3. Campaigns

Campaigns are the engine of your LinkedIn automation in ReactIn. Once set up, they run your messaging flow on autopilot — across one or multiple LinkedIn accounts — based on a selected SmartList.

3.1 Create & Edit Campaigns

ReactIn lets you narrow down any SmartList using powerful filters to target your ideal customer profile (ICP) — without editing the list itself.

This means you can run ultra-targeted campaigns from a single, shared SmartList without duplicating data.

3.2 Smart Filters for ICP-Based Segmentation

Scaling your outreach? ReactIn allows you to connect multiple LinkedIn accounts to a single campaign. This means your leads are automatically distributed across those accounts — helping you stay efficient, compliant, and under the radar.

3.3 Rotation Logic Across Accounts

In ReactIn, every campaign starts by choosing its type — which defines how many steps will be sent and when.

3.4 Campaign Types: Invite Only or Invite + DM

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.

3.5 Message Variables & Fallbacks

ReactIn gives you control over how much time to wait between each message step in your campaigns — so your outreach feels natural, not robotic.

This helps you mimic human behavior and avoid triggering LinkedIn’s spam detection signals.

3.6 Configure Delay Rules Between Messages

ReactIn gives you full control over every campaign — so you can start, pause, resume, or duplicate flows at any time without losing progress.

This lets you stay agile and react fast to changes in your strategy, performance, or capacity.

3.7 Pause, Resume & Manage Campaigns

Connect external tools to automate lead capture and syncing.​

5. Manage Integrations

ReactIn makes it easy to connect your favorite tools — like forms, booking apps, or no-code platforms — so you can send leads directly into your SmartLists without writing code.

5.1 Connect External Tools to Push Leads into ReactIn

Once your tools are connected to ReactIn, you can easily monitor and manage them from a single place.

5.2 View and Manage Active Integrations

In ReactIn, integrations are not assigned to existing SmartLists.
Instead, you create a new SmartList that is directly connected to a specific integration.

This setup ensures leads are automatically collected in the right place — with zero extra config.

5.3 Link Integrations to SmartLists (the Right Way)

Monitor and analyze your campaign performance.​

ReactIn includes unlimited usage for most features, so you can scale your outreach freely — while keeping track of your enrichment credits.

7.2 Monitor Credit Usage

ReactIn is simple by design — there’s only one plan, and all billing operations (payment, receipts, upgrades) are handled securely via Stripe.

7.3 Manage Your Plan & Seats

ReactIn includes unlimited usage for the vast majority of features — but it's still important to understand how things work under the hood to use them responsibly.

7.4 Understand Unlimited Scraping & Usage

Ensure safe and effective LinkedIn automation practices.​

8. LinkedIn Account Limits

To keep your LinkedIn account safe, ReactIn sets default daily limits for each account — but you can customize them if needed.

8.1 LinkedIn Daily Action Limits

ReactIn doesn’t just queue messages and invitations — it uses a controlled execution system to spread actions out over time and reduce the risk of LinkedIn detection.a

8.2 Smart Throttling & Delay Logic

A shadowban happens when LinkedIn silently limits your account — your messages stop getting replies, your visibility drops, and things feel "off", but no warning is shown.

ReactIn is designed to minimize these risks, but it's essential that you follow best practices on your side too.

8.3 Shadowban Prevention

ReactIn uses the Chrome Extension to maintain a secure connection with your LinkedIn session — and it’s built to handle reconnections automatically, without any manual intervention.

8.4 Auto-Reconnect via Chrome Extension

Protect your data and manage account settings.​

9. Account & Security

ReactIn uses LinkedIn authentication only — no email/password login is required or supported.

9.1 Login & Authentication

To send LinkedIn messages via ReactIn, the Chrome extension is required. It ensures a stable and secure connection between your account and LinkedIn.
