The people behind Mailsource
We started Mailsource because outreach had stopped feeling personal — so we built a team to fix that
CEO and Founder
Zach founded Mailsource after a career spanning underwriting, broking and B2B sales — most recently as an Account Executive at Revolut. Having worked both sides of the sales conversation, Zach built Mailsource around a simple belief: outreach lands best when it feels personal, not mass-produced. He leads the company’s vision, strategy and client relationships.
COO and Founder
Matthew co-founded Mailsource and runs the day-to-day operations that keep every campaign on track — from planning and production through to delivery. He focuses on building the systems, processes and team that let Mailsource scale personal outreach without losing the personal touch.
Head of Legal
Ning is Head of Legal at Mailsource, combining a background in intellectual property and commercial law with a strong interest in how businesses build meaningful relationships. With an LL.M. in Intellectual Property Law from Queen Mary University of London, Ning brings a legal and strategic perspective to Mailsource, helping businesses connect with the right prospects in a way that feels personal, thoughtful and genuinely human.
