<p>Data silos are arguably the biggest obstacle to effective cross-channel marketing. When your email marketing, text messaging, point-of-sale (POS) system, loyalty program, ecommerce store, and customer service data live in separate systems, you end up with a disconnected and incomplete view of customer interactions across channels. </p>

<li><strong>Flows:</strong>Route customers down different paths in an automated flow based on their channel affinity. For example, if the subscriber’s top channel is email, set the logic to check a customer’s channel affinity and send them down a “Yes” path for email and a “No” path for SMS. For the “No” path, or after a time delay, send a follow-up text message. This way, you prioritise a specific channel without excluding others-creating a coordinated cross-channel experience.</li>
