Email List
also called subscriber list, mailing list
The set of contacts who have consented to receive email from a business.
The audience you own.
What It Is
You will find Email List in the Marketing layer, alongside the rest of Channels. Stated plainly: the set of contacts who have consented to receive email from a business.
It is a label with a settled working definition, so the value is in using it the same way every time. Once it is defined that clearly, arguments about it usually stop.
How It's Used
In practice, Email List shows up in campaign planning, channel choices and the reporting that follows them. It is usually discussed together with Email Marketing, Opt-In and Owned Media. The practical test is whether everyone in the room means the same thing by it.
Why It Matters
Email List is one of those items that only becomes visible when it is missing. When it is unclear, spend keeps moving but nobody can say what it bought. It is worth pinning down before anyone builds on top of it.
Think of it as a name on a box. Open the box and this is what is inside: The audience you own.
Termshift™
How the meaning shifts depending on who is using it, and where.
Practitioners use Email List as shorthand and expect no explanation — the set of contacts who have consented to receive email from a business.
Outside the industry, most people would just say: the audience you own.
The Bottom Line
If you only keep one thing about Email List: the audience you own. Everything after that is detail.
