Quickstart
From a fresh account to your first unified thread — connect a channel, send a message, and watch SMS and email collapse into one conversation.
This walkthrough takes you to the moment it clicks: a single thread that holds both a text message and an email from the same person.
Connect a channel
New accounts land in the guided setup at /onboarding. It walks you through the steps to connect a first channel. It shows screenshots for Gmail and Outlook app passwords. It links directly to the Twilio, JustCall, and Skyetel credential pages. The inbox does not open until you finish this step.
You can add more lines later. Open Settings. Then go to Phone numbers or Email accounts to add one. If you get stuck, use Get free help setting this up. This link appears on the wizard and at the bottom of every setup guide. It sends your ask straight to our team, along with the step you are on. We will reply by email.
When setup finishes, the wizard offers a short feature tour at /onboarding/features — fourteen scenes covering the inbox, contacts and teams, the AI layer, and the developer platform. It stays one click away in the sidebar ("Explore features") for your first two days.
Send your first message
From the inbox, start a new conversation. Pick the channel to send from and a recipient. CommSync creates the contact and thread automatically.
SMS and Email messages both land in the same inbox.
Unify identities
When the same person reaches you on a second channel, open their contact panel. Attach or merge the new phone number or email address into their existing contact. Both channels then share one thread — see Merging identities for the full walkthrough.
Talk to CommSync through the API
Prefer to drive CommSync from code or an agent? Authenticate with an API key and call the MCP server.
curl -X POST "$COMMSYNC_API/api/mcp" \
-H "Authorization: Bearer csk_your_api_key" \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'Where to next
