9 Business-ready AI Tools For Speedier, Superior Email Copywriting

AI email copywriting tools

Generative AI has changed the way we look at plagiarism. Because AI can bang out technically ‘unique’ content, it is harder than ever to tell the pukka from the fake. It is a legitimate concern, one that involves ethical considerations.

As Des Brown, GM at TouchBase Pro, says, “Making sure your ideas are original and not merely bad copies of existing content is critical. You also diminish trust by simply copying work that an AI engine generates.”

The implication is clear: don’t rely exclusively on AI for content creation. Two reasons: it is ethically questionable. And, because gen AI is far from perfect, human monitoring is all-important.

With that in mind, let’s look at the nine AI tools that can transform your email copywriting.

1. Unlayer

If you want your subscribers to read your email, you must start with a blink-stopping heading in the email body. Give the viewer a compelling reason to keep scrolling.

Unlayer’s AI-enabled Smart Headings feature can help you come up with send-ready headlines for your email. Enter the relevant keyword, and the AI tool will crank out a list of actionable suggestions.

To that end, has made it possible to create customized newsletters for subscribers. Choose your preferred newsletter template, and send highly personalized newsletters to your subscribers with minimal effort.

Depending on which of your articles/blog posts generate the most interest, will come up with a reader-optimized selection of the best content in your newsletter.


3. Omnisend

Wrapping Up

Generative AI has had its fair share of controversies. And they can all be traced to the question of trust.
