Best for agencies with unlimited mailboxes
Try SmartleadSmartlead Basic at $39 monthly covers unlimited email accounts (sender mailboxes), 6,000 emails per month, unified inbox, and email warmup. The unlimited-mailbox pricing model is the differentiator: agencies running outbound for multiple clients hit Lemlist's per-user pricing wall fast, while Smartlead's per-account-monthly model scales linearly with sending volume rather than user count. Pro at $94 covers 30K emails monthly and sub-sequences; Custom at $174+ covers unlimited emails. For sales teams running 10+ sender mailboxes per rep (the deliverability-spreading pattern), Smartlead is the right shape; Lemlist would charge per user.
