Can we send bulk emails from outlook

Published November 1, 2024 · Updated July 18, 2026 · Bulk Email

Can we send bulk emails using Outlook? For a modest contact list, yes - but Outlook and its account limits make it a poor tool for genuine campaigns. Here is what is realistic and where the boundaries are.

What Outlook can do

You can BCC a contact group, or use Word mail merge with Outlook to personalise each message. Both work within your account's daily send limit - roughly 10,000 recipients on Microsoft 365, far fewer on free Outlook.com.

Where it breaks down

• No dedicated IP or deliverability control.
• No analytics or list management.
• Throttling and account risk past the limits.
