SendGrid Countdown Timer Generator for Email

A countdown image for SendGrid that takes its deadline from Handlebars template data in transactional sends or a custom field in Marketing Campaigns, and renders fresh on every open.
SendGrid Countdown Timer Generator for Email

Why Add a Countdown to Your SendGrid Sends

Transactional Emails Carry Real Deadlines

Order holds, invoice due dates, and verification windows already exist in your system. Pass them as template data and the timer counts down to them.

No Rendering Service to Build

One image URL with a Handlebars variable replaces a custom GIF generator in your stack.

Custom Design per Stage

Design the banner with your fonts and imagery, and add separate designs for the final hours and for after the deadline.

Correct on Every Open

The image is rendered when the email is opened, so a recipient who reads it hours later sees the true time left.

What a DynaPictures Timer Adds to SendGrid

Stages From One Template

Stages From One Template

Design the early banner, the urgent banner, and the after-deadline banner as stages of one timer. DynaPictures serves the stage that matches the offset to the deadline, so a single image URL in your dynamic template shows the right creative for every recipient.

Rendered at Open, Cached per Minute

Rendered at Open, Cached per Minute

Each open fetches a fresh image with the current time left and animates for 60 seconds. Transactional emails opened long after delivery still show an accurate countdown.

Handlebars in the Timer URL

Handlebars in the Timer URL

Append a Handlebars expression to the timer URL as the expire parameter, for example ?expire={{deadline}} with DD-MM-YYYY--HH-MM or an ISO 8601 value passed in dynamic_template_data, or use the formatDate helper on a timestamp. In Marketing Campaigns, use a custom field substitution the same way.

Everything in Every DynaPictures Timer

A Plain img Tag, Any Email Client

The timer is a GIF loaded through a standard img tag, so it shows wherever images do: Gmail, Apple Mail, Outlook, and SendGrid's own preview. Outlook for Windows displays the first frame as a still image.

Rendered When the Email Is Opened

Each open fetches a fresh image with the time left at that moment, then animates for 60 seconds. A subscriber who opens on day three sees day three, not the countdown from send time.

One Timer, a Deadline per Subscriber

Append a SendGrid date merge tag to the expire parameter and every recipient counts down to their own date. Format it as DD-MM-YYYY--HH-MM in the timer's timezone, or as an ISO 8601 timestamp with an offset.

Stages That Switch on Their Own

Design separate banners for the teaser, the final hours, and the time after the deadline. DynaPictures picks the right one from the offset to your target date, so the same URL keeps working across the whole campaign.

Opens by Campaign, Client, and Country

Every open is logged with the email client, country, and any custom query parameter you add. A SendGrid campaign name in the URL shows up as its own row in the analytics dashboard.

Gauges and Progress Bars

The remaining time can drive a radial gauge, a simple gauge, or a line progress bar in the same design. Digits are the default, not the only option.

Runtime up to 30 Days, Custom on Pro

Every plan runs a timer up to 30 days ahead of its deadline, which covers most promotions. The Pro plan lifts that limit for long-running campaigns.

No Hard View Caps on Paid Plans

The free plan serves 100 opens in total, enough to test a real send. Paid plans include a monthly view allowance sized to your list and are never throttled or watermarked.

Where DynaPictures Differs From Other Email Timer Tools

Live on Every Open

Many timer services pre-render one GIF at send time, so late openers see stale numbers. DynaPictures regenerates the image on each open and caches it for one minute.

Personalized Deadlines Through SendGrid Merge Tags

One published timer serves a different deadline per recipient through the expire parameter. Many tools support a single fixed date per timer.

Multi-Stage Designs

Separate designs for early, urgent, and after-deadline stages, switched automatically by offset. Many tools offer one design and a blank or zeroed timer after the deadline.

Gauges and Progress Bars Driven by the Countdown

Show the time left as a filling gauge or a shrinking bar as well as digits. Many email timer tools render digits only.

A Full Design Editor, Fonts Included

Any Google Font or an uploaded brand font, free layout, images, and an AI background generator in the same editor. Many timer tools offer a fixed layout with a color picker.

Analytics You Can Segment

Opens broken out by campaign parameter, email client, country, and time of day. Many tools report a single view count or nothing at all.

Frequently Asked Questions

Publish the timer in DynaPictures and copy its image URL. In the template editor add an Image module with that URL, or an img tag in the code editor, and append the expire parameter with a Handlebars variable.
