Can an email sender's reputation be permanently damaged by repeated cycles of massive sends and pauses?

What the experts say
5Expert 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.

  • 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.
