Super Intelligent SenderYour Gmail mailboxes keep hitting their sending limit
Google caps every account. Cold outreach should stay far below the cap, spread over the day and over several mailboxes.
How many emails can a Google Workspace mailbox send per day?
Google documents a limit of 2,000 messages per user per day for Google Workspace, and 500 for trial accounts. A mailbox that goes over it can be blocked from sending for up to 24 hours. Cold outreach usually runs well below it. In Super Intelligent Sender each mailbox has its own daily and hourly limit, sends are paced through the hour, and a campaign can send from several mailboxes so no single one carries the load.
Signs you have this problem
- Google bounces your own emails with a "limit exceeded" message
- A mailbox stops sending for the rest of the day
- Everything goes out in the first hour of the campaign window
- One mailbox does most of the sending while others sit idle
What Super Intelligent Sender does about it
Your own limit per mailbox
Set a daily and an hourly limit for each mailbox, well under Google's cap.
Rolling windows
Limits count the last 60 minutes and the last 24 hours, not the calendar day, so there is no midnight rush.
Ramp-up for new mailboxes
Start low and step up each day toward a target you choose.
Several mailboxes per brand
Connect more mailboxes to a brand and its campaigns spread new leads across them, in proportion to each mailbox's daily limit.
Live usage
The Mailboxes screen shows sends in the last hour and day against each limit.
What Super Intelligent Sender does not do
Super Intelligent Sender does not raise Google's limits or rotate through mailboxes you have not connected. The limits you set in Super Intelligent Sender are yours to choose; Google's own limits always apply on top.
