A missed message now reaches your inbox
Direct messages on Skydex ring a bell in the site's own notification list. That works well for people who open the site often, and most people do. It does nothing for the person who does not, and that person is exactly who a missed message matters most to. Somebody wrote to them and they will not know until they happen to come back and check.
Now, if a conversation stays unread for six hours, you get one e-mail about it. It names who wrote to you and links straight to the conversation. It does not repeat the message itself.
Leaving the message out of the mail is deliberate. A direct message is a private channel between two people, and the moment its words leave skydex.online for a mail server, they are sitting somewhere we do not control: an inbox, a phone notification banner, a forwarding rule. The mail only needs to say that something is waiting, not what it says.
It also will not flood you. If several conversations go quiet on the same day, you get one mail listing all of them, not one per thread. And each conversation only ever earns one mail per unread stretch: read it, or leave it, and a fresh mail only goes out the next time you are unaware of something new in that same thread. Muting a conversation, or blocking whoever wrote it, stops the mail exactly the way it already stops the bell.
This rides on the same mail sender that already tells station owners when their receiver has gone quiet, so it respects the same opt-out. One click anywhere in the footer turns off all of it, direct-message notices included. We do not yet split that into separate switches for different kinds of mail. If that turns out to matter to you, tell us.
Nothing about the bell changed. If you already read your messages there, this feature will never reach you, which is exactly the point.
