How do I disable the annoying "😢 You've been missed!" emails?

I got an annoying “:cry: You’ve been missed!” email but there’s no where to manage subscriptions and the unsubscribe link in the email 404’s.

I tried the built-in gmail unsubscribe, but there was no confirmation anything happened as it just showed the homepage.

I like the app, but the sad begging email to come back is a huge turn off. There needs to be a way to turn off different types of emails. Not having a proper unsubscribe facility is going to make people report it as spam to stop it and that’ll trash your email open rates.

Right, this is a direct violation of the US CAN-SPAM act, and the equivalent in Canada. The requirement is for a one-click removal without further action (such as logging in, clicking another button, typing an email address etc) required.
