Daily Sending Limits per Sender Mailbox
Protect your email domains from spam heuristics. Set safe daily limits (e.g. 35 emails/day) on each connected sender account with automatic round-robin failover to the rest of your pool once reached.
How it works
Get started with daily sending limits in a few simple steps.
Connect your mailboxes
Add your Gmail, Google Workspace, Zoho, or SMTP sender accounts in the Senders tab.
Configure per-sender daily limits
Set your preferred daily ceiling (recommended: 30 to 40 emails/day per mailbox).
Set up campaign pools
Select which accounts participate in rotation. OutSends calculates total daily campaign capacity automatically.
Automatic failover dispatch
When mailbox A reaches its daily cap, OutSends immediately routes remaining messages to other active mailboxes in your pool.

Frequently asked questions
Why should I limit daily emails per mailbox?
Email providers like Google and Outlook monitor sudden sending spikes. Keeping individual mailboxes under 35–40 cold emails per day ensures pristine domain reputation.
Does OutSends limit my total daily sending?
No! OutSends has zero artificial daily account caps. Your volume is governed only by your monthly quota (e.g. 20K on Starter, 100K on Pro) and your per-sender safety settings.
What happens when a mailbox reaches its daily sending limit?
OutSends automatically pauses sending on that specific account until the next day, seamlessly continuing campaign dispatch through other active accounts in your pool.
