Pricing at a glance

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

Transmission

Model
Custom-quoted B2B agency engagements, most likely a mix of project-based scopes and ongoing retainer work. Public evidence shows Transmission sells broad strategic and execution services (growth consulting, go-to-market, brand strategy, paid media/performance, demand generation, digital optimization, ABM) rather than fixed packages or published plans.
Typical range
$150-$199 / hr
