How to Configure Warmup in Reachkit

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

  1. Navigate to the Inboxes section in the left sidebar
  2. The Warming column shows whether each connected inbox is warming
  3. Open the inbox to see the live ramp-up, daily activity, and health score

Configuring Your Warmup Settings

To access and modify warmup settings:

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

Available Warmup Settings

Setting Default Description
Warmup emails per day 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:

  1. Select your inbox from the Inboxes section
  2. The Overview tab shows your warmup performance
  3. Key metrics include:
    • Health Score: How much of this inbox’s warmup reached the inbox over the last 7 days, out of 100. Every warmup email is checked at the receiving mailbox, and one found in a spam or junk folder (Gmail’s Spam, Microsoft’s Junk Email, or any other provider’s) lowers the score. Inboxes usually score lower at Microsoft, which filters more on content and sender history.
    • Weekly Emails: Warmup emails sent in the last week
    • Landed Spam: Warmup emails that landed in spam or junk and were moved back to the inbox
    • 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.
