A mailing list is a group of people’s contact details (usually email addresses) that you send the same message to all at once, using one list name instead of typing every address individually.

Basic idea

  • A mailing list is a collection of email addresses (and sometimes names or other contact info) managed together as one group.
  • You send your message to a special list address, and the system forwards it automatically to every subscriber on that list.

What it’s used for

  • Sharing updates like newsletters, product announcements, blog posts, or event information with subscribers who chose to receive them.
  • Keeping a community, customer base, or fanbase informed and engaged over time with relevant news, offers, or discussions.

Main types of mailing lists

  • Announcement list: One-way; only the owner or a small team sends messages (typical for newsletters and marketing).
  • Discussion list: Two-way; subscribers can reply and their messages are distributed to everyone on the list, like a group conversation via email.

How mailing lists are managed

  • Lists are usually handled by specialized software or online services that manage subscriptions, handle unsubscribes, and prevent you from having to update addresses manually.
  • These tools often provide analytics (like open rates and click rates) and help with privacy and anti-spam rules compliance.

Quick example

  • An author, business, or community group collects email addresses from people who opt in (for example, via a signup form), stores them in a mailing list, and then sends a regular newsletter or update to everyone in that list with a single send.
