# Deliverability & compliance

Some channels, such as SMS/MMS, Email, and Voice, are subject to specific rules and regulations.

These rules and regulations are often region or country-specific and have a direct impact on the chances of your messages being delivered to recipients.

In some situations, countries and regions have laws in place to protect their citizens, which you must follow if you want to send messages to recipients in that area.

By following the guidelines in this section, you can ensure that you're staying compliant, protecting the privacy of your customers, and maximizing the chances of your messages reaching your recipients.
