Overview

Domain Warmup in __CompanyName involves gradually increasing daily email volume to build a trusted sender reputation with inbox providers like Gmail, Outlook, and Yahoo. A well-executed warmup helps reduce spam flags, bounces, and delivery delays.

Fixed Stage Email Warmup for Sending Domains

Key features and benefits

1. Improved email deliverability by building sender reputation over time.
2. Automatic warmup for new domains so sending can begin without manual setup.
3. Fixed-stage model with predefined daily sending limits per stage.
4. Trackable progression so sending increases steadily and avoids sudden spikes.

How fixed-stage warmup works

• Gradual volume increases: each stage has a predefined daily sending limit.

• Stage progression: the next stage starts only after the full daily limit for the current stage is reached.

• Daily limits only: there are no hourly limits.

• Tracking: progress is tracked as long as emails are sent through the warming domain.

• Sending beyond the daily limit: allowed, but it does not advance progression.

  

When the daily limit is reached, the system pauses additional sending from the domain until 12:00 AM UTC the following day. If the daily limit is reached, the next stage begins automatically.

When does warmup start?

• Newly created domains: warmup is enabled automatically when a domain is created and verified.
