Every capability, in plain English.

Built for the inbox you actually live in.

A short tour of what Mailinizer does — and the boring engineering that makes it boringly reliable.

The deep cuts

The features behind the features.

Sorting into fifty categories

Every new message lands in one of fifty categories, grouped into ten: Primary, Work, Invoices, Codes, Events, Shopping, Social, Newsletters, Marketing and Low Priority. Each shows how sure the AI was, and one tap recategorizes it.

A daily brief at the hour you pick

The replies you owe, the deadlines in the next two days and the mail that mattered in the last 24 hours, with a link to every message it mentions. Included with Pro, free for your first 7 days.

Summaries and Smart Reply

Open an email for a summary with its action items and deadlines, then answer with a Smart Reply in the tone you want. Summaries come with Pro.

Write with AI, send it yourself

Refine, shorten, expand, translate or match your voice on any draft, from any connected account. Nothing goes out until you press Send.

Waiting on

Mailinizer spots threads where you sent the last message and nobody has answered in three business days. Approve the nudge it drafts, and undo it for 15 minutes after it's sent.

Rules you write as a sentence

When a message is from someone, mentions something or has an attachment, then label, star, mark read, archive or categorize it. Regex if you want it, no AI involved, and you can run rules on mail you already have.

Every attachment in one place

The Files tab gathers attachments from all your inboxes, with filters, PDF preview (password-protected ones too) and ZIP export.

Unsubscribe and cleanup suggestions

Each night Mailinizer looks for newsletters you never open and notifications you can clear, and suggests one-tap fixes. Automatic unsubscribe is off by default; when it's on, each one waits 60 seconds for you to undo it.

Works with the inbox you have

Gmail and Outlook (Microsoft 365 and Hotmail) through OAuth. iCloud, Yahoo, Fastmail and any other IMAP account with a password. Labels sync both ways.

In eight languages

English, German, Spanish, French, Italian, Portuguese, Arabic and Persian, with right-to-left layouts for Arabic and Persian.

Security & privacy

Boring on purpose. Always.

Your mail is the most sensitive data you own. We treat it that way.

AI is opt-in

AI processing starts switched off. When you turn it on, the AI provider receives the sender, subject, the opening of a message and its attachment names, for inference only and without training rights.

Sorting never deletes your mail

Categories sit on top of your mail. Moves and labels can be undone for 15 minutes, and every automatic unsubscribe waits 60 seconds for you to undo it.

Encrypted in transit, credentials encrypted at rest

TLS everywhere. OAuth tokens and mailbox passwords are stored AES-256-GCM encrypted; the database is reachable only from our private network.

Hosted in the EU

All mail bodies, drafts and derived data live on servers we operate at Contabo GmbH in Germany. We don't offer a non-EU option today.

Trust

AI is opt-in.

Your mail stays yours.

AI processing starts switched off, and your rules work without it. Switch it on and the AI provider gets the sender, subject, the opening of a message and its attachment names, for that request only and never for training.
