That’s you (and the large part of HN who doesn’t know anything about normal users). When GDPR came into effect, we even had people write us that they were annoyed having to reconfirm, as obviously they still wanted our newsletter.

Some people want to receive marketing emails. The exact same emails are spam to the rest of us. If you default opt-in users and don't make blanket unsubscription from all marketing emails easy (and make the clear distinction [both internally and externally] between emails regarding the existing functionality of products/services that we've already paid for and emails to ask for more revenue from us, which includes co…

Yup, nobody wants those emails. Unfortunately sales people and marketers are excellent liars and they convince higher ups that it's worthwhile.

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 One that comes to mind would be validating that a mailing list doesn't have any outdated email addresses in it, but couldn't that be determined by just checking for a bounce when a message is sent to it?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…

I maintain a small fee tool for creating API endpoints to trigger email alerts for yourself (varmail.me). Since it's very basic and has no marketing, it doesn't get too many users. You have to click a link in an email to even log in, but I still get bots stuffing my login form with known bad email addresses (I've googled and some of them appear in honeypot lists). There is no chance they can get in, but this is bad b…

Interesting project, maybe you need a captcha to display and weed out bots before you actually send an email.

I think what this is telling you is that users don’t value giving you their email address for your free tools. They know why you want their email address, and they don’t want that, but they do want your tools. Maybe it’s time to charge money for those tools or change models? Maybe not give access until the email address is confirmed? Worth considering I guess. Idk the details. I do this all the time. Ads and malpract…

Is it that risky? Talking, at least, as a somewhat knowledgeable person, which is the target of such web tools. I usually have no problem using my email address to sign up for things. And yes, I do know that emails will come. Sometimes they are actually useful and I keep them. Often, I don't care and I just unsubscribe. I some not-so-common cases, it is spam, in which case I mark it as such and I am never bothered by…

Issues I've had is after x years or some leak a ton of mail start pouring in.

Incorrect, I tried sending a mail and it bounced.

It is a valid email if the owner of the me tld sets up an email address on it. I'm not sure if anyone has done it on a tld but I have seen websites which are on the tld with no sub domain.

> I have seen websites which are on the tld with no sub domain.

Do you have any example of that?

Any kind of technical email validation is horribly unreliable at best and there is no chance that this GitHub repo is going to work any better.

As a result the only place such a service is useful is for someone who has a ton of low-value emails they don’t trust, and they don’t want a ton of bounces when they hit send (which risks losing your send privileges with pretty much high-volume email platform).

So they run all their emails through a service like this, and only send to the ones marked valid. This excludes a ton of emails that actually are valid, but failed the check (false negatives). But that’s ok because the emails were low-value to begin with.

If this sounds like a spammy operation… bingo. Technical email validation services are really only useful for people who are doing things like buying email lists from commercial providers, harvesting emails from sites like HN, or forcing people to enter an email address to do basic things with a free service.

I think they copied the licenses paging from a carousel library Flickity, they haven't replaced the company name from Flickity to reacherhq. [0]: https://help.reacher.email/reacher-licenses#31b18f7872fc4480... [1]: https://flickity.metafizzy.co/

Fixed, thanks!

It should only be possible on ccTLDs, this is not possible on newer gTLDs due to ICANN rules and I think no classic gTLD has it.

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…

But that would affect all customers of Amazon SES because the IP addresses would score low by other email servers.

Assuming that the customer's servers were hosted by some SaaS like Office, right?

If customer was hosting e-mail servers themselves they wouldn't notify any other mail servers?

It makes me uneasy that the SaaS Website has no Imprint even while it writes "Made in a small independent studio in Berlin 🇩🇪." In Germany an Imprint for a paid service is mandatory and after the ToS it seems like this is a product from a company in France? (I believe there are similar laws in France?)

What's an imprint?

https://en.wikipedia.org/wiki/Impressum

> The Telemediengesetz (German meaning "Telemedia Act") requires that German websites disclose information about the publisher, including their name and address, telephone number or e-mail address, trade registry number, VAT number, and other information depending on the type of company.

The relevant German laws (§5 TMG and §55 RStV) are fairly vague, so lawyers recommend publishing an Impressum if your website contains any commercial content (for example, ad banners) or any journalistic content (for example, blog posts).

Author here. Yes the company is in France, and I'm currently writing those (called "CGV" and "Mention légales").
