Add an open animation to your email

Last updated: November 11, 2026

An open animation is a single animation that plays once when your email is opened. You can choose confetti, fireworks, falling snow, falling leaves, flying reindeer, Christmas lights, or your own image. It applies to the whole email, not to one block.

Add an open animation

Open your email in the builder.
In the left panel, above the blocks, find Open animations and click Select email effect.
Switch on the effect you want: Confetti, Fireworks, Falling snow, Falling leaves, Flying reindeer, Christmas lights, or Custom.
If you chose Custom, pick the image you want to fall.

The canvas plays a preview of the animation when you switch an effect on or change one of its settings.

An email has one open animation at a time. Switching on a different effect replaces the current one. Once an effect is on, the dropdown shows its name instead of "Select email effect".

Adjust the animation

When an effect is on, sliders appear under it:

Size: Tiny, Small, Medium, Large or XL
Speed: from 0.1x to 3x
Quantity: Very few, Few, Some, Many or Most

Flying reindeer and Christmas lights have only the Size and Speed sliders. A new effect starts at Small, 1x and Some.

For Confetti, switch on All one color to make every piece the same color. It starts as your brand color. Click the color to pick a different one, or click Use brand color to go back.

For a Custom effect, your image shows under Selected image. Click Edit to choose a different one.

Remove the animation

Open Open animations and switch the effect off.

Ask Agent to do it

You can also describe what you want to Agent, for example "add falling snow" or "remove the confetti", and it sets up the animation for you. Clear requests work best. The assistant in the MCP connector can do the same on your templates.

Where it plays

Open animations play in email clients that show the interactive version of your email. Other recipients see the email without the animation.
