How to use this calculator

Enter campaign cost, delivered emails, deliverability rate, and open rate. The calculator estimates CPM, cost per 1,000 opens, and delivery quality.

What the result means

Email CPM measures delivery cost, not revenue. A low CPM is useful only when deliverability, open rate, and conversion quality remain healthy.

Email CPM = Campaign Cost / Delivered Emails × 1000; Cost per 1,000 Opens = Campaign Cost / Opens × 1000

If deliverability is low, your apparent CPM may hide inbox placement problems and poor list quality.

Example calculation

If a campaign costs $500 and delivers 50,000 emails, CPM is $10. With a 30% open rate, cost per 1,000 opens is about $33.33.

Tips for better results

  • Clean inactive subscribers regularly.
  • Monitor bounce and spam complaint rates.
  • Improve sender reputation before increasing send volume.

FAQ

Divide campaign cost by delivered emails, then multiply by 1,000.

What is a good email CPM?

A good email CPM depends on list quality and revenue per recipient. Low cost is useful only when deliverability and engagement stay strong.

How can I reduce email delivery costs?

Improve list hygiene, remove inactive contacts, consolidate tools, and avoid paying for subscribers who never engage.

Does deliverability affect email CPM?
