Master Inbox is the router in the middle

Mixmax is a Gmail-native sales engagement tool: sequences, tracking, and scheduling in the inbox. Salesforce is where enterprise revenue teams report and forecast. The gap is the replies: they scatter across mailboxes, and getting them into Salesforce means a rep copying threads by hand, if they remember at all. Master Inbox is the router in the middle. It catches every reply from Mixmax, including the forwards and out-of-office Mixmax never surfaces, tags it by intent, and syncs the contact, conversation, and stage straight into Salesforce. Reps work one inbox; Salesforce fills itself with warm leads. Today that Salesforce sync runs through webhooks and our OutboundSync partnership, which carries full campaign attribution into the right record; native Salesforce sync is on the roadmap.

What you can do

  • Every Mixmax reply becomes a Salesforce contact with the full thread attached
  • Interested replies mapped to the right Salesforce stage automatically
  • Reply from Master Inbox, logged to Salesforce, with zero double entry
  • Stop Mixmax from emailing prospects already active in Salesforce

How the Mixmax to Salesforce flow gets set up

  1. 1Connect the mailboxes behind MixmaxBulk-import the sending mailboxes your Mixmax campaigns run on. Master Inbox reads the mailbox itself, which is how it catches forwards, out-of-office chains, and new-address replies Mixmax never surfaces.
  2. 2Link your Mixmax workspaceIn Settings, open Integrations and connect Mixmax with your API key. Campaign context now travels with each reply, so you can see which sequence started every conversation.
  3. 3Connect SalesforceIn Settings, open Integrations and connect Salesforce. Contacts, conversations, and reply tags sync automatically from then on.
  4. 4Map labels to Salesforce stagesChoose which reply labels (interested, pricing, referral) create or update Salesforce records and which pipeline stage each one lands in.
  5. 5Go live with white-glove onboardingOnboarding is done with you, not handed off to docs: we wire the Mixmax to Salesforce flow on your real inboxes during the free 7-day POC.

Why it matters for outbound revenue teams

The Mixmax-to-Salesforce handoff is where outbound revenue leaks: a hot reply that never makes Salesforce is a deal you already paid for and lost. With Master Inbox in the middle, every Mixmax reply lands in Salesforce in seconds, with context.

Cold email and CRM, it never fully works together.

Mixmax + Salesforce FAQs

How does Master Inbox connect Mixmax and Salesforce?

It reads replies from your Mixmax mailboxes, tags them, and syncs the contact, conversation, and stage into Salesforce, automatically. It's the reply router between the two.

Do reps reply from Mixmax or Salesforce?

Neither. Reps reply from Master Inbox in one place, and the activity is logged to Salesforce without copy-paste.

Does it catch Mixmax replies that never reach Salesforce today?

Yes. Forwards, out-of-office, and new-address replies Mixmax drops are caught and pushed into Salesforce with context.

Is the Salesforce sync native?

Not yet. Replies, tags, and stages reach Salesforce through webhook sync today, and for attribution-grade syncing we partner with OutboundSync. Native Salesforce is on the roadmap.
