listmonk never derives a plaintext part from HTML/Markdown on its own
(models/campaigns.go only compiles AltBodyTpl, and
internal/manager/message.go only emits text/plain, when altbody is
explicitly non-null) -- confirmed against the deployed v6.2.0 source.
Every campaign this tool created was HTML-only as a result, contrary
to the README's now-corrected claim.
Reusing the same raw Markdown+template source as altbody personalizes
it identically to body, since AltBodyTpl compiles whenever the text
contains {{ }} expressions.

Discovered while verifying the TestCampaign fix against real listmonk:
create/update apparently default an omitted messenger to "email"
server-side, but the test-send endpoint validates the raw request body
without that same defaulting, failing with "Unknown messenger .".
eec-campaigns only ever targets email, so send it explicitly instead
of depending on an inconsistency between endpoints.

listmonk's /api/campaigns/:id/test handler binds the request into the
same campReq struct create/update use and validates it in full, so a
request with only {"subscribers": [...]} fails with "Invalid length
for name" before subscribers is ever read. TestCampaign now sends the
campaign's full CampaignInput alongside subscribers.

Answers "can the unsubscribe template be added via git+API too": commit
listmonk's own stock campaign template (already unsubscribe-capable) as
email-templates/campaign.html, add a small find-or-create-or-update
Template client (confirmed against knadh/listmonk's actual model/handlers),
a new `template` subcommand, and a manual-dispatch-only workflow to push it
in as the default campaign template. Unlike campaign sync there's no
draft/live status to protect, so this is always a safe overwrite.
Read knadh/listmonk's actual Go source (cmd/campaigns.go, cmd/subscribers.go)
instead of relying on incomplete public docs. Two corrections: the media
attach field is "media" (plain IDs), not "media_ids" as originally guessed;
and there's a single query-based bulk list action
(PUT /api/subscribers/query/lists) that applies a segment_query server-side,
so resolveSegment no longer fetches subscriber IDs client-side before
bulk-adding them. Create-status-defaults-to-draft and the test-send
"subscribers" field are now confirmed rather than flagged TODO(verify).
Drives listmonk's real Campaign API from git-authored Markdown+frontmatter,
so broadcast/segment emails get listmonk's mature unsubscribe/bulk-send/
attachment handling instead of reimplementing it. sync only ever creates or
updates a draft (idempotent, diff-based, refuses to touch a non-draft
campaign); a pushed send/<slug> tag or manual workflow run is the only way
to actually trigger a send. Includes list-name resolution, segment_query
materialization into managed lists, content-hash-deduped attachment
uploads, and an automatic post-sync preview email.
