What is an AI Email Writer?

An AI email writer is an email writing tool that uses artificial intelligence to generate email copy.

AI email writers fall under a category of artificial intelligence called Natural Language Processing, or NLP. NLP uses a technology called Large Language Models (LLM). LLMs are algorithms that analyze how language works. The most famous LLM is OpenAI’s Generative Pre-trained Transformer or GPT model. It’s the LLM that powers most AI email writers.

Best Practices For AI Email

Follow these best practices as you add AI to your email writing process. And create high-quality content that increases open, click, response, and conversion rates.

Run a human check on all AI-generated email content
AI email writers should serve as assistants rather than creators. They help you research, ideate, and draft copy. So, even after you get AI output, provide suggestions as prompts, do spell-checking, add emotion, and edit the content. 

Experiment with different inputs
AI writers rarely get it right the first time. Generate more variations so you can choose the best or AB test different versions. If you want a subject line for an email campaign, you can ask the AI to write 5-10 subject lines choose the best 3-4, and run an AB test.

Write quality and specific prompts
The quality of the output of an AI email generator depends on the quality of your input. For all the AI email writers in this piece, you’d need to write descriptions and input ideas for email generation and if you don’t provide all the necessary details, you’ll get a generic output.
