I have no email workers in my account. Are these restricted somehow?

Figured it out. I have to skip the "Getting started" flow to enable the email routing dashboard which has email workers.

J

johtso•4/4/24, 1:33 PM

is there any more information on the limits/behavious of email workers?

J

johtso•4/4/24, 1:34 PM

what happens if my worker throws an exception while processing the email?

J

johtso•4/4/24, 1:34 PM

and what are the CPU limits?

J

johtso•4/4/24, 1:35 PM

oh nice, that's straightforward

J

so it's really just a normal worker with email events bound to it?

Looks like the email routing deliverability has been marked as fixed.

I have created a email worker that currently logs all incoming email to a notion DB so that it doesn't have to be delivered.

Curious what other peoples experiences are with this service. It is pretty critical to not miss email.

Doesn't seem from my end like you're using Cloudflare or #email-routing in any way. So the closest I would say going forward, would be to take such stuff in e.g. #off-topic.

Yes, as CNAMEs, exactly as you were showing them above.

Then from the former, you need to remove "v=DKIM1; " from the content though.

Thought I'd pop my head back in again to throw my raised hand amongst some others indicating the issue re: email routing starting again. Mine's forwarding to Outlook addresses, but I assume others will be affected too considering it's a spamhaus blocklist again. Seems to have started around 5hrs ago,

I know this is a free service, but it's a pretty big one for it not to work.

Hate to complain about a free service but I am relying on this for some important emails.

Email Forwarding/routing can be ok, but I would really recommend not relying on forwarding for anything critical. It's just not a smart idea, this isn't CF Email Routing specific but in general any forwarding service will have issues, and has had occasional issues for a while:
https://community.cloudflare.com/t/gmail-blocking-emails-routed-from-cloudflare/468070/2?u=chaika
https://community.cloudflare.com/t/email-routing-to-gmail-blocked-as-spam/422232
Get a proper email host like Fastmail or Google Workspace or ProtonMail if it's important at all. Those would even let you reply from your custom inbox.

C

Chaika•4/11/24, 8:36 PM

(or alternatively get a receiving inbox of which you have full and complete control over the inbound filters so you can whitelist all the forwarded mail)

Ben•4/11/24, 9:13 PM

I completely understand that email forwarding services can be temperamental, but at the time I had assumed this would be as reliable as Cloudflare's other services. These emails are not critically important, but as with all emails, I'd quite like to be able to read them.

I am just a little concerned that this is a repeating problem and there hasn't been a massive amount of communication towards a solution. I would imagine that everyone using this service, regardless of the importance of their emails, are using it to consistently forward emails. I completely understand that this isn't directly Cloudflare's fault here, but I'm just a bit confused as to if I should be staying with this product if it is struggling to fullfil its core objectives and is showing little sign of improvement.

Sorry if this came off as ungrateful. I appreciate the hard work that goes into creating this product

You're all good. At least for me personally, I have a few emails each day going to gmail and they've been fine, not sure why gmail is upset at your forwarding, but I'm just saying in general even if CF finds some workaround/communicates with the gmail team to get this fixed, it's very likely it will reoccur occasionally in some form with some providers. It's just the nature of forwarding to some place you don't have control over, you're breaking spf/forwarding potentially spam through your/their domain, etc.

Cloudflare does not offer email sending.

You cant use email routing and workspace at the same time. (At least not without a very complex setup)

J

Jignesh Thummar•4/21/24, 4:59 PM

or may be we can use any external paid sending service like mailchamp ?

R

rdm•4/21/24, 5:06 PM

If you are not wanting to pay for Google Workspace and wanted to use Email Routing.. You will need 1) a mailbox to use for the destintation route. And if you want SMTP/outbound to truly be signed by your domain for increased deliverability, you would need a paid service for that outbound leg.

J

Jignesh Thummar•4/21/24, 9:46 PM
