Subject: Your Visit to [City Name]

Dear [Friend's Name],

I hope this email finds you well. It's been a while since we last caught up, and I was wondering how you've been doing lately. I trust all is well with you and your family.

I'm writing to you today because I wanted to extend an invitation for you to visit [City Name] sometime in the near future. I know how much you love [City Name] and how much you miss it since you moved away. I would be delighted to have you stay with me for a few days and show you around some of the places you haven't seen yet.

[City Name] has changed a lot since you left, and there are a few new attractions that I think you might enjoy, such as [New Attraction 1] and [New Attraction 2]. Of course, we can also revisit some of your old favorite spots like [Old Favorite Spot 1] and [Old Favorite Spot 2].

Please let me know if you are interested in coming for a visit and if so, what dates work best for you. I would be happy to help you make arrangements for your trip.

In the meantime, I hope you're staying safe and healthy. If there's anything you need or if there's anything I can do for you, please don't hesitate to ask.

Take care and talk to you soon.

Best regards,

[Your Name]。
