Public information verified on Oct 3, 2026. It may change. Prices are not compared: they change often, so check each vendor's own site.
Channels
Outbly
Email sent from your own Gmail, Outlook or SMTP mailboxes, SMS through Twilio, call tasks with a script, and LinkedIn reminders that you carry out yourself. There is no connection to your LinkedIn account and nothing is sent automatically on LinkedIn.
Smartlead
Cold email is the core. Smartlead's site also mentions power dialing with AI multichannel calls, and states that there is no limit on the number of channels you can use.
Lead data
Outbly
CSV and Excel import with column mapping and deduplication, plus search through third-party data providers (such as Apollo, Prospeo, Clay or Apify) when the platform administrator has connected them. Email verification is available.
Smartlead
Lead verification and discovery through a product called SmartProspect.
Deliverability and warm-up
Outbly
SPF, DKIM and DMARC status for each sending domain with fix instructions, daily limits per mailbox, send windows and automatic pause on bounces. Warm-up is a gradual volume increase, on by default and never above your own limit. Exchanges between your own mailboxes are optional, at your own risk, and may go against provider rules.
Smartlead
Unlimited mailboxes, built-in setup and warm-up, dedicated infrastructure with private IPs, bounce and spam monitoring, and an email placement data feature. Its warm-up is described as gradual volume ramps combined with positive interactions.
AI
Outbly
AI company research that keeps source URLs and marks facts as verified or inferred. Personalized emails may only reference those facts, and AI drafts wait for your approval by default. AI operations use monthly credits.
Smartlead
An AI cold email assistant and AI agents described as a go-to-market workforce.
Inbox and CRM
Outbly
One inbox for email replies, with automatic classification (interested, question, not now, unsubscribe), a suggested answer you can edit, and a built-in CRM with pipeline, opportunities, meetings and tasks. A booked meeting stops the sequence.
Smartlead
A unified master inbox described as covering the entire deal flow.
Integrations and compliance
Outbly
A public API with an OpenAPI description and webhooks, and CRM synchronisation (for example HubSpot and Pipedrive). A suppression list and a one-click unsubscribe header are applied before every send.
Smartlead
APIs, webhooks, CRM integrations (HubSpot, Salesforce and Pipedrive are mentioned), connections through Zapier, Make and n8n, and white-label capabilities.
What Smartlead does well
- Infrastructure options such as dedicated IPs and unlimited mailboxes, aimed at teams that send from many mailboxes.
- Broad integration surface: webhooks, automation platforms and several CRMs.
- White-label capabilities, useful for agencies.
Smartlead may suit you if
You run email outreach at scale across many mailboxes and want dedicated infrastructure, webhooks and automation connections.
Outbly may suit you if
You want sourced AI research with human approval of drafts, SMS, call and manual LinkedIn steps in the same sequence, and a built-in CRM, with a gradual volume increase on by default.
