SaneBox alternative: CatchTheMail
SaneBox has been organising inboxes since 2010 and performs its task very well. This page explains where CatchTheMail takes a different approach, so that you can determine within a few minutes which of the two better suits the way you work.
Where SaneBox is strong
SaneBox is a filtering service. It connects to your mailbox, learns which senders matter to you and moves the rest into folders such as SaneLater, so that your main inbox shows only what its model considers important. It works with any provider, continues to work on your phone because sorting takes place on the mail server rather than in an app, and draws on more than a decade of behavioural data.
If your challenge is volume, meaning that too many messages arrive and most of them can safely be ignored, SaneBox is a mature solution to that problem. Nothing on this page suggests 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 share. You receive a private forwarding address, and the only messages we ever see are those you forward to it yourself.
This single design decision defines 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 examine one message in depth: read it in full, assess how urgent it truly is, explain why, and return a reply you can send without rewriting it.
The two products therefore answer different questions. SaneBox tells you what you should look at. CatchTheMail tells you what you should say, and how soon.
The question of access, stated plainly
Any tool that reorganises your inbox requires access to your inbox. This is not a criticism of SaneBox but a technical necessity: a message cannot be moved into a folder without permission to move it. The trade-off you accept is broad access in exchange for automatic sorting.
Forwarding reverses this trade-off. You give up automation, since nothing happens until you press Forward, and in return the tool never holds a key to your account. For freelancers and consultants whose inboxes contain client material covered by confidentiality agreements, this difference is often decisive, 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 forgo a sign-up than have you pay for something that does not address your needs. If any of the following apply to you, SaneBox or your current setup may be the better choice.
- You want your inbox sorted automatically, without any action on your part. Forwarding is a deliberate step, and if you do not forward a message, nothing happens.
- Your main challenge is the sheer volume of newsletters and notifications. Filtering addresses that better than analysis does.
- You want folders, rules and archiving within your mailbox. We are unable to make any changes to your mailbox.
- You want a single tool covering four mailboxes at once. Our value is delivered per message, not per account.
