The alternative to Outlook rules that never needs maintaining.
Outlook rules are brittle if-this-then-that filters. The moment a sender, subject line or workflow changes, they break — and you're back in the rules editor. mailbud reads each email by meaning and files it for you, with nothing to maintain.

Re: Q2 invoice & remittance
Attaching the February invoice with the corrected remittance note. Payment due the 28th…
mailbud reads —
“Vendor invoice. File under Invoices.”
- Microsoft 365· Native Graph API
- Zero maintenance
- Never sends for you
- EU hosting
Everything rules can't do
Reads meaning, not keywords
mailbud interprets what an email is actually about, instead of matching a fixed sender or subject string.
Adapts on its own
When senders, wording or workflows change, there's no rule to rewrite — it just keeps filing correctly.
Asks when unsure
Rules fail silently. mailbud holds ambiguous mail in a review queue with its reasoning shown.
Learns from corrections
Each fix becomes a private example, so it gets more accurate — something a static rule can never do.
Plain-language setup
Describe a folder in one sentence instead of stacking conditions, exceptions and stop-processing flags.
Safe by design
It only reads and files. It never sends, replies or forwards — and your mail never trains an AI model.

Rules fail silently. mailbud asks.
The worst thing about a rule isn't when it works — it's when it quietly stops working and you don't notice for weeks. A renamed sender, a new subject format, and mail starts skipping the folder it should land in.
mailbud never guesses in the dark. When confidence is low it holds the email in a review queue with the reasoning attached, so you stay in control of the edge cases while the obvious mail files itself.

Schedule for the Thursday read-through?
Reads like a meeting request, but this sender has never appeared in Meetings before — Personal is also plausible.
Outlook rules alternative — FAQ
Why are Outlook rules so hard to maintain?
Rules are fixed conditions on sender, subject or keywords. Real mail changes constantly, so rules break or overlap, and you end up managing a growing list of conditions, exceptions and stop-processing flags.
How is mailbud different from Outlook rules?
Instead of matching fixed conditions, mailbud reads and interprets each email, then files it into the folder you described in plain language. It adapts as your mail changes and learns from your corrections.
Can I keep my existing Outlook folders?
Yes. mailbud files into your real Outlook folder structure, nested under a prefix you choose. You don't migrate anything.
Do I have to delete my current rules?
No, but most people turn them off once mailbud is filing reliably, because there's nothing left for the rules to do.
