Smartlead is cold email built with agencies in mind. The features that set it apart — white-label client dashboards, a unified inbox across all your mailboxes, and generous warmup — are exactly what you need when you’re running outbound for several clients at once.
What Smartlead does
You run campaigns across unlimited warmed mailboxes, manage every reply from one master inbox, and hand clients their own white-labeled view. API access makes it a comfortable backbone for agencies that automate their delivery.
Pricing
Smartlead starts at $39/month on the Base plan (2,000 contacts, 6,000 sends), with Pro at $94/month unlocking API access, white-labeling (one client free, $29/month each after), and 15× the sending capacity — verified July 2026. Unlimited Smart ($174) and Unlimited Prime ($379) raise limits further, though sending volume stays tiered even on “unlimited” plans. Annual billing saves about 17%. Budget for mailboxes and domains on top, as with any cold-email tool.
Who it’s for
Smartlead is the natural choice for agencies and operators who need white-label delivery and multi-client management. A solo sender running one brand won’t use half its strengths and might prefer a simpler interface.
