Smartlead's add-ons raise the total: SmartDelivery placement tests from $49/month, SmartServers at $39/server/month and verified emails at $59/month on Base and Pro.

- AI Sales Agent and AI Reply Agent automate campaign creation and inbox replies

- Advanced deliverability infrastructure (SISR dedicated IP system) is only available on the $555+/month Agency bundle
- Enterprise-level volume and account management require a custom sales call rather than self-serve checkout
Smartlead
Pros
- Unlimited mailboxes and unlimited warmup on all four plans, so adding inboxes does not raise the subscription.
- Automatic sender rotation spreads each campaign across connected mailboxes to protect individual sender reputation.
- Master inbox auto-categorizes replies from every mailbox and client and syncs them to HubSpot, Salesforce or Pipedrive.

Cons
- The Base plan excludes the API, webhooks and CRM that agencies usually need.
- Add-ons stack up: SmartDelivery placement tests start at $49/month, dedicated SmartServers cost $39/server/month and verified leads cost $59/month on Base and Pro.
- Support is AI-first: ticketed human support was replaced by SmartAssistant, with staff stepping in by phone for unresolved issues.
- The iOS app rates 2.1/5 from 9 App Store ratings, so day-to-day work stays on the web app.
