Routes the reply
ClosesConnect Instantly with Attio
Instantly sends. Attio closes. The replies in between get lost.
Master Inbox is the router in the middle
Instantly sends high-volume cold email with built-in deliverability and a lead database. Attio is a modern, flexible CRM teams build into the exact workflow they want. The gap is the replies: they scatter across mailboxes, and getting them into Attio 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 Instantly, including the forwards and out-of-office Instantly never surfaces, tags it by intent, and syncs the contact, conversation, and stage straight into Attio. Reps work one inbox; Attio fills itself with warm leads.

Instantly + Attio FAQs
How does Master Inbox connect Instantly and Attio?
It reads replies from your Instantly mailboxes, tags them, and syncs the contact, conversation, and stage into Attio, automatically. It's the reply router between the two.
Do reps reply from Instantly or Attio?
Neither. Reps reply from Master Inbox in one place, and the activity is logged to Attio without copy-paste.
Does it catch Instantly replies that never reach Attio today?
Yes. Forwards, out-of-office, and new-address replies Instantly drops are caught and pushed into Attio with context.
Can one inbox manager work replies across all our Instantly accounts?
Yes. Teams consolidate 50 or more Instantly accounts into one queue with shared labels, snooze, and follow-ups, instead of logging in account by account.
If reps work replies here, does our CRM still get the full picture?
Yes. Contacts, threads, and stages sync to your CRM automatically while reps answer from one inbox, so leadership dashboards do not change.
