How do I recover domain reputation after a sudden high volume email send to unengaged users?

Summary

Recovering domain reputation after a sudden high-volume email send to unengaged users involves several crucial steps. Initially, halt sending to the problematic list. The reputation drop stems from increased volume, potential complaints, and sending to invalid addresses. Implement a gradual warm-up, increasing volume incrementally, and avoid drastic volume shifts. Segment your email list based on engagement, focusing on re-engaging active subscribers and cautiously reintroducing unengaged users. Maintain consistent sending volume over time. Regularly clean your email list by removing inactive subscribers. Ensure email authentication with SPF, DKIM, and DMARC. Employ feedback loops and monitor your performance using Postmaster Tools. Sudden changes are not liked by spam filters. Sender reputation, domain age and email volume affect your sender score. Finally, consider the content and identify and deal with complaint problems.

What the experts say

8 expert opinions

Recovering from a domain reputation drop after a sudden high-volume email send to unengaged users requires a multi-faceted approach. Primarily, stop sending to the problematic list immediately. The drop is likely due to the volume spike and potential mailing of non-existent addresses. Gradual warm-up is crucial - avoid significant volume shifts overnight. Consider trickling out mail over time, increasing volume by no more than 10% daily during warm-up. IP warming might be necessary if it's a new IP or hasn't been regularly used. Remember spam filters are sensitive to sudden changes. Domain age, sender reputation and email volume affect your sender score, segment the audience, re-engage subscribers, and don't wildly increase the volume.

Key opinions

  • Stop Sending: Immediately cease sending to the problematic list to prevent further damage.
  • Gradual Warm-up: Warm up the domain gradually, avoiding drastic volume increases.
  • Segment & Re-engage: Segment your audience and attempt to re-engage subscribers before large sends.
  • Volume Sensitivity: Spam filters are sensitive to sudden changes in email volume.
  • Reputation Factors: Sender reputation, domain age, and email volume affect your sender score.

Key considerations

  • Mailing List: Carefully identify and suppress unengaged subscribers or those who don't exist.
  • Daily Volume Cap: Monitor daily email volume and avoid multi-order of magnitude increases.
  • IP Warming: Determine if IP warming is necessary based on IP history.
  • Content Quality: Check the content for possible problems, or reputation issues.
  • Complaint Monitoring: Complaint levels from users have a significant negative effect.

Expert view

Expert from Word to the Wise, Laura Atkins, shares that sender reputation, domain age, and email volume all play into your overall sender score and deliverability. A sudden increase to email volume without a strong sender reputation will result in a lower score. If possible, you should segment your audience, and attempt to re-engage subscribers before sending to the entire list.
