Set campaign sending limits

We have a high-volume campaign for the product launch. Limit the send to 10,000 emails per hour and pause after each batch until deliverability checks pass. Start the first batch at 08:00 on Monday. Before each batch releases, check that our sending domain has no new bounce spikes and that the ESP reports healthy engagement the previous hour.

Before I set hourly send limits for the launch, make the plan easy for the head of deliverability to approve: show projected hourly volume, current sender reputation score, and the rationale for 10,000/hour. Flag thresholds that should automatically stop the campaign—bounce rate over 2%, complaint rate above 0.1%, or ISP throttling signs—and recommend a backoff rate if any trigger fires.

We scheduled a product launch with a 10,000/hour cap. Early metrics show engagement higher than expected and limited bounces, but the CEO wants faster reach. I worry raising the cap could trip ISP throttling. What is the likely immediate risk if I double the cap, what quick checks decisively show it's safe, and what is the safest incremental change to propose now?

Across three launches we set conservative per-hour caps and still hit ISP throttling or delayed deliveries. I own campaign pacing and coordination with product. Where am I losing control: inaccurate list hygiene forecasts, inconsistent ISP relationships, or poor early engagement gating? Recommend one habit to stop ISP throttles in the next launch and one team change to reduce this risk permanently.
