Mailing lists, subscribers, segments, and campaigns in the account they connected.

Connecting Moosend in practice

Moosend rate-limits per endpoint rather than per account, and the bulk variants are tighter than the single-record ones: adding subscribers one at a time allows ten calls per ten seconds while subscribe-many allows two, and deleting one at a time allows forty while delete_many allows eight. Batching therefore reduces throughput here, which is the opposite of the assumption most integrations are built on.

Scopes that draw scrutiny

  • API key (account-wide) One key per account, found under More > Settings > API key, with a Generate new API key button to rotate it. There is no scoped or read-only form.

Rate limits

  • Campaign statistics, GET /campaigns/{id}/stats/{Type}: 2 calls per 60 seconds — the tightest limit in the API.
  • Add subscriber, POST /subscribers/{listId}/subscribe: 10 calls per 10 seconds. Add many, subscribe-many: 2 calls per 10 seconds.
  • Delete subscriber: 40 calls per 10 seconds. Delete many, delete_many: 8 calls per 10 seconds.
  • Unsubscribe from an account, a list, or a list and campaign: 20 calls per 10 seconds each.
  • Send a transactional campaign, POST /campaigns/transactional/send: 6 calls per second.
  • Over the limit the body carries {"Code": 429, "Error": "RATE-LIMITING"}.

Worth knowing

  • Only account owners and admins can see the API key. Moosend states that other permission levels "will see all 0’s in place of the key", so a non-admin copies zeros and the integration fails looking like a bad credential rather than a permissions problem.
  • Limits are per API key, so a second integration on the same account competes for the same per-endpoint budgets.
  • Campaign statistics at two calls a minute rules out any design that polls for delivery results.

Acts as the person, not as itself

Each user connects their own account. Every call carries both identities — the agent and the person it is acting for — so the agent can never reach past what that individual can already do.

Credentials never touch the agent

Tokens live in the vault and attach server-side at call time. The agent holds a session, not a secret, and revoking access does not mean rotating a key.

Every call on the record

Who asked, which agent acted, which action ran, and the verdict that let it through — one audit trail across every integration, not one per vendor.

What an agent can do

Each action is granted on its own. An agent allowed to read is not thereby allowed to write, and the scope beside each row is what the acting user must have connected for it to run at all.
