Four separate tools can each do their own job. None of them can do this.
When Outreach classifies a reply as positive, the deal is created, the email thread is attached to it, and the inbound reply is logged as activity — as one step, not three.
An outbound send from a campaign logs the activity against the lead or deal and can move it to the next stage.
Suppression is derived across the suite. If someone has an open support ticket, or has unsubscribed, or their address has hard-bounced, Outreach will not mail them.
Promotion from the prospect database into Contacts is one action, and an entire list can be exported into a campaign.
Mail attaches to a person, organisation, lead or deal — explicitly when you say so, and automatically when the address is already known.
Every pipeline, every thread, every ticket.
