Two connectors are available for LinkedIn outreach:
| Connector | Tool | Cost | Best For |
|---|---|---|---|
HeyReachConnector | HeyReach | $79/mo (up to 50 accounts) | Campaign orchestration, multi-account |
LinkedInOutreachConnector | Linked API | $49/seat/mo | Per-action granular control |
Default recommendation: HeyReach for cost effectiveness at scale.
[!CAUTION] MANDATORY (retro 2026-04-23): Before recommending a platform, ALWAYS check
.envfor which API key is actually configured (HEYREACH_API_KEYvsLINKEDAPI_API_KEY). The user may only have one platform active. Never assume HeyReach — verify first.
