Mailing lists — auto and custom
How auto-managed and custom mailing lists work, and who can post to which.
A mailing list is an email address that forwards to a group of people. Members can email it from any inbox and the message goes out to all recipients.
Lists live at addresses like all@yourtroop.mytroop.org or bears@yourtroop.mytroop.org.
Auto-managed lists
These exist automatically and you can't delete them. Their recipients are kept in sync with the troop roster. Example: all@… always goes to every active member.
You can edit:
- The description (helpful so members understand what it's for).
- The Who can post setting (see below).
You cannot edit who receives auto-managed lists — that's the whole point. They're maintained for you.
Leadership positions get auto-managed lists too, such as spl@… and treasurer@…, which follow whoever holds the position.
Custom lists
Create custom lists for any subset of members — a den, a committee, parents of a specific cohort, etc.
Addresses starting with event- are reserved: each event has its own group address, described in
Emailing everyone going to an event.
In Admin > Communication > Mailing Lists > Add list:
- Address — choose the part before
@. Lowercase letters, digits, and hyphens work best. An address another list uses, or one your roster claims automatically (likeleadersor a den name), can't be used. - Description — optional but recommended.
- Who can post — see below.
- Who receives — all members, specific people, or other lists. See Recipient targeting.
Click Save to create the list.
Renaming a list
Tap Edit on a custom list and change its address. Auto-managed lists can't be renamed.
Mail sent to the old address keeps arriving, so nothing is lost when someone replies to an old thread. It goes out under the new address. The old address stays reserved for this list, and shows under Old addresses that still work when you edit it. Tap Remove and save when you want to stop it working and free it up.
"Who can post" options
| Option | Who can send to this address |
|---|---|
| All registered members | Any active member of the troop. (Default for most lists.) |
| Leaders only | Members with leader-level role or higher. |
| Anyone (public) | Anyone on the internet, including people without an account. |
The public option is dangerous — anyone who learns the address can email your whole list. MyTroop shows a warning when you select it. Use this only for "contact us" style addresses you'd put on the public site, and consider a separate inbox or moderation downstream.
A list built from other lists can't be more open than any list inside it. See Lists made of other lists.
What members see
Members can find list addresses on the Mailing Lists page (linked from Pages) and on the Communication settings page if they're admins. Replies to a list message go back to the list — be aware your message will be visible to every recipient.
Attachments
Photos and files attached to a message go out with it, up to 25 MB and 20 files per message. See Sending attachments.
