Analyzing Email Marketing Impacts on Revenue in Home Food Enterprises using Secure SMTP and Cloud Automation

This review paper explores the intersection of secure email marketing, cloud automation, and revenue optimization in home-based food enterprises. As digital transformation reshapes microenterprise operations, email marketing remains a cost-effective and high-ROI strategy for customer engagement, retention, and brand visibility. However, home food businesses often lack the technical infrastructure to maximize these tools securely and efficiently. The study evaluates how integrating Secure Simple Mail Transfer Protocol (SMTP) with cloud-based marketing automation platforms—such as Mailchimp, Klaviyo, and AWS SES—can enhance deliverability, compliance, and personalized outreach. Emphasis is placed on key performance indicators (KPIs) such as click-through rates, conversion rates, customer lifetime value (CLV), and average order value (AOV). The review further investigates the role of automation workflows, behavior-triggered campaigns, A/B testing, and segmentation in driving customer re-engagement and reducing churn. Security considerations including domain authentication (SPF, DKIM, DMARC), data encryption, and compliance with regulations like GDPR and CAN-SPAM are also analyzed. Case studies of successful home food enterprises are reviewed to identify best practices and revenue-growth patterns. The paper concludes by recommending scalable frameworks and secure digital infrastructure that enable small food businesses to harness email marketing technologies while safeguarding customer data and enhancing long-term profitability.
