Official FAQ

Will my prospects know the message was automated?: Based on our reply rates, no, and that’s the proof. Messages open on something specific and timely about the prospect, so they read as hand-written. If they read as automated, these reply rates would not be possible.
How quickly will I see results?: Most campaigns are live in about 15 minutes and see first replies within 48 hours. Median lead-to-meeting time across customers is 11 days, and 74% of booked meetings come from people who never replied to the first message.
Is my LinkedIn account safe?: Yes. Outreach runs on vetted sender profiles with human-like pacing, smart daily limits (75 requests and 200 messages per profile per day), and warm-up protocols, so your own account is never the one sending at scale. Across the entire customer base we’ve had 0 account bans to date.
Does it only work on LinkedIn?: No. Sbl.so runs LinkedIn and WhatsApp in a single adaptive journey, switching channels based on how each lead behaves, so follow-up lands where the prospect actually responds.
Do I need Sales Navigator or LinkedIn Premium?: No. Sbl.so works with a standard LinkedIn account. If you have Sales Navigator data, you can import it, but it is not required to start.
What does it integrate with?: Two-way sync with HubSpot, a built-in CRM, a public API, and the Sbl.so MCP server so you can drive campaigns from Claude and your own tooling.
