Source, send, and enrich LinkedIn leads
The Chrome extension only reads pages you open. The Windows desktop app is the only component that sends invitations.
1. Connect the Chrome extension
- 1
Install Followthroo for LinkedIn
Get it from the Chrome Web Store . - 2
Pair it with your workspace
In Followthroo, open LinkedIn and copy the pairing token from Connect the Chrome extension. Click the extension icon, choose Settings, set App URL tohttps://app.followthroo.com, paste the token, then select Connect. - 3
Use it while signed in to LinkedIn
Keep LinkedIn signed in in that same Chrome or Edge profile. Open a people search, your connections, a company's people, or a profile, then tick the people you want. The extension adds people; it never sends an invitation or message.
For a long, existing list, use Import CSV or Excel in Leads with a LinkedIn URL column.
2. Review imports and errors
Open LinkedIn → Your LinkedIn → Logs. Each record shows the source URL, source type, result count, imported count, time, and any readable selector or page-reading error. A selector error means Followthroo could not safely read that page; it does not mean the people were rejected.
3. Send connection requests from the desktop app
- 1
Queue an invitation
Select leads in Leads and choose Connect on LinkedIn, or add a LinkedIn connection-request step to a campaign. Review the note choice before sending. - 2
Install the Windows app and sign in
Download the desktop app. It opens a dedicated Chrome window using a browser profile stored on your computer. - 3
Use the Send connections lane
The desktop shows the account's server-calculated sent count, remaining capacity, daily cap, and note allowance. The safe maximum is 20 invitations per account per day; you may set a lower account cap. Press Send connections only when you can leave that automation window alone.
The run stops on the daily cap, a LinkedIn limit wall, a sign-in prompt, or repeated technical failures. Sending automation can violate LinkedIn's terms and may restrict an account; use conservative limits and review your queue.
4. Look up profile contact information
LinkedIn profile enrichment is available on Grow ($20/month) and Scale ($50/month). Choose Find email and phone on a lead, select leads in bulk, or add the campaign step. The desktop's separate Profile enrichment lane performs the lookup; it never sends outreach.
Only confirmed 1st-degree connections are eligible. Followthroo checks the current profile badge, accessible label, and explicit Remove Connection action. It records a specific non-connection or unverified-degree reason instead of guessing. A lookup costs up to three credits: one is returned for each missing email or phone, and all are returned for a non-connection or technical failure.
Quick troubleshooting
- Extension is not connected: verify its App URL is
https://app.followthroo.com, paste a fresh token, and remain signed in to LinkedIn in the same browser. - No invitations send: check the desktop app's server usage/cap, LinkedIn sign-in, queue readiness, and the Activity log.
- Profile lookup is unavailable: Grow or Scale is required; then check the separate enrichment lane and its queue.
- A page could not be read: inspect LinkedIn → Your LinkedIn → Logs and share the page type and error with support.
