Fixed-Stage Email Warmup for Sending Domains

Domain Warmup involves gradually increasing your daily email volume to build a trusted sender reputation with inbox providers, such as Gmail, Outlook, and Yahoo. A well-executed warmup process can help avoid common issues such as emails being flagged as spam, high bounce rates, or delivery delays.

Key Features and Benefits

Improved Email Deliverability: By gradually increasing your email volume, you build a positive reputation with inbox providers, reducing the risk of your emails being flagged as spam or experiencing delays.
Automatic Process: For newly created domains, the warmup process is automatically enabled, allowing you to start sending emails without needing manual intervention.
Fixed-Stage Model: The warmup process uses a predefined, gradual stage model that allows you to progress through different sending limits as your domain earns trust with inbox providers.
Trackable Progress: The system tracks your progress and ensures you adhere to daily sending limits to avoid sudden spikes in activity that could raise red flags with inbox providers.

How Domain Warmup Works:

Gradual Email Volume Increase: Each stage of the warmup process has a predefined daily sending limit.

Stage Progression: Progression to the next stage only occurs when the full daily limit for the current stage is reached.

No Hourly Limits: There are no hourly limits, only daily limits for each stage.

Tracking Progress: The system tracks progress as long as emails are sent through the warming domain.

Sending Beyond Daily Limits: You can send emails beyond the daily limit, and additional sending will not be blocked.

Once the daily limit is reached, the system pauses further sending from the domain until 12:00 AM UTC of the following day. If the daily limit is reached, the next stage will begin automatically.

When Does Warmup Start?

For Newly Created Domains: Warmup is enabled automatically when a domain is created and verified. No manual actions are required.
For Existing Domains: Warmup must be manually enabled. The system will analyze past email activity and domain reputation data to recommend the best starting stage for optimal progression.

Steps to Start Warmup for an Existing Domain:

Go to Settings within the Business Hub.
Click on Email Services.
Navigate to the Dedicated Domain and IP tab.

Choose your domain and click “Start Warmup.”

Google Postmaster Integration (Recommended):

Integrating your domain with Google Postmaster Tools provides valuable data about your domain's deliverability, including:

Domain reputation (High, Medium, Low, Bad)
Spam complaint rates
Authentication status
Delivery and error metrics

If the Google Postmaster integration is not set up or there is no data available, the system will notify you and guide you through the setup process.

Best Practices for a Successful Warmup:

Consistently send emails every day.
Use verified, opt-in contact lists to ensure quality email delivery.
Avoid sudden increases in sending volume.
Stick to the daily sending limits to avoid enforcement blocks.
Do not change the sender domain mid-campaign.

When Is Warmup Complete?

Your domain completes the warmup process when it reaches Stage 15 (250,000 emails/day). You will see a "Warmup Complete" label in the domain dashboard, and full-scale email sending will be supported.

Pro Tips:

Be patient: Email warmup is a gradual process, so it’s important to allow enough time for the system to build your sender reputation.
Monitor performance: Regularly check the warmup progress and ensure your email volume increases as expected. If there are any issues, investigate and resolve them early on.

FAQ:

1. What happens if I exceed the daily sending limit during warmup?

Sending beyond the daily limit is allowed, and your emails will not be blocked. However, progression will only occur if the full daily limit is met for that stage.

2. How long does it take to complete the warmup process?

The warmup process typically takes two to three weeks to complete, depending on the stage you start from and the consistency of your email sending.

3. Can I use any email lists during warmup?

To ensure the success of the warmup, it's best to use verified, opt-in email lists that have engaged recipients.

4. What happens if I don't follow the warmup process correctly?

Skipping stages or sending too many emails too quickly can lead to email delivery issues, including being flagged as spam or facing delivery delays.
