How to Use

  1. 1 Enter emails per month (this preset assumes you already pay for Workers Paid)
  2. 2 Uncheck Workers Paid if Email Sending would be the reason you upgrade
  3. 3 Use verified-destinations-only if you only send to addresses you verified
  4. 4 Compare Cloudflare to Resend and SES at the same volume

Features

  • Models 3,000 included emails / account / month and $0.35/1k overage
  • Workers Paid $5 floor — omitted when you already pay for it
  • Verified destination addresses = $0 and do not count
  • Inbound Routing is unlimited mail; Worker CPU is not in this total
  • Same ranked table as the compare engine

Why it Matters

Cloudflare’s Email pricing page does not include the Workers Paid floor, and inbound Routing is easy to mix up with outbound Sending. This preset makes both gotchas visible next to Resend’s $20 Pro floor.

Frequently Asked Questions

Is inbound Email Routing free?
Routing itself is unlimited as mail on Free and Paid. A Worker that handles the message still bills CPU/requests. That compute is not in this calculator.
Do verified destination addresses count?
No. Sends to verified destinations are free and do not use the 3,000 quota. Turn on the advanced toggle if that is your only traffic.
Do bounces count?
Hard bounces count toward the quota. API and suppression rejects do not, per Cloudflare’s pricing page.
Why does this preset check “already on Workers Paid”?
Most people landing here already run a Worker. If Email Sending is why you would upgrade from Free, uncheck the box so the $5 floor is included.
Is this an invoice?
No. Dated estimate. Confirm on Cloudflare’s Email Service and Workers pricing pages.
