What is a distribution list?
A distribution list (also called an email group, mailing list, or contact group) is a collection of email addresses grouped under a single name or address. Instead of manually typing 20 email addresses every time you need to reach your team, you send to the list and everyone receives it.
Distribution lists exist in many forms — from simple contact groups in Gmail or Outlook to managed organizational groups in Google Workspace and Microsoft 365. The right choice depends on your use case, scale, and whether you need features like moderation or analytics.

What is an email distribution list?
An email distribution list is a group of email addresses collected under a single name or address. Instead of typing multiple addresses every time, you send to the list and everyone on it receives the message. Distribution lists come in many forms — from simple contact groups in Gmail to managed organizational groups in Google Workspace and Microsoft 365.
The term "distribution list" is used loosely in the email world. It can refer to a contact group in Outlook, a Google Group in Workspace, a traditional listserv, or even a subscriber list in an email marketing platform. Each type has different capabilities and use cases.
Types of distribution lists
- Contact Groups: Personal address groups saved in your email client (Gmail labels, Outlook contact groups). Simple, private, limited to ~20 addresses.
- Email Groups: Organizational groups with a shared address (team@company.com). Managed by admins in Google Workspace or Microsoft 365.
- Mailing Lists: Self-service lists with subscription management and moderation (listservs, Google Groups). Good for communities and large organizations.
- Marketing Lists: Subscriber lists managed by an ESP like Sequenzy. Include analytics, templates, segmentation, and compliance features.
- BCC Distribution: Simple one-off sends with all recipients in BCC. No setup needed, but no features either.
When to use a distribution list vs. an ESP
Use distribution lists for internal team communication, small groups, and two-way discussions. Use an ESP (Email Service Provider) when you're sending to external subscribers, need tracking and analytics, require compliance features, or want professional templates and automation.
If you're ready to move beyond simple distribution lists, Sequenzy makes it easy to manage subscriber lists with full segmentation, automation, and analytics — while staying compliant with GDPR and CAN-SPAM.
