Apple's upcoming iOS 26 release (expected in September) has generated significant discussion in political circles, with organizations raising concerns about potential impacts on voter outreach and fundraising efforts. As the September release approaches, we're providing a factual overview of what's actually changing and what it means for political campaigns, nonprofits, unions and advocacy organizations.

‍

What iOS 26 Actually Changes

The "Screen Unknown Senders" Feature

iOS 26 introduces an updated version of a filtering feature that has existed since iOS 13. Previously called "Filter Unknown Senders," the feature is being renamed to "Screen Unknown Senders" and includes interface improvements that make filtered messages more accessible to users.

Key Facts:

• The feature remains opt-in by default - users must actively enable it
• Messages are filtered based on two simple criteria: the sender is not in the user's contacts AND the user has never replied to that sender before
• Filtered messages go to an "Unknown Senders" category, not "spam" - they are treated differently from actual spam messages

‍

Improved User Interface

The main improvement in iOS 26 is visibility. The filter button in the Messages app will now display a blue badge showing the number of new texts from unknown senders, making it easier for users to notice and access these messages when they want to check them.

‍

Current State of the Industry

According to Apple's direct clarification to Fast Company, the "aggressive message filtering" described in political memos has actually existed in similar form since iOS 13, and the iOS 26 changes may actually make it easier for users to see filtered messages rather than harder.

The feature is only automatically enabled in iOS 26 if users upgrade from iOS 18 and already have message filtering enabled. For new users or those who haven't previously used filtering, it remains an opt-in feature.

‍

What's Not Changing

• The criteria for determining "unknown senders" remains the same
• Time-sensitive messages like two-factor authentication codes are designed to bypass filtering
• A sender is considered "unknown" if it meets these two criteria: The sender has not been added to your contact list AND you've never responded to a text message from the sender 
• Political messages that are not in user’s contacts are not classified as "spam" but as "unknown senders," which is a separate and less restrictive category

‍

What Is Changing

• Better user interface for accessing filtered messages
• Visual notifications when unknown sender messages arrive
• More granular controls for users who choose to enable filtering

‍

Beyond Politics

The changes affect more than political campaigns - nonprofits, advocacy organizations, and unions using SMS for outreach may also need to adapt their strategies.

‍

Looking Ahead

Timeline and Adoption

• iOS 26 Expected Release: September 2025
• Bulk Adoption Predicted: December 2025 when people receive new phones for the holidays

‍

Strategic Recommendations

1. Diversify Outreach Methods: Don't rely solely on one channel
2. Invest in Relational Organizing: Build volunteer networks for personal outreach
3. Educate Supporters: Encourage supporters to save campaign numbers to their contacts and/or respond back to your text outreach

‍

The Bottom Line

While iOS 26 introduces interface improvements to message filtering, it doesn't fundamentally change how unknown sender filtering works. The feature remains opt-in, and Apple has actually made filtered messages more visible to users who choose to enable filtering.

Organizations that adapt by prioritizing personalization, trust, and authentic engagement will be best positioned to maintain effective communication with their audiences.

Stay Updated: We'll continue monitoring developments around iOS 26 and provide updates as new information becomes available.
