Use Fragmented scheduling for Warm Up Campaigns

Last updated December 10, 2024

With this feature, you can schedule bulk email campaigns in increments over seven days. Fragmented scheduling is particularly useful for warm-up campaigns, where gradually increasing your sending volume helps establish trust with mailbox providers and ensures better deliverability.

Here’s our definitive guide to Domain Warm-up to help you get started with understanding the warm-up 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.

1. Why Use Fragmented Scheduling?

Improves Deliverability: Gradual sending helps establish sender reputation with mailbox providers, avoiding sudden spikes that might flag your domain.
Automates Warm-Up: After configuring, the system automatically adjusts sending volumes and schedules.
Flexible Scheduling: You can select specific days, time frames, and increments to control email distribution effectively.
Supports Engagement Tracking: Allows you to observe how recipients interact with emails over smaller batches, making adjustments as necessary.

2. Setting Up a Fragmented Campaign (Step-by-Step)

Follow these steps to configure a fragmented schedule for your bulk campaign:

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 Durations

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.

Note: The ending time should always be after the starting time within a 24-hour window.

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).

Step 4: Set Initial Batch Volume and Intervals

Step 5: Configure Volume Increments

Use the increment factor to grow your batch sizes over time.

For example, 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 timeframes (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.

3. 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 such as:

Open rates
Click rates
Bounce rates
Spam complaints

Make adjustments to your sending schedule based on these metrics.

Stay Consistent: Maintain a regular sending cadence after warming up to avoid losing reputation with mailbox providers.

By following these steps and best practices, Mailmodo’s Fragmented Scheduling feature can help you seamlessly warm up your domain, improve your email deliverability, and prepare for higher volume campaigns.
