# Smartlead vs Instantly

Two cold email platforms that both sell unlimited mailboxes and warmup under a flat plan. **Smartlead** wins on per-email economics at scale and agency white-label workspaces; **Instantly** wins on polish and a 450M lead database bundled in. Both demand someone own deliverability daily.

## The decision

Choose Smartlead if you send at volume across many domains, want the cheapest per-email math, and run an agency with client workspaces. Choose Instantly if you want a more polished UI, a bundled lead database, and can pay more per send for it.
