A seed address lets you display a preview of your message, send a proof, and test message personalization before email or SMS delivery. Seed addresses are linked to the delivery and cannot be used for other deliveries.
In the transactional message template, click the Seed addresses tab.
Assign a label to it for easy selection later.
Enter the seed address (email or mobile phone depending on the communication channel).
Enter the external identifier: this optional field allows you to enter a business key (unique ID, name + email, etc.) that is common to all applications on your website, used to identify your profiles. If this field is also present in the Adobe Campaign marketing database, you can then reconcile an event with a profile in the database.
Insert test data (refer to Personalization data).
Click the Add other seed addresses link, then click the Add button.
Repeat the process to create as many addresses as you need.
Once the addresses are created, you can display their preview and personalization. Refer to Transactional message preview.
