AiSDR vs Smartlead
By Frederik S. Christiansen · Updated 2026-07-05
AiSDR: AI SDR agent that finds prospects from buying signals, runs personalized email and LinkedIn outreach, and books meetings; plans from $250/month.
Smartlead: Cold email outreach platform with unlimited sender mailboxes, automated warmup, and agency whitelabel features, priced by monthly send volume.
Smartlead sells cold-email infrastructure — unlimited sender mailboxes, warm-up, white-label options, and an API — on cheap self-serve tiers, but includes no lead database or autonomous agent; AiSDR instead supplies AI-researched contacts, writes the outreach, and handles replies, at a substantially higher flat monthly price.
An autonomous AI SDR service rather than a campaign tool: AiSDR writes and sends outreach for you and is billed quarterly above its entry tier, with its Explore plan at $900/month covering 800 AI-researched contacts monthly, versus Smartlead's self-serve tiers from $39/month where your own team builds and operates the campaigns.
