Smart Jitter & Human Send Pacing
Automated outreach that looks completely human to mail servers. OutSends introduces randomized delay intervals (Smart Jitter) between outgoing emails, eliminating the robotic, predictable spikes that spam algorithms look for.
How it works
Get started with smart jitter sending in a few simple steps.
Set your sending window
Choose active sending hours (e.g., 9:00 AM to 5:30 PM) and time zones tailored to your prospect audience.
Define jitter intervals
Configure min and max delay ranges (e.g., 25s to 65s) to randomize time gaps between consecutive messages.
Enable account rotation
Stagger sends across multiple connected accounts so no mailbox sends rapid bursts.
Monitor dispatch queue
Watch your real-time outbox dispatch safely and steadily throughout the business day.

Frequently asked questions
What is Smart Jitter?
Smart Jitter is a dynamic delay algorithm that adds random seconds between outgoing emails instead of firing at fixed, robotic intervals like every 30.0 seconds.
Can I set specific sending hours?
Yes. You can restrict your campaign sending schedule to business hours in any time zone (e.g. 9:00 AM to 5:00 PM EST, Monday through Friday).
Does OutSends impose artificial daily caps?
No! OutSends has zero artificial daily sending caps. Your volume is governed only by your monthly plan quota and your mailbox pacing limits.
