Organization

Duet organizes your inbox

Duet automatically tags every email so you see certification inquiries and dive bookings first, gear questions second, and PADI alerts when you're ready. No more missing a group booking buried under equipment newsletters.

Drafting

Duet drafts in your voice

Duet learns your dive sites, cert requirements, and pricing. When a booking inquiry hits, it drafts a complete reply with trip details, what's included, and what to bring. You review and send.

Intelligence

Ask anything about your email

"How many divers are booked for Saturday?" "Draft a reply to Rachel with Open Water availability." Duet knows your inbox and schedule — just ask.

Testimonials

Loved by dive operators

Real people. Real inbox wins.

  • "I run boat trips Friday through Sunday and the shop is only open a few hours on Monday. Certification questions and trip inquiries pile up while I'm underwater. Duet drafts replies with my pricing, dive sites, and what's included — I review them between dives."

    Captain Mike T.

    Dive Boat Captain, FL

  • "We run dives, snorkel tours, and whale watches off the same boats. The email variety is insane — cert questions, group bookings, gear rentals, weather checks. Duet sorts it all and drafts replies that know the difference. Absolute lifesaver."

    Jen & Mark S.

    PADI Dive Center, HI

  • "Half my emails are 'what certification do I need for the wreck dives?' and the other half are 'do I need my own gear?' Duet handles both on autopilot. My response time went from hours to minutes."

    Jake R.

    Wreck Diving Charters, FL

  • "During summer we get 30+ emails a day about courses, trip availability, and equipment. I was losing bookings to shops that replied faster. Now Duet drafts everything and I just hit send between classes."

    Francesca D.

    Dive Shop Owner, CA

  • "I teach courses in the morning and guide dives in the afternoon. There's literally no time to answer email. Duet learned my course schedule, pricing, even my cancellation policy. Clients can't tell the difference."

01/

How does Duet Mail protect my email data?

Your security is our top priority. We use OAuth 2.0 for secure authentication, process emails in Gmail's secure environment, and never store your email content. All processing happens in real-time through Gmail's API, and we undergo Google's annual CASA security assessment to maintain the highest security standards.

02/

How does the email summary feature work?

Duet Mail uses advanced AI to analyze your email threads and generate a concise overview highlighting the key points, decisions, and action items. This helps you quickly understand the context without reading the entire thread.

03/

What permissions does Duet Mail need?

Duet Mail requires access to your emails to provide summaries, extract action items, generate content, and send your emails. We only request permissions we absolutely need. You can review and revoke these permissions at any time in your Google Account settings.

04/

What's included in the free trial?

The 14-day free trial includes full free tool access to all Pro features: unlimited email summaries, action item extraction, AI email writer (generating emails and drafts without any limits), and custom email templates. Just sign in with Google to start saving time on email management.

05/

Can I use Duet Mail with other email providers?

Currently, Duet Mail works exclusively with Gmail and Google Workspace accounts. We will be adding support for other email providers, including Outlook and Apple Mail in the future.

06/

Does Duet understand certification levels and course requirements?

Yes. Duet learns your specific courses — Open Water, Advanced, Rescue, Divemaster — along with prerequisites, duration, pricing, and what's included. When someone asks about getting certified, Duet drafts a reply with the right course details, schedule, and next steps. You review and send.

07/

I'm on the boat or underwater all day. Can I use Duet from my phone?

Yes. Duet works inside Gmail, so it works wherever Gmail works — including your phone. Drafts appear automatically in your inbox. Between dives or back at the dock, you review and send with one tap. Most dive operators tell us it saves them 1-2 hours of email time per day during peak season.

Spend your days underwater,
not buried in your inbox.
