Outlook first frame
Why is my countdown timer not working in Outlook?
In short
Classic Outlook for Windows does not play animated GIFs — it shows the first frame and stops. That is only a problem when the first frame is wrong. A timer rendered at the moment of opening puts the correct remaining time in that first frame, so Outlook readers still see an accurate countdown; it just does not tick.
Classic Outlook shows the first frame of every GIF
The Windows desktop versions of Outlook that render email with the Word engine ignore GIF animation entirely. This is not specific to countdowns — every animated GIF in those clients is frozen on its first frame. Outlook on the web, Outlook for Mac and the mobile apps animate normally.
Why a correct first frame is the whole game
Some timer implementations put a logo, a loading state or a blank frame first and the digits after it. In classic Outlook that is all the reader ever sees. tikio renders the GIF when the email is opened and the first frame is always the current remaining time, so a reader who opens at 14:05 sees the time left at 14:05 — correct, just static. Reopening later shows a fresh render.
Other reasons a timer seems “broken” in Outlook
If Outlook shows nothing at all, images are probably blocked: Outlook often asks the reader to download pictures for senders it does not know yet, and until they do, the alt text is shown instead. Keep the alt text meaningful. If the timer shows at double size, the image tag has lost its width attribute — Outlook for Windows ignores CSS sizes and needs width on the tag. The code tikio gives you includes it.
<img src="https://t.tikio.io/e/a1b2.gif" alt="Offer ends Friday at midnight" width="480" style="border:0;max-width:100%;height:auto;" />What to test before a big send
Send a real test to a classic Outlook inbox and check three things: the digits appear (not a blank or a logo), they match the time left at the moment you opened, and they change when you reopen a minute later. If all three pass, Outlook readers get the same deadline as everyone else.

FAQ
Questions, answered
Can I force Outlook to animate the timer?
No. There is no code or setting a sender can use to make classic Outlook for Windows play a GIF. Design for a correct first frame instead — which tikio does by default.
Does the new Outlook for Windows behave the same way?
The first-frame limitation belongs to the older desktop versions built on the Word rendering engine. Test the clients your audience actually uses; whatever a client does with animation, a timer rendered at open shows a correct first frame.
Should I add a text fallback for Outlook?
Put the deadline in the copy as well — “Sale ends Friday at midnight” — for everyone, not just Outlook. It helps readers with images off and screen-reader users, and it keeps the email honest if the image is ever cached.
