Microsoft Advertising Audience Network Build a custom audience using LinkedIn or Bing Ads. Target Hotmail/Outlook users based on interests, location, and demographics—without ever seeing their email addresses. 2. Lead Generation Forms (Native) Use Typeform or Google Forms with email validation turned on. Ask users: "Do you prefer Hotmail?" and segment them automatically. 3. Outlook.com API (OAuth) If you’re building an app, use Microsoft Graph API to let users share their email address with permission. This gives you validated, real-time data. 4. Partnership with Bulk Email Services Platforms like Mailchimp, SendGrid, or AWeber maintain their own validation tools. They remove bounces before you even see them.
