Introduction
When publishing a Broadcast campaign in Bookboost, there is a set of Advanced Settings available at the final Review and Publish stage that can significantly affect how — and to whom — your campaign is delivered. There are three toggles in this panel: Shorten Links, Prioritize Language, and Unique Strategy. Understanding each one helps you avoid duplicate sends, delivery issues, and ensure every guest receives the right message through the right channel.
Main Concept or Feature Explanation
The Advanced Settings panel is found in the last step of the Broadcast campaign builder: Review and Publish → Advanced (at the bottom of the page, next to the Publish buttons).
The panel contains three toggles or options, each controlling a distinct behaviour.
🔗 Shorten Links
When enabled, Bookboost automatically shortens any URLs included in your campaign messages. This is recommended for SMS and WhatsApp campaigns for two reasons: shortened links enable click tracking (you can see who clicked), and they prevent messages from being blocked. The platform warns that if links are sent via a public shortener in SMS, messages will most likely not be delivered to guests with phone numbers from the Nordics region due to carrier restrictions. Keeping Bookboost's own shortener enabled avoids this problem.
🌐 Prioritize Language
When enabled, the system determines which message template to send based on the guest's preferred language, even if that means choosing a different channel than the default. In other words, language takes priority over channel. When disabled, channel preference takes priority, and the system will send via the preferred channel using whichever language template is available for that channel.
🔁 Unique Strategy [DEPRECATED]
All broadcasts de-dupe by email AND phone at send time. Subsequent schedules to the same contact will fail with reason “already sent”.
Use Cases
📱 SMS to Nordic guests: Keep Shorten Links enabled to use Bookboost's own shortener and avoid carrier blocks for Nordic phone numbers.
📊 Tracking clicks: Enable Shorten Links to unlock click tracking for SMS and WhatsApp. If disabled, click data will not be available.
🌍 Multilingual properties: Enable Prioritize Language when you want guests to receive messages in their preferred language, even if it means using a secondary channel.
📣 Channel-first properties: Disable Prioritize Language if your priority is always delivering via a specific channel, and language flexibility is secondary.
Configuration and Setup
Navigate to Campaigns in the left-hand menu and open the relevant Broadcast campaign.
Click through to the Review and Publish step.
At the bottom of the page, click on ⚙️ Advanced to open the Advanced Settings panel.
Configure the options as you wish:
Shorten Links → Keep enabled unless you have a specific reason not to.
Prioritize Language → Enable if language matching is more important than channel preference. Disable to always send via the primary channel regardless of language.
Click Publish & Start Sending or Schedule the broadcast for a later time.
💡 Tip: As a best practice, if your audience may contain duplicate profiles and you are sending to email or SMS/WhatsApp, it is always worth enabling the relevant Unique Strategy to avoid sending the same guest duplicate messages.
Known Issues or Limitations
⚠️ Unique Strategy and audience size: Using By Email or By Phone deduplication on a Broadcast will reduce the number of messages sent compared to the total audience size shown. This is expected behaviour — the final send count reflects deduplicated profiles only.
⚠️ Shorten Links and tracking: Disabling Shorten Links means you will lose click-tracking data for SMS and WhatsApp campaigns. This setting does not affect email tracking.
Conclusion
The three Advanced Settings options — Shorten Links, Prioritize Language, and Unique Strategy — each control a distinct and important behaviour in how your Broadcast campaigns are delivered. Shorten Links ensures delivery and enables tracking. Prioritize Language ensures guests receive messages in their preferred language when it matters most. Unique Strategy protects your guests from receiving duplicate messages when your audience contains multiple profiles for the same person. Taking a moment to review these settings before every Broadcast helps you send smarter and avoid unnecessary guest frustration. ✅
