Built around the mailbox you already have

Run it from your phone

Slashy texts you when someone who matters writes. Text back to reply, send, or schedule, without opening the inbox.

Importance labels, no rules to build

Incoming mail is sorted by importance as it arrives, with the same labels Slashy uses for Gmail. You open the inbox to the mail that matters.

Walk into every Teams call briefed

Before each meeting Slashy drops a brief: who is on the call, the latest threads, the CRM context. Outlook meetings keep their Teams links.

Built for people who live in email

Shortcuts, scheduling, integrations, tracking, and team tools are built into the same intelligent inbox.

I was spending more time orchestrating AI than replying. Now I approve more than I compose. It just reads my mind.

Questions & answers

Does Slashy work with Outlook?
Yes. Slashy works with Gmail, Google Workspace, Outlook.com, and Microsoft 365, on web, desktop, and iOS. Your mail stays with Microsoft, and you read and write it in Slashy.
Can I use Gmail and Outlook together?
Yes. Both accounts appear in one All view, with importance labels and search covering both. Replies go out from the account that received the email.
How is this different from Copilot in Outlook?
Copilot works inside Outlook and answers when you ask. Slashy is the inbox: it sorts what needs you, has the reply drafted before you open the thread, and tracks the ones you owe. Your mail stays with Microsoft.
Is my email data safe?
Yes. Slashy has completed a SOC 2 Type II audit and encrypts data in transit and at rest. Your email is never used to train AI models, and you can revoke access anytime.
What does it cost?
Slashy is $30 a month, or $25 a month billed annually ($300 a year), for unlimited usage. The 7 day trial includes every feature, requires a credit card, and can be canceled any time.
