Email tools are the backbone of digital marketing. They allow you to design, automate, and track your email campaigns effortlessly. From newsletters and product launches to drip sequences and abandoned cart reminders - these tools ensure your messages reach the right inbox at the right time.

AI tools for email marketing, on the other hand, elevate these capabilities by adding intelligence - analyzing open rates, personalizing subject lines, and even generating content automatically. They learn from audience behavior to deliver more relevant and timely communication.

That’s where AI assistants and modern email tools come in. These platforms use machine learning to:
