Countdown timers and personalized images for Adobe Campaign
Your subscribers see how long is left on the offer, counted from the moment they open the message, and it goes into the Adobe Campaign campaign you have already built. One snippet, in the merge syntax Adobe Campaign already uses.
Adobe Campaign merge syntax
The tags you already use, around the image
The same merge fields that put a subscriber's name in your subject line go in the link and the alt text around the image, where Adobe Campaign fills them in as it sends. They never go inside the image address, for the reason in the warning further down. A name or a deadline drawn inside the image itself comes from an address signed for each subscriber, held in a contact field.
- First name
- <%= recipient.firstName %>
- Coupon code
- <%= recipient.couponCode %>
- Deadline
- <%= recipient.offerDeadline %>
- Email address
- <%= recipient.email %>

The snippet to paste into Adobe Campaign
Put it in email designer html source, or a content fragment. There are two shapes, and which one you want depends on whether every subscriber gets the same deadline or their own. The editor generates whichever you pick, already filled in with your ids.
One image for the whole send
On every plan, including the free one. Everybody requests the same address, and the clock is worked out at the moment each person opens, which is what lets one address show a different time to every reader. The name and the code go in the link and the alt text.
<a href="https://yourstore.com/sale?code=<%= recipient.couponCode %>" target="_blank" rel="noopener">
<img src="https://img.emailtimer.app/i/k7mQ2pXd.gif?w=w_8ha3fq&v=3&sig=YOUR_SIGNATURE" alt="<%= recipient.firstName %>, your 25% off ends at midnight tonight" width="600" height="200" border="0" style="display:block; width:100%; max-width:600px; height:auto; border:0;" />
</a>A different image for each subscriber
On Growth and Agency. Generate one signed address per subscriber, import the column into
Adobe Campaign as a contact field called
etImageUrl,
and point the snippet at that field. This is the only way a deadline that differs per subscriber can
work, because the deadline is inside the signature too. A contact whose field is empty gets no
image, so check the field is filled across the whole segment before you send.
<a href="https://yourstore.com/sale?code=<%= recipient.couponCode %>" target="_blank" rel="noopener">
<img src="<%= recipient.etImageUrl %>" alt="<%= recipient.firstName %>, your 25% off ends at midnight tonight" width="600" height="200" border="0" style="display:block; width:100%; max-width:600px; height:auto; border:0;" />
</a>The addresses come from the batch endpoint in the REST API, or from a CSV export if you would rather not write code.
Setting it up in Adobe Campaign
Four steps, and the longest one is deciding what the timer should look like.
-
1
Build the image in EmailTimer.App
Choose the timer style, set the deadline, and name the fields you want to personalize. Pick Adobe Campaign as your platform so the snippet comes out with the right personalization syntax already in it.
-
2
Copy the Adobe Campaign snippet
EmailTimer.App writes the image tag using Adobe Campaign personalization fields in the form <%= table.field %>, which is the same syntax your team already uses in subject lines and body copy.
-
3
Paste it into the delivery content
Open the HTML source of the email designer, or the content fragment you reuse across deliveries, and paste the tag where the banner would normally sit.
-
4
Check it in delivery preview
Run the delivery preview against a real profile. During delivery analysis Adobe Campaign replaces each field with that recipient’s value, so preview is where you confirm the name and the deadline are landing.
Things that only matter in Adobe Campaign
Adobe Campaign personalization fields take the form <%= table.field %>, so a recipient first name is <%= recipient.firstName %>. Adobe Journey Optimizer, the newer product in the same family, uses a different syntax based on double braces; if your team is running both, use the Journey Optimizer page for those deliveries.
Before procurement asks
You will have to explain this to someone in security
Running Adobe Campaign usually means a review before anything new goes near a send. The short version you can forward: an image URL goes in the template, the values it carries are the merge fields you choose, and no script runs anywhere. Nothing is installed inside Adobe Campaign and no data leaves your platform except what you put in that URL.
The Agency plan adds white-label image domains, so the URL your subscribers see reads as your own brand rather than ours, along with a separate workspace per brand or region and control over what each person on the team can touch. There is no dedicated IP option and no written uptime commitment; what the service does when something fails is on the status page.
What your Adobe Campaign subscribers will actually see
Enterprise sends often go out across several waves. Fixed deadlines stay correct in every wave and in every email client, because the countdown is calculated against the deadline rather than against send time.
What each client is documented to do
The Apple and Gmail rows rest on Apple's and Google's published documentation and on third-party testing. Neither company publishes a cache lifetime: Apple documents the prefetch, Google documents the proxy, and the two to three days is FreshInbox's 2021 testing. The Outlook and Yahoo rows are what we expect those clients to do, with no vendor document behind them. No row comes from a test by us yet, and we will publish dated screenshots when we have them.

Adobe Campaign questions
Before you put a timer in Adobe Campaign
Where do Adobe Campaign merge tags go in the snippet?
In the link and the alt text, where Adobe Campaign fills them in as it sends. Never inside the image address, which is signed, so a value filled in after signing breaks the image for the whole send. On this page the four common ones are <%= recipient.firstName %> for a first name, <%= recipient.couponCode %> for a code, <%= recipient.offerDeadline %> for a deadline and <%= recipient.email %> for the address. A name, a code or a deadline drawn inside the image itself comes from an address signed for each subscriber and held in a contact field, <%= recipient.etImageUrl %>. Adobe Campaign personalization fields take the form <%= table.field %>, so a recipient first name is <%= recipient.firstName %>. Adobe Journey Optimizer, the newer product in the same family, uses a different syntax based on double braces; if your team is running both, use the Journey Optimizer page for those deliveries.
Where does the snippet go in Adobe Campaign?
Into a email designer html source, or a content fragment. Open the HTML source of the email designer, or the content fragment you reuse across deliveries, and paste the tag where the banner would normally sit. Nothing is installed in your Adobe Campaign account and no permissions are granted to us, because the timer is an ordinary image tag pointing at a URL.
Will the countdown be accurate for my Adobe Campaign subscribers?
Enterprise sends often go out across several waves. Fixed deadlines stay correct in every wave and in every email client, because the countdown is calculated against the deadline rather than against send time. The general rule holds whichever platform you send from: a fixed deadline survives image caching intact, because the image counts toward a real timestamp, while an evergreen timer that starts at open time degrades when a client pre-fetches or caches. Apple Mail Privacy Protection fetches at delivery and testing reports it holds the image for two to three days, Gmail caches per recipient for a lifetime Google does not publish, and Outlook on Windows shows the first frame only.
Campaigns to build in Adobe Campaign
Each playbook says which timing model the campaign needs, which snippet it takes, and what to get right before you send it.
Setting this up on another platform
The snippet is the same everywhere. Only the merge syntax changes, and each page below carries the exact syntax that platform expects.
