6 Tips for Email CSS Render Testing
Last but not least, you must create free accounts with all the major ISPs or at least the mailboxes that are contained in your target list. This approach lets you see firsthand how the email renders in each platform and lets you make any changes you need. However, if you choose this path, make sure to check your inboxes over a wide variety of Internet browsers. Remember: Browsers also have their own standards of reading HTML code.
To satisfy the unique requirements of the major mailbox providers, here are the six major dos and don'ts of using CSS in your emails:
- Do not try adding style tags to your head tags
- Do not use external style sheets
- Do test background images across all email clients
- Do use a font tag on anything that involves content
- Do steer clear of using CSS positioning
- Do not use div tags unless absolutely necessary
Emails that render properly ensure your messages are delivered. If your email does not render as you intend it to then you will lose subscribers and diminish your deliverability reputation.
