I guess if they're big enough they should be working on moving off of amazon SES for emails and warming up ip addresses? Otherwise they need to keep a markup on top of amazon. Edit: didn't realize people were paying resend $20. AWS already exists at a low price and people pick them anyway, i'm sure they're fine.

I'm betting a non-small chunk of these are users AWS wouldn't let out of sandbox mode.

and you’d be 100% right!

AFAIK there is no communication service or protocol on the internet designed with idempotency in mind. (That was worthwhile and adopted)

Sure, but this is not a protocol, this is an API. APIs that allow actions that cost money, potentially annoy users / effect your reputation in the eyes of email recipients, I believe, should allow the caller to supply a unique key to enforce idempotency.

Track state on your side.

How much do existing services trust new email service providers? It would seem to be an uphill battle for Cloudflare to start a new service. It's easy to automate from the start, meaning it's easier to send spam. I suppose reputation is not simply based on the domain the email comes from?

Hi, I work on this team at Cloudflare. We've been sending email for years via our free email routing product and email sending is built on top of the same infrastructure, code and knowledge.

The problem is how bullshit transactional emails are when you're outside of AWS. If you're not expecting to use 10,000 emails a month but would like the option to go over the free tier without committing to 10,000 more. Just let me pay per use FFS.

The reason AWS does that is because there is a lot of base level work to verify you as "not a spammer" and to keep verifying you. So this is their way of making sure you pay the base cost. They could price per use, but it would have to start with a base fee that is about the same at 10,000 emails.

The base fee doesn't need to be monthly, they can take $50 dollars as a one time registration verification fee. That should be enough to cover their compute costs for the year, specially when you pool in that from multiple customers. Who is spamming with 100 monthly emails? How much compute do they need to verify you aren't spamming. They can bake all of that into the pay per use price, they choose not to and I'm glad cloudflare is offering this.

I'm not sure why this announcement has generated so much irritation in the comments-- Cloudflare has been transitioning from "DDoS protection" to "AWS competitor" for many years now, and this is just their alternative to AWS SES. It's an email sender that you can access through an API, or directly through Workers. For those who haven't been keeping up over the years, Workers is their product for running code on Cloud…

I've used their email relay services to forward it to my Microsoft account, every forward is rejected by Microsoft due to spam generated by Cloudflare. So I don't have much faith at least in their email services.

Of all email services, delivery to MS hosted systems is absolutely the worst to deal with. It's completely opaque and almost impossible to resolve most of the time. They tend to direct you to paid channels to try to mitigate issues instead of actually responding to complaints for false positive flagging as spam.

For my small, personal email server, I just gave up on trying... I can deliver to Gmail and every other major email provider without issue, and even MS seems to be split into a couple different backing orgs.

Blog author chiming in: Our initial blog covered most of Email Service's API and what you can expect from it in terms of deliverability, DNS records setup, etc. https://blog.cloudflare.com/email-service/ Email Service can definitely be used as a transactional email API, and it has everything you would expect like SDKs, binding, observability and more coming on the way The agent angle in this post reflects what we're…

>The agent angle in this post reflects what we're actually seeing from developers during our private beta. legit question: did you invite anyone that isn't doing agentic whatever during your beta?

It's most likely people doing active development, willing to experiment on a test/beta platform... which probably correlates strongly with those testing/trying agent based workflows.

Oof. I know of a startup that recently Show HN'd here, the agent mail.to, that is NOT having a good time right now. I don't know what all these new startups having moats thinner than Durex are thinking -- like, what the plan if someone does what you do, faster and cheaper?

“Each agent gets its own identity from a single domain.“ That too on the edge, along with the futuristic CF Dev primitives.

I had the same thought when I read this part. The $6MM investment on Agent Mail is in serious trouble right now.

My experience has been the opposite of what you're saying: AWS SES (one of AWS's flagship products, and probably the biggest email sender in the world) is a pretty responsible anti-spam citizen. Spamhaus even wrote this article[1] praising SES's anti-spam efforts. From the article: "Amazon SES has a long-standing relationship with Spamhaus, working closely to prevent suspicious IPs and domains from impacting their ne…

Whatever IP people temporarily host on a cloud incurs the prior users reputation. Again, using legitimate traffic to shim network spam is a common counterargument against black listing. Of the approximate 274000 banned hosts I stare at... many nuisances are from Amazon, Azure, digital ocean, and Hetzner. I am sure Maildrill or Mailchimp does have legitimate use cases, but generally the majority of the traffic suggest…

Are those hosts using hosted VPS instances, or are they sending through SES? There's a pretty significant difference... FWIW, I get why a lot of VPSes simply block email hosting altogether. It makes it a bit harder for me to find a host for my own small server, but I do understand the pain. Some services are better or worse, and I can imagine at the scale of many cloud hosts, trying to keep the IPs for general hosting out of blocklists would impact the bottom line more than reputational damage for a handful of legit email hosting accounts.

TBF, the demo app referenced in TFA and depending on how many emails you actually send for however many domains may well be a better option for me than my small MTA server.

No mention in the announcement that it is restricted to the paid plans. Also no mentioned of it in the paid plan comparison.

From the dashboard link:

> Enable Email Sending Email Sending is currently only available with the Workers Paid plan. Upgrade your plan to start sending emails.

> Everyone already has an email address, which means everyone can already interact with your application or agent. And your agent can interact with anyone. That’s a huge assumption unless you exclude several countries where people have a phone number but not really an email address (or even if they do, they may not know what an email address is) and exclude many very old (say, 70+) people who wouldn’t know what email…

It is a new customer email service/platform... analogous to AWS SES for being able to send emails. They also have a baseline web email application.

That said, would be nice if CF offered an analog to gmail/m365 email, contacts and calendars as a service to go along side the application access. As it is, I'd probably use a subdomain for service based emails, separate from user emails if using this service.
