Email is the biggest problem
hiding in plain sight
We all spend hours on email. But we often reply late, and sometimes don't even reply. We then end up losing deals, blocking our teams, and missing our goals.
It's not anyone's fault. Email itself has not changed in decades.
With BrickStack Mail, this all changes.

Fly through your email
twice as fast as before.
Be more responsive to
what matters most.
Collaborate faster than ever before.
Built for teams that use
Gmail or Outlook
Works seamlessly with your existing email setup. No migration, no new addresses. Just a dramatically better experience on top of the tools your team already uses.

Respond faster to what matters most
We all get too much email. The urgent buries the important. We don't reply to our team or VIPs. And we miss notifications from tools like Google Docs. As a result, we lose opportunities, block our teams, and damage our reputations.
With Split Inbox, you can instead focus on what needs your attention. Split out emails from your team, your VIPs, or your most used tools — Google Docs, Notion, Asana — or anything else. Even when your inbox is overflowing, you'll respond fast where it matters most.
Have perfect timing with Send Later
Follow up on time, every time
Sometimes you write emails you want to land at the right time. Perhaps you're sending to a different time zone, or you want to send on a Monday rather than a Friday. With BrickStack, you can write an email now and send it later.
- Have perfect timing with Send Later

Collaborate faster than ever before
Share and comment with your team
You want to discuss an important email. It could be client feedback, a customer question, or an exciting partnership. What do you do?
Meetings are slow. Screenshots don't update. You could forward or bcc, but you'd have to do that every time you send and receive. With BrickStack Mail, you can share a live view of any email with your team. Your team can comment on the email, even if they don't use BrickStack. Rapidly unblock progress, and collaborate faster than ever before.




Track email opens in real time
See when people read your email
When you send an email with BrickStack, you see when people read your email — right in your inbox. No more wondering if your emails are getting through. You can finally follow up with perfect timing.
Automate phrases and entire emails
Type less and accelerate your team
No matter how fast we are, we all hit the same limit: the sheer time it takes to type. With Snippets, you can automate typing and push past this limit. Insert phrases, paragraphs, or whole emails. You can even include attachments, add people to CC, or BCC internal systems. You can also share Snippets with your team.
Communicate and collaborate more effectively
Share read statuses across your team
In BrickStack Mail, read statuses are shared across your team. Let's say a teammate sends an email and CCs you. Even though you did not send the email, you can still see when people read that email. Use team read statuses to handoff work, communicate better, and collaborate more effectively.
See when your team is replying
Avoid collisions with your team
Imagine the scene: you and your team get an urgent email, so you rapidly reply. But just after you hit send, your team replies as well. In the best case, you look disorganized. In the worst case, you contradict each other. In BrickStack Mail, you can see exactly when your team is replying. Know when your team is on it, avoid double work, and eliminate embarrassing collisions.
We'll even update your email for you
Check your calendar without losing flow
When you have a busy schedule, you can't waste time looking it up. Whenever you suggest a date, we'll show your calendar for that day. Looking busy? Just hit a shortcut, and we'll show the next day. We'll even update your email for you.
Schedule events at the speed of thought
No more back-and-forth. Share your calendar availability in seconds. Pick a time for yourself, or let your recipient choose. Either way, BrickStack adds the event to your calendar and sends a beautiful invite.
