# Can I make a subscription opt-in mandatory in campaigns?
## Here's a quick guide on opt-in regulations for engagement campaigns.
When setting up engagement campaigns, it's important to consider privacy laws and regulations that apply to your specific region. Generally, while you can make certain fields mandatory for participation in your campaign, requiring subscription opt-in for marketing communications can be **more complex and may depend on your state or province's legal requirements**.
To comply with anti-spam regulations in various regions, the "Check by Default" option for email address entry will not be automatically selected.
**Before requiring fans to subscribe to complete your campaign, consult with your legal department to ensure compliance with your region's privacy laws.**
Refer to the consumer compliance laws and regulations linked below for review:
