Google Blog:
It can be easy to feel overwhelmed by the sheer volume of subscription emails clogging your inbox: Daily deal alerts that are basically spam, weekly newsletters from blogs you no longer read, promotional emails from retailers you haven't shopped in years can quickly pile up. With Gmail's new "Manage subscriptions" feature, you can view and manage your subscription emails, making it easy to unsubscribe from the ones you no longer want all from a single place.
With the new “Manage subscriptions” view, you’ll find your active subscriptions sorted by the most frequent senders alongside the number of emails they’ve sent you in the past few weeks. Click on any of the senders for a direct view of all the emails they’ve sent. Easily unsubscribe in one click, and Gmail will send an unsubscribe request to the sender on your behalf.
To find this view, click the navigation bar in the top-left corner of your inbox and select “Manage subscriptions.”
Gmail has always worked to keep unwanted emails out of your inbox. Our requirements for senders and tools like one-click unsubscribe give you even more control to choose and actually stop getting emails you no longer want. And the new “Manage subscriptions” view makes it easier than ever to manage what stays and what goes.
Alongside our efforts to keep inboxes safe, we’ve also prioritized giving users even more control over the messages they want to receive. Gmail blocks more than 99.9% of spam, phishing and malware, and we’ve recently rolled out new AI-based defenses which cut scam emails by 35%.
The ability to manage subscriptions in Gmail is rolling out now on web, Android and iOS to select countries.
