Integrations refer to the process of connecting different systems, applications, or tools to work together seamlessly. For example, when you link your email service with a project management tool like Trello, it allows you to receive notifications directly in your inbox. This makes it easier to manage tasks without switching between different platforms. By using integrations, businesses can streamline their workflows and improve efficiency. For instance, connecting Salesforce with Mailchimp enables automatic updates of customer information, ensuring that marketing campaigns are always targeting the right audience. Overall, integrations help save time and reduce manual work, leading to better productivity.
