Tiered to your home
The same four-tier framework powering KolBo Search and Browser chooses how strictly attachments and images are filtered before a message reaches you.
A kosher mailbox at kolbomail.com — with the same per-tier content standard you choose for the rest of your KolBo stack, applied before mail lands in your inbox. No LLM, no generative AI, no content composed on your behalf. Just deterministic filtering on every attachment and every image that arrives.
KolBo Mail’s kosher filtering is built and ready. Mailboxes are opening — reserve your address and we’ll let you know the moment yours is live.
An illustration of the inbound flow — every step is deterministic, none is generative. Filtering happens on the server, before the message ever reaches your phone.
Mail arrives at kolbomail.com over the standard secure path — anyone can write to you.
Dangerous or malformed attachments are stopped before anything inside is opened.
Every image is judged at the strictness your tier chooses — the same kosher standard as the rest of your KolBo stack.
Clean mail lands in your inbox; flagged mail is set aside in a review folder. Nothing is deleted on you.
Drag the dial. This is an illustration on sample messages — tiers are starter presets, and you compose your own standard. The strictness you pick is applied the same way across Search, Browser, and Mail.

KolBo Mail filters; it never composes, summarizes, or auto-replies. We never read, scan, or feed your email to any AI. Every decision is a deterministic rule on the bytes that arrive.
KolBo Mail inspects each inbound image and attachment, then routes the message to your inbox or a review folder — per your tier. Kosher, before it reaches you.
