Common Mistakes to Avoid During Email Warm-Up

While email warm-up is essential, it’s crucial to avoid common mistakes that can hinder your progress and negatively impact your sender reputation. By steering clear of these pitfalls, you can ensure a smooth warm-up process and maximize your chances of inbox success.

1. Rapidly Increasing Email Volume

One common mistake is rapidly increasing the volume of emails sent during the warm-up process. This aggressive approach can trigger spam filters and cause deliverability issues. Instead, take a gradual and measured approach to increase your sending volume over time.

2. Neglecting Engagement Metrics

Engagement metrics, such as open rates, click-through rates, and replies, play a vital role in email warm-up. Neglecting to focus on these metrics can harm your sender reputation and result in lower inbox placement rates. Make engagement a priority and encourage recipients to interact with your emails.

3. Ignoring Feedback Loops and Complaints

Feedback loops provided by ESPs allow you to monitor recipient complaints and unsubscribe requests. Ignoring these valuable insights can lead to continued sending to uninterested or disengaged recipients, harming your sender reputation. Pay attention to feedback loops and promptly address complaints to maintain a positive sending reputation.
