>If I think this approach is really effective, it also creates a huge pain for a lot of tools relying on emails such as WebEx invites or when you want to contact someone for sales.

I haven't used WebEx, but what is the problem exactly? Are you concerned you won't see the invite or that the sender will get an annoying automatic response?

Incidentally, this is all just a Python script. If you can construct a reasonable enough pattern for the email address, you can always have custom rules for them - it's fairly trivial. Just like I have a list where emails go straight to quarantine without producing an annoying email.

>or when you want to contact someone for sales.

My original design was to automatically whitelist anyone I send email to - in the end I didn't go that far, but it will likely alleviate this problem. My solution is mostly for my own personal email, though. If you plan to conduct a lot of business where you expect/want random people you don't know to email you, then this scheme won't work well.

>As a result I think that this approach might be better if it was for instance triggered only on emails with an “Unsubscribe” link, or on emails with specific keywords.

I just did a query. Fully one third of the quarantined emails do not have the word "unsubscribe".

Basically, WebEx sends invites from their own email address. If your customer has not white-listed the WebEx domain, they will not receive the WebEx invitation. The only solution we found for our sales team is to "double" the invitation with a manual email sent separately, with the link to the WebEx invitation...

Also, I just realized that I was not very clear in my comment: my company does NOT use MailInBlack :). However, a lot of our customers do, and this has been a nightmare for our WebEx invitations process.

That's rather obvious. If they want to receive emails from WebEx, they should whitelist it. Keep in mind that the quarantined emails are like emails in any folder. You can still check them to see if there are important emails there.

Now I don't know much about WebEx, but ... are you sending WebEx invites to people who are not expecting an invite? If so, I would say my filter is doing its job! That's exactly the type of email I'm trying to cut down on. If, OTOH, I am expecting an invite from you, I will check the quarantine folder for it. And as I said earlier, if WebEx becomes big enough that I expect many people will use it to contact me, I'll just whitelist and put it in the low priority folder.

Fundamentally, the problem is that we've overloaded emails. Emails (for most people) were a means of communicating between individuals. Then people started using it as a TODO list. Then as an advertising platform. Then as a way to manage receipts. Then as a calendar system. And on it goes. One of my goals is to separate the personal emails from everything else. I may still use it for other things, and set up scripts to handle those other things, but I need a way to separate out personal emails from everything else.

Now if WebEx also starts sending me unimportant emails, they're out of the whitelist. Kind of like LinkedIn. It uses [e-mail] for all its emails - whether it is to notify me that someone sent me a message or to let me know that "Hey, if you're willing to become a Premium member, everyone will want to hire you." - They are not in my whitelist.

And BTW, there is only one customer: Me :-)

Use the WebEx Productivity Tools extension for Outlook. Whenever I used WebEx with a client I supported, I would open up a new meeting in my calendar, type them a personal message, then click an "Add to WebEx" button and it'd automatically put all the necessary call information at the bottom of the invite. It'd be from the company email and I'd receive replies/notices of acceptance directly.
