Monitoring dashboard

Guardrails, lanes, and queue. Sending domains and warmup live under Settings. We pause sending when metrics go out of range.

Operational guardrails (last 7 days)

We auto-pause when bounce ≥2% or complaints ≥0.1%. Deferrals are a throttle signal.

Targets: bounce <2%, complaints <0.1%. If out of range, fix list or copy then resume.

Deliverability trend

Run node scripts/monitor/aggregate-events.js (e.g. daily) to append to history. Last 30 points shown.

Per-recipient-domain lanes (today)

Keep Gmail / Outlook / Yahoo under ~5–20/min each.

Testing: Simulate webhook event

Pretend a delivered, bounced, or complaint event happened for an outbox message. Useful to test guardrails and suppression without sending real mail.

Guide: limits, warmup, throttling

Inbox limits – Gmail, Outlook, Yahoo throttle by per-IP and per-domain reputation. Use shards (m1.x.com, m2.x.com) so no single domain looks bursty.

Safe rates: New 20–200/day → Warmed 500–2k/day → Strong 5k–20k/day. Per-recipient: Gmail 5–20/min, Outlook 5–15/min, Yahoo 5–10/min.

Warmup: Day 1: 20–50, Day 7: ~300, Day 30: 3k–5k. We ramp based on the schedule; keep bounce & complaints in range or we pause.

Want to send more? (Scale up)

Campaign sending is limited by each sending domain’s daily cap (and warmup when enabled). To send more:

Add sending domains – Each domain (e.g. m1.yourbrand.com, m2.yourbrand.com) has its own cap. Add them in Settings; you’ll need a VPS or subdomain and correct DNS for your mail stack.
Warm them up – Use “Start warmup” so we ramp the cap day by day. Then “Advance day” as you go, or run a daily job to advance.
Arm sequences with a domain – In Sequences, when you add leads to a sequence, choose a sending domain so the queue stays within that domain's cap.
