<link> in email clients

Works in 3 of 21. Not supported in Gmail, Gmail Android, Gmail iOS and 15 more.

Your reader in Gmail sees the email without <link>, even if it looks right where you tested it.

The fix for Gmail

Inline all CSS instead of using external stylesheets

after
<div style="max-width: 600px; margin: 0 auto;">
  <div style="background-color: #6d28d9; padding: 32px;"></div>
</div>
Show the original
before
<head>
  <link rel="stylesheet" href="styles.css" />
</head>
