Handling Website Leads Without Leaving Umbraco: A Look at umContactManager

For many Umbraco sites, a contact form is where lead handling starts and where things begin to go wrong. Submissions go to one inbox, replies are sent from another, spam piles up, and important leads are copied into a CRM by hand. umContactManager was built to bring all of this into the CMS itself.

Why lead handling breaks down in a CMS

Website inquiries rarely come from a single source. Built-in forms, custom frontends, landing pages, and remote sites all send data in different formats and with different authentication. Public forms also attract bots and floods of junk submissions. In addition, outbound email is usually disconnected from the submission that triggered it. As a result, editors have no single place to see a lead's full history.

What the plugin does 

umContactManager, developed by OSKI Solutions, adds a dedicated Contacts section to the Umbraco backoffice. It brings together form submissions, inbound email, spam filtering, outbound communication, and notifications. The goal is to make contact handling simpler and more automated, so teams reply faster, spend less time on manual CRM work, and scale contact operations without leaving Umbraco.

One pipeline for every lead source

Every lead source goes through one shared submission pipeline with three channels:

• the built-in Contact Manager Form

• custom forms on the same site

• an external JSON API

All channels share one field catalog, the same security rules, and API keys. This makes the plugin suitable for both single-site and multi-site setups, including headless clients.

Spam stopped at the entrance

Protection works in several layers:

• rate limiting

• honeypot soft-accept

• CAPTCHA hooks

• payload size limits

• allowed origins

• automatic spam marking once a threshold is reached

All channels share one field catalog, the same security rules, and API keys. This makes the plugin suitable for both single-site and multi-site setups, including headless clients.

Email that keeps its context

• Outbound: sent through SMTP or Postmark, using tokenized notification and thank-you templates.

• Replies: written directly from the contact's workspace.

• Attachments: stored locally or in Amazon S3.

• Inbound: received through Postmark webhooks.

• Email History: each message shows its status (Queued, Sent, Delivered, Bounced, Opened, or Spam complaint).

A CRM view inside the CMS

The Contacts section separates Incoming, Archived, and Spam, and includes:

• search, filters, and bulk actions

• activity badges

• GeoIP lookup

• a detailed workspace for each contact with its submission and email history

Event-driven notifications, including Telegram, alert the team about new submissions, customer replies, and direct email leads.

Optional AI assistance

• Reply drafting: done with OpenAI or Claude, using configurable instructions.

• Lead intelligence: adds risk scoring, company and person context, and auto-research. It can also automatically archive low-quality leads. email history

Providers you can swap

AI, email transport, attachment storage, and notifications are built as interchangeable providers. Projects can pick services based on cost, operational preferences, or compliance requirements without touching the core.
