What email marketers say11Marketer opinions
Marketer from Email Geeks says that list-unsubscribe is designated for the list in question. It is up to your IT/ESP to implement but recommend being really careful as you have no possibility to set expectations with the recipient who just might think he unsubed from all and could be rather unhappy with the next mail
Email marketer from Litmus shares that best practice is to always include a List-Unsubscribe header and provide clear options for users to manage their subscriptions. Directing users to a preference center gives you the most control.
Email marketer from Email Marketing Tips shares that from a customer experience perspective it is always better to give your users control to manage their preferences and subscriptions, rather than forcing a complete opt-out.
Email marketer from Mailjet shares that you can control the subscriptions a user is opted-out of by utilizing a preference center. When setting up List-Unsubscribe headers, link to your preference center rather than the one click unsubscribe option. They can then choose which email marketing preferences they wish to opt out of
Email marketer from Email on Acid says preference centers will allow users to select which emails they want to receive and which ones they don't. By providing that ability and honoring it, you can retain subscribers longer and increase engagement.

Email marketer from Reddit explains that while Gmail's one-click unsubscribe is convenient, you have control over the process if you implement it yourself. They suggest directing users to a preference center where they can manage their subscriptions granularly.
Marketer from Email Geeks explains that proper usage of lists is one consent given for each subscription list. Getting one consent, then putting the address in three lists, means that one unsub should remove from all three lists.
What the experts say5Expert opinions
Expert from Email Geeks suspects Gmail tracks mailstreams after a user has unsubscribed and sees continuing mail after a user has used the - google brokered - unsubscription option that probably won't be a positive for your mail stream reputation.
Expert from Email Geeks states that the sender controls the subscription management and can handle clicks on the list-unsubscribe header or the mailto: link in any manner they choose.
Expert from Word to the Wise explains that list-unsubscribe is more nuanced than a simple binary choice, you can control the experience to some degree. For example, when someone hits the Gmail list-unsubscribe button, you can send them to an email preference center rather than fully unsubscribing them.
Expert from Email Geeks explains if you're not using one-click unsubscribes then it's just the same as a click on your in-body unsub link, or can be if you so choose, and you can offer them more options.
Expert from Email Geeks advises clients to treat Gmail unsubscribes as a partial complaint because some come when the user hits “this is spam” and Gmail says “want us to send an unsub request?”
What the documentation says3Technical articles
Documentation from RFC 2369 explains the format and semantics of the List-Unsubscribe header. It specifies that the header can contain multiple unsubscribe mechanisms, giving the sender flexibility. However, it doesn't dictate the behavior of email clients when multiple options are present.
Documentation from RFC 8058 describes a method for one-click unsubscribe. This document is aimed at standardizing unsubscribe requests. It gives the recipient/client the power to control the actual unsubscribe action.
Documentation from Google Developers explains that the List-Unsubscribe header allows users to easily unsubscribe from mailing lists. While Gmail provides a one-click unsubscribe option, the actual handling of the unsubscribe request (single opt-out or options) depends on the sender's server-side implementation.
