Smartlead

Smartlead is a cold-email outreach platform focused on deliverability, offering unlimited connected mailboxes, automated warm-up, a master inbox, and a built-in lead database. It is aimed at sales teams, agencies, and founders running cold email at scale who want to manage many sending accounts and replies in one place. Native automation is email-centric; LinkedIn and other channels appear in the master inbox but multichannel sending typically requires pairing with separate tools.
