Cloudflare Email Service
The most recommended of 6 email sending services
Cheap per-email pricing and tight integration with Cloudflare Workers and other tools people already use. Most common caveat: no SMTP interface yet, and agent-sent mail may hurt deliverability.

What people warn about
Each mark is one comment
Limited sending options, no SMTP
“Doesn't look like it has parity with being able to send email from many subsystems safely”
Comment from 16 Apr 2026 in “Cloudflare Email Service: now in public beta. Ready for your agents” “Seems like you can only send email via the worker or REST API for now?”
Comment from 16 Apr 2026 in “Cloudflare Email Service: now in public beta. Ready for your agents” “without SMTP support, the email sending service is mostly unusable”
Comment from 18 Apr 2026 in “Cloudflare Email Service: now in public beta. Ready for your agents” Hype and AI marketing criticized
“Of course it's just marketing, but that doesn't mean it's above criticism, especially when it's shoved so hard down our throats.”
Comment from 16 Apr 2026 in “Cloudflare Email Service: now in public beta. Ready for your agents” “All the examples they show in the blogpost are just things that were already pretty easy without agents.”
Comment from 16 Apr 2026 in “Cloudflare Email Service: now in public beta. Ready for your agents” “launch the same service that's been around for decades but slap ai and agent on it”

Agent mail risks spam and deliverability
“Agent-produced emails are by definition spam. Everyone should be reacting to this news by immediately blocking your service.”
Comment from 16 Apr 2026 in “Cloudflare Email Service: now in public beta. Ready for your agents” “Why would Cloudflare ruin their email deliverability by allowing this?”
Comment from 16 Apr 2026 in “Cloudflare Email Service: now in public beta. Ready for your agents” “If I get one email from your agent, I'm torching your entire domain.”
Comment from 16 Apr 2026 in “Cloudflare Email Service: now in public beta. Ready for your agents” Cloudflare abuse handling criticized
“Cloudflare is very transparent about their prefixes and reverse DNS, which makes it trivial for operators who want to block the entire service”
Comment from 16 Apr 2026 in “Cloudflare Email Service: now in public beta. Ready for your agents” “the state of affairs at Cloudflare's Connectivity Cloud looks less than optimal from an abuse-handling perspective”
Comment from 16 Apr 2026 in “Cloudflare Email Service: now in public beta. Ready for your agents” “Cloudflare is (in)famous for not acting against spammers, fraud, piracy and other less savory groups”
