Open Link
Configure clickable MP5 actions that open URLs, email links, phone links, or generated destinations
Use the Open Link connector when a viewer action should open a destination outside the current MP5 path. Typical uses include calls to action, product links, appointment links, email actions, phone actions, social sharing links, and destinations generated from viewer data.
Options
Option
What it controls
Notes
Trigger layer
The clickable layer that opens the link.
Confirm the layer is visible, reachable, and not covered by another element.
Link source
A direct URL, Dynamic Data field, Live Control value, or expression.
Use Dynamic Data for viewer-specific links and Live Control for shared campaign destinations.
Protocol
The link behavior, such as https://, mailto:, or tel:.
Confirm the protocol is supported by the target channel and device.
Fallback URL
The destination used when the source value is missing or invalid.
Use a safe default instead of leaving the action broken.
Generated link logic
Custom code that builds the destination from data.
Use only when a direct field or edit value cannot provide the link.
Tracking parameters
UTM or campaign parameters appended to the destination.
Confirm tracking values are encoded and do not break the URL.
Target behavior
How the link opens for the viewer.
Test in the intended delivery context, especially email and mobile.

Before publishing an Open Link connector, confirm:
The trigger layer is clickable and clearly communicates the action.

Dynamic link fields exist and use complete values.
Tracking parameters do not break the destination.
The fallback destination is safe and relevant.
The link behavior works in the target delivery channel.
