Acoustic Campaign Programs do not support direct selection of custom opt-out URLs within the Email step. In one-off mailings, custom opt-out URLs can be selected during mailing configuration under Delivery Options — but Programs do not provide an equivalent option. This article explains how to work around this limitation.

The limitation

Classic Programs have more limited delivery settings than standalone mailings. As a result, Program emails automatically use the default opt-out behavior and do not allow specifying different custom opt-out URLs per email step. This is particularly relevant for organizations that manage multiple brands or group companies, each requiring a unique unsubscribe URL.

Workaround: Use the URL link type in email templates

1. Create a separate email template for each company or brand that requires a unique opt-out URL.
2. In each template, insert the unsubscribe link using the URL link type instead of the Opt-out link type.
3. Manually enter the company-specific opt-out URL in the URL field — for example, https://company1.com/unsubscribe.
4. Use the appropriate template within the Program based on recipient segmentation or company affiliation.

This approach redirects recipients to the correct company-specific unsubscribe page.

Impact on click tracking

When using the URL link type for opt-out links, be aware that:

• Acoustic Campaign treats these links as tracked URLs
• Clicks on custom opt-out URLs are counted and logged in email reports
• There is no option to exclude specific URL link types from click tracking

As a result, opt-out clicks will inflate your overall click-through metrics. This differs from the native Opt-out link type, which handles unsubscribes separately and does not count them as standard link clicks.

Best practices

• Document which templates use custom opt-out URLs so your team can account for inflated click metrics
• Factor opt-out clicks into your analysis when reviewing Program performance reports
• Submit an enhancement request through the Acoustic Ideas Portal to request native support for custom opt-out URLs in Programs
