Alexa Dotson is a fraud consultant at SEON, where she has worked since April 2026. Before that she spent just over two years at Brevo, first as a Deliverability and Compliance Engineer and then as an Anti-Fraud Data Analyst. She came to Brevo from Mailgun, where she spent four and a half years, moving from application administration into deliverability and compliance work. There she monitored the sending platform for spam, policy violations, and compromised accounts, and built automation to disable abusive senders. She also wrote the internal procedures Mailgun's support team used to help customers whose API keys had been exposed through developer framework vulnerabilities. Her expertise covers SPF, DKIM, and DMARC, payment fraud on Stripe, and the tactics bad actors use to find exposed credentials. She started her career with five and a half years in complex billing at USAA in San Antonio, Texas.
