These are "scanner-proof" so far but support in clients like Outlook or Gmail is non-existent.
Which spammers and marketers would have loved.
I have "load remote content" disabled on my e-mail client so that tracking graphics/pixels do not leak such information to the sender.
Often times that's meaningless as email scanner software will load and inspect all links and images regardless of the human's email client preferences. It basically comes down to can Constant Contact, or similar, detect if a link was clicked by security software or an actual human. And security software wants to look like an actual human because if security software looks like security software it's very easy for bad actors to serve safe payloads to security software and malware payloads to human actors.
I find this hard to believe since everyone else seems to manage this without a Captcha.
Did you mean "and is NOT triggered by email scanners"?
AFAIU, "email scanners" get more aggressive over time, so there is no once-and-forever solution. I guess AI-enabled email scanners can attempt to solve captchas as well.
If the email scanner of your recipient insists on clicking "unsubscribe" on their behalf without that being the desired outcome, that's not on you to prevent them from.
Hope you're not ever sending email to EU residents!
Have you ever heard of `List-Unsubscribe`? It solves your problem without massively annoying people and breaking accessibility and/or the law.
useless is in the eye of the beholder.
The fact that you happen to work on a mailing list product does not change that reality.
If other people do and you are making me jump through hoops as a result to preserve your conversion rate, I'm reporting you to the relevant regulator.
> the unsubscribe mechanism is broken
Which one?
Are you saying some security solutions actually send a `List-Unsubscribe`/`List-Unsubscribe-Post` compliant HTTP POST with the correct payload, or do you think a URL in the email body is the gold standard of allowing people to unsubscribe?
Or are you just telling yourself that rationalization to avoid acknowledging that you're probably causing massive annoyance to many recipients?
I can believe someone, somewhere has insane security software that does stuff like that. But I don’t believe it’s common.
One person's feature is another's anti-feature. I'm glad it's dead.
