List Hygiene

Understand and maintain a healthy email list

Plunk automatically monitors the bounce and complaint rates of your emails to help maintain a health sender reputation. High bounce or complaint rates can negatively impact your deliverability and may lead to your account being suspended.

Bounce Management

A bounce occurs when an email cannot be delivered to the recipient's inbox. When an email bounces, Plunk will automatically unsubscribe the contact and also send an event on the contact for email.bounced.

Types of Bounces

Preventing bounces

Complaint Management

A complaint occurs when a recipient marks your email as spam. When a complaint is received, Plunk will automatically unsubscribe the contact and send an event on the contact for email.complaint.

Preventing complaints

  • Ensure your emails are relevant and valuable to your audience
  • Include a clear unsubscribe link in every email
  • Monitor your email frequency to avoid overwhelming your contacts
