How to get your email out of Gmail, Outlook and Notes — and what mailin does with it once it's on your device.
Step-by-step: getting your archive out of Gmail, Outlook, Apple Mail or Notes and into something you can search.
Google Takeout hands you a huge ZIP with an .mbox inside that nothing on your Mac wants to open. Here is how to unzip it, import it into mailin, and search the whole thing without uploading a byte.
A PST from an old Windows PC or an OST from a dead laptop, and no Outlook on your Mac. mailin reads both directly, up to 50 GB per file, and exports messages in formats anything can open.
Legacy Notes mail is usually kept but rarely searchable. mailin reads .nsf files natively on a Mac, up to 64 GB per file, and gets the messages into open formats that will outlast the platform.
The complaints we heard most, and what changed in mailin 2.0 to fix them.
Most parsers try to hold the whole archive in RAM. mailin 2.0 streams it in batches of 200 messages, counts oversized messages as damaged instead of crashing, and stops honestly on read errors.
A crash, a sleep, or a forced restart no longer means starting the import over. mailin 2.0 checkpoints every batch of 200 messages against the file's hash and picks up where it stopped.
Offset pagination gets slower the deeper you scroll. mailin 2.0 replaces it with a date-and-id cursor, splits the search index by year, and keeps the same UI.
A raw mail export is easy to get and nearly useless on its own. How to turn it into a private, searchable archive on your Mac before the account disappears.
Save the message as a file, open it in mailin, and read what the receiving server and the routing chain actually say. Nothing is uploaded, and no account is needed.

What each part of mailin does, and why it works the way it does.
Mailbox search finds one message you half-remember. Working through an archive needs operators, ranking and an index that stays fast at depth. Here is how mailin's search works.
A summary you cannot check is a claim, not an answer. How mailin's AI Assistant, Thread Story and AI Digest keep every output tied to the emails it came from.
A mail client shows one message at a time. When you need the shape of a whole archive, you need the timeline, the heatmap, the contact graph and the Executive Dashboard.
mailin 2.0 ships 47 guided workflows for forensic, legal, IT/SOC, journalist and personal jobs. Here is how the runner, sign-off and Documents & History work, with the full list.
Three overlapping exports mean the same message three times over. How Duplicate Manager removes exact copies, hands near copies to you, and makes the cleanup stick.
EML or PDF? CSV or JSON? Bates PDF with load files? A walk through each export format mailin offers, what it preserves, and the situation it is built for.
Custody, audit logs, Bates numbering, redaction and review workflows.
SHA-256 at import, an audit log where each entry signs the previous one, and Ed25519-signed exports. What each integrity feature proves and what it does not.
The Production Run workflow step by step: assemble a batch, code it, log privilege, apply Bates numbers and redactions, then produce a set with a load file and defensibility summary.
mailin scans on-device for emails, phone numbers, SSNs, card numbers and IPs, groups them by type and risk, and runs a Data Subject Request workflow with a redaction pass.
Headers, authentication results, phishing triage and incident workflows.
Working sensitive mailboxes offline, with provenance and cited findings.
No account, no cloud, no analytics — and exactly what the optional Cloud AI mode does.
Two Apple engines, a fallback chain, a provenance tag on every output, and a Cloud AI mode that is off until you turn it on with your own key. What runs where, and what is sent.
The App Store label says the developer collects nothing. Here is what backs that up: no mail-server code, StoreKit as the only default network use, and a Cloud AI mode that is off until you turn it on.
Tiers, Universal Purchase, and which plan fits which job.
A side-by-side of the three tiers at App Store prices, who each one suits, and the plain arithmetic on monthly versus yearly versus lifetime.
Buy once on the App Store and use mailin on all three devices. The archive stays where you imported it, only settings sync, and Apple Intelligence depends on the OS version.
