Dedicated vs Shared IP Cost Calculator

Dedicated IPShared IPESP CostInfrastructure ROIEmail Cost

Compare total monthly cost between your current ESP and dedicated sending infrastructure.

Monthly Email Volume

Current ESP Cost per 1,000 Emails ($)

Dedicated Server Monthly Cost ($) VPS/dedicated server + MTA license

Number of Dedicated IPs Needed

IP Cost per Month ($) Per IP per month

The per-email cost is only part of the picture:

Deliverability tax: Shared IPs mean shared reputation — neighbor spam affects your inbox rates
Scaling penalties: ESP pricing often increases non-linearly above volume thresholds
Feature limits: Dedicated infrastructure allows custom PTR, DKIM rotation, and full MTA control
Data ownership: Shared platforms retain sending data; dedicated infrastructure keeps it private

Most senders above 300,000 emails/month find dedicated infrastructure more cost-effective once deliverability improvements are factored in.
