Email Infrastructure Overhaul for FinTech Enterprise

Description: A leading FinTech enterprise faced critical email deliverability issues that severely limited engagement and conversion. Their existing marketing system lacked proper domain authentication, segmentation logic, and reporting visibility—causing lost revenue and inconsistent inboxing.

I led a complete overhaul of their email infrastructure using SendGrid and Mailtrap. This included designing a multi-domain setup with advanced authentication (SPF, DKIM, DMARC), custom IP warming strategies, deliverability analytics dashboards, and automated campaign segmentation. I also restructured their internal marketing workflow and implemented performance monitoring for reputation management.

Impact: Inbox placement improved from 56% to 98%, bounce rate dropped by 92%, and email CTR grew by 42%. Campaign ROI increased 3.7x within 90 days, and the client’s marketing reliability reached enterprise-grade standards.
