Email unsubscribe links

[franzliedke]

See Google's mailing list guidelines:
https://support.google.com/mail/answer/81126?hl=en#unsub

Because Gmail can help users automatically unsubscribe from your email, we strongly recommend the following:

Provide a 'List-Unsubscribe' header which points to an email address or a URL where the user can unsubscribe easily from future mailings. (Note: This is not a substitute method for unsubscribing.)

Just to confirm, the unsubscribe link would literally just take us to the user's settings page?

That makes sense to me, since it's not like a regular newsletter.

While this seems fairly straightforward, our current mailing system provides a view, not a string. IMO the most elegant way to approach this is to subclass our own version of Laravel's Mailer, and define the ability to add a custom header and footer. The default footer could be a simple unsubscribe message. Thoughts?

On revisiting this issue, it seems like Google's recommendation is for a LIST-UNSUBSCRIBE header, not for an actual link in the body of the email. I think we should also have all emails sent extend an overridable template (which could facilitate a link as well)

[tankerkiller125]

I don't see why we can't do both a link and header, I believe that the swift email system should be able to add headers. At least for now, I think templates will have to wait until after stable.

[askvortsov1]

Apologies if I didn't word it clearly, I'm also in favor of both, with headers now and links after stable (I envisioned links being a part of templates: we could probably hardcode that into each individual email we sent, but IMO it's not that urgent, and wouldn't be a scalable solution). I think we should rename this issue to clarify that it's about headers, and make a new one (0.2?) for templates that would enable links

[franzliedke]

I believe an actual link is a legal requirement in many places.

[tankerkiller125]

@franzliedke You would be correct, I believe that GDPR in some way requires it and I know for a fact that the CAN-SPAM Act requires but that act is more limited to marketing (not flarum notifications) either way though having a link as well even without the template feature I think is important.

[askvortsov1]

This issue is only about the header; additional stuff is responsibility of extension devs for now.

[tankerkiller125]

After further research into this adding a header seems more difficult than it first appeared as we have no "central" location to do it from that I've been able to locate.
