More spam at scale. I wish recipients of email had more control over the conditions to which the email is delivered to them, rather than after the fact curation…

Along these lines, I am experimenting with a two-tiered system where I use Proton's sieve filters to create a sender/cc/bcc whitelist for personal emails (which alert my phone) and a non-Proton collection of burnable aliases for everything else (which do not alert my phone). It doesn't solve the problem completely, but it is mitigating it pretty well so far.

After ticking every documented box to get out of AWS SES sandbox mode and being told nope and we can't tell you why, I'm all for this.

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.

Things developers believe about email

Or the even worse category. People sharing email.

There is not much developers UNDERSTAND about email, let alone believe... There's soo much to read into this product.. and it boils down to JASS ( just another spam source) .

I’ll have to take a look at this as a way to move off my homegrown serverless email on AWS. Doesn’t look like it has parity with being able to send email from many subsystems safely (with delay and veto)[1], but is pretty close on the receive side automation[2].

I've been very happy with agentmail.to for a while with great success. You get 3K free emails per month with 3 inboxes. Paid tier starts at $0.20 per 1000 emails.

Disclaimer: I don't work for agentmail.

Ok I just tried the service since I want to migrate from Resend.

Seems like you can only send email via the worker or REST API for now?

Can I send via SMTP? I'm using Supabase and it needs the SMTP credentials.

I can't find anything on the dashboard or on the docs, even though last year they said it supports SMTP [0]

Not to oversimplify the issue... but you could probably run a small VPS and SMTP relay service that requires tls+auth and just relays all email from your domain through to API calls. You could probably get something operational in a couple hours with Claude Code.

My first thought in reading this would be using this service and the default mail app's structure to back end typical email protocols so you can still use a regular email client to access/use the system as a gateway.

That said, I still think Cloudflare is in a unique position to compete with gmail/m365 mail/calandar/contacts... possibly funding Thunderbird development to tighten the integration as a mail client.

For that matter, I still think cloudflare is in a good position to create a new

Oh yeah for sure. At that point, using SES is probably a better option compared to running a VPS just for SMTP. I posted that to let them know that SMTP support is a requirement for some developers.

Yeah one of their devs (https://news.ycombinator.com/threads?id=thomgo) said SMTP will be available, but I cannot find any info on this either. I'm glad to be switching from the horror that is Sendgrid, though. I migrated a few projects that have basic contact forms and it's been super easy so far.

> 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 is or what their email address is.

Moving on, I assumed the title meant the launch of a new consumer email service or platform. Reading the announcement, it’s not. That was disappointing to me.

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.

Cloudflare is very transparent about their prefixes and reverse DNS, which is generally a good thing for the ecosystem! But it makes it trivial for operators who want to block the entire service, and extremely bad for Cloudflare's deliverability.

And while there are many open blacklists which I have no doubt Cloudflare monitors, there are many (including soft spam-classification signals) that are proprietary and difficult/impossible to monitor other than by watching rates of actual customer/prospect replies and engagement.

Amazon SQS has similar dynamics, and its reputation is far from stellar.

(If the Cloudflare team is reading this, and I'm missing an on-ramp to a company purchasing dedicated IPs with distinct PTR records, I do apologize! I'm not seeing documentation about this, though.)

I think this is going to be a really good service: the service can be used easily with Workers making it super easy to not only send transactional emails but use it for forms embedded in Pages. I am very much looking forward to using this.

However, I still think AWS SES is the gold standard of deliverability because of their constant monitoring of your reputation (bounces etc). I always combine it with SendOps (https://sendops.dev/) for easy setup and deep analytics to avoid those issues.
