Carly AI vs Notion Mail: Where to Go Now That Notion Mail Is Shutting Down
Carly is an AI-powered scheduling assistant that works over email and SMS. Unlike traditional booking links or calendar tools, Carly reads messy email threads she is cc'd on, understands context, and sends real invites that keep the conversation natural. You can forward Carly an email, send her a text, or send screenshots and images for her to process and add to your calendar. It's built for busy professionals who want a human-like assistant that just works, handling coordination and calendaring so you don't have to. ChatGPT could never be this useful.
Notion has confirmed that Notion Mail is shutting down on September 22, 2026, with an earlier June 30, 2026 deadline for HIPAA and other regulated organizations. If you built your workflow around it, you now need a place to land, so it’s worth being clear about what you’re actually replacing.
Notion Mail was an email client with AI features layered on top: a Gmail-backed inbox with a Notion-style interface, AI auto-labels, snippets, and scheduled send. You still opened it, read your mail, triaged it, and hit send yourself. Carly is a different kind of tool entirely. It’s an AI executive assistant that works your email and calendar for you over email and text, the way a human EA would. This comparison is about client-vs-assistant, and about the fact that one of these two is going away.

Why Carly is the Better Choice
You’re not just switching clients, you’re changing what the tool does. Notion Mail’s own reason for shutting down is telling: Notion found that more than half of Notion Mail users were letting agents handle their email and never opening the inbox at all. That’s the whole thesis behind Carly. Instead of a nicer window onto your inbox, you get an assistant that reads cc’d threads, drafts and sends replies, and books meetings without you sitting in the app. The migration moment is a chance to stop doing the triage yourself.
Carly does scheduling, which Notion Mail never did. Forward Carly an email, CC her on a thread, or just text her, and she coordinates the meeting end to end: proposes times, sends a click-to-book link, detects the other person’s timezone, writes the follow-ups, and drops it on your Google Calendar or Outlook. Notion Mail could compose and schedule-send an email, but it couldn’t run a scheduling back-and-forth for you. This is the core of what an AI email assistant should do and where a client stops short.
She lives over email and SMS, not inside one app. Notion Mail was a desktop-and-web Gmail client with no mobile app. Carly meets you where you already are. Text her a screenshot of a conference flyer to add it to your calendar, forward a booking request from your phone, or reply to her the way you’d reply to a person. There’s no inbox to open and no new interface to learn, which matters when the interface you learned is being turned off.
Carly isn’t locked to Gmail. Notion Mail only ever supported Gmail, no Outlook, no Apple Mail, no other provider. Carly works across Gmail and Outlook and handles both Google Calendar and Outlook calendars, so Outlook users who couldn’t use Notion Mail in the first place aren’t left out. If Gmail is your world, see the best AI assistants for Gmail for how this lane stacks up.
200+ integrations mean she acts, not just sorts. Notion Mail’s smarts stayed inside the Notion ecosystem. Carly connects to 200+ tools through a bring-your-own-API-key setup and acts on triggers, so a meeting confirmation can update your CRM, a new lead can kick off a follow-up, and none of it requires you to be the one clicking. Setup takes about two minutes, responses come back in about a minute, and she runs 24/7.
Notion Mail made sense if you wanted a prettier Gmail with a few AI touches and lived entirely on Google. Carly makes sense if you want the email and scheduling work actually done for you, over email and text, on either Gmail or Outlook. With the shutdown deadline set, the practical move is to export your Notion Mail drafts, scheduled emails, and snippets into Gmail before September 21, then decide whether you want another client or an assistant. If it’s an assistant, start with Carly or weigh the full field of Notion Mail alternatives.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
