  • Update contact information

    Managing subscriber contact information effectively helps maintain clean lists and enables targeted communication. This guide covers how to update profiles, organize subscribers into groups, and add custom data fields.

    Accessing and Editing Profiles

    Navigate to any subscriber’s profile to view and edit their information. You’ll see their current contact details, group memberships, and any custom fields that have been added.

    Contact Information Updates

    Basic Contact Details

    • Phone Number: Add or edit phone numbers using the “Add Phone” button for SMS campaigns
    • Name Fields: Edit first name and last name as needed
    • Registration Date: View when the subscriber joined (automatically tracked)

    Email Status Monitoring

    The system tracks email delivery status. If you see “BOUNCED” next to an email campaign, it means the email address is invalid or undeliverable. Update these addresses promptly by adding the correct ones as a new subscriber to maintain list quality.

    Group Management

    Groups help you organize subscribers for targeted campaigns and better list management, which you can always change around to your liking and how you would want to organize your subscribers and you can add them to groups via these steps through their contact information:

    • Open the subscriber’s profile page
    • Locate the groups section with the dropdown menu
    • Select one or multiple groups from the available options
    • Subscribers can belong to multiple groups simultaneously
    • Save your changes

    Groups allow you to segment your audience for more relevant messaging and campaign targeting.

    Custom Fields

    The “Add custom field” feature is one of the most powerful tools for collecting additional subscriber information beyond standard contact details. The types of information are endless, such as:

    • Demographics: Age, location, occupation, income level
    • Preferences: Communication frequency, content interests, preferred contact method
    • Business Information: Company name, job title, industry, company size
    • Behavioral Data: Last purchase date, engagement level, website activity
    • Personal Interests: Hobbies, lifestyle preferences, event attendance

    Creating and Managing Custom Fields

    • Navigate to the custom fields section in the subscriber profile
    • Click “Add custom field”
    • Name your field descriptively
    • Choose the appropriate data type (text, number, date, etc.)
    • Enter the information for that specific subscriber
    • Save to update the profile

    Best Practices

    Data Quality Maintenance

    • Address Bounced Emails: Regularly update or remove contacts marked as bounced
    • Verify Information: Double-check email addresses and phone numbers before saving
    • Consistent Formatting: Use standard formats for dates, names, and other data
    • Regular Reviews: Periodically audit subscriber information for accuracy

    Effective Segmentation

    • Strategic Grouping: Assign subscribers to groups that reflect their interests or status
    • Multiple Group Assignments: Use multiple groups to create detailed subscriber profiles
    • Custom Field Strategy: Design custom fields that support your specific marketing goals
    • Test Before Broadcasting: Always use test groups to verify campaigns before sending to your entire list

    Privacy and Compliance

    • Ensure you have permission to collect and store the information you’re adding
    • Keep sensitive data secure and follow relevant privacy regulations
    • Allow subscribers to update their own information when possible via forms

    Troubleshooting Common Issues

    Bounced Email Addresses

    • Check for typos in email addresses
    • Verify the domain exists and is accepting email
    • Consider alternative contact methods to confirm correct information

    Group Management

    • Ensure subscribers are in relevant groups for their current status
    • Remove inactive subscribers from time-sensitive notification groups
    • Use descriptive group names to avoid confusion

    Custom Field Organization

    • Plan your custom fields before creating them to avoid duplication
    • Use consistent naming conventions across all custom fields
    • Regular cleanup of unused or outdated custom fields

    Conclusion

    Proper contact management through regular updates, strategic group organization, and thoughtful use of custom fields will improve your campaign effectiveness and subscriber engagement. Keep profiles current, use groups to segment your audience effectively, and leverage custom fields to create more personalized communication strategies.

    Step-by-Step Setup

    Step 1: Create Your Form

    • Navigate to Forms in your dashboard
    • Click Create new form
    • Choose your desired design from the available templates
    • Add your form fields (name, email, message, etc.)

    Step 2: Configure Group Settings

    • Go to Settings → Groups

  • Groups vs segments

    In Sender, you can organize subscribers with Groups or Segments. Each has a different purpose, and knowing the difference helps you manage your audience effectively.

    What Are Groups?

    Groups are static lists of subscribers that you create manually.

    • Manual membership: You add subscribers to a group during import or later by editing their profile.

    • Doesn’t change automatically: Subscribers remain in the group until you remove them.

    • Multiple groups allowed: One subscriber can belong to more than one group.

    What Are Segments?

    Segments are dynamic subscriber lists created with rules and conditions.

    • Automatic membership: Subscribers join or leave a segment based on whether they meet the conditions you set.

    • Updates daily: The system refreshes segments so they always reflect the latest subscriber data.

    • Flexible rules: You can combine multiple filters, such as location, activity, or custom fields

    When to Use Each

    • Use Groups when you want full manual control over who belongs to a list (e.g., tagging event attendees).

    • Use Segments when you want your list to update automatically (e.g., targeting active buyers or re‑engaging inactive subscribers).

    By combining both, you can keep your subscriber management simple and powerful: use groups for organization, and segments for smart targeting.

    That’s it!
