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

INFUSE

Model
Custom-quote demand generation pricing with multiple billing options: CPL (cost per lead) / performance-based for content activation, MQL/SQL delivery, and targeted lead programs; CPM for some program compositions; and fixed-cost engagements for broader demand generation programs. INFUSE also positions some work as always-on programs versus campaign-based initiatives.
Typical range
$50,000-$199,999 per project
