Quote Transactional Email for a SaaS Client

Walk an agency quote: 10,000 transactional emails per month across SES, SendGrid, Resend, and Postmark — plan floors on the PDF, not a fake per-1k line.

Steps

  1. Open the Email Cost Calculator.
  2. Set emails per month to 10000 (or the client’s number). If they said “10k emails” and might use SES, confirm they mean recipients.
  3. Leave SES free allowance on None unless they showed you an AWS allowance.
  4. Leave Cloudflare Already on Workers Paid according to whether they already have Paid (uncheck if Email Sending would be the upgrade).
  5. Read the table. In the 2026-08-18 card at 10k you should see SES $1.00, Postmark Basic $15, SendGrid Essentials $19.95, Resend Pro $20.
  6. Put SKU names on the quote (Essentials 50k, Pro 50k, Basic), not “about $0.20 per 1k.”
  7. Optional: open vendor presets — SendGrid, Postmark, SES — if the client asked for a brand-named PDF screenshot.
  8. Add a one-line disclaimer: dated estimate, not an invoice; taxes and dedicated IPs omitted.

Watch out

Frequently Asked Questions

Should I ×12 for an annual quote?

You can, but say it is 12× the monthly SKU with no annual discount modeled. Vendors often sell yearly cheaper — Tools.Town v1 does not.

What volume should I put in the tool?

The client’s expected *recipients* if SES is in the mix; otherwise their send count. Ask which they meant. Wrong unit is the usual quote bug.
