Introduction to IP Warm-Up

Why Warm Up Your IP Address?

Warming up your IP address helps build trust with email providers and ISPs, demonstrating that your email traffic is legitimate and not associated with spam. This, in turn, improves your deliverability rates and ensures that your messages reach the inbox.                                                                                                                                             


Step 1: Verify Your Sender Identity

Before you start sending emails, it’s crucial to verify your sender identity with MSG91. This step ensures that your recipients recognize you as a legitimate sender


Step 2: Segment Your Audience

Divide your email list into smaller segments based on factors like engagement level, activity, or subscription source. This allows you to gradually increase sending volume to each segment.

Step 3: Gradual Volume Increase

Begin by sending a small volume of emails to the most engaged segment of your audience. Monitor the engagement metrics (open rates, click-through rates) to gauge the response.

Step 4: Monitor and Adjust

Keep a close eye on your email performance metrics. If the initial emails show positive results and there are no deliverability issues, gradually increase the volume to the next segment.

Step 5: Maintain Engagement

Continue sending relevant and engaging content to maintain a healthy sender reputation. Avoid sending to inactive or unengaged recipients during the warming-up process.

Step 6: Monitor Complaints and Bounces

Regularly check for any complaints or bounces. Address any issues promptly and take necessary actions to resolve them.

Step 7: Full-Scale Sending

Once you’ve successfully warmed up your IP address and achieved consistently positive results, you can gradually expand your sending to the entire email list.
