Summary
The prevailing consensus across email marketing experts and documentation is that an email sender's reputation can indeed be permanently damaged by repeated cycles of massive sends and pauses, alongside other detrimental practices. Factors such as inconsistent sending patterns, neglecting list hygiene, sending unsolicited emails, ignoring recipient engagement, and generating spam complaints all contribute to a decline in sender reputation. As reputation diminishes, recovery becomes increasingly difficult, costly, and may ultimately lead to blacklisting. Maintaining consistent sending habits, practicing diligent list hygiene, avoiding spam-like behaviors, and actively monitoring sender reputation are crucial for preserving long-term email deliverability.

What the experts say
5 expert opinions
Experts agree that an email sender's reputation is crucial and sensitive to sending habits. While reputation repair is possible if acting in good faith, repeatedly engaging in practices like irregular sending cadences, neglecting list hygiene, and prioritizing short-term gains over long-term health can lead to significant, potentially permanent damage. Human intervention in reputation management can make recovery more difficult, and recipient mail services are less likely to forgive a low reputation sender. Documenting risks and managing client expectations are also crucial to protect deliverability.
Key opinions
- Reputation Repair: Repair possible with good faith efforts, but bad actions cause long-term harm.
- Irregular Sends: Inconsistent sending habits and neglected list hygiene damage reputation.
- Short-Term Focus: Prioritizing short-term gains over long-term health harms deliverability.
- Human Intervention: Recovering from human intervention in reputation is harder than machine learning.
- Document Risks: Documenting risks and managing expectations is important for protecting deliverability.
- Critical and Ongoing: Sender reputation is a critical and ongoing element in email.
Key considerations
- Good Faith: Operate in good faith to increase the chances of reputation recovery.
- Consistent Sending: Maintain a regular sending cadence and avoid large, irregular sends.
- List Hygiene: Regularly clean and maintain your email lists to ensure high engagement.
- Long-Term Strategy: Prioritize long-term reputation health over short-term gains.

- Continual Monitoring: Constantly monitor your email reputation.
