LinkedIn Sync
Dex seamlessly syncs with LinkedIn. Once you've connected your LinkedIn account:
- LinkedIn Connections are added to Dex and kept up to date about once a day. We'll automatically update your contacts' titles, pictures, and more continually.
- You'll receive notifications when your LinkedIn Connections' titles change. When your connections start a new job, it's the perfect opportunity to reach out!
- Last Interaction is automatically updated with your latest LinkedIn conversation, allowing you to recall context, open relevant conversations with a click, and filter views based on the date of your last message for effective stay-in-touch reminders.
Setting up LinkedIn Sync
Install the Dex mobile app
Download Dex for iOS or Android and sign in to your Dex account.
Open Sync & Integrations in the app
Go to Settings → Sync and integrations, tap LinkedIn, then tap Connect LinkedIn Account.
Sign in to LinkedIn
A LinkedIn sign-in window opens inside the app. Enter your LinkedIn credentials and complete any two-factor prompt.
Wait for the initial sync
Your connections start importing right away. Depending on how many contacts you have, the first sync takes anywhere from an hour to 24 hours.

Setting up from the desktop app
The Dex desktop app connects LinkedIn the same way the mobile app does, if you'd rather not use your phone.
Open Sync & Integrations in the desktop app
Start the LinkedIn connection
A Sign in to LinkedIn window opens inside the app. Enter your LinkedIn credentials and complete any two-factor prompt.
Wait for the initial sync
Your connections start importing right away, the same as on mobile.
The desktop app also puts Sync LinkedIn Connections in its tray menu, which pulls immediately without waiting for the next cycle.
Do I need the Dex Extension?
Not for LinkedIn Sync. The Dex Extension is a separate browser tool for capturing and viewing contact information while you browse — it does not set up or maintain the LinkedIn sync, and installing it won't connect your LinkedIn account.
You can use both, or just the sync on its own.
LinkedIn Messaging Sync
With your LinkedIn account connected, you can see your last LinkedIn message for your contacts.
- ⏰ Last Interaction is automatically updated with your latest LinkedIn conversation, making keep-in-touch reminders even more accurate and powerful.
- 📝 See the last message sent in the conversation, so you can remember context on what you last talked about.
- 🔗 Open the relevant conversation with just one click, you can pick off where you left off.
- 🔎 Filter and create views with the date of your last LinkedIn message so you can make sure you're staying in touch.
Title Change Notification
After setting up LinkedIn, you'll be able to see title changes on the main Today page:

- By default, you'll receive emails about title changes, which you can turn off in the notification settings.
- Title changes are shown in the 'Today' feed from most recent to least recent.
- If contact is archived, you generally won't get title change notifications for them.
FAQ
Stop reconnecting at that point. Repeated reconnects are the one thing that won't help here: the sync picks up, runs for a few hours, and stops again, because the failure is on our side rather than in your LinkedIn login.
Email us at [email protected] and include:
- which app you connected from — mobile, desktop, or both
- which screen it stays on, and a screenshot if you can
- the Dex app version, so we can tell whether you already have the latest sync fixes
Those three things are what we need to check your account's sync state, and they save a round trip.
Premium syncs up to 2,500 LinkedIn connections and Professional syncs up to 9,000. Dex fills that allowance with your most recently added connections first.
Once you reach the limit, the sync keeps refreshing the connections already in Dex, so titles and pictures still update. It stops adding new ones. Nothing already in Dex is deleted, and the LinkedIn sync screen tells you when you have reached the limit.
Archived contacts don't count toward the limit, so archiving connections you don't need frees room for new ones.
No. The LinkedIn sync is all or nothing. It takes your first-degree connections up to your plan's limit, newest first, and there's no way to pick a subset, a category, or a group to bring in.
To control which contacts land in Dex and how they're grouped, import a CSV and assign groups as you import. See Importing from a CSV.
