What We Build Into Your HubSpot Integration
HubSpot Contact Lookup in Outlook
Open any email and see the sender's HubSpot contact record, company, deal stage, and recent activity directly in the Outlook task pane, with no browser tab needed.
One-Click Email Logging
Log Outlook emails to HubSpot contact or deal records with a single click. No copy-pasting, no manual CRM entry after every sales conversation.
Deal Stage Visibility
See open deals and their current stage for any contact directly inside Outlook so your team has context before every reply.
Live Pipeline Data in Excel
Pull HubSpot deals, contacts, and pipeline metrics into Excel via API so revenue ops teams work with live data instead of weekly CSV exports.
Two-Way Contact Sync
Update HubSpot contact fields from Excel and push changes back to HubSpot automatically, keeping your CRM current without opening it.
HubSpot OAuth 2.0 Auth
We implement HubSpot's official OAuth 2.0 flow so users authenticate securely with their HubSpot credentials and the add-in handles token refresh automatically.
How the Integration Project Works
- 1
HubSpot API Review
We review your HubSpot portal, confirm API access, and map which objects your team needs inside Outlook or Excel, such as contacts, deals, companies, activities, or custom properties.
- 2
OAuth Setup & Connection
We implement HubSpot OAuth 2.0 and establish a stable API connection tested against your live HubSpot portal before any add-in development starts.
- 3
Field Mapping
We map HubSpot property names and data structures to what displays in Outlook or Excel, surfacing the fields your sales team actually uses rather than every property in your portal.
- 4
Add-in Build & Testing
We build the Outlook contextual add-in or Excel task pane, test email logging against real contacts, and confirm deal sync works across your pipeline stages.
- 5
Deployment & Handover
We deploy via Microsoft Admin Center, confirm the add-in works in Outlook web and desktop, and hand over documentation your HubSpot admin can reference.

Featured Solutions & Interfaces
Two tools, two versions of the truth
Which stage was the deal actually in? At a 60-person logistics software company, the answer depended on whether you asked HubSpot or the sales team's inboxes, and the revenue operations manager was tired of refereeing. Marketing ran lifecycle stages in HubSpot; sales lived in Outlook and updated deals in batches on Friday afternoons, so mid-week forecasts were fiction.
We built two connected pieces. In Outlook, a panel shows the sender's record and lets reps advance a deal stage or log a thread as they read, which moved updates from weekly to continuous. In Excel, the rev-ops manager pulls live pipeline snapshots against her own cohort formulas instead of exporting CSVs every Monday. Forecast reviews now open with one number on the screen. The rep who resisted longest was converted by a small thing: the panel pre-fills the required fields he used to be nagged about.
Do you even need a custom HubSpot build?
Often not. HubSpot's own Outlook extension handles basic logging and tracking, and on lower tiers it is the sensible default. Custom work makes sense once your process outgrows it: required properties by pipeline, custom objects, quote data landing in Excel, or logging rules the stock tool cannot express. If Outlook is only half the story and Salesforce or Dynamics runs elsewhere in the group, our wider CRM integration work covers the mixed estate.
HubSpot Integration: Common Questions
Yes. We build Outlook contextual add-ins that detect the sender's email, query HubSpot via API, and display the matching contact record, deal stage, and recent activity in the Outlook task pane.
