List Hygiene Savings Calculator

Calculate the cost savings and deliverability improvements from removing dead weight from your list.

Typical: 15–30% for lists older than 12 months

What to Remove

  • Hard bounces: Remove immediately after first bounce
  • 12-month inactive: No opens or clicks in 12 months — suppress or run re-engagement
  • Role addresses: info@, admin@, postmaster@ — high complaint risk
  • Spam complaints: Remove immediately upon FBL notification
  • Invalid syntax: Email validation catches typeos at signup

For most senders with lists older than 18 months, removing inactive and invalid subscribers reduces costs by 15–35% while improving all key deliverability metrics.
