# Postscript

> Use affiliate events to trigger SMS campaigns.

Postscript is an SMS platform for ecommerce. Connecting it to Afflo lets you send text messages that respond to partner activity — a gentle way to reach creators who already share their number.

## What it does

* Sends affiliate events to Postscript (joined, first sale, payout sent)
* Syncs partner properties so you can segment SMS lists
* Lets Postscript automations trigger from Afflo events

## Before you start

* A Postscript account
* API key from **Postscript → Settings → API**

## Connect

1. Create an API key in Postscript.
2. In Afflo, open **Integrations → Marketing → Postscript** and click **Connect**.
3. Paste the key and save.

## Typical use cases

* Welcome SMS to affiliates who opt in to texting
* "Your payout is on the way" confirmations
* Urgent campaign pushes ("Launch today — grab your code now")

## Tips

* SMS has a much lower tolerance for volume than email. Reserve it for messages with clear, timely value.
* Always honor opt-outs; Postscript manages this, but double-check your affiliate SMS list is opted in.

## Troubleshooting

**Events missing in Postscript.** Confirm the API key has write access. Try a manual test from Postscript's event log to rule out connectivity issues.
