CAN-SPAM compliant
All emails include required elements to help you follow CAN-SPAM regulations
Subscription groups are a powerful tool for organizing your email content into categories that subscribers can choose from. They work alongside Audiences (which are for targeting) to give you a complete contact management system.
Subscription Groups vs. Audiences
Brew offers two powerful ways to organize your contacts, each serving a distinct purpose in your email marketing strategy. Understanding when to use subscription groups versus audiences will help you create more effective campaigns and give your subscribers a better experience. Subscription Groups- Visibility: Visible to subscribers in the Preference Center
- Quantity: Usually have 3-5 groups (e.g., “Weekly Newsletter,” “Product Updates”)
- Control: Subscribers choose which groups they want to join or unsubscribe from
- Purpose: Used for broad content categories
- Visibility: Internal only, not visible to subscribers
- Quantity: Can have many different segments
- Control: You define and manage them
- Purpose: Used for targeted sending based on behavior and properties
Creating a Subscription Group
1
Access subscription groups settings
- Go to Settings in the main navigation
- Select Subscription Groups
2
Create a new group
Click the Create a group button in the bottom right corner to start creating a new subscription group.

3
Configure group details
Fill in the details for your new subscription group:
- Name: A clear, descriptive name for the group (e.g., “Weekly Newsletter”)
- Description: Explain what subscribers will receive (shown in the Preference Center)
- Color: Brew will automatically choose a color for your subscription group
Use clear, benefit-focused descriptions that help contacts understand what they’ll get by subscribing to each group. For example, “Get weekly tips and insights to improve your marketing strategy” is more compelling than “Marketing newsletter.”

How Brew Handles Unsubscribes
Brew automatically manages the entire unsubscribe process for you, ensuring compliance with email regulations while maintaining a good relationship with your audience.Automatic Unsubscribe Handling
When you send emails, Brew automatically:- Adds legally required unsubscribe links to all marketing emails
- Processes unsubscribe requests immediately when clicked
- Directs users to your Preference Center for a better experience (if you have created one)
- Skips unsubscribed contacts when sending campaigns or automations
- Still delivers transactional emails (like password resets or order confirmations)
How Unsubscribes Affect Different Email Types
Email Type | Effect of Unsubscribe |
---|---|
Campaigns | Unsubscribed contacts are automatically skipped |
Automations | Unsubscribed contacts are automatically skipped |
Transactional Emails | Always delivered regardless of subscription status |
Transactional emails are still delivered to unsubscribed contacts because they contain essential information directly related to individual transactions or account activity, not marketing content. This approach complies with CAN-SPAM regulations, which permit sending transactional emails to people who have unsubscribed from marketing communications.
Viewing Unsubscribed Contacts
Maintaining a clean contact list is essential for good deliverability. Brew makes it easy to view and manage contacts who have unsubscribed from your emails:1
Navigate to the Audience page
Go to the Audience tab in the main navigation menu.
2
Filter for unsubscribed contacts
- Click on the Filter field at the top of the audience table
- Write out your filter - in this case: “Unsubscribed contacts”
3
Review unsubscribe details
Click on any contact in the filtered list to see:
- When they unsubscribed
- Which subscription groups they’ve opted out of
- Their subscription history timeline
4
Save unsubscribed audience
If you save this audience, you can easily keep track of your unsubcribed contacts going forward. Just make sure to never email this audience as the emails will not be delivered due to the contacts being unsubscribed.
Regularly reviewing your unsubscribe data is a good practice for maintaining audience health. Look for spikes in unsubscribes after specific campaigns to identify content that may not be resonating with your audience.
