Connect Customer Outbound Campaigns adds dynamic source addresses

Posted on: Jul 29, 2026

Amazon Connect Customer journey flows can now set the source address dynamically in the Send Communication block, so each contact is reached from a sending number or email address that matches their region or brand. The source value comes from a flow attribute or from the output of an AWS Lambda function. Dynamic source addresses work across voice, email, SMS, and WhatsApp.

A collections team running a single reminder journey can email each customer from the brand address for that customer's region and place the follow-up call from a number matching the recipient's area code. A single journey flow handles the full set of sending addresses.

Dynamic source addresses are available in journey flows in the following AWS Regions: US East (N. Virginia), US West (Oregon), Africa (Cape Town), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Canada (Central), Europe (Frankfurt), and Europe (London).
