Mail Assistant
Visibility and power over every Apple Mail account — see which senders are filling your mailboxes, how much room they take, and clear hundreds of messages in one pass.
Mail Assistant is here to make your experience with Apple Mail much better — letting you manage your accounts with greater visibility and control.
Everything stays on your Mac. Mail Assistant does not require network permission or account login. It reads the mail Apple Mail already downloaded and never sends any of it anywhere. It works directly with Apple Mail.
Apple Mail handles your mail well. What it does not do is show you the shape of it. It can tell you how big an account or a mailbox is, but not which senders are behind that size, how many messages each has sent, how much space they take, or which of them you have never once opened. Mail Assistant allows you to perform advance searches and combination of search type providing precise search ensuring that you find what your looking for. It can give you a detailed report based on Senders and also show a trend with a chart displaying amount of messages from senders per week and more.
Mail Assistant lets you act on every account at once, with a confirmation first and a way back afterwards. Visibility, and the tools to do something with it.
Features of Mail Assistant
Designed across four intuitive tabs: three powerful modules engineered to elevate your Apple Mail workflow, and a final control hub offering complete data transparency and direct access to support
Click any screenshot to enlarge it — click outside, or press Escape, to close. Where a tab has more than one, the row scrolls sideways.
Search once, then act on what you find
Search by sender, subject, date, folder, attachment name, or words inside the message body — every account at once or a selected one. Start typing a sender and it offers matching addresses with the message count for each.
The results are not a dead end. Each row is tagged with the account it came from, and you can select any of them and move, trash or mark read/unread the whole selection in one pass. Searches you run often can be saved, and any result list exported as a spreadsheet.
See who is actually filling your inbox
Every sender ranked by how many messages they have sent you and how much space those take — and sorting by size is usually the surprise. A handful of senders account for most of a mailbox. Each row opens out to show which folders their mail is sitting in.
From here you can move a sender’s mail to a folder or to Trash, mark it read or unread, look for their unsubscribe details, or mark them as one to keep so they are never staged for deletion again.
Catch it before it piles up
Trends watches the shape of your mail rather than its contents: how much arrived each week and when the busiest week was, new senders you have never once opened, addresses you have not heard from in over a year, and what is stacking up unread now.
Each list can be filtered, re-sorted and opened up, and the sentence above the rows always states which rule put them there and which order you are looking at. Lists can be narrowed to addresses you have never written to, so the people you actually correspond with stay out of the way. Trends changes nothing by itself — it tells you where to look.
You can see exactly what it is holding
Settings shows the folder access you granted and lets you withdraw it, how large the search index is and how much of your mail is in it, and every mark you have put on a sender. It also lists, in plain words, everything the app keeps on your Mac and how to remove all of it.
Acting on what you find
Hundreds of messages in one pass
Move to a folder, move to Trash, or mark read or unread — for several senders at once, across different accounts, in a single run. Every action shows a confirmation naming exactly how many messages it will affect, reports back how many were actually changed, and can be stopped part way without losing the work already done.
Stop the next one from arriving
Deleting today’s newsletter does nothing about next week’s. Mail Assistant reads the unsubscribe details the sender put in their own message headers and hands the link to your browser. It also tells you whether unsubscribing is the right move: for a sender you have written to before it usually is, and for one you have never heard from it usually is not.
Put it back
Restore returns messages from Trash to the folders they came from. Mark as Read is undone by Mark as Unread. Recent actions keeps a record of everything you did, so nothing you try here is a one-way door.
Requirements
macOS 14 or later, and Apple Mail signed in to at least one account. Mail Assistant works alongside Apple Mail rather than replacing it — your mail stays exactly where it is, and anything this app changes is a change Apple Mail itself carries out.
