There are no plans.
Where Resend sells you plans, MailySend is MIT-licensed software that deploys into your Cloudflare account. We don't run a service, don't hold your keys and don't send you an invoice — you pay Cloudflare for what you use, at their list prices.
$0
MIT licensed. Every feature, no gates, no seat count, no “contact sales”.

Cloudflare Email Routing costs nothing — inbound, parsing and threading included.
Cloudflare Email Sending has been in public beta since April 2026: Workers Paid ($5/month minimum) is a prerequisite, 3,000 emails per account per month are included, and it's $0.35 per 1,000 after that. Verify on Cloudflare's pricing page before you budget — these are their numbers, not ours.
Drag to your volume.
Left column is what Cloudflare charges you to run MailySend. The rest are published list prices for the same volume elsewhere, for context.
100,000 emails/mo
Estimates for planning, not a quote. Storage, queues and analytics add cents at small volume and single-digit dollars at a million. Full worked examples →
All of it. There's no tier to upgrade to.
Nothing here is an add-on, a seat, or a sales conversation. If it's in the repo, it's yours.

Fair questions
The cheapest way to find out is to deploy it.
About a minute, one command, your account — most of it DNS propagation. Delete it with one more if you hate it.
