How to Send Your Campaign in Batches to Warm Up Your Domain
Last updated December 17, 2024
Email domain warmup signals your service provider that you are not a robot or scammer. Preparing a high-volume campaign from a new account is crucial.
With Mailmodo’s Fragmented Scheduling feature, you can schedule bulk email campaigns in increments over seven days. Fragmented Scheduling is particularly useful for warmup campaigns, where gradually increasing your sending volume helps establish trust with mailbox providers and ensures better deliverability.
In 2019, Google took more stringent steps from email sending and receiving sides to detect spam emails. The email service provider gives daily sending limits when a user opens a new email account. However, a new account can’t use it entirely. Ideally, it takes 8-12 weeks to accomplish maximum deliverability.
Here’s our definitive guide to Domain Warmup to help you get started with understanding the warmup process.
Fragmented Scheduling requires you to configure the schedule only once, after which an automated flow manages the distribution as per your configuration. This method supports email deliverability best practices while helping you scale efficiently.

Setting Up a Fragmented Campaign (Step-by-Step)
Step 1: Create Your Campaign
- Navigate to Campaigns in Mailmodo
- Create a bulk campaign as usual
- In this select template -> add details -> select contacts -> review and send
- In review and send instead of selecting now select schedule options
Step 2: Enable Fragmented Scheduling
- Choose the option: ‘Send in batches at regular intervals (up to 7 days)’
- Configure the first batch. You can choose to send it Now or Later
Step 3: Select Days and Time Duration
- Define the specific days of the week and time windows during which your campaign should be sent
- If you select the Later option, choose the start date and time for the campaign
- Fill in the initial volume of users to be sent emails in the first batch
- Specify the time interval between consecutive batches (e.g., every 12 hours, daily)
Note: The ending time should always be after the starting time within a 24-hour window
Step 4: Set Initial Batch Volume and Intervals
Step 5: Configure Volume Increments
- Use the increment factor to grow your batch sizes over time. If you set the factor to 1.2x, the volumes will increase as follows: Batch 1: 100 → Batch 2: 120 → Batch 3: 144 → and so on
Step 6: Pause Between Campaigns (Optional)
- Add pauses during specific timeframe (e.g., overnight or weekends) to ensure no emails are sent during the designated period
- After configuring the schedule, click on ‘Preview Campaign’
- Review the overview of your schedule, including batch sizes, send intervals, and total duration
- If satisfied, enable the campaign
Step 7: Preview and Enable Campaign
Note: You can always return to edit the campaign schedule if needed
Best Practices for Warm-Up Campaigns
- Start Small: Begin with low volumes (e.g., 500-1000 recipients per day) and scale up gradually
- Focus on Engaged Segments: Send to your most active and engaged subscribers initially to build domain reputation faster
- Avoid Risky Lists: Do not include unengaged or inactive users during the warm-up phase, as this can harm deliverability
- Monitor Metrics: Track key performance indicators (added below) and make adjustments to your sending schedule based on these metrics.
- Open rates
- Click rates
- Bounce rates
- Spam complaints
- Stay Consistent: Maintain a regular sending cadence after warming up to avoid losing reputation with mailbox providers
