mailerpress/set-default-list marks a list as the site default. Every subsequent opt-in that arrives without an explicit list target is added here.
Only one list can be the default; the previous one is demoted automatically.

How it works
The default list is where unrouted signups accumulate, which on most sites means the majority of them. A form without a list target, an embed without one, an integration that does not specify — all of them land here.
So changing the default redirects the flow of new subscribers, immediately and silently. Existing contacts are unaffected; only future signups move.
That produces a specific kind of confusion: a site that changed its default months ago has two lists, one growing and one static, and nothing says why.
The automatic demotion means there is never a gap and never two defaults, which is the right behaviour and means the change is a single call rather than two.
Idempotent.
Input
| Name | Type | Required | What it is |
|---|---|---|---|
id | integer | Yes | The list to make default. |
What comes back
| Name | Type | What it is |
|---|---|---|
list | object | The new default list. |
success | boolean | Whether the call completed. |
message | string | A one-line summary of what happened, suitable for showing a human. |
error_code | string | Present only on failure — a stable machine-readable reason, such as a missing field, a wrong field type or an unmet confirmation. |
Example
Ask your assistant:
Make the newsletter list the default.
It resolves to one call:
{
"ability": "mailerpress/set-default-list",
"parameters": {
"id": 3
}
}Worth knowing
- Redirects future signups only. Existing contacts do not move.
- The previous default is demoted automatically.
- A site that changed this has one growing list and one static one.
- Idempotent.
