Beyond the scores
What separates these tools for an agency is how each plan handles clients: a white-label option, seats or sub-accounts, and sending limits. The sections below read each in the plans' own listings, then the agency reviews.
Skylead and CoPilot AI list white-label options on quote-priced plans
Skylead's Agency plan lists a white-label solution option, a Unibox for all client conversations and a trainable AI SDR to deploy across clients, and its Annual plan lists a white label option, read on Sep 27, 2026.

HighLevel counts sub-accounts, while Skylead and Valley count seats
HighLevel, an all-in-one platform with CRM, funnels and automation, counts clients in sub-accounts. Its Starter plan is $97 a month, billed monthly, for 3 sub-accounts and unlimited users, and its Unlimited plan is $297 a month, billed monthly, for unlimited sub-accounts; Agency Pro adds SaaS Mode and automated sub-account creation.

Close has 4 of its 37, against 18 from teams. Woodpecker has 3 of its 29, against 8 from teams, and Clay has 2 of its 28, against 12 from teams.
These tagged reviews run up to August 2026 for Woodpecker and up to September 2026 for the other four. Each score in the table rests on all of a tool's tagged reviews, so agency use is one part of it.
Before you choose
