The Gatekeeper feature puts you in control of who’s allowed to email you - and who isn’t. The first time someone emails you, you get to decide if you want to get emails from them again: you can either accept the new sender or decline them. The senders are not notified if you block them in Gatekeeper.

Open Spark and use the ⌘, shortcut (press and hold ⌘ and press , ). Then, open the Inbox section > New Senders.

Alternatively, open Spark, click the Settings icon at the bottom left > Inbox > New Senders. Or, after opening Spark:

1. Click Spark in the Menu Bar.
2. Select Settings.
3. Switch to the Inbox section > New Senders.

Once you accessed the Gatekeeper settings, you can choose where to accept or block senders:

• On top of the Inbox
• Inside the email
• Accept all without asking

Using Gatekeeper

Once the Gatekeeper is on, you will be asked whether to accept or block the sender every time somebody with a new email address emails you. The senders are not notified regardless of your choice. For them, it looks the same as if they have never received a reply from you.

Bulk accept or bulk block

Besides accepting or blocking senders separately, you can bulk accept or bulk block all the senders with just a few clicks. To do so:

1. Open Inbox and click New Senders above the new sender cards or the … > Show All at the top right.
2. At the top right, click the thumb-up to accept all the senders or a thumb-down to block them.

Unblock the sender

To unblock the sender, open the Blocked section of the sidebar, open an email from the sender you want to unblock, and click Accept sender.
