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.
