Do timers work in all email clients?

As an e-commerce marketer, I'm exploring countdown timers for my email marketing campaigns, but I'm concerned about cross-client compatibility. I need to understand which email clients support live timers, how they render across different platforms, and what alternative strategies I can use to create a sense of urgency if timers aren't universally supported. What are the technical limitations and best practices for implementing email countdown timers?

TL;DR - Quick Answer

Email countdown timers work partially across clients. Static GIF timers have broadest compatibility, while live HTML/CSS timers function best in modern email clients like Gmail, Apple Mail, and Outlook web versions. Fallback strategies are crucial for comprehensive coverage.
