Why a Dynamic Countdown Beats a Static GIF
Generated, Not Drawn in Advance
A static GIF is rendered once. A dynamic timer is generated from the current time and the recipient's deadline at each open.
Dynamic Beyond the Digits
Stage designs switch by offset, and gauges or progress bars fill from the same countdown value.
Consistent Across Clients
Because it is an image, the result looks the same in every client that shows images; only animation support differs.
One Template, Many Variations
One design serves every recipient and every stage with no extra assets.
What Makes a DynaPictures Timer Dynamic
A Design as Dynamic as Its Data
Build stages in the countdown timer generator and add a radial gauge, a simple gauge, or a line progress bar driven by the remaining time. The rendered image reflects both the deadline and the stage at the moment of open.
No Pre-Made Frames to Go Stale
Each open produces a fresh 60-frame GIF from the current time left, cached for one minute per deadline. Nothing is stored ahead of the send.
Generated on Demand
The image URL carries the expire parameter and any custom parameters; the server renders the design with those values and returns the GIF in the same request.
Everything in Every DynaPictures Timer
A GIF in a Standard img Tag
No JavaScript, no HTML5 animation, no client-side script. The image loads in Gmail, Apple Mail, Outlook, and mobile clients; Outlook for Windows shows the first frame.
Rendered per Open, Cached per Minute
Each open fetches an image with the exact time left at that moment. Images are cached for one minute per deadline and then regenerated, and each one animates for 60 seconds.
The expire Parameter
Append ?expire=DD-MM-YYYY--HH-MM (interpreted in the timer's timezone) or an ISO 8601 timestamp with an offset to the URL. Merge tags from your email service provider (ESP) fill it per recipient.
Stages by Offset
Each timer holds several designs, each with an offset from the target. Before, at, and after stages are selected on every render.
Every Open Logged
Email client, country, locale, and any custom query parameter are stored per open. Raw IP addresses are never kept, only a hash and the derived location.
Countdown-Driven Gauges
Radial tick gauges, simple gauges, and line progress bars take their value from the remaining time, next to or instead of digits.
REST API
Create, update, publish, preview, and read analytics for timers programmatically with an API key.
Plan Limits, Stated Plainly
Timers run up to 30 days ahead on Free, Lite, and Standard and without limit on Pro. Free serves 100 opens in total; paid plans have a monthly view allowance and no hard cap.
How to Set Up a DynaPictures Countdown Timer
Design It in the Generator
Open the DynaPictures countdown timer generator, set the target date and timezone, design one or more stages, and publish. You get a URL ending in .gif.
Embed the URL
Place the URL in an img tag or an image block in your email service provider (ESP). Append ?expire= with a merge tag for per-recipient deadlines.
Read the Analytics
Add any custom query parameter to segment opens, then watch them arrive in the analytics dashboard or pull them through the API.

Where DynaPictures Differs From Other Timer Tools
Rendered at Open
Many timer services generate one GIF at send time. DynaPictures generates per open, so the number on screen matches the clock.
Per-Recipient Deadlines
One URL, a different deadline per recipient through the expire parameter. Many tools support one date per timer.
Multi-Stage Designs
Before, at, and after designs switched automatically. Many tools show one design and a zeroed clock.
Gauges and Progress Bars
Remaining time as a gauge or bar, not only digits. Elsewhere, digits are usually the only option.
A Real Design Editor
Google Fonts, uploaded fonts, images, and an AI background generator. A fixed layout with a color picker is the common alternative.
Segmentable Analytics
Opens by custom parameter, client, country, and hour. A single total is what many tools offer.

Frequently Asked Questions
The image is generated when the email is opened, from the current time and the recipient's deadline, rather than rendered once at send. Stages and gauges are part of that generation.
