What is Burst Rate?Burst Rate is the maximum number of messages sent from this number in any single hour window.Safe: under 120 messages/hourCaution: 120–200 messages/hourHigh risk: 200+ messages/hourWhy it mattersEven if your daily volume looks normal, sending too many messages in a short burst is a strong automation signal. Human senders have natural gaps—automation does not.How to improve this metricStagger campaigns over 2–4 hours instead of blasting in 10–20 minutesRandomize send times so messages drip out instead of landing all at onceSplit big sends across multiple numbers so no single line spikesAvoid back-to-back workflows that fire at the same exact timeBest practicesUse schedule windows (e.g. 9am–5pm) and let Blooio distribute sends inside that rangeIf you see repeated high spikes, lower your workflow concurrency or throttle rateCombine this with Daily Messages to keep both per-day and per-hour usage safe.
