1. From the Email Accounts Page
Go to the Email Accounts section.
Find the warmup icon next to your email account.
If the icon is grey, warmup is off.
Click it once — it will turn blue, meaning warmup is now active.
2. From Account Settings
Click on the email account (or the three dots → Analytics & Settings).
Open the Warmup tab to view warmup analytics.
Switch to Settings to configure warmup options:
Filter Tag: Organize warmup emails into a specific folder in your inbox.
Daily Limit: Maximum number of warmup emails sent per day.
Ramp-Up: Gradually increase sending volume.
Advanced Settings: Fine-tune how warmup behaves.
Activate Warmup Email Ramp-Up to configure Ramp-Up:
Initial Daily Email Limits: The number of warmup emails your account will send on the first day of warmup.
Daily Increment In Emails: How many extra emails get added to the limit each day as the warmup ramps up.
Note: For newly connected email accounts, warmup starts automatically as soon as it’s enabled.
