Enterprise Email Marketing Infrastructure

Overview:

At Teknologix, I engineered a self-hosted enterprise email infrastructure for Global IT Training, replacing Mailchimp with a scalable AWS-based Sendy + Amazon SES/SNS solution capable of sending over 50,000 authenticated messages per day. The system featured SPF, DKIM, and DMARC authentication, automated bounce and suppression management, and integration with HubSpot CRM for full lifecycle automation—dramatically reducing SaaS costs while improving deliverability, control, and reporting. Validated through ZeroBounce and BrightVerify, and later upgraded with Everest by Validity for deliverability monitoring and engagement analytics, the platform powered all GITT campaigns through branded, responsive HTML templates and automated CRM workflows.

Scope & Deliverables:

• Client: Teknologix / Global IT Training
• Scope: Self-hosted enterprise email infrastructure with AWS SES/SNS integration and HubSpot CRM lifecycle automation.
