How It Works
This warmup system uses a
fixed-stage model
:* Each stage has a
daily sending limit
* You’ll progress to the next stage
only after reaching the current day’s limit
* No hourly caps are enforced
* Emails
must be sent through the warming domain
to move forward* Warmup
automatically pauses
once the daily limit is hit, and resumes the next dayNote:
During this initial phase, sending above the stage limit is allowed and emails will not be blocked. However, future updates will strictly enforce these limits and block excess sends once the cap is reached.---
How to Enable Warmup
For Newly Created Domains:
Warmup is enabled automatically after domain creation and verification.
For Existing Domains:
You can enable warmup manually from the following locations:
Agencies:
Settings → Email Services → SMTP Service → Dedicated Domain and IP
Sub-Accounts:
Sub-Account Settings → Email Services → SMTP Service → Dedicated Domain and IP
When enabling warmup on existing domains, the system will recommend a starting stage based on historical email activity and available Google Postmaster data.
