Everything
You Need for
Professional Outreach

A comprehensive suite of tools built directly into your Outlook environment.

Local-First Security

Your data stays within your trusted infrastructure. Our Private engine offers 100% local processing via Microsoft VSTO, while our Modern version utilizes your existing Microsoft 365 security tokens for zero third-party cloud storage.

Individualized Attachments

Deliver more than just text. Securely attach unique invoices, legal contracts, or reports to each recipient. FlowDrafts programmatically maps your local files to your Excel contact data automatically in one click.

Relationship-Aware Logic

Our smart engine handles the nuances of outreach. It automatically switches between individual names and collective greetings based on your relationship thresholds. Explore industry-specific workflows.

Native Scale & Speed

Send thousands of emails daily through your own server. By utilizing your local Outlook instance, you bypass the artificial limits of web-based marketing platforms.

Team-Ready Delegation

Prepare campaigns and delegate the execution. Export entire setups as secure, portable ZIP packages for your team to run locally.

Solutions

Built for High-Stakes Communication

FlowDrafts adapts to the specific compliance and personalization needs of your industry.

M&A

M&A & Deal Flow

Accelerate sell-side outreach. Securely distribute project teasers and NDAs to buyer pools in minutes, not hours, with full localized audit trails.

Security

Privileged Communication

Manage sensitive legal notices, NDAs, and private wealth reporting with 100% data sovereignty. Ensure PII never leaves your secure workstation.

Compliance

Life Sciences & CRO

Automate the distribution of trial protocols and ethics approvals to investigator sites. Maintain strict HIPAA/GDPR compliance with local-first processing.

Risk

Risk & Enterprise Ops

Scale individual policy renewals, custom invoices, or sensitive internal comms. Eliminate "Attachment Drift" and cloud-relay exposure across the organization.
