Big Mail brings a fresh new look to your inbox, as well an entirely new way of working with it. From advanced A.I. categorisation, to its carefully crafted design, the result is less time organising your inbox, and more time enjoying it. And best of all it works with your existing email address.

Your emails organised in the blink of an A.I.
Big Mail can intelligently and automatically organise your inbox into distinct categories (we call them Scenes). Whether it's elevating important conversations, or filing away your latest purchases, Big Mail has you covered.

Let your emails make a Scene
Rather than present every email in the same way, a Scene in Big Mail optimises the layout specifically for it. It makes newsletters inviting, purchases easy to find, and conversations a breeze. With six Scenes – Conversations, Newsletters, Purchases, Notifications, Events and Files – your inbox has never been more organised.

Reply now or Reply Later.
Ever receive an email but can't reply to it right away? Big Mail has a built in "Reply Later" workflow so you can pick it up later on. It even syncs across all your devices

Approve new senders
With Big Mail you decide who gets in your inbox. The first time someone emails you they appear in The Bouncer, then you decide if you want to receive their messages.

Newsletters, taken to the edge
Enjoy a distraction free reading experience with Big Mail's immersive full screen reader mode for newsletters. Controls are tucked away, letting your newsletters shine.

And so much more:
- Detached attachments
- Glancing: mark messages as read just by scrolling past them
- Sender profiles
- Dark mode
- Unified inbox
- Magic avatars
- Spy tracker blocker
- IMAP support

Great idea, premature release

I would give the idea 5 stars, but, as released, 1 star for execution. I tried to give it an hones effort for the 2-week trial but there were too many bugs, including crashes in the macOS version.

I was excited in the lead-up to the release and do believe the app has great potential to become a stellar email client. It has some great key ingredients, not least of which is the AI email category sorting, with easy re-categorization. The "landing page" with the latest conversations, newsletters and notifications is fantastic.

What needs work: it should be easier to mark an email as unread, perhaps through a customizable toolbar; I should be able to delete emails with "Delete" key AND from the category tabs, not just from the Everything window. The refresh/fetching of new email should be much faster. The font editing toolbar should be embedded when composing emails. Attachments should appear within the message being viewed and not require you to switch to the attachment tab to view. Also, printing. I HAVE to be able to print and/or save an email.

There are probably a few other things, but, for this price and given the importance of email, I hoped that Big Mail would be able to hit the ground running, at least with some of these basics worked out. I'd love to see what this app is like in a future version.

Not Ready for Release and WAY too Expensive

This application is rough. Really rough. Very basic features are missing. There are almost zero keyboard shortcuts. It's also kinda confusing, and there is almost no support anywhere to get an idea of what the buttons actually do and how the different sections are supposed to work. The macOS version isn't syncing with the iPad or iPhone.

And the developer is charging a high price for this sub-par experience. There is no free tier. It's $10 per month or almost $80 per year. I don't think that is a sustainable business model even if the app was great. Look at HEY mail. Their app was MUCH more robust and bug free, and that only costs a few dollars more than Big Mail.

I question the decision making of this developer. This app shouldn't be released yet. It's definitely not ready. And this is your email. I would stay away from this app for a while until these bugs get worked out and they add the most basic of features. But I'm not sure I'm ever going to try it again.

Awesome concept, just not ready for prime time

This is not to bash the app at all but it’s just not ready for purchases. You’re going to experience crashes, issues getting emails synced, issues reading your email, and even, and this is what made me uninstall, a bug where you can’t paste into an email you’re composing. I was trying to paste info for a foreign visa application, and I was stressed enough without fighting this app. I think it needs another few releases just focused on bugs before letting people purchase it.
