description: >-
  Messente applies fair-use throttling to its REST API to protect delivery
  quality and downstream carriers. Sustained request throughput and messaging
  send rate (messages per second) are governed per account and can be raised for
  high-volume senders on request. Bulk sending is designed to be submitted via
  the bulk Omnimessage endpoint rather than many concurrent single-message
  calls. Specific numeric limits are not published as fixed public values and
  are set per account.
notes: >-
  Confirm current per-account throughput and messaging throughput limits with
  Messente support or in the dashboard during reconciliation; high-volume send
  rates are negotiated. Honor HTTP 429 responses with backoff.
