Creating A Distribution List In Outlook In 2026

An Outlook distribution list – also called a Contact Group – is a saved collection of email addresses that functions as a single recipient, letting you send emails to multiple contacts simultaneously without entering addresses individually. Distribution lists are available in all Outlook versions, including Outlook 365 (web), Outlook for Windows, and Outlook for Mac, at no additional cost.

Distribution lists and professional email signatures solve two different sides of the same problem: getting your emails to the right people, looking the right way. Once your distribution lists are set up, make sure every message you send to them carries a professional Outlook signature. HubSpot's Email Signature Generator creates clean, validated HTML signatures built specifically for Outlook — so your signature renders correctly for every recipient on your list, regardless of whether they're reading in Gmail, Apple Mail, or another email client, without the formatting issues that commonly result from pasting AI-generated or manually coded signature HTML into Outlook's signature editor.
