Start setup
  1. Step 01

    Create your DeskFerry account

    Sign up at deskferry.app — it takes 30 seconds and starts a 7-day free trial. You'll land on the dashboard where you can create your first workflow.

  2. Step 02

    Authenticate Customer.io

    Click "Add Connection" and select Customer.io from the app directory. You'll be redirected to Customer.io's authorization page. Grant DeskFerry access to your campaigns, audiences, and analytics data. You control which lists and campaigns the integration can modify.

  3. Step 03

    Authenticate Segment

    Same process for Segment. Click "Add Connection," select Segment, and authorize access. Grant DeskFerry access to your dashboards, reports, and datasets. You select which data sources the integration can read.

  4. Step 04

    Choose your trigger

    Select what event starts the workflow. For this integration, popular triggers include: new subscriber in customer.io or report generated in segment. The trigger fires automatically whenever that event happens — no manual intervention.

  5. Step 05

    Configure the action

    Define what happens when the trigger fires. For example: log event in segment. Map the data fields between Customer.io and Segment so the right information lands in the right place.

  6. Step 06

    Test and activate

    Run a test to confirm data flows correctly between Customer.io and Segment. Check that the fields map as expected, then toggle the workflow on. It runs 24/7 from here — DeskFerry handles retries, error logging, and monitoring automatically.

FAQ

Frequently asked questions

How do I connect Customer.io to Segment?

Sign up for a free DeskFerry account, then click "Add Connection" to authenticate both Customer.io and Segment via OAuth. Choose a workflow template — like syncing marketing events to data analytics actions — customize the field mapping, and activate. The entire setup takes under 5 minutes.

What can I automate between Customer.io and Segment?

You can automate a wide range of workflows: sync new Customer.io events to Segment actions, trigger Segment updates when Customer.io data changes, create Segment records from Customer.io events, and build conditional workflows with filters and field mapping. Each workflow runs 24/7 with automatic retries.

Is the Customer.io and Segment integration free?

DeskFerry's 7-day free trial is enough to prove the workflow out. If your Customer.io-to-Segment workflows need more volume, paid plans start at $49/month with unlimited workflows and priority execution.

Is my Customer.io data secure when connected to Segment?

Yes. DeskFerry uses OAuth 2.0 for authentication — we never store your Customer.io or Segment passwords. All data is encrypted in transit (TLS 1.3) and at rest (AES-256). Your marketing data is only accessed when a workflow runs, and you can revoke access at any time from your DeskFerry dashboard.

Can I sync data both ways between Customer.io and Segment?

Yes. You can set up workflows that trigger from either Customer.io or Segment. For example, create a workflow where Customer.io events update Segment, and a separate one where Segment changes sync back to Customer.io. Each direction is configured independently so you have full control.

Do I need technical skills to connect Customer.io and Segment?

No coding is required. DeskFerry's builder is prompt-based: you describe the trigger and what should happen in plain English, and the agent handles the field mapping. If you can use Customer.io and Segment, you can set up the integration. Most users are running their first workflow within 10 minutes.
