SaneBox alternative: CatchTheMail
SaneBox has been sorting inboxes since 2010 and it is very good at what it does. This page explains where CatchTheMail takes a different route, so you can tell in a couple of minutes which of the two fits the way you actually work.
Where SaneBox is strong
SaneBox is a filtering service. It connects to your mailbox, learns which senders you care about, and moves the rest into folders such as SaneLater, so your main inbox only shows what its model thinks is important. It works with any provider, it keeps working on your phone because the sorting happens on the mail server rather than in an app, and it has more than a decade of behaviour data behind its decisions.
If your problem is volume, meaning too many messages arriving and most of them worth ignoring, SaneBox is a mature answer to that problem. Nothing on this page argues otherwise.
Where CatchTheMail is different
CatchTheMail does not connect to your mailbox at all. There is no account to link, no permission to grant and no password to hand over. You get a private forwarding address, and the only messages we ever see are the ones you forward to it yourself.
That single design choice changes what the product can and cannot do. We cannot move, delete or reorganise anything in your inbox, because we have no access to it. What we can do is take one message and go deep on it: read it in full, score how urgent it really is, explain why, and hand back a reply you can send without rewriting it.
So the two products answer different questions. SaneBox answers what should I look at. CatchTheMail answers what should I say, and how soon.
The access question, in plain terms
Any tool that reorganises your inbox needs access to your inbox. That is not a criticism of SaneBox, it is arithmetic: you cannot move a message into a folder without the right to move it. The trade you accept is broad access in exchange for automatic sorting.
Forwarding inverts the trade. You give up automation, because nothing happens until you press Forward, and in exchange the tool never holds a key to your account. For freelancers and consultants whose inboxes carry client material under a confidentiality agreement, that difference is often the deciding factor, and it is the reason CatchTheMail was built this way rather than as another connected assistant.

When CatchTheMail is the wrong choice
We would rather lose a signup than have you pay for something that does not match your problem. Pick SaneBox, or stay where you are, if any of these describe you.
- You want your inbox sorted automatically, without touching anything. Forwarding is a deliberate act, and if you forget to forward, nothing happens.
- Your problem is the sheer number of newsletters and notifications. Filtering solves that better than analysis does.
- You want folders, rules and archiving inside your mailbox. We have no ability to change your mailbox in any way.
- You want one tool covering four mailboxes at once. Our value shows up per message, not per account.
