How to put one widget inside another

Last updated October 31, 2026

Some widgets can contain other widgets. That lets you build things a single widget can't do alone, like a countdown timer whose design changes by segment, or a personalized image with a live forecast in it.

What can go inside what

Container widget	What you can put inside it	How
Rule-based Images	Countdown timers, personalized images, weather widgets (as the image a rule shows)	Add Image, then choose the Timers, Image Personalization Widgets or Weather tab
Image Personalization	A rule-based image, and one weather widget (as layers)	Dynamic Image and Dynamic Weather in the left sidebar
Critical alerts	A rule-based image and a weather widget (as layers)	Dynamic Image and Dynamic Weather
Social proof counters	A rule-based image and a weather widget (as layers)	Dynamic Image and Dynamic Weather

Examples

A different timer per segment. Create two countdown timers with different designs, then a rule-based image that shows the first to VIP subscribers and the second to everyone else.
A forecast in a travel email. Create a personalized image with the subscriber's name and destination, and add a Dynamic Weather layer showing that destination's forecast.
A weather warning banner. Add a weather layer to a critical alert and switch the alert on when a storm is coming.

Things to know

Create the inner widget first, then add it to the container.
Rule-based images used inside another widget can only show uploaded images, not other widgets. If yours is missing from the list, check that every image in it is an uploaded image.
One weather widget per personalized image.
Merge tags from inner widgets are added to the container's code, so you only paste one piece of code into your email. Replace any placeholders as usual.
Changes flow through. Edit the inner widget and the container picks up the change.
