Warm Up in Email Sending

When utilising email services to communicate with your audience, it's essential to follow the warm-up process diligently. Warm-up is a strategic method to gradually increase your email sending volume, ensuring a smooth and successful delivery to your recipients.


Why is Warm-Up Necessary?

Sending a large number of emails abruptly, without a proper warm-up, can trigger spam filters on recipient clients such as Gmail or Outlook. These email providers monitor the sending behavior of IP addresses and domains. If they detect a sudden and high volume of emails, they may categorize your emails as spam or may blacklist your domain, leading to potential delivery issues.


How to Conduct Warm-Up:

To optimize your email deliverability, we recommend starting with a conservative email volume and gradually increasing it over a specified period. Here's a suggested approach:


  1. Day 1: Send a small batch of 5,000 emails.

  2. Subsequent Days: Increase the daily email count by 10-20%, gradually reaching your desired volume (e.g., 100,000 emails per day).


Benefits of Warm-Up:

  1. Improved Deliverability: Gradual increases in email volume help establish a positive sending reputation of your domain and IP, reducing the likelihood of emails being marked as spam.

  2. Enhanced Engagement: ISPs (Internet Service Providers) are more likely to recognize your emails as legitimate, leading to improved open and click-through rates.

  3. Avoiding Spam Folders: Warm-up minimizes the risk of your emails ending up in the spam folder, ensuring they reach your audience's primary inbox.


Key Takeaway:


Taking the time to perform an effective warm-up is an investment in the success of your email delivery. By following this process, you maximize the chances of your emails being delivered to the intended recipients' inboxes.
