Introducing Proactive Message Blocking for Enhanced Efficiency

📥 Overview

We are excited to introduce a new feature that enhances your messaging efficiency by proactively blocking known message-sending failures. This pre-send validation layer effectively prevents messages destined to fail due to factors such as invalid numbers, landlines, or opted-out contacts. By halting these messages before they're sent, you'll save time, reduce costs, and avoid unnecessary confusion.

📊 What's New?

Proactive Blocking of Undeliverable Messages

Messages that would typically result in well-known error codes are now automatically blocked. These include:

• Sending messages to landlines
• Contacts that have opted out
• Invalid numbers and other predictable failures

Smart DND Handling

Contacts that frequently trigger delivery issues—such as responding with STOP or being a landline—are now flagged with Do Not Disturb (DND) markers. This helps prevent future attempts on clearly undeliverable numbers while still allowing retries in temporary situations, such as a phone being switched off.

Clear In-App Feedback

If a message is blocked before it gets sent, you will receive a clear explanation of why it was blocked. This ensures you're not left with uncertainty or guesswork.

🔍 Why It Matters

• Fewer Failed Messages: By avoiding preventable errors, you'll see an improvement in your delivery rates.
• Lower Messaging Costs: Save on credits by preventing unneeded API calls on known failures.
• Increased Clarity: Receive meaningful feedback upfront instead of post-error codes.
• Enhanced Customer Experience: Mitigate the need for support tickets and eliminate guesswork regarding message delivery issues.

⚙️ What This Handles

Here are some examples of messages that the system now blocks:

• Messages to contacts who have opted out
• Attempts to communicate with landlines
• Using a non-SMS-capable sender number
• Messaging prior to completing A2P campaign registration

Additionally, intelligent DND behavior assigns permanent or temporary exclusions based on the failure reason.

📌 Good to Know

• We only block messages when failure is highly predictable or certain.
• In rare cases, such as carrier-specific issues, messages may still be processed through Twilio.
• This feature applies to all messaging platforms, including Conversations, Campaigns, and Bulk Messaging.
