Subscriber Groups

A subscriber group is a collection of subscribers. By default, newsletters are sent to all subscribers in an account. Groups allow targeted selection for newsletter delivery.

Basics​

A group has:

  • ID - A unique ID
  • Name – A unique name
  • Type – Defines how subscribers are added to the group

Group types​

There are three types of subscriber groups:

Account 1 (Customer A)
│
├─ Group 1: "VIP Customers" (Type: Static)
│  └─ Subscribers are added manually
│
├─ Group 2: "Active Subscribers" (Type: Dynamic)
│  └─ Subscribers based on conditions (e.g. activity = high)
│
└─ Group 3: "CRM Import" (Type: External)
   └─ Subscribers are managed from an external source

Static (Type 1)​

Subscribers are added to or removed from the group manually in the UI or via the API.

Dynamic (Type 2)​

Subscribers are added automatically based on conditions. Conditions can be based on:

  • Subscriber fields (e.g. age, gender)
  • Customer-specific fields
  • Behavior (e.g. last open)

External (Type 3)​

Subscribers are managed from an external source. Subscribers in this group usually cannot be edited in mail2many.

Permissions​

For external groups created via API, permissions can be defined:

  • Edit group – Can users change the group name?
  • Delete group – Can users delete the group?
  • Assign subscribers – Can users add/remove subscribers to/from the group?

These settings help protect external groups from accidental changes in the UI.

Multiple memberships​

info

Important: An account can have multiple groups. A subscriber can belong to multiple groups. A subscriber receives a newsletter only once, even if included in multiple target groups of the newsletter.

Example of multiple memberships:

Account 1
  ├─ Subscriber A (max@example.com)
  │    ├─ Member of: Group "VIP Customers"
  │    ├─ Member of: Group "Active Subscribers"
  │    └─ Member of: Group "Newsletter-EN"
  │
  ├─ Subscriber B (lisa@example.com)
  │    ├─ Member of: Group "Active Subscribers"
  │    └─ Member of: Group "Newsletter-EN"
  │
  └─ Newsletter sent to "VIP Customers" + "Active Subscribers"
       ├─ Subscriber A: Receives newsletter 1x ✓
       └─ Subscriber B: Receives newsletter 1x ✓
