Smartlead is a cold email and sales engagement platform for B2B teams and agencies, differentiating from competitors by providing unlimited email account connections and unlimited AI-powered warmup on every plan. Plans are Basic ($39/month, 2,000 active leads, 6,000 emails/month), Pro ($94/month, 30,000 active leads, 150,000 emails/month, ChatGPT-4 integration, white-label), and Custom ($174/month+, 12M+ leads). All plans include unlimited seats. A 14-day free trial is available. Add-ons include SmartDelivery ($49–$599/month), SmartServers ($39/month for dedicated IPs), and white-label client workspaces ($29/month per additional client). Total deployment cost significantly exceeds base plan pricing for agencies using add-ons. The Basic plan's 2,000 active lead cap constrains high-volume teams who must upgrade to Pro.

| Plan | Model | Usage Limits | Price |
|---|---|---|---|
| Basic | Smartlead AI warmup engine with unlimited mailbox connections and inbox rotation; no ChatGPT-4 email writing integration | 2,000 active leads; 6,000 emails/month; unlimited email accounts; unlimited AI warmup; unlimited seats; API access; no white-label; no ChatGPT-4 integration | $39/mo monthly |

Pro at $94/month with unlimited email accounts, 30,000 active leads, 150,000 monthly emails, ChatGPT-4 email writing, and global blocklist monitoring provides B2B sales teams with the full cold outreach infrastructure at a cost significantly below enterprise alternatives like Outreach ($100+/seat/month) or Salesloft ($125+/seat/month) — with unlimited seats meaning team growth does not compound per-user cost.
Unlimited email accounts on all plans (including Basic $39/month) and white-label client workspaces on Pro ($29/month per additional client beyond the first included) enable agencies managing multiple client sending domains to consolidate all outreach infrastructure under one platform — though white-label add-on costs compound significantly for agencies with 10+ clients.
Basic at $39/month with unlimited email accounts, unlimited warmup, and 6,000 emails/month provides early-stage B2B teams with production-grade cold email infrastructure at startup-level pricing; the 2,000 active lead cap on Basic forces upgrade to Pro ($94/month) once outreach scales beyond the entry volume.
Basic at $39/month with unlimited seats enables solo cold email consultants and freelance SDRs to invite clients or collaborators without per-user fees; API access enables integration into custom outreach stacks; however, the 2,000 lead limit and absence of ChatGPT-4 on Basic restricts AI-assisted personalization to the $94/month Pro tier.
Zapier
used to connect Smartlead campaign events (new reply, bounce, unsubscribe) to CRM updates, Slack notifications, Google Sheets logging, and custom workflow triggers for teams without native Smartlead CRM integration
Apollo.io
used as the lead prospecting and enrichment tool that sources verified prospect contact data for import into Smartlead campaigns, since Smartlead does not include built-in contact enrichment on its base subscription tiers
Consider These Instead
Choose Instantly over Smartlead when a simpler interface with comparable unlimited mailbox infrastructure and lower effective per-lead cost is preferred for individual or small team cold email without white-label or advanced agency multi-client workspaces. Choose Lemlist over Smartlead when personalized image-based emails, LinkedIn multichannel sequences, and a cleaner interface are priorities over Smartlead's deliverability infrastructure depth — accepting Lemlist's per-mailbox pricing at higher volume. Choose Reply.io over Smartlead when a fully integrated sales engagement platform with LinkedIn automation, phone dialing, CRM sync, and contact enrichment in a single subscription is required, accepting Reply.io's higher per-seat pricing versus Smartlead's unlimited seats.
