What Is a Daily Limit?
A daily limit is the maximum number of emails your campaign will send in a single day. Once that limit is reached, Prospi pauses sending for that day and automatically resumes the next day during your scheduled sending window.
This applies to all emails in the campaign - initial outreach and follow-up steps combined.
Why Daily Limits Matter
Sending too many emails too quickly is one of the fastest ways to damage your sender reputation. Email providers monitor sending patterns closely. A sudden spike in volume triggers spam filters, increases your chances of landing in the junk folder, and can get your domain flagged.
Daily limits keep your sending pattern consistent and natural - exactly what inbox providers want to see.
How to Set Your Daily Limit
Open your campaign and go to the Schedule step
Find the Daily sending limit field
Enter your maximum emails per day
Save your settings
Note: The limit is split across all sending accounts assigned to the campaign. If you have 3 accounts and a limit of 30, each account sends approximately 10 emails per day.
Recommended Limits by Account Age
The right daily limit depends on how warmed up your sending accounts are:
0-2 weeks (new accounts): 0 emails per account per day
2-4 weeks: 5-15 emails per account per day
1+ months (established): 20 emails per account per day
The safest way to scale volume is to add more sending accounts rather than pushing individual accounts to their limits. 3 accounts at 30 emails/day is safer than 1 account at 90 emails/day.
What Happens When the Limit Is Reached
Sending stops for the rest of that day
No leads are skipped - they stay in the queue
Sending automatically resumes the next day at the start of your sending window
Best Practices
Start conservatively - it is easier to increase than to recover from a damaged reputation
Use multiple sending accounts to scale volume safely
Monitor campaign analytics weekly for signs of deliverability issues
Reduce limits immediately if bounce rates rise or open rates drop
Pro tip: The 10 emails per account per day rule is a solid default for new accounts in the first two weeks. It matches the warmup rate, so inbox providers see a smooth, consistent pattern rather than a sudden jump.
