How we review tools
We look at the job a tool does, how it connects to a sales process, its costs and its limits. “Used by H2” means it is part of our work. “Researched by H2” means our notes are based on research rather than hands-on use. Each tool has a dated review with the full context.
“Best” means best for the job described. Check a small sample from your own market before committing to a larger plan. Our current focus is B2B outbound; teams running paid advertising or product-led growth will need a different mix.
H2 is a Clay Solutions Partner and a Smartlead Certified Partner. Each tool shows when its pricing and notes were reviewed. Check the linked vendor pages for current billing terms.
