Desislava Zhivkova

Desislava (Desi) Zhivkova is Head of Deliverability and Compliance Operations at Omnisend. She leads the team that keeps the platform's sending infrastructure healthy, which means getting more than 2.5 billion emails a month to inboxes at a 99% delivery rate. Desi has spent over 10 years in the email industry and has worked on both sides of it. Before Omnisend, she spent more than 8 years at Mailjet by Sinch on the infrastructure side. For over 5 of those years, she was a Senior Compliance and Deliverability Analyst handling deliverability, anti-abuse, fraud, and compliance cases. Her advice comes from daily, hands-on work with sender reputation, email authentication, and mailbox provider requirements. She writes Omnisend's Help Center deliverability guides, and the Omnisend blog regularly quotes her on spam placement, domain warmup, and Gmail's Gemini changes. In 2026, she spoke at Deliverability Summit in Barcelona about how AI is used in deliverability operations.
