measures them against the live website so they cannot drift apart again.
We have also stopped putting a screenshot of the dashboard at the top of these emails. It was cropped by a rule that no email app supports, so instead of a neat banner most people were sent the full-size picture — and it showed a menu we replaced on 17 August.
