Can you set up an auto-reply for mentions of your old username?

On Twitter, there isn't a built-in feature specifically for setting up an auto-reply to mentions of your old username after you've changed it. However, you can manually reply to mentions of your old username to inform users of your new handle. Here's how you can approach it:

1. **Monitor Mentions**: Keep an eye on notifications for mentions of your old username. You can do this by regularly checking your notifications tab or setting up notifications to alert you of new mentions.

2. **Reply Manually**: When you see a mention of your old username, reply to the tweet with your new username. You can thank the user for their mention and politely inform them of your updated handle.

3. **Pin Tweet**: Consider pinning a tweet to the top of your profile announcing your username change. This way, anyone who visits your profile will immediately see the announcement and your new username.

4. **Educate Your Audience**: Encourage your followers and contacts to use your new username when mentioning or interacting with you. This helps spread awareness and reduces confusion over time.

5. **Third-Party Tools**: While Twitter itself doesn't provide auto-reply functionality for username changes, there are third-party social media management tools that may offer automation features for responding to mentions. These tools often allow you to set up automatic responses or schedule replies.

It's important to stay proactive in managing your username change on Twitter to ensure your followers and contacts are aware of your new handle. By actively monitoring mentions and engaging with your audience, you can effectively communicate your username change and maintain continuity in your interactions on the platform.
