We’re excited to introduce Mobile Number Status Validation, a powerful new feature designed to enhance your SMS outreach and improve message deliverability. With this feature, WooSender will automatically check if a phone number is active or inactive before you send a message. Whether you’re uploading contacts into WooSender, updating a contact's number or sending your first SMS, you’ll have real-time validation to ensure you’re reaching active numbers only.

✅ Boost SMS deliverability – Ensure your messages are sent to active numbers.

✅ Lower error rates – Avoid failed messages by verifying numbers in advance.

✅ Improve engagement – Reach contacts who can receive and respond to your SMS.

Go to Settings ➡️ Account Info ➡️ Contact Validator ➡️ Toggle On Mobile Number Status Validation.

To turn on the Mobile Number Status Validation toggle, you will need to first make sure the Phone Number Type Validation is turned ON.

When the Mobile Number Status Validation feature detects the number uploaded into WooSender is active, a green M will show up next to the number. (Like below)

When the Mobile Number Status Validation feature detects the number uploaded into WooSender is inactive, a red M will show up next to the number. (Like below)
