3.5 Message Variables & Fallbacks

ReactIn makes it easy to write personalized LinkedIn messages at scale — using dynamic variables and fallbacks that adapt to each lead's data. This ensures your campaigns stay relevant and human — without needing to rewrite messages one by one.

📦 Use dynamic variables

When writing a message, you can insert variables like:

  • First name

  • Last name

  • Company name

  • Job title

  • Any custom field from your SmartList

ReactIn will automatically replace these with the correct data for each lead when sending.

🧠 All imported or enriched fields from your SmartList can be used dynamically in messages.


🧱 Add fallbacks to avoid blanks

If a variable is missing (for example, a company name), you can define a fallback — a default phrase that will appear instead.

This ensures your message always flows naturally, even when some data is incomplete.

📌 Fallbacks help you avoid awkward gaps like "How’s everything at ?" and keep things smooth.


🔍 Preview messages before launching

Before activating your campaign, you can preview how your message will look for each lead:

  • Go to the campaign step

  • Click Preview

  • Scroll through different leads to see how variables render in context

✅ This lets you catch missing values or formatting issues early — before anything is sent.


💡 Pro tip: Use short variables early in the sentence and keep your message readable even if a fallback is applied.
