Campaign Monitor is an email marketing tool with a focus on customization and ease of use. It uses drag-and-drop functionality to help users build out emails and newsletters for their audiences. These emails can be optimized for both PC and mobile viewing, ensuring a good customer experience regardless.

This makes email a relatively inexpensive method of marketing at scale for businesses. In fact, according to Campaign Monitor, nearly 60% of small businesses surveyed in 2021 planned to increase their spending on email marketing campaigns in the future. Email marketing is an excellent tool for any business looking to cast a wide net with a small budget.
