CRM and PropTech Stack for London Property Marketing

The right CRM and PropTech stack is the difference between a property marketing engine that compounds and a collection of tools nobody actually uses. Most London property firms have invested in software over the years and now run a fragmented stack: a CRM that handles transactions, an email tool that nobody uses, a website with no integration to the CRM, a social media account managed by a junior team member with no connection to the marketing data.

The firms that win operate the stack as a unified system. The leads from every channel flow into one place. The communications happen automatically. The team knows what to do because the system tells them. This post covers the practical stack for a London property firm in 2026: what each tool does, where the integration points are, and which decisions matter.

The five components of the stack

A complete property marketing stack has five core components:

The website and listing management layer. Where properties are displayed and where enquiries are captured. Typically built on a property-specific platform (Reapit, Alto, Dezrez) with portal feeds, or on a custom build with CRM integration.

The CRM. Where leads, contacts, transactions, and communications are stored. The single source of truth for the firm's customer data.

The marketing automation layer. Where nurture sequences, campaigns, and segmented communications run. Either built into the CRM or layered on with a specialist tool.

The analytics and attribution layer. Where channel performance is measured and where leads are tracked through to closed transactions.

The agent productivity layer. Where the negotiator manages their day: call lists, viewing schedules, follow-ups, document management.

Each component can be a separate tool or bundled into a multi-purpose platform. The right configuration depends on firm size and complexity.

CRM choice for London property

The major property CRMs used in London:

Reapit. Market leader for established London estate agents and lettings firms. Comprehensive functionality, strong integration with major portals, mature support. Pricier than alternatives but the standard for serious firms.

Alto. Owned by Zoopla. Strong integration with Zoopla and the broader portal ecosystem. Popular for mid-sized London firms.

Dezrez. Particularly strong for letting agents and property managers. Good workflow tools for tenancy management.

Vebra. Owned by RightMove. Tightly integrated with the portal. Used by firms that lean heavily on RightMove for distribution.

Acquaint CRM. Mid-market option with good basic functionality.

HubSpot or Salesforce with property add-ons. For developers and BTR operators with complex marketing needs that the property-specific CRMs do not handle well. Typically combined with a property-specific tool for the transaction layer.

The choice for an estate agent typically comes down to Reapit, Alto, or Dezrez based on firm size and existing portal relationships. The choice for a developer typically comes down to whether to use a property-specific CRM (limited marketing capability) or a marketing CRM (limited property workflow capability) and accept the gaps.

The integration that matters most

The single most important integration in any property tech stack is the connection between the website forms and the CRM.

Every enquiry, regardless of channel, should flow into the CRM within minutes. The contact record should include the source (which page, which campaign, which UTM parameters), the property of interest if applicable, and any criteria the buyer or tenant specified.

Most property firms have this connection partially working. Web form leads flow to one place. Portal leads flow to another. Phone enquiries are captured manually if at all. Walk-ins are handled in a separate diary. The result is a fragmented view of the customer that prevents the marketing team from acting on the data effectively.

The fix takes development time but is foundational. Webhook integrations from website forms, portal API integrations, call tracking integrations, and walk-in capture flows should all converge on a single CRM record per contact.

Marketing automation for property

The marketing automation layer is where most property firms underinvest. The CRM has basic email functionality. The team uses it to send occasional broadcasts. The automation features sit unused.

The triggered automations that matter for property:

The new enquiry confirmation, sent within minutes of form submission.

The viewing reminder, sent 24 hours before a booked viewing.

The post-viewing follow-up, sent 2 hours after a viewing with relevant next-step content.

The nurture sequence for buyers and tenants who have not yet viewed.

The market update emails, sent quarterly to the firm's full database with localised commentary.

The renewal reminder for tenancies, starting 90 days before expiry.

The completion follow-up, sent 30 days after a transaction with a review request and post-transaction guidance.

Each of these automations is configured once and runs in perpetuity. The cumulative effect on conversion and retention is substantial.

For firms whose CRM has weak automation, layer in HubSpot or ActiveCampaign for the marketing communications while keeping the property CRM for transaction workflow. The integration takes a developer-week but unlocks significantly better marketing capability.

Analytics and attribution

Most property firms run with weak attribution. They know how many leads came in last month. They do not know which channels produced them, which converted to viewings, which closed.

The analytics setup that matters:

Google Analytics 4 properly configured on the website, with conversion events for form submissions, phone clicks, and downloads.

UTM parameters consistently applied to all paid media, email campaigns, and external partnerships. The CRM should capture these UTMs on every lead.

Call tracking via CallRail, Whisper, or equivalent. Phone calls are a significant source of property enquiries and most firms have no idea how many came from which channel.

Closed-loop reporting from the CRM back to the marketing channels. When a lead converts to a sale or tenancy, that information should flow back to Google Ads, Meta Ads, and the analytics platform. The platforms' algorithms work dramatically better with conversion data feeding back.

A firm with proper closed-loop attribution can answer the question "what is our cost per closed transaction by channel?" within 60 seconds. Most firms cannot answer it at all.

Property-specific PropTech worth considering

Beyond the CRM and marketing layer, several PropTech tools add specific capabilities:

Lifesycle. Specialist marketing automation for estate agents, integrated with major property CRMs.

iamproperty. Auction and modern method of sale platform. Useful for firms that want to add auction capability.

Goodlord. Tenant referencing and tenancy management for letting agents. Streamlines the post-offer to move-in workflow.

Kerfuffle. Industry directory and review platform for property tech. Useful for vetting tools before adoption.

Twentyci. Market intelligence and competitive analysis. Used by larger firms for strategic insights.

Reapit Foundations / Alto Connect / Dezrez Inspire. The marketing modules within the major CRMs. Most firms underuse these. Worth auditing what you already have access to before adding tools.

Stack maturity by firm size

The right stack varies by firm scale:

Solo agent or small lettings firm (1 to 10 staff): a single property CRM with built-in basic marketing functionality is enough. Reapit Lite, Alto Standard, or similar. Avoid over-tooling.

Mid-sized firm (10 to 50 staff): the full property CRM, plus call tracking, plus a basic marketing automation tool. Closed-loop attribution becomes important at this scale.

Large firm or developer (50+ staff): the property CRM for transactions, a separate marketing CRM for the broader pipeline (HubSpot or similar), full attribution stack, dedicated analytics support. The complexity is higher but so is the leverage.

Match the stack to the firm size. Over-tooling small firms produces tools nobody uses. Under-tooling large firms produces capability gaps that limit growth.

What to fix this quarter

If your stack feels fragmented:

Week one: audit every lead source and confirm where each lands. Map the gaps.

Week two: fix the most painful integration. Usually the website-to-CRM connection or the portal-to-CRM connection.

Week three: configure the highest-value automation that is currently missing. Usually the post-viewing follow-up or the new enquiry confirmation.

Week four: set up basic closed-loop attribution by ensuring CRM transaction status flows back to your analytics platform.

Each fix produces measurable improvement within 30 to 60 days. The compound effect over 12 months is the difference between a firm running a marketing engine and a firm running a list of disconnected tools.
