HubSpot is an email marketing tool that enables you to enhance your marketing productivity without relying on others. With HubSpot, you can create, personalize, and optimize your marketing emails without waiting for designers or IT. It provides you with the ability to create professional email campaigns, complete with calls to action and branding options. The tool offers features like custom layouts, drag-and-drop editing, and more. Although the basic marketing features are available for free, HubSpot is a freemium tool, meaning that users can opt for the paid version to create more fun and attractive campaigns.
