Sending emails to your clients might seem to be outdated at first glance, but it is a misleading option. Email Marketing remains an important part of digital marketing, serving as a reliable way to reach out to customers. According to Statista, email marketing revenue was $12.5 billion in 2024 and is projected to reach $18.9 billion by 2028.
The reason for this is the parallel evolution of tools that help carry out marketing campaigns. These tools are now powered by artificial intelligence. Gone are the days of sending generic emails and hoping for the best - emails still work, with open rates around 20%-30%, because AI allows sending emails that matter.
AI-driven email marketing goes beyond fixed patterns that traditional email marketing relies on. It uses algorithms that adapt and improve as they learn from customer interactions. AI tailors everything from personalizing email subject lines to predicting the exact time a person is most likely to open an email.
So, for large and small businesses alike, investing in AI-powered marketing automation is an important part of developing effective strategies. Here are some key features to look for:
AI copywriting - when AI helps you write emails. It can suggest subject lines, create the main text, or come up with calls to action so you don’t have to write everything yourself.
Predictive analytics – when AI analyzes your subscribers’ behavior and predicts their next actions. For example, it can determine which customers are likely to stop buying or when someone is most likely to make their next purchase.
Personalization – when AI can tailor each email to the specific recipient. AI can add the recipient’s name, show them products they’re interested in, or change the content based on their past behavior.
Send time optimization – when AI determines the best time to send each email so the recipient is most likely to open it.
Below, we will provide our pick of the best AI email services available today, their strengths, and pricing to help you decide which platform is right for your business.
