Warmup is enabled automatically the moment you connect a new inbox, so there’s nothing to switch on. This guide covers how to verify it’s running, adjust the settings, and pause it if you need to.

Verifying Warmup Is Running

Navigate to the Inboxes section in the left sidebar
The Warming Status column will show “Warming” once an inbox is connected and verified
Open the inbox to see the live ramp-up, daily activity, and health score

Configuring Your Warmup Settings

To access and modify warmup settings:

While viewing your inbox, click the Settings tab
Scroll to the Warmup Settings section
Here you can adjust the following parameters:

Available Warmup Settings

Setting	Default	Description
Daily warmup limit	10	Maximum number of warmup emails sent per day
Increase per day	1	How many additional emails to add each day
Reply rate target %	30	Target percentage of warmup emails that receive replies

Understanding the Warmup Dashboard

To monitor your warmup progress:

Select your inbox from the Inboxes section
The Overview tab shows your warmup performance
Key metrics include:
- Health Score: Overall assessment of your inbox reputation
- Emails Sent: Total warmup emails sent
- Spam Rate: Percentage of emails that landed in spam
- Ramp-up Progress: Progress toward your daily sending limit

The Ramp-up Bar Explained

The ramp-up progress bar shows how far you’ve progressed toward your configured daily warmup limit. This is determined by:

Your daily increase setting
How long the inbox has been warming
Your maximum daily limit

Important Note: The ramp-up progress is not the same as overall warmup progress. It simply shows progress toward your daily sending limit goal.

Best Practices for Warmup Success

Be Patient: Allow at least 3 weeks of warmup before sending actual cold emails
Start Slow: The default settings work well for most users
Keep It Consistent: Don’t pause warmup during weekends or holidays
Monitor Health Score: A declining score may indicate adjustments are needed

When to Modify Default Settings

Consider adjusting your default settings if:

You’re warming up an older, established account (faster ramp-up possible)
You notice declining health scores (slower ramp-up recommended)

Remember that warmup is an ongoing process. Even after you begin sending campaigns, keeping warmup running helps maintain your sender reputation over time.
