Substack Messaging Extension Extension

The Substack Auto Messenger Chrome extension is a tool designed to simplify communication with your Substack subscribers. It allows you to send personalized or generic messages directly to your subscribers efficiently.

Here's how it works:

1) Install the Extension
- Download and install the Substack Auto Messenger Chrome extension from the Chrome Web Store.

2) Navigate to the Correct Page
- Log in to your Substack profile.
- Go to your Subscribers page at this exact link:
https://yournewsletter.substack.com/publish/subscribers
(Make sure there’s nothing added to the link after “subscribers.”)

3) Open the Extension
Click on the Substack Auto Messenger extension icon in your Chrome toolbar.

4) Compose Your Message
- Use the provided text box to write your message.
- Limit the recipients to up to 100 subscribers at a time (fewer is better to avoid overwhelming Substack's system).
- Double-check your message before sending.

5) Choose Your Messaging Options
- Unique Messages Only: Sends the message only to subscribers who have not yet received the same message. This ensures you’re not duplicating messages for the same audience.
- Empty Chats Only: Sends messages exclusively to subscribers you haven’t previously interacted with, perfect for welcome messages or initial outreach.

6) Keep the Subscribers page open while the extension runs.
The extension will indicate whether messages are successfully sent.

7) Best Practices
Message Size: Keep messages concise and meaningful.
Batch Sending: Avoid sending too many messages at once to maintain smooth operation.
Monitor Progress: Watch the extension's status updates to ensure all messages are sent correctly.

With this tool, you can efficiently manage your communication, welcome new subscribers, and strengthen engagement with your Substack audience.
