What is Stamina

Stamina is an outbound sales platform that handles the full lifecycle of cold email outreach — from infrastructure and lead discovery to AI personalization, campaign execution, and reply management.

What Stamina does

• Email infrastructure — Stamina provisions outreach domains and inboxes, configures DNS authentication (SPF, DKIM, DMARC), and runs inbox warmup automatically. You don't need to manage this yourself.

• Lead Finder — Search and filter 100M+ verified contacts using 65+ filters across company size, industry, job title, location, funding stage, tech stack, and more.

• AI personalization — Stamina enriches leads and generates personalized email copy using signals like recent funding, ICP fit, active job posts, and case studies.

• Campaigns — Build multi-step email sequences with delays, A/B testing, dynamic variables, and sending schedules. Campaigns run automatically against your schedule.

• Unibox — All replies from all sending accounts appear in one unified inbox. Manage conversations, update lead status, add labels, set reminders, and reply without switching tabs.

How it fits together

Stamina is designed so every part feeds the next. You set up infrastructure once, then use it across all campaigns. Leads flow from targeting into enrichment, from enrichment into sequences, and from sequences into Unibox — where your team takes over for the human conversation.

Who it's built for

Stamina is built for sales teams and agencies running high-volume cold outreach who need reliable deliverability, AI-assisted personalization, and a unified workspace to manage replies at scale.
