Stamina.io is an all-in-one outbound sales platform that combines B2B data, AI personalization, multi-channel campaigns, a built-in dialer, and workflow automation with a dedicated GTM engineer — purpose-built for teams that need pipeline, not just activity.
What is Stamina.io?
Stamina.io is a B2B outbound sales platform that unifies prospecting, personalization, sequencing, calling, and reporting in one workspace. It takes prospect lists and account signals as input and produces booked meetings and closed pipeline as output. The platform runs on the web and includes a dedicated Growth Strategist (GTM engineer) who configures campaigns, optimizes deliverability, and tunes performance. Stamina.io is developed and operated by Stamina.
Key Features
- B2B Data (500M+ contacts) — 65+ filters across job title, seniority, department, company size, revenue, industry, location, and tech stack. Verified work emails with catch-all domain flags. One-click push to campaigns — no CSV exports.
- AI Personalization (6 types) — Zero-setup AI-generated email and SMS copy tailored to each prospect’s profile. No 47-step table configurations or waterfall logic.
- Multi-step email & SMS campaigns — Native sequencing with A/B testing, timing, and inbox rotation. Campaigns include deliverability tooling (domain health, warmup, inbox rotation).
- Built-in power dialer — Queue-based calling with auto-logging and disposition tracking. Reps can call directly from the platform without switching tabs.
- Workflow automation — Trigger-based actions across channels (email, SMS, calls) and pipeline stages. Automate follow-ups, lead enrichment, and signal-based prioritization.
- AI reply classification — Reads inbound emails, classifies intent (interested, not interested, out of office, wrong person), and routes or responds automatically.
- Dedicated GTM engineer — Every client gets a real human who handles strategy architecture (ICP definition, list building, messaging), campaign configuration, deliverability optimization, and ongoing performance tuning.
Who is it for?
- SDR teams — High-volume prospecting with queue-based calling, automated sequences, and AI-sorted replies so reps spend time selling, not sorting inboxes.
- GTM leaders — Build and scale outbound motions from a single platform instead of stitching together five tools; full-funnel analytics from first touch to meeting booked.
- Revenue teams — Unified data across sales, marketing, and RevOps with clear attribution; everyone knows who’s responsible for what.
- Agencies — Run outbound for multiple clients using multi-tenant workspaces, white-label options, and campaign-level reporting per client.
What can you do with Stamina.io?
- Outbound prospecting at scale: Use the Prospector module with 65+ firmographic filters to build targeted lead lists, then push directly to campaigns with one click.
- Multi-channel campaign sequencing: Create multi-step email and SMS sequences with A/B testing, timing, and automated follow-ups powered by AI reply classification.
- Deliverability management: Monitor domain health, warm up inboxes, and rotate sending accounts to maintain high inbox placement rates — all native to the platform.
- Personalize at zero setup: Generate AI-written email copy tailored to each prospect using six personalization types (job title, company, pain points, etc.) without complex table configurations.
How does Stamina.io work?
Stamina.io follows a four-stage workflow: Data (prospect search & enrichment) → Personalization (AI copy generation) → Action (campaigns, dialer, workflows) → Reporting (pipeline attribution). Every client is paired with a dedicated GTM engineer who architects the strategy, configures campaigns, and optimizes sequences over time. The platform manages sending infrastructure natively — provisioned inboxes, domain warmup, and rotation are all included.
