EmailTimer.App documentation
Technical reference documentation and guides for implementing countdown timers and personalized dynamic images in email campaigns.
Getting started
Start from a gallery design, set the deadline, publish, and paste the snippet into your email platform, with the labels the dashboard uses.
GuidesTimer types
Explore all six timer configurations supported by EmailTimer.App: fixed date, per-recipient, evergreen, count-up, and recurring.
GuidesMerge tags and personalization
Where a merge tag can go, where it cannot, and the two ways a subscriber's own name, code or deadline reaches an image.
GuidesPhotoshop timers
Design the whole thing in Photoshop, keep your own pixels, and let the numbers animate. The template, the rules and the refusals, stated plainly.
DevelopersREST API reference
Thirty two endpoints across templates, assets, signed image URLs, recipient sets and usage, on the Growth and Agency plans.
Tasks
-
Fonts in a timer, and where font upload stands
How fonts work in an EmailTimer.App template: the editor catalogue, what publishing refuses, Photoshop imports, and where font upload stands.
-
How opens are counted
One open is one image the image service renders and sends in full. What counts, what does not, the period it is counted over, and where to see the number.
-
Minting image URLs in bulk
Mint one signed timer image URL per recipient with the batch endpoint or a recipient list export, then import them into your email platform.
-
Move a free generator timer into your account
Move a free generator timer into your account with its claim code. The image you already sent goes from 500 opens to 1,000, and you get an editable copy.
-
Serve timer images from your client's own domain
Serve timer and personalized images from a client's own hostname on the Agency plan. The two DNS records, the certificate, and removing a domain safely.
-
What a timer shows when it is not counting down
The three pictures a timer image shows instead of a live countdown: the expired frame, the template fallback image and the service card.
-
What happens when a workspace goes over its plan
What happens when a workspace passes its monthly opens: the 80 and 100 percent emails, the corner watermark past 110 percent, and how it comes off.
Start here if you send to Apple Mail or Gmail
Apple Mail pre-fetches and caches images at message delivery time, while Gmail proxies and caches per recipient upon first open. The Apple Mail page says what that does to a timer and which deadline model survives it.
