Quick answer: Add one short seasonal greeting (for example “Wishing you a happy holiday season”) and, if needed, your office closure dates under your normal signature. Use an inclusive greeting for clients, keep any banner under 600×150px, and switch back to your usual signature in early January.

How to announce office closures in your signature
Your signature is seen on every email, so it is the perfect place for holiday hours. Keep it to one line with exact dates, and point to a backup contact for urgent requests:
Pair it with an out-of-office auto-reply for the days you are actually away.
Holiday banners and images for email signatures
- Size: up to 600×150px displayed, uploaded at 2× for sharp screens. See our size guide.
- Animated GIFs are fun, but classic Outlook for Windows shows only the first frame, so make sure that frame works on its own.
- Host the image instead of attaching it, or it may show as an attachment.
- Emoji such as 🎄 ❄️ 🎁 are the lightest way to add color, and they work in every modern email app.
When to add and remove your holiday signature
Switch to your holiday signature in early December (or the week before Thanksgiving) and back to your normal one in the first week of January. In SignTry, keep your holiday version as a second signature and copy whichever one fits the season; for teams, update everyone at once by generating from a CSV.
