This page is designed to help you find out whether Sortfully is good and if it is the right choice for you.
Sortfully is an automatic filing service for Outlook and Microsoft 365. It moves each message into an Inbox subfolder, or tags it with a coloured category, based on the organisation that sent it. By default a message is only filed once you have read it, so new mail still lands in front of you and nothing disappears unseen. If you prefer, filing can happen instantly on delivery instead.
There is no AI in Sortfully. No model, no classifier, no LLM, and your mail is never sent to any AI service. Filing runs on deterministic rules you can read and edit: the sender's domain, your exact-match overrides, then Public Suffix List normalisation, so notifications.slack.com and hello@slack.com both land in one Slack folder, and .co.uk domains get correct names. You can group several domains into one folder, pin a domain to a folder you already have, exclude senders entirely, and choose move-or-tag per organisation. Every action is reversible.
Privacy is structural, not a promise. Sortfully never reads message bodies or attachments: the one code path allowed to call Microsoft Graph message endpoints uses a strict metadata field allow-list, and a CI gate fails the build if a content field ever appears. An optional detailed audit log records the subject line so you can see exactly what was filed; you can switch it off. Sortfully connects through delegated Microsoft Graph permissions only (Mail.ReadWrite, Mail.ReadWrite.Shared, MailboxSettings.Read), is a verified Microsoft publisher, and reads your existing inbox rules without ever modifying them. Tokens are encrypted at rest and you can disconnect at any time.
Optionally, a chunked, throttle-safe backlog cleanup sorts the mail you already have, with protected folders and a leave-recent-mail window so nothing current is touched.
Sortfully is built for Microsoft 365 first: individual mailboxes, shared mailboxes, and a Business plan with team management for firms. It is operated by a UK company, hosted in the EU.
Listed in
Filing by sender organisation
Mail is filed by the organisation that sent it, so every alias and subdomain from a company lands in one folder.
Move or tag per organisation
Each organisation can be moved to an Inbox subfolder or tagged in place with a coloured category.
File after read
By default nothing moves until a message has been read, so new mail never disappears unseen; instant filing on delivery is optional.
No AI
No model, no classifier, no LLM; filing runs on deterministic rules you can read and edit, and mail is never sent to any AI service.
Content-Blind
Message bodies and attachments are never read, enforced by a code-level allow-list and a CI gate, not just a policy.
Public Suffix list
Public Suffix List normalisation gives correct names for .co.uk, .energy and hundreds of other endings.
Overrides and exclusions
Group several domains into one folder, pin a domain to an existing folder, or exclude senders entirely; your rules always win.
Backlog cleanup
Sorts the mail you already have in chunked, rate-limited passes, with protected folders and an option to leave recent mail in place.
Undo anything
Every filing action is recorded and reversible from the dashboard or audit log.
Audit Log
A record of every filing with sender, destination and mode; a detailed option records the subject line and can be switched off.
Shared Mailboxes
Files shared mailboxes a delegate has access to, alongside personal ones.
Team Management
The Business plan adds team management for firms running multiple mailboxes with multiple users.
Most email organisers ask you to trust them: an AI classifier scores your mail and a privacy policy promises restraint. Sortfully is built so you don't have to take its word for it. It cannot read message bodies or attachments; the restriction is a code-level allow-list backed by a CI gate that fails the build, and filing runs on deterministic rules you can read and override. It is also the only one of its kind built for Outlook and Microsoft 365 first: delegated Microsoft Graph permissions from a verified Microsoft publisher, shared mailbox support, and read-only respect for your existing inbox rules, where SaneBox, Clean Email and Mailstrom treat Outlook as a second platform. And it behaves differently: mail is filed by sender organisation, so every alias and subdomain lands in one folder, and by default only after you have read it, so nothing disappears unseen and everything can be undone.
Sortfully was built by a UK founder who watched Outlook rules fail at scale: Exchange caps rules at 256 KB, one rule per sender domain does not scale, and rules only run while Outlook is open. The alternatives all wanted AI access to mail content, which is exactly what regulated firms cannot accept. So Sortfully does the opposite: deterministic filing by sender organisation, with a code-enforced guarantee that message bodies and attachments are never read. It launched in August 2026, operated by a UK company with EU hosting.
Sortfully contains no AI at all. Filing runs on deterministic rules you can read and edit: the sender's domain, your overrides, then Public Suffix List normalisation. And the privacy guarantee is structural rather than promised: the one code path allowed to call Microsoft Graph message endpoints uses a strict metadata allow-list, and a CI gate fails the build if a content field ever appears. Message bodies and attachments are never read.
Businesses and normal consumers can both benefit from Sortfully. Businesses on Microsoft 365, mainly professional services firms of 10 to 200 mailboxes (accountants, solicitors, surveyors, architects) and the IT admins or MSPs who manage their tenants. It also suits compliance-conscious firms that have decided against AI email tools, and individual Outlook power users.
