Founder, MailFirst · Smartlead Expert

“WarmInboxes gives us the deliverability foundation we need to consistently land in the primary inbox and book meetings at scale”

Phil Sergenti, Founder of MailFirst, shares how Warm Inboxes provides the infrastructure foundation that powers his cold email campaigns for VC-backed B2B companies.

Phil Sergenti founded MailFirst, a cold email agency serving VC-backed B2B companies, and he is a certified Smartlead expert. His campaigns run on WarmInboxes infrastructure: prewarmed inboxes for immediate sending and fresh inboxes on dedicated domains for scale.

When your clients are venture-backed and pipeline targets are contractual, the deliverability foundation matters more than any copy tweak. That foundation, prewarmed and fresh domains with verified authentication, is exactly what Phil describes in the video.
