What caused your sender reputation suspension

Sender reputation suspensions often arise from email practices that negatively impact the recipient experience, such as:

These elements collectively shape your sender reputation data and trigger a suspension when they consistently fall below acceptable thresholds.

3 Steps to fix your sender reputation

Fixing your sender reputation suspension involves three main steps.

1. Diagnose the immediate cause

Review your most recent email campaign report and carefully examine the data for specific indicators of your reputation challenge. Find the campaign that coincided with the issue and see if the bounce rate increased sharply following a particular send. Did you use a new list segment or one that had been inactive for a significant period? Investigate the exact origin and collection methods of that specific list. This focused review helps you pinpoint the immediate trigger for the suspension.

2. Take corrective action

If high bounce rates caused the issue, quickly remove the problematic list segment from campaigns. If an old list is the cause, stop sending to that group and create a plan to either re-engage its subscribers with consent verification or thoroughly clean it.

Then, contact your email service provider’s support team and explain the steps you have taken. Request that they review your account status and lift the sender reputation suspension. Your service provider can help validate your configuration, but if it is not the reason for your suspension, it won’t help much.

3. Test before sending again

Proactive testing can help prevent similar incidents. Deliverability in Litmus scans your outgoing emails against major spam filters and common blocklists before sending. Identify potential delivery obstacles and make adjustments so that your campaigns reach the inbox and keep your improved sender standing.

Don’t just fix it, prevent it

Focus on your email list hygiene. Remove invalid and unengaged addresses from your database to reduce bounce rates and avoid spam traps. Before adding recipients to lists, obtain explicit consent to email them. This way, you build a foundation of trust and compliance. Also, remember to make the unsubscribe process clear and straightforward to reduce recipient frustration and prevent unnecessary spam complaints. 

Then, monitor how recipients interact with your emails. If engagement isn’t high, adapt your content and mailing frequency to complement subscriber interests. Use email authentication protocols such as Domain-based Message Authentication, Reporting, and Conformance (DMARC), Sender Policy Framework (SPF), and DomainKeys Identified Mail (DKIM) to reinforce your legitimacy as a sender.
