Double-Check Marketing Opt-Ins and Opt-Outs

Marketing preferences—such as email, SMS, telemarketing, and direct mail—are typically represented as boolean values (true/false). These booleans determine whether a contact has opted in or out of receiving specific types of communication. However, differences in how applications interpret these preferences can lead to confusion and costly errors:

Opt-In vs. Opt-Out Misinterpretations

If a boolean value is incorrectly flipped during integration, individuals who opted out may receive unwanted communications, violating spam laws. Conversely, contacts who opted in might stop receiving the messages they want, impacting engagement and business goals.

Key Actions

• Understand how both source and target applications represent and handle marketing preferences.

• Map preferences correctly during data transformations.

• Regularly validate integrations against the specifications of each platform.

Implement Peer-Review Processes

Even experienced developers can overlook critical details. A peer-review process helps catch bugs, enforce best practices, and ensure integrations behave as expected.

How Middle Supports Peer Review

• Middle provides user access levels within standard accounts and ENTERPRISE instances. Leverage these features to structure review workflows effectively.

• Encourage collaboration and validation before deploying changes to production.
