First, identify the stages where email users can receive messages repeatedly based on their interval time.
Enable a minimum of 4-5 email templates in each stage with a variation of subject lines, hero copy, body content, and call to actions for template and subject line testing.
Every user has their own predictive interval time in days. This determines how often a user should receive a Cortex stage email. The interval can change day-to-day depending on the user's behavioral patterns on site, email, and mobile app.
Here is an example of a user receiving multiple Ready to buy emails over a period of time.
User Flow: On the first RTB send, user may have a 6 day interval time but as they exhibit higher engagement, the interval time gets smaller. Hence they receive the third RTB email 4 days after the second, and the fourth RTB email 3 days after the third.
If users show little to no engagement, they will eventually fall into At risk and Churned stages disqualifying them from further RTB emails.
This RTB strategy can be applied to other stages where users can receive multiple emails within one Cortex stage.
Second, submit a client request to email@example.com asking to enable dynamic content rotation for email templates.
This setting is not automatically enabled because it is dependent on your business model and dynamic template content.
