Four packages are offered, Amplify Essentials (10,000 AI credits), Amplify Core (25,000), Amplify Plus (50,000) and Amplify Pro (100,000), ranging from conversation intelligence and coaching to pipeline management and forecasting. All are quote-only, and additional credit packs can be purchased.

Salesloft is a sales engagement platform providing cadences, conversation intelligence and deal management. It has merged with Clari, the revenue forecasting company, and the two now operate as one company under the Salesloft name; Clari Forecast continues as a product within the combined platform alongside Salesloft's cadence, analytics and pipeline-inspection tools. Salesloft does not publish prices: its pricing address leads to a sales-contact page. Like Outreach, it is aimed at mid-sized and large revenue teams that want sequencing, call analysis and forecasting from one vendor, and is rarely used for high-volume cold email to purchased lists, for which lighter tools are more common.
