Dex's updated integration with Google Calendar and Gmail gives you a more powerful way to stay on top of your relationships—faster syncs, smarter updates, and new workflows to save time.

By connecting your Google account, you can:

  • Automatically update the last interaction based on emails and calendar events
  • View relevant calendar events and email threads for each contact
  • Search across multiple calendars and email subjects
  • Add notes to calendar events with ease
  • Start an email from a contact: open a Contact, click ActionsSend email, and Dex opens a new message in your computer's default mail app
  • Enable auto-add: automatically add people you email or meet moving forward

💡 For existing users: this upgrade requires reconnecting your Google account in Dex.


What's New?

  • Real-time sync: Emails and calendar events are reflected on Dex almost instantly
  • Auto-add workflow: Automatically create Dex contacts for people you email or meet (forward-looking only)
  • Send email from a contact: Open a contact → click Actions › Send email to hand the address to your default mail app
  • Smarter contact linking: Dex matches contacts based on email address or calendar attendee name

Getting Started

Go to your Sync & Integrations page

From the home page, click the dropdown icon at the top-right corner and choose Sync & Integrations.

Connect your Google Account (Gmail + Calendar)

Under Gmail or Google Calendar, click Connect Account and follow the login prompts.


Email Sync Details

  • Clicking on an email in Dex will open the full thread in Gmail
If you don't see any emails, confirm that the contact's email address is saved in their card and reconnect the sync if needed.

What Send email does

Actions › Send email on a contact hands the address to your computer's default mail app and opens a new message there. Dex does not send the message itself.

  • If your computer has no default mail app set, clicking the button appears to do nothing. Set a default mail app in your operating system settings and it will work.
  • You cannot pick which connected account the message comes from. It goes out from whatever account your mail app sends from, which may not be the account you connected to Dex. To choose a sending account inside Dex, use Mail Merge.

The button behaves the same whether your email sync has finished or not. A message that opens in the wrong app is not a sign that sync is still running.


Calendar Sync Details

  • Dex shows relevant events where the contact's email is listed as an attendee, or where their name matches the calendar invite
  • Dex syncs only the primary calendar for each connected Google account


Things to Know

  • Initial sync may take a few hours; after that, changes sync within 2 minutes
  • Works only with Gmail and G Suite accounts for email sync
  • You can manage both Gmail and Calendar sync from the same Google account connection—no need to connect separately anymore
  • Read-only. Dex asks Google for read-only access and never sends anything back, so contacts, edits, and notes you create in Dex do not reach Google Contacts, Gmail, or your calendar. To put your Dex contacts on a phone or a Mac, use Two-Way Contact Sync, which writes to the device's own address book rather than to Google
