Isn’t part of the reason for using Mailgun, Sendgrid etc that you get to send via IP addresses with good reputation?

Mailgun and Sendgrid send plenty of spam. It boggles the mind that they have a "good reputation" when nearly everything they send me is unsolicited.

We really need a better solution to fighting spam. https://github.com/jimktrains/email_ng is an overly complicated idea I had once, but the basic gist is that the receiver could give the sender a signed receiver email address that is for the sender's email address. This way, transactional email (and sure, I guess marketing from your company) would be able to get through and the email given out wouldn't be able to be…

yes, but as someone who's worked on the sending of emails side of this i can assure you that the techniques for fighting spam are TOO effective. There are many legit emails that go into black holes before any standard idea of spam filtering comes into play. I wrote an embeddable smtp server so that you could have an app that sent email without ever asking your users to put in their SMTP server info... it was USELESS because of SPF filtering. The blacklisting of whole IP ranges means that no app could use it on a home computer because all those IPs are banned.

we definitely need a better solution to fighting spam.

I assume you mean rarely receive spam that ends up in your inbox. Or does your email someone not receive any spam at all?

This sounds like a cryptographic way to achieve the aliasing scheme many people already use, e.g "chatmasta+hackernews@gmail.com". Your proposal requires at least the status quo (aliased email address at signup), but the problem is it also requires cooperation of the receiver's email provider (e.g. gmail) and the sender's email provider. You are unlikely to ever see any new standard adopted by all major email provide…

why not just add +sitename to your email when you sign up..... eg me@example.com becomes me+flickr@example.com ? it's just a comment that will be ignored. I don't feel that we need software support to help with that. Your password manager will store that address (since it's probably your username) and help you fill it in / remember it when you come back to the site.

It's the former. I use gmail and for me, they are almost perfect. It's been probably three or four years since my last false positive and less than 1% of the email I do see is spam that was missed.

For phone calls, somewhere between 30 and 50 percent of my calls are robocalls or other telemarketing (I receive far more emails than phone calls).

If there were an easy way to tell my phone to just drop callers if they aren't in my phone book, I would. Right now, my phone lets me know if a caller is a suspected spammer, but when I hit dismiss, it goes to voicemail. I'd rather have the call just dropped or for the caller to get a busy signal. That reminds me - I can't remember the last time I heard a busy signal.

This is a big reason for sure. As you can see in this post, those IP addresses can be hit or miss depending on the provider. At Postmark, we don't really believe in dedicated IPs for all customers. We think that our customer base should not include any bad actors, and instead manually approve every customer to ensure our entire CIDR ranges are clean. The benefit is not just clean IPs, but clean IPs that have an incre…

Why wouldn't spammers just start adopting Postal on their servers, too?

If I were to host this myself, I'd still need a static IP that had a good reputation. GCP and Azure both mention that we should not be hosting mail servers on their platforms (rather, they all suggest we setup mail servers + relays to a reputed IP). How would I go about getting a static IP or a reputed IP?

Companies have been renting/leasing servers for a long time before Amazon and Google got into that business.

We sent a lot of emails which makes services like Postmark or Mandrill very expensive. Since switching to Amazon SES, the cost has been much lower but the lack of individual email tracking has been a pain (in case a recipient claims they haven't received it or we need to track opens, etc). This UI with an Amazon SES backend would be ideal.

If you’re sending newsletters, you might want to look at Sendy[1] (no affiliation), which sends via SES. 1 https://sendy.co

There was a lot of activity in this space when Mandrill "died" last year.

Per "Create your own MailChimp clone for $5 a month with Sendy" | https://news.ycombinator.com/item?id=9151487

The Sendy codebase is horrifying. [...]Just lots and lots of rough PHP _vs_ This isn't software to be used for analysis. Sendy is f-in awesome!

Amazon SES rocks from a pricing standpoint but deliverability isn't its strong suit _vs_ I find no difference between SES and MailChimp regarding delivery

I would stick with Sendy, but I could never get the unsubscribe links to work _vs_ there is a version 2 of Sendy, which appears to fix all these problems

lighter version of Mailchimp and super cheap [...] Configuration is a bit painful

I have been using it for almost 1.5 years and really like it.

if you are taking all the trouble to install Sendy you should look at Mandrill (2 years go) _vs_ Major changes to Mandrill, must be tied to a MailChimp account (1 year ago) | https://news.ycombinator.com/item?id=11170713

My only phone number that people have is a Google Voice number and it's really funny when I have five five-second silent voicemails every day. Because none of them ever go through to my phone...
