Editorial Face-off
The Case for Instantly
“Instantly is the #1 cold email tool for agencies and founders who need to scale outbound. Unlimited accounts and warmup at $30/mo is unbeatable value. The main limitation is it's email-only — pair with HeyReach for LinkedIn.”
The Case for Mailshake
“Mailshake is the simplest cold email outreach tool on the market. Perfect for small teams and agencies wanting fast, effective outbound without a learning curve. Lacks the depth of larger platforms.”
