Best AI Email Assistants for Marketers and Entrepreneurs

What are AI email assistants, and why are they important?

AI email assistants are designed to optimize how we create, send, and manage emails. For both marketers and business owners, AI email assistants can be a strategic tool — they can save time, money, and effort, while boosting productivity and performance. How do they do it? Easy — email assistant generates your emails and email campaigns, including the content of your copy, images, CTAs, design, etc. Another way to work with them is to use an email assistant as a creative partner: it can brainstorm ideas, suggest insights, and give feedback on your own plans. Whichever path you choose, the result will be the same — more personalized, relevant, and impactful marketing emails.

How do they work?

AI email assistants work by leveraging machine learning and deep learning. They analyze your email content, audience engagement, and response patterns to provide actionable insights and recommendations. 

Usually, AI tools incorporate either Gen AI models, like OpenAI’s GPT, for example, or predictive analytics. All they need from you is a prompt — description of the task, audience specification, and details that you find important for the best result. In many cases, AI assistants can perform in multiple roles, like copywriter, designer, marketer, or data analyst. 

To give you an example of how this works, we asked Selzy’s AI assistant in “AI generator” mode to create a promotional email for a new beauty concealer. The prompt was very simple. We added a few mistakes, just to check if AI would be triggered by them (he was not!). The picture, text, buttons, and design overall — all his.

We might add that any AI needs heavy input from humans — sadly, it’s not a Michelin star restaurant, but more like a test kitchen with an infinite number of helpers. And you need to treat it like such — improving and tweaking both your prompts and the results you got. If you are not sure about what to ask for yet, you can train on the best marketing prompts for ChatGPT. And one idea is to ask it to improve your prompt to your email assistant. Yes, we are at the point where AI can help us with other AIs.

4 benefits of using AI email tool

AI email assistants work by leveraging machine learning and deep learning. They analyze your email content, audience engagement, and response patterns to provide actionable insights and recommendations. Here are only a few applications of AI email tools:

1. Saving time on writing and optimizing content: AI tools can suggest optimal subject lines, content tweaks, and even entire email drafts based on your audience’s preferences and past engagement data. For example, when using ChatGPT for email marketing, you can draft newsletters, promotional content, or follow-up messages in minutes while keeping your communication consistent and engaging.
2. Scheduling and sending emails: These tools can determine the best times to send emails to maximize your open and click-through rates. They can also suggest adjustments in your sending times, email content, format, and sending patterns to avoid being marked as spam or ignored. AI email assistants significantly enhance email deliverability, which sets them apart from traditional email marketing software. AI tools identify and remove invalid or unresponsive email addresses, thereby reducing bounce rates.
3. Predictive analytics: AI email assistants can forecast the success of your campaigns, allowing you to make data-driven decisions. AI email assistants can track open rate and click-through rate, offering actionable suggestions to improve future campaigns. They can also automate the segmentation of your audience based on various criteria, meaning you can effortlessly send targeted campaigns to different customer groups without manually sorting through your contact list. They can predict trends and customer behaviors — and a lot of brands are now heavily rely on such features. It’s one of the important email marketing lessons from recent years: the right AI tool has already increased marketing-driven purchases by over 35% for some companies.
4. Personalization at scale: AI writing tools and email-generating tools help you achieve a more personalized level of communication with large audiences. More so, now it can happen in real time, with customers getting emails created just for them and just in the right time frame. Once again, predictive analytics and data insights help them with the task. For humans, that means improved engagement and customer loyalty.

3. Initial setup time: Setting up AI email assistants can be time-consuming, as they require initial data input and time to learn your brand voice and audience preferences.
4. Keeping content authentic: AI-generated content might not match your brand’s tone. Regular monitoring and tweaking are necessary to maintain the quality and authenticity of your emails.
5. Cost considerations: Take another good look at both the tool that caught your eye and your goals before spending your entire marketing budget.
