Gmail doesn't have a direct way to reuse or resend sent messages. However, there are three alternative ways to make it possible:

1. Forwarding

The simplest way is to just forward the message, change "To" address accordingly, and delete the marking (---------- Forwarded message ---------).

2. Canned Responses (Templates)

Canned Responses make it possible to insert a set of sentences you use frequently. For details, please refer to the page linked below:

3. Create a message by clicking a URL link

You can also make use of a special URL to quickly compose your message. For details, please refer to the link below:
