I tried using Sendgrid and was surprised to find out that unless you buy an expensive plan, then: * You get IPs from a shared pool, and the reputation is nowhere near guaranteed. In fact, many of my mails were blackholed or rejected. * The "bad" IPs that were used by someone for spamming are not immediately removed from the pool, so you will encounter them. The net result for me was that Sendgrid is not a solution fo…

How can you check if an IP is good or spammy? It would be nice to get an elastic IP in the cloud, test it for spamminess, and give back the bad ones. Catch and release fishing for IPs.

You can check the Spamhaus lists. It's a non-profit org dedicated to all-things-spam. https://www.spamhaus.org/

I rarely receive email spam these days. The spam I get is on my voice line. I'm getting several robocalls per day. If you have the skills to work on this stuff, I'd love to see a solution to phone call spam because email spam feels solved.

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

I had exactly the same experience. For context I run a SaaS targetting small/medium businesses, who usually have in-house email servers with extremely restrictive spam filters. The IP was on a blacklist, so some of my customers just couldn't use my service. I contacted SendGrid and their only solution was to upgrade from a $20/mo plan to a $80/mo plan with a dedicated IP - they wouldn't even move me to another IP in the pool.

Given this, and my volumes of mail were increasing (once you go over 100k emails/mo SendGrid's pricing goes up a lot), I setup my own mail server using Cuttlefish [0]. I set it up on an OVH instance that I pay £2.50/mo for. I contacted them to enquire about spam policies before opening an account, and they said they take it very seriously and monitor outgoing SMTP for spam.

The IP address I ended up with was still on one blacklist, but the process to remove it was pretty easy (fill out a form, and explain the situation) and took about 1 day. I set this up around 6 months ago and have had no problems with deliverability since then, I'm now up to sending around 300k emails per month.

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…

Actually curious, so if I understand you correctly what you are saying is that a receiver had some software generated an address like johndoe+A16789HFF...@gmail.com and then sent it to the sender for use, that would require email providers cooperation. I am not clear on the "cooperation" parts work. I THINK its basically that email providers block emails based on other criteria like DNSBL. And the "cooperation" bit is to get the providers to manage these cryptographic email addresses like guard against their possible misuse?

My situation is the exact opposite. I almost never get robocalls but email spam is getting worse every month!

I think overall ISPs do a very good job at fighting spam. Compared to a decade and a half ago, I would call it a minimal problem. My greatest fear is that Google and Facebook will co-opt email and charge money for companies to get access. Google has already made some progress with this by selling ads in Gmail that look like email while pushing commercial messages in to other inboxes. This is bad because it penalizes…

Correction: large^W giant mail systems, that can observe a significant portion of world's mail, and have a lot of R&D resources, do a very good job at fighting spam (in their own systems).

A DIY home mailserver will still let, like, 5-15% of spam emails slip through.

Will this platform be actually usable for independent developers considering today's spam blocking scenario. How one should proceed with this in order to not get blacklisted while actually using it for the first time.

It's an interface, it doesn't take care of email reputation for you. This is for people who want to DIY to have a pretty dashboard on top, but you're on your own for email deliverability.
