Generating Your First Reply

3 min read·Updated December 1, 2025

Replying to Emails with AI

Aeralis can help you craft the perfect reply to any email. It reads the original message and generates a contextual response.

How to Generate a Reply

Step 1: Open an Email

Open the email you want to reply to in Gmail.

Step 2: Open the Add-on

Look for the Aeralis icon in the right sidebar panel of Gmail. Click on it to open the add-on.

Step 3: Click Generate Reply

In the add-on panel, you'll see the Generate Reply button. The add-on automatically detects that you're viewing an email and shows the reply options.

Step 4: Describe Your Response (Optional)

In the text area, you can describe what you want to say in your reply. For example:

"Accept the meeting invitation and confirm I'll bring the quarterly reports. Ask if they need anything else prepared."

Or simply:

"Politely decline, I'm not available that day. Suggest next week instead."

💡 Tip: You can also leave this field empty! Aeralis will generate an appropriate reply based on the email context and your profile settings. This is especially useful when you've configured your profile with custom instructions and grounding tools that provide enough context for the AI to craft a relevant response.

Step 5: Choose Reply or Reply All

  • Click Generate Reply to reply only to the sender
  • Click Generate Reply All to include all recipients

Step 6: Review and Send

The AI will generate a reply and create a draft. Review the content, make any edits, and send when ready.

How It Works

When you generate a reply, Aeralis:

  1. Reads the original email - Understands the context and what's being asked
  2. Analyzes the thread - Considers previous messages in the conversation
  3. Applies your profile - Uses your tone preferences and custom instructions
  4. Generates a response - Creates a relevant, contextual reply

Tips for Better Replies

  • Be specific about your intent - "Accept and thank them" vs just "reply"
  • Mention key points - What specific information should be included?
  • Specify the tone - Especially if it differs from your default profile
  • Reference the original - "Address their concern about the deadline"

Reply vs Reply All

  • Reply - Responds only to the sender of the email
  • Reply All - Responds to the sender and all other recipients (CC'd people)

Use Reply All when the whole group needs to see your response. Use Reply for private responses or when the information is only relevant to the sender.
