Installation, Activation, and Onboarding

Install RSender, activate the device, and complete the first-run checklist safely.

Install

  1. Download the RSender installer supplied for Windows or macOS.
  2. Complete the operating system’s installation steps.
  3. Launch RSender and choose Chinese or English.
  4. Review the local data location before importing production data.

Only install updates from a RocketsSend-provided source.

Activate this device

RSender uses an activation code tied to one device. Open Settings → Activation & Device, enter the code, and complete online verification. The license panel shows status and remaining time.

License states include active, expiring, critical, expired, and unactivated. When activation is absent or expired, sending is locked while available data remains viewable for recovery and renewal.

Before moving to another computer, deactivate the old device through the supported workflow. Hosted add-on entitlements are associated with the activation and follow it after a valid device move.

Complete onboarding

Use the first-run checklist in this order:

  1. Confirm language, theme, and storage.
  2. Add and authenticate a domain.
  3. Add a sending account and test it.
  4. Set a conservative global send strategy.
  5. Import a small permissioned contact sample.
  6. Create and enable a template with unsubscribe access.
  7. Send a test to an inbox you control.
  8. Create a small campaign and review preflight.

Do not begin with the full audience. A small controlled run verifies credentials, DNS, rendering, unsubscribe behavior, and queue policy.

Activation troubleshooting

  • Check the device clock and internet access.
  • Copy the complete code without leading or trailing spaces.
  • Confirm that the code is for RSender, not an add-on.
  • If the device limit is reached, complete deactivation on the previous device.
  • Preserve the exact error and export safe diagnostics.

Never share complete activation or add-on codes in screenshots or public support channels.
