The four operating models

Which agencies run which channels

1. Email and LinkedIn, done for you

Best when your buyers read email and LinkedIn and you want one team to own the whole thing: lists, copy, sending domains, replies and booking.

• Terms: a 3-month minimum, paid monthly, then month-to-month. Live in 14 days.
• Replies: a reply agent answers interested leads in under 2 minutes and books them onto your calendar. A client portal with full data export.
