Microsoft 365

Connect your Microsoft 365 or Outlook account directly to Prosyo with secure, one-click OAuth to turn your enterprise email infrastructure into an automated outbound engine. Instead of relying on disconnected mail merges or manual inbox management, Prosyo natively combines your Outlook cold email campaigns with automated LinkedIn outreach, putting your entire B2B sales pipeline under one roof.

Build dynamic, multichannel sequences that naturally follow prospects across platforms. Seamlessly pair scheduled Outlook emails with automated LinkedIn profile visits, connection requests, and follow-up messages. If a prospect responds on LinkedIn, Prosyo instantly pauses the automated email cadence, ensuring your outreach remains highly relevant and preventing embarrassing double-touches.

Protect your corporate sender reputation with built-in Microsoft 365 deliverability guardrails. Prosyo strictly adheres to Outlook’s sending protocols by implementing randomized dispatch delays, human-like activity pacing, and strict daily volume limits. This algorithmic pacing keeps your domains off blacklists and ensures your personalized pitches consistently land in the primary inbox rather than Microsoft’s junk folder.

Manage every reply without constantly refreshing your Outlook client. Prosyo routes all incoming Microsoft 365 email responses and LinkedIn direct messages into a single, synchronized unified inbox. Built-in intent detection automatically categorizes auto-replies, bouncebacks, and positive buying signals, allowing your sales reps to prioritize and respond to the warmest leads immediately.

Eliminate manual data entry and keep your tech stack aligned. Every Outlook email sent, opened, and replied to is automatically logged against the correct prospect profile and synced bi-directionally with your HubSpot CRM timeline. This ensures total visibility for your sales managers while freeing up your reps to focus on closing deals instead of updating spreadsheets.
