Learning Objective
By the end of this guide, you'll know what the global daily limit is, how to set it up for your sending addresses, how it works across campaigns with first emails and follow-ups, and best practices for maintaining good deliverability.
Why This Matters
The global daily limit protects your email sender reputation and ensures good deliverability. Without limits:
Spam filters flag your account for sending too many emails
Deliverability drops as email providers throttle or block your messages
Your domain reputation suffers, affecting all future campaigns
Setting an appropriate global limit:
Maintains sender reputation by staying within safe volumes
Prevents account suspension from email providers
Ensures consistent delivery to prospects' inboxes
Prerequisites
Before setting your global limit:
You have at least one sending email address connected to lemlist
You have access to Settings → Sending limits to configure limits
You understand your campaigns' sending needs – First emails + follow-ups per day
The mailbox has finished warm-up – a Warmup Score of 90+ plus 14 days of stabilization. No campaign starts under a Warmup Score of 90
You account for your total daily volume per mailbox – warm-up plus campaigns stay at or below 50 emails/day per mailbox
What Is the Global Daily Limit?
The global limit is the total number of emails that lemlist can send in a 24-hour period from a specific sending address, across all active campaigns.
This includes:
✅ First emails (initial outreach to new leads)
✅ Follow-up emails (subsequent steps in your sequences)
💡 Important: Emails sent using lemwarm (lemlist's email warm-up tool) do not count toward the lemlist daily global email limit.
However, for deliverability, you should still manage your total daily volume: warm-up plus campaigns stay at or below 50 emails/day per mailbox.
How to Set Up Your Global Email Limit
Step 1: Go to Settings
From the bottom-left of your lemlist account, click your profile name, then select Settings.
Step 2: Open Sending limits and set your daily limit
In Settings, click Sending limits, choose the sending email address if needed, then set the Maximum number of emails sent by lemlist in 24h for that address (using the +/- buttons).
Step 3: Repeat for additional addresses
If you have multiple sending addresses, set the limit for each one individually.
Example (three mailboxes at full volume):
Email 1: lemlist limit set to 30 emails/day + 10 lemwarm
Email 2: lemlist limit set to 30 emails/day + 10 lemwarm
Email 3: lemlist limit set to 30 emails/day + 10 lemwarm
Each mailbox sits around 40/day total, at or below the 50/day per mailbox ceiling
💡 Important: If your domain is less than one month old, keep the whole domain under 100 emails/day across every mailbox on it combined, then increase gradually.
How Global Limits Work
Example Scenario
Campaign setup:
100 total leads
Schedule set to send 25 first emails to new leads each day
Multiple follow-up steps in the sequence
lemlist global email limit: 30 emails per day (the cap, reached after ramping up from 10–15/day; plus 10 lemwarm, keeping the total around 40/day)
Day-by-day breakdown (lemlist sends only):
Day 1:
Send 25 first emails to new leads
Total: 25 emails
Day 2:
Send 25 new first emails
Send 5 follow-up emails (to leads from Day 1)
Total: 30 emails (hits the 30/day lemlist limit)
Day 3:
Send first emails and follow-ups up to the 30/day limit
Any remaining scheduled emails will be queued and sent later (once the rolling 24-hour window allows)
Global Limit Applies Across All Campaigns
The global limit applies across all active campaigns using the same sending address.
Example (lemlist sends only):
Campaign A: Scheduled to send 25 emails today
Campaign B: Scheduled to send 25 emails today
Total: 50 emails
With a 30 email/day lemlist limit: Only 30 emails will be sent (some emails will be delayed)
💡 Important: There is no prioritization mechanism to favor one campaign over another. Emails are sent based on scheduling configurations and delay settings.
To manage overlaps:
Avoid running simultaneous campaigns using the same address
Or stagger schedules across multiple sending accounts
Reaching Your Daily Global Limit
If you see a message like:
"You've reached your daily sending limit"
This means you've hit the limit for the day.
What this means:
The global limit is applied across all active campaigns
Limit is calculated over a 24-hour period
Remaining emails will queue and send later (once the rolling 24-hour window allows)
Best Practices for Setting Your Global Limit
Three caps, checked in this order. The domain check comes before the mailbox check, and both come before any volume number.
1. Domain under one month old? Keep the whole domain under 100 emails/day, every mailbox on it combined, then increase gradually.
2. Mailbox not yet through 14 days of stabilization? 0 cold emails. lemwarm only, at target. No campaign starts under a Warmup Score of 90.
3. Mailbox out of warm-up, campaigns live? Start at 10–15/day through lemlist per mailbox, add 5 per week, and cap at 25–30/day.
Total ceiling: ✅ warm-up plus campaigns at or below 50 emails/day per mailbox.
Why?
Sending too many emails can negatively affect your deliverability
Increases the risk of your account being flagged by email providers
Gradual sending volume protects your sender reputation
After an incident: restart at about 15/day in lemlist with a ramp increment of 3, and keep both reputation signals running until the mailbox is stable again.
Troubleshooting
Issue: Emails aren't sending even though I haven't reached the limit
Fix:
Check that campaigns are active (not paused)
Verify the sending schedule includes today's time window
Ensure leads are in "Reviewed" status and ready to launch
Check that the lemlist global limit isn't set too low for your campaign volume, while keeping warm-up plus campaigns at or below 50/day per mailbox
Issue: I have multiple campaigns but only one is sending
Fix:
This is expected behavior—global limits apply across all campaigns without prioritization
To control which campaign sends first, pause less urgent campaigns temporarily
Or use separate sending addresses for different campaigns
Issue: I set a limit of 30 but want to send more
Fix:
Add additional sending email addresses to your account, each with its own warm-up
Every new mailbox goes through the full ramp-up and 14-day stabilization before it sends anything cold
Issue: lemwarm emails are counted in my limit
Fix:
lemwarm emails should not count toward your global limit
If they appear to be counting, contact lemlist support—this may be a bug
Verify you're looking at campaign sending limits, not total emails sent (which includes lemwarm for informational purposes)
Optimization Tips
Start conservative: Start a mailbox at 10–15 emails/day in lemlist, add 5 per week, and cap at 25–30/day. Between two numbers inside the range, take the lower one.
Monitor deliverability: Keep one reputation signal running at all times — inbox placement tests 1–2 per month, or lemwarm at 10/day as the fallback. Never neither. If placement drops, lower your sending limit.
Use multiple addresses strategically: If you need higher volume, add more sending addresses rather than increasing limits beyond best practices.
Stagger campaign schedules: If running multiple campaigns from one address, stagger their sending schedules to avoid hitting limits.
Coordinate with lemwarm: Keep lemwarm running at 10/day once campaigns are live. Those 10 emails are not warming anything any more — they report reputation.
Review limits quarterly: As your sender reputation improves (or if you add/remove campaigns), adjust limits accordingly.
Never quote a volume without naming the phase: a ramp-up number and an active-sending number describe the same mailbox at different points in its life. Give the total before the split.
Export daily send reports: Use Reports to track how close you are to limits each day. Adjust schedules proactively to avoid hitting caps.
