SaneBox
Filters noise out of the inbox
Newsletters shelved for later
Follow-up reminders
Unanswered emails trackedSaneBox keeps tabs on messages that got no reply. Slashy also finds the threads waiting on you and can draft them.Partial
AI drafts in your voiceWritten from your sent mail and your edits, ready when you open the thread.
Drafts grounded in your CRM and meeting notes

Filtering is where SaneBox stops

The reply is waiting when you open the thread

Once the noise is gone, the replies still need writing. Slashy drafts them in your voice from the meeting you just had, the CRM record, and your past threads, so you approve instead of compose.

Questions & answers

Does Slashy filter like SaneBox?
Yes. Slashy sorts incoming mail by importance into tabs, so only what needs you is in front of you, and then it acts on top: drafting replies and tracking the ones you owe.
Do I keep my current email app?
Slashy is its own app, with a native Mac app, a fast web app, and a native iOS app. It connects to your existing Gmail, Google Workspace, Outlook.com, or Microsoft 365 mailbox, so your mail stays where it is.
How long does it take to set up?
Connect Gmail or Outlook with your existing sign-in and Slashy starts working. Nothing moves and nothing is migrated.
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.
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.
