How Cornerstone Commercial Realty Automated 70% of Tenant Inquiries with AI Email Drafting
Challenge
Cornerstone Commercial Realty is a mid-sized commercial real estate agency based in Dallas, Texas, managing a portfolio of over 80 properties across office spaces, retail units, and mixed-use developments. With a leasing team of eleven agents and a property management coordinator handling day-to-day operations, the firm had built a strong regional reputation over twelve years in business.
But by late 2025, their inbox had become a serious operational bottleneck.
Prospective tenants – businesses looking for office space, retail units, or flexible commercial leases - sent the same questions constantly. What's the square footage? Is parking included? Are utilities covered? What's the lease term? Can we schedule a viewing? Is the space still available?
Every agent was answering these questions individually, manually, from scratch, multiple times a day. The leasing coordinator, Rachel Osman, estimated the team collectively spent between three and four hours daily just answering inbound inquiries – the majority of which were identical questions about the same properties.
The real cost wasn't just time. It was speed. In commercial real estate, a business looking for space is often evaluating multiple properties simultaneously. The agency that responds first and responds well – wins the viewing. Cornerstone was losing ground to faster competitors simply because their agents were buried in their inboxes when they should have been out showing properties.
"We had agents replying to the same question about parking on three different threads on the same day," said Marcus Webb, Cornerstone's Managing Director. "It wasn't sustainable and it wasn't a good use of their time."
Approach
Cornerstone connected their primary leasing inbox and each agent's individual Gmail account to InboxPilot in a single afternoon. The setup took less than two hours across the whole team.
The first step was building out the Knowledge Center. The team uploaded:
- A master property information sheet covering all 80+ properties — square footage, lease terms, pricing ranges, parking availability, utilities, pet policies, and availability status
- A FAQ document covering the 30 most common tenant questions with Cornerstone's standard answers
- Email templates they had been using manually for viewing confirmations, pricing inquiries, and application instructions
- Their standard lease term explanations and move-in process overview
Within 48 hours the AI had processed the knowledge base and was generating drafts that accurately reflected Cornerstone's property details and communication style.
They set InboxPilot to draft mode rather than auto-send — agents wanted to review replies before they went out, particularly for complex inquiries or negotiations. Each agent would open their inbox in the morning to find drafts already waiting for the emails that had arrived overnight and through the early morning. Most required only minor edits — adjusting a specific detail or adding a personal note — before hitting send.
For the leasing coordinator's shared inbox, where the most repetitive high-volume inquiries landed, they enabled auto-reply for a defined category of standard questions — availability checks, parking questions, utilities queries — while keeping draft mode on for anything more complex.
They also configured InboxPilot's AI labeling to categorize every incoming email:
- New inquiry — first contact from a prospective tenant
- Viewing request — scheduling and confirmation emails
- Lease question — questions about terms, conditions, or the application process
- Existing tenant — correspondence from current tenants
- Maintenance — maintenance requests and follow-ups
- Marketing — vendor outreach and promotional emails
- Misc — anything that didn't fit another category
Email actions routed maintenance requests automatically to the property management coordinator and archived marketing emails without anyone touching them.
"Our agents used to start every morning digging through their inbox. Now they start every morning already on top of it."— Marcus Webb, Managing Director, Cornerstone Commercial Realty
Solution
Within five weeks, Cornerstone had replaced their manual inquiry response process with a fully automated drafting and routing system across all eleven agent inboxes and the shared leasing inbox.
What changed:
- Every incoming tenant inquiry had a draft response waiting before the agent opened their inbox
- Standard questions about parking, utilities, square footage, and availability were handled automatically without agent involvement
- New inquiry emails were labeled and surfaced immediately so no prospective tenant was left waiting
- Maintenance requests were automatically routed to the property management coordinator without going through the leasing team at all
- Marketing emails were archived automatically — no agent time wasted
- The leasing coordinator's inbox dropped from 80-100 emails requiring manual responses per week to roughly 25 that needed genuine human attention
- Agents spent significantly more time on viewings, negotiations, and relationship-building — the work that actually closes deals
The knowledge base also solved a consistency problem Cornerstone hadn't fully recognized. Different agents had been giving slightly different answers to the same questions — particularly around lease terms and utility inclusions. With InboxPilot trained on a single source of truth, every response was accurate and consistent regardless of which agent's inbox it came from.
Results
What’s next
With the drafting and labeling system running smoothly across all inboxes, Cornerstone is now expanding their InboxPilot setup to include:
- Auto-reply enabled for a broader set of standard inquiry categories, reducing draft review time further
- A dedicated label and routing rule for lease renewal conversations, flagging them for senior agent attention 90 days before expiration
- Website chatbot integration to capture prospective tenant inquiries directly from their property listings page and route them into the same InboxPilot dashboard
Their next milestone: full AI auto-reply across all standard inquiry categories by Q3 2026, with the goal of freeing each agent from inbox management entirely during property showing hours.
