OutboundSync
Cold outbound and OutboundSync never truly sync, so hot replies miss the pipeline. Master Inbox pushes every reply into OutboundSync automatically.
How OutboundSync works with Master Inbox
OutboundSync is the managed integration between sales engagement tools and the CRM: every email sent, opened, clicked and replied to lands in HubSpot, Salesforce, Close or Attio as contact, company and timeline records, matched and deduplicated, with campaign attribution intact. Master Inbox is a direct integration in OutboundSync (beta, one-way into the CRM): inbound and outbound replies, the AI intent and sentiment on each one and thread metadata land as contact properties and events, so the replies only Master Inbox catches (forwards, CC replies, new addresses, late replies) reach the same record. Tools without their own OutboundSync connector, such as Lemlist, Expandi, Prospeo, FindyMail, BetterContact, Icypeas and Salesflow, reach the CRM through Master Inbox. Use Master Inbox for the replies and OutboundSync for the system of record.
What you can do
- Sends, opens, clicks and bounces from Smartlead, Instantly, EmailBison and the rest logged as CRM activities
- Master Inbox labels and the replies the sequencer never saw, written to the right HubSpot or Salesforce record
- Salesforce, Close, Pipedrive and HighLevel sync for Master Inbox customers today, with campaign attribution
- Lemlist, Expandi, Prospeo, FindyMail, BetterContact, Icypeas and Salesflow into the CRM through Master Inbox
- Several sequencers into one CRM without duplicate contacts
Why it matters for outbound revenue teams
Master Inbox answers who replied and what they meant. OutboundSync answers what was sent, from which campaign, and what happened next, inside the CRM. Teams that report on outbound in HubSpot or Salesforce run both.
“I’m an OutboundSync customer, so I know you guys, I know Harris.”
OutboundSync + Master Inbox FAQs
Do I need OutboundSync to use Master Inbox with HubSpot?
No. The Master Inbox HubSpot Suite syncs conversations and labels to the contact record and lets reps reply from HubSpot. Add OutboundSync when you want sends, opens, clicks and campaign attribution in HubSpot reporting, or when several sequencers feed one CRM.
How do the two connect?
Connect your sequencers to OutboundSync as usual, then connect Master Inbox as a direct integration in OutboundSync (beta, one-way from Master Inbox into the CRM) and choose which labels and AI fields become CRM properties. Onboarding sets it up with you on the first call.
Which CRMs does the Master Inbox integration in OutboundSync support?
HubSpot, Salesforce, Close, Attio, Pipedrive and HighLevel, per OutboundSync's integration page.
Will I get duplicate activities?
Not if one system owns each activity type. OutboundSync logs sends, opens, clicks and the replies the sequencer saw; Master Inbox adds only the replies and labels it catches.
