Permission-based outreach, from your own inbox

Your Google Sheet, turned into a campaign that sends from your inbox

Features

Everything you need to run permission-based email outreach that lands

Personal sending, smart scheduling, and reply tracking for the contacts who opted in - without leaving your own Gmail and Google Sheets.

Sent from your own inbox

Every message goes out through your real Gmail, so it reads as a personal note and lands in the inbox - not a promotions tab. No third-party sending domains.

Sheet-native

Your Google Sheet is the source of truth. Pick a tab and columns and go - no CSV exports or imports.

Smart drip scheduling

Send in business hours, in each recipient's own timezone, with daily caps and warm-up built in.

Reply-aware follow-ups

Track replies and bounces, run multi-step sequences, and automatically stop following up the moment a recipient responds.

Deliverability

Lands in the inbox, because it comes from you

There is no third-party sending service to erode your reputation. Every message is sent from your own authenticated Gmail, so it arrives in the Primary tab and threads like a message you wrote by hand.

  • SPF, DKIM, and DMARC handled by Gmail
  • Delivered in each recipient's own timezone
  • One-click unsubscribe on every email

FAQ

Questions, answered

Is Decipher OS for cold email?

No. Decipher OS is for permission-based email only. You confirm that every recipient has consented before each campaign, and cold prospecting is prohibited in our Terms.

How does it send email?

Through your own Gmail account, one message at a time. There is no shared relay or third-party sending domain, so your email comes from your real address.

Can recipients unsubscribe?

Yes. Every email includes a one-click unsubscribe header and a clearly visible unsubscribe link, and opt-outs are honored immediately across all of your campaigns.

What Google data does it use?

Only what each feature needs: per-file access to the sheet you select, sending from your Gmail, and reading replies and bounces to your own campaigns. See our Privacy Policy for details.

Do I need to install anything?

No. Sign in with Google, point it at a Google Sheet, and you can send your first campaign in minutes.
