How to Automate and Organize Your Email with AI

You don’t need to switch email clients. Most popular tools already include AI or connect easily.

Option A: Gmail with Gemini (free)

1. Go to https://mail.google.com with your Google account.
2. Open any email and look for the “Help me write” button (pencil icon with sparkles) in the reply box.
3. If it doesn’t appear, check that Gemini is enabled on your account: go to https://gemini.google.com and accept the terms.

The free plan gives you suggested replies, automatic text completion, and the “Help me write” feature. For advanced features like Gemini integrated across the entire Google suite, consider Google AI Plus ($4.99/mo; confirm the current price on the official page before paying).

Option B: Spark (free and paid)

1. Download Spark from https://sparkmailapp.com (available for Mac, Windows, iOS, and Android).
2. Connect it with your Gmail, Outlook, or iCloud account.
3. Enable the Smart Inbox feature: it automatically sorts your email into Personal, Newsletters, and Notifications, for free.

The Plus plan ($10/mo; confirm on the official page) unlocks the full AI assistant to compose, rewrite, and translate emails.

A smart inbox separates what’s urgent from the noise so you don’t have to scroll through everything at once.

In Gmail:

1. Open Settings (the gear icon at the top right).
2. Go to the “Inbox” tab and enable “Customize your inbox”.
3. Select the categories you want separated: Primary, Social, Promotions, Notifications.
4. Move misclassified emails by right-clicking and “Move to” so Gmail learns from your corrections.

In Spark:

1. Open the app and look for the “Smart Inbox” section in the sidebar.
2. Emails arrive already separated into Personal, Newsletters, and Notifications.
3. If an email is misclassified, drag it to the correct category: Spark learns from your corrections.

Over time, the AI makes fewer and fewer sorting mistakes because it learns from your habits.

This is the most visible feature: instead of writing each reply from scratch, AI gives you a draft with one click.

With Gmail (“Help me write” button):

1. Open the email you want to reply to and click “Reply”.
2. Look for the AI icon (pencil with sparkles) in the text box toolbar.
3. Type a brief instruction, for example: “Thank them for the proposal and ask for more details about the price.”
4. Review the draft, edit if needed, and send.

With Spark Plus:

1. Open the email and click the AI button in the reply bar.
2. Choose between Quick reply, Detailed reply, or Your own prompt.
3. Adjust the tone (formal, friendly, direct) from the dropdown menu.
4. Edit and send.

Always read the draft before sending. AI can include commitments or information you didn’t want to confirm.

SaneBox works on top of any email client: Gmail, Outlook, Apple Mail, or any IMAP-compatible service. It doesn’t replace your client; it acts as a smart filter on top of it.

1. Go to https://sanebox.com and create an account (there’s a free 14-day trial).
2. Connect it with your email account using IMAP credentials or OAuth (if you use Gmail or Outlook).
3. SaneBox automatically creates folders like SaneLater (low-priority emails) and SaneBlackHole (senders you want to silence forever).
4. Move an email to SaneLater if it’s not urgent: SaneBox learns what types of senders go there.
5. Drag any email to SaneBlackHole: that sender will never appear in your inbox again.

With the Snack plan ($7/mo; confirm the current price on the official page before paying) you get 1 account and 2 filtering features. Higher plans add more accounts and features like follow-up reminders.

Automatic filters (or “rules”) process emails based on criteria you define, without you having to touch them.

In Gmail (Filters):

1. Open the search bar and type the criteria, for example the sender’s domain: from:newsletter@company.com.
2. Click the advanced search arrow, then “Create filter”.
3. Choose the action: Archive, Label, Mark as read, Delete, etc.
4. Click “Create filter” to activate it.

Rule ideas that work:

Email	Automatic action
Newsletters you don’t read	Archive and label “Newsletters”
Order confirmations	Label “Purchases” and mark as read
Social media notifications	Skip inbox and archive
Urgent work emails	Star and label “Urgent”

“Inbox zero” doesn’t mean checking email all the time; it means having a system to process it in batches. With AI it’s much faster:

1. Check your inbox twice a day (for example at 9am and 3pm), not constantly.
2. Reply immediately to emails that take less than 2 minutes, using AI drafts.
3. Archive or label everything that doesn’t require immediate action (filters do this automatically).
4. SaneLater or the Promotions tab accumulates non-urgent mail: review it once a week.
5. SaneBlackHole or unsubscribe for senders you never care about.

Problem	Fix
”Help me write” doesn’t appear in Gmail	Make sure Gemini is enabled on your account at https://gemini.google.com
Spark won’t connect to my email	Use the manual IMAP method in Spark Settings; check that your email allows third-party apps
SaneBox moves important emails to SaneLater	Move them back to your inbox: SaneBox learns and won’t touch them again
Gmail filters don’t apply to previous emails	Check “Also apply filter to matching conversations” when creating the filter
The AI draft doesn’t sound like me	Ask it to rewrite in a more specific tone or edit it directly
