Smartlead is cold email software for outbound sales. It lets you connect unlimited mailboxes, warms them up automatically with simulated opens and replies, and handles DNS, SPF, DKIM and DMARC setup and sender rotation. Dedicated-tenant infrastructure and real-time monitoring of bounces and spam flags aim to keep messages in the primary inbox. Plans run $39 per month for Base, $94 for Pro, $174 for Smart and $379 for Prime on monthly billing, with yearly billing about 17% cheaper.
It is aimed at sales teams, lead-generation agencies, SDR groups and founders who run outbound at volume and manage many clients or domains. Agencies benefit from client workspaces and a shared Master Inbox, while revenue teams use the CRM, dialer and AI agents to cover the cycle from prospecting to closing. Higher tiers add private infrastructure, API and webhooks, and dedicated support options for larger operations.
Typical use includes building a verified prospect list, launching multi-step sequences across many mailboxes, and sorting replies by intent in one inbox so hot leads get follow-ups quickly. Teams can buy Google or Outlook mailboxes and domains through SmartSenders, then let the warm-up engine prepare them before sending. AI agents can research leads, write personalized emails, update the CRM and classify replies, while the dialer adds calls with parallel dialing and local-presence numbers. Agencies often run campaigns for several clients at once from separate workspaces, tracking deals on a drag-and-drop board that syncs with outreach activity.
