Outbound drip (throughput control)

Drip slows outbound traffic so WhatsApp sees a steady pace instead of bursts. In the current product it is a fixed pattern: one message per interval; you only configure the interval length (how many milliseconds between consecutive sends for that sub-account).

Where to configure​

  1. Sub Accounts → open the sub-account → Connection tab.
  2. Find Drip control (or the drip card next to n8n / proxy on the same tab).
  3. Set Duration (ms) — minimum 2000 ms (2 seconds) in the app today; higher values mean slower sending.
  4. Save drip settings.

The maximum messages per interval field is fixed by the system (always one-at-a-time in this mode).

When to use it​

  • You need gentler outbound behaviour for a hot number or a new session.
  • Campaigns should not hammer WhatsApp with back-to-back API sends from the same sub-account.
  • Your agency asks you to align with a specific pacing policy.

Good practices​

  • Start with a conservative interval and adjust after observing delivery and session health.
  • Drip affects outbound queuing for that sub-account; it does not replace session routing — you still choose which line sends via Outbound session selection.
  • If outbound feels “stuck”, confirm whether drip was recently tightened and review queue depth with your team.
