When to use <del> in email
- Showing the original price next to a sale price in promotional emails.
- Indicating outdated information in editorial corrections.
- Marking strike-through items in to-do or change-summary emails.
Rendering behaviour and edge cases
- Default <del> rendering is text-decoration: line-through, but some clients add light-red coloring as an editorial visual.
- Outlook on Windows respects <del> reliably; older Yahoo Mail occasionally strips the strikethrough.
- Pairing <del> with a <span> color override gives the most predictable visual across clients.
Recommended fallback strategy
Set text-decoration: line-through and a muted color explicitly on <del> elements. For maximum reliability, wrap the deleted content in <span style="text-decoration:line-through"> instead of relying on the default <del> rendering.
