I’ve used Text Blaze for years, especially for the repetitive emails I send from Gmail. With just a couple of keystrokes, Text Blaze fills in the subject line, jumps down to the body, writes the entire email, and then prompts me for any variables I need to customize. It’s been a great tool for making those messages faster and easier to send. Review collected by and hosted on G2.com.

The downside is that Text Blaze works only in Chrome. Of course, for those who compose in Gmail and Google Docs, there's no downside at all. Review collected by and hosted on G2.com.
