Cleverly

Model
Hybrid by service line: LinkedIn outreach is sold as a monthly subscription / retainer starting at a published monthly price, while cold email is described by Cleverly as performance-based and pay-per-meeting-ready lead. Engagements are positioned as done-for-you outbound services across LinkedIn, cold email, and cold calling, with custom quoting beyond the published LinkedIn entry point.

$397–$997 / month

Inbox Attack

Model
Hybrid fixed-fee/project pricing plus monthly retainer options, with a la carte service pricing and paid 1:1 sessions. Specifically: one-off system builds and audits sold at flat fees, channel/package builds sold as fixed-price packages, and an ongoing 3-month managed engagement sold as a monthly retainer. Not performance-based; the site explicitly says they turn down commission-based projects and appointment-setting work.
Typical range
$145-$2,650 per fixed-price service or session
