Cloud email is an umbrella term that can describe personal email accounts hosted on remote servers, business email hosting with centralized account management and collaboration features, or cloud-based sending platforms for automated marketing and transactional messages. Compared with on-premises email infrastructure, cloud solutions generally reduce hardware, maintenance, and scaling costs while providing remote access, backups, flexible mailbox capacity, and resilience through distributed server resources, whereas locally hosted systems offer greater direct control and may suit organizations with strict security or regulatory needs but require substantial technical and financial investment. The appropriate approach depends on an organization’s size, security requirements, budget, technical resources, and operational needs. Common cloud mailbox providers include Google Workspace, Microsoft 365, Rackspace, Zoho Workplace, ProtonMail, and Tutanota, while services such as SendGrid, Mailgun, Mailchimp, Amazon SES, Postmark, and Sendinblue focus on bulk delivery, automation, analytics, integrations, and transactional email.
