Connect Lemlist with Attio
Lemlist sends. Attio closes. The replies in between get lost.
Master Inbox is the router in the middle
Lemlist pioneered multichannel outreach across email, LinkedIn, and calls with deep personalization. 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 Lemlist, including the forwards and out-of-office Lemlist 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.
