How do you organize your email inbox with AI?

You organize your email inbox with Sintra by giving the helper one prompt. Cassie pulls emails by date, sender, or subject. It drafts replies in your voice. It sends emails from chat. Vizzy can draft and send business emails too. Both work with Gmail and Outlook. Gmail users can also turn on Cassie's Inbox Manager. That's a beta automation that labels incoming emails and writes draft replies in the background.

The full setup takes about 10 minutes.

How to organize your emails in few steps with Sintra

Each step is one prompt. Send them in any order. Run the first six daily, the next three when you need them, and the last two as one-time setup.

Step 1. Pulling today's emails

Cassie finds emails by date. Tell her the platform and the time range.

Prompt: Cassie, please provide the emails I got today from Gmail.

Output: a list of today's emails from your inbox.

Step 2. Pulling emails from a specific sender

Cassie filters by domain or full address. Useful for one contact, a recruiter, or a newsletter source.

Prompt: Cassie, please retrieve all emails sent from @linkedin.com from my Gmail.

Output: a list of emails from that sender.

Step 3. Pulling emails about a specific topic

Cassie filters by subject or keyword. She matches your request as closely as possible.

Prompt: Cassie, please provide all emails that mention "invoice" in any way from my Outlook.

Output: a list of matching emails.

Step 4. How to combine filters for precise pulls

Cassie can mix date, sender, and subject in one prompt. This gives you the sharpest search.

Prompt: Cassie, please provide all emails from @linkedin.com that mention "interview" sent from May 1st to May 12th.

Output: a focused list. If Cassie pulls too many at once, she can struggle to process. Split the date range into smaller chunks.

Step 5. Review what you sent recently

Cassie pulls your sent folder. She filters by date or subject, but not by recipient.

Prompt: Cassie, please provide the emails I sent in the past 7 days from my Gmail.

Output: a list of your sent emails for that period. Useful for quick follow-up checks.

Step 6. Get a daily inbox summary

Vizzy's Daily Summarizer pulls your emails and calendar events from the past 24 hours. It runs once a day. You see what came in and what's on your schedule in one short update.

Setup: Activate the Daily Summarizer in Vizzy's chat. Works with Gmail and Outlook.

Output: a daily update with your most recent emails and calendar events.

Step 7. Employ Cassie to draft a reply

Cassie writes a reply to any email she pulled. She uses your Brain AI context for tone and key facts.

Prompt: Cassie, please draft a reply to the latest email from [sender]. Keep it brief and friendly.

Output: a reply draft. Click "view" to check the recipient and subject. Then click Send or Cancel.

Step 8. Send a new email from chat

Describe the email. Cassie drafts it. You add the recipient. You review and approve.

Prompt: Cassie, please create an email draft to [recipient] about [topic]. Keep it short and professional.

Output: a draft you can review. Click "view" to confirm the recipient. Click "Send" to send. A green checkmark with "success" confirms it went out.

Step 9. How do you add Cc or Bcc recipients

Tell Cassie in the prompt. She adds the extra addresses to the draft.

Prompt: Cassie, please draft an email to [recipient]. Cc [[email protected]]. Subject: [topic].

Output: a draft with the Cc or Bcc field set.

Step 10. Turn on Cassie's Inbox Manager

For truly organized inbox turn on Cassie's Inbox Manager. It labels your incoming Gmail and writes draft replies in the background. Setup takes a few minutes once you have beta access.

Setup steps:

1. Request beta access from Sintra customer support.
2. Go to app.sintra.ai/automations/inbound-replier.
3. Finish the onboarding flow and connect Gmail.
4. Wait for the checkmarks.

What happens next: New labels appear in your Gmail. The last 10 to 20 emails get sorted on setup. Every new email gets labeled. We offer three main email categories for which Cassie writes draft replies for emails tagged "To Respond", "Cold Email", or "Awaiting Reply" - those are the labels visible inside Sintra. Other categories stay in Gmail only. You approve every reply before it sends.

One honest note: Auto-replying is not supported. Cassie won't send without your approval. Bulk actions (archive, delete, move) happen in Gmail, not in Sintra. Files and image attachments are not supported in Inbox Manager.

Step 11. Train Cassie for better replies

Cassie's reply quality depends on Brain AI. Add Q&A snippets with clear labels and keep them current.

How to do it:

• Snippet title: What is our contact number?
• Snippet description: Our number is +1 555 0100.
• Use clear category labels in titles: [contact info], [product info], [pricing].
• Edit snippets when info changes. Outdated snippets give outdated replies.

Output: sharper, on-brand replies that reflect your current business info.

Manual email management vs. AI email management with Sintra

Tips for better AI email organization

Five things that improves the outcome the most.

• Set up Brain AI before your first session. Cassie reads Brain AI for every reply. Without Q&A snippets on your products, prices, and contacts, replies come back generic. Use clear titles like [product info] or [pricing].
• Always say Gmail or Outlook in your prompt. Cassie needs to know which platform to check. Saying "my inbox" alone can confuse it, especially if you have both connected.
• Break up big retrievals by date. If Cassie pulls too many emails at once, she can struggle to process. Split a month-long pull into weekly chunks.
• Approve every send. Cassie won't auto-send. She waits for your "Send" click. Inbox Manager drafts sit in your Gmail drafts folder until you approve them too.
• Pair Daily Summarizer with Inbox Manager. Vizzy's Daily Summarizer gives you the overview. Cassie's Inbox Manager handles the sort-and-draft in the background. Gmail users get both layers working together.

Organize your inbox in the next 10 minutes

Cassie pulls, drafts, and sends from chat. Vizzy gives you a daily overview. Gmail users can add Cassie's Inbox Manager for background sorting. Together, they turn a chaotic inbox into a system that mostly runs itself.
