A non-marketing example: We were onboarding a large new client to our SAAS product. This process involved creating accounts for all of their employees (tens of thousands) and sending emails with an activation link. (Where they'd be able to set up their password.) Our system sends these emails in batches, and as soon as the first batch went out we got an alert from our monitoring system that our bounce rate was surgin…

I’ve never worked with emails, could you not send these first emails yourself and not use SES

Have you looked into what SES or other email services provide? Sending emails is easy, while actually getting them delivered is harder. You have to make sure you're not getting flagged as spam, can handle bouncebacks, etc.

Here's one discussion: https://stackoverflow.com/questions/371/how-do-you-make-sure...

Could someone spell out a use case for this? One that comes to mind would be validating that a mailing list doesn't have any outdated email addresses in it, but couldn't that be determined by just checking for a bounce when a message is sent to it? I tried to sign up for SiriusXM the other day, and though I could create an account with my .pro email address, I couldn't actually sign up for service with that same addr…

> Please hire me, SiriusXM.

Given their questionable business practices, their customer service dark patterns, their dated and awful UX, and their inevitable demise to much more popular streaming services, you’d be best to stay far away.

This is clearly trying to solve a non-technical problem with technical means. The root problem is that AWS cancels you with too high bounce rate. The obvious solution is to talk to some AWS representative to at least temporarily not cancel you after explaining the situation. If AWS does not let you talk to them, then that's where the problem lies, not in some not cleaned up email list.

It's terrible to spend a lot of effort on this kind of tech just because some business partner has shitty customer support.

I sometimes use it for sales. Looking up a company on LinkedIn, then finding the name of a person I want to each our to but am not sure about the email. Then I could try the classic first name.last name @ domain to see if it’s worth sending an email

My email address reachability is "unknown", its a fastmail hosted account. Quite a commonly used service. Is an unknown classification supposed to be treated as "I don't know, probably safe" or "I don't know, probably don't accept it" ?

  "smtp": {
    "error": {
      "type": "SmtpError",
      "message": "permanent: The host name specified in HELO does not match IP address."
    }
their server is misconfigured

Why did all the employees have email addresses from different services, rather than a single @ourcompany.com address pool that they controlled?

Used to be in the same camp, before starting my own company. While the border is thin, it is clear, and there is a difference between marketing and spam.

I think you proved the point: when the spammer send spam they think they are doing marketing.

I don't know about you, but I'm subscibed to several newsletters out of my own volition.. Are they spamming me then?

Interesting tool, but there are some really concerning dark antipatterns here that I really despise: Is the address provided by a known disposable email address provider? Is the email address bound to a known free email provider? Does email address under test hide a honeypot? What are the legit use-cases for this? To be sure you can force spam on your users and identify them as ad-targets?

If I ban a user who disrupts the functioning of the site, I don't want then to be able to immediately recreate an account. If there is more friction to this process, I can hope they will lose interest soon enough. Sure they can create an infinite number of Gmail addresses, but it might take then more time.
