What is Stamina

Last updated: July 15, 2026

Stamina is an outbound sales platform that handles the full lifecycle of cold email outreach. This includes infrastructure setup, lead discovery, AI-assisted personalization, campaign execution, and reply management, all from a single workspace.

What Stamina does

Email infrastructure. Stamina provisions outreach domains and inboxes, configures DNS authentication (SPF, DKIM, and DMARC), and runs inbox warmup automatically. You can set this up yourself in a few clicks under Settings > Inboxes & Domains, or let Stamina handle it end to end with Done-for-you email setup. No manual back-and-forth is required either way.

Prospector. Search and filter verified contacts across company size, industry, job title, location, funding stage, technology stack, and more. Use the People filters to target individuals, the Company filters to target accounts, or skip filters entirely and describe who you're looking for in plain language with Use AI to find leads. Stamina's AI will search on your behalf and return a matching list.

Personalization. Once you have a lead list, this is where you enrich it and prepare it for outreach. Turn on Enrichment to fill in fields like role, mobile number, work email, location, and company details. Turn on Signals to flag leads with recent funding, new job postings, technology changes, or news events, so you can reference them in your outreach. Or use the Use AI panel to generate custom columns and personalized copy from a plain-language prompt, choosing the underlying AI model and reasoning depth yourself.

Sequences. Build multi-step email campaigns with subject-line and body variants for A/B testing, dynamic variables such as {{firstName}} and {{companyName}}, custom sending schedules, and daily sending limits. Once launched, a sequence runs automatically according to the schedule and rules you set.

Inbox. Every reply from every sending account you own lands in one unified inbox. From here you can manage conversations, track campaign opportunities, and respond, all without switching between accounts or tabs.

How it fits together

Every part of Stamina is designed to feed into the next. You set up your infrastructure once, and it's available across all future campaigns. Leads flow from Prospector into Personalization for enrichment, from Personalization into a Sequence for outreach, and from Sequences into your Inbox, where your team takes over for the human part of the conversation.

Working with a team

If you're working with a team, Stamina supports role-based access so different people can have different levels of visibility and control.

There are four built-in roles: viewer, editor, admin, and creator, each with a different set of permissions. Admins have full access across the workspace, including billing, inbox and domain setup, and user management.

Other roles are more limited by default, and specific resources like Personalization lists or Sequences can be shared with individual collaborators so they only see what's relevant to them.

See Inviting your team and understanding roles in the 📄 Quick-start guide for a full walkthrough.
