"I want to implement an MA tool, but there are too many options to choose from"—this is something we hear constantly from marketing professionals. MA tools (marketing automation) are software that automates and streamlines the entire process from lead generation to nurturing and handoff to the sales team. In Japan, the number of companies adopting MA tools has roughly doubled compared to pre-COVID levels, making them increasingly standard infrastructure for B2B marketing.
In this article, drawing on the perspective of a SaaS developer who has built API integrations with numerous MA products, we systematically cover how to choose an MA tool, compare major products, and walk through implementation steps that assume API integration from the start. This goes beyond a simple feature comparison to address the design philosophy of how to position an MA tool within your overall marketing stack.
MA tool stands for Marketing Automation—software designed to automate and streamline lead generation, nurturing, and hot lead extraction. Specific capabilities include email automation, website behavior tracking, lead scoring, and scenario-based nurturing workflows.
The core value of an MA tool lies in building a system that delivers the right content, to the right person, at the right time. It enables personalized communication at a scale impossible to achieve manually and strengthens the alignment between marketing and sales teams.
MA tool features span a wide range but can be organized into three phases: Lead Generation (acquisition), Lead Nurturing (cultivation), and Lead Qualification (selection). Lead Generation includes landing page creation, form setup, and web behavior tracking to identify anonymous visitors. Lead Nurturing centers on email automation, drip campaigns, and scenario design. Lead Qualification uses behavior-based scoring to automatically extract hot leads and hand them off to sales.
To avoid making a poor MA tool selection, here are five evaluation criteria valued in the SaaS development world. Rather than choosing based on feature count alone, it is critical to assess alignment with your overall marketing stack.
Few MA tools deliver full value in isolation. They truly shine when integrated with CRM, SFA, ad platforms, BI tools, and other systems. During selection, evaluate not just which tools offer standard integrations, but also whether the API design is RESTful, whether Webhooks are supported, whether API documentation is well-maintained, and whether rate limits are practical. Choosing a tool with weak API integration capabilities leads to expensive custom development down the road.
B2B and B2C leads are fundamentally different in nature. B2B involves multiple decision-makers within a single company and longer consideration cycles, making account-based lead management and scoring essential. B2C, on the other hand, requires segmented messaging at scale, LINE/SMS integration, and e-commerce connectivity. Choosing a tool that matches your business model directly impacts post-implementation adoption rates.
From a SaaS developer’s perspective, custom field and custom object flexibility is particularly important. As your business grows, standard lead fields become insufficient. The ability to store and leverage company-specific data—product usage metrics, customer success information, proprietary scoring logic—determines the long-term investment value of your MA tool.
MA tool pricing models generally fall into three categories: per-account, per-contact, and usage-based (by feature or volume). Simulate not just initial costs but how monthly fees change if your lead volume grows tenfold. Whether you can start small is also an important consideration—some tools start at a few hundred dollars per month while others require significant upfront investment.
Implementing an MA tool is not the end—operational adoption is the real challenge. Compare non-functional support quality: local language support availability, dedicated customer success managers, initial consulting, and online community richness. For international tools, having a local subsidiary directly impacts the depth of support.
MA tools can be broadly classified into three types: all-in-one, feature-specialized, and industry-specialized. Below, we cover major products by category.
HubSpot Marketing Hub is the quintessential all-in-one platform, offering CRM, SFA, CMS, and customer service on a single platform. Its scalability—starting with a free plan and upgrading as you grow—is a key strength. The API design is excellent, supporting both RESTful APIs and Webhooks with extensive developer documentation. End-to-end data integration from marketing through sales to customer success makes it highly compatible with SaaS businesses.
Adobe Marketo Engage is a high-capability enterprise MA tool. Its lead nurturing and scoring precision are industry-leading, with complex multi-touch attribution analysis capabilities. Integration with the broader Adobe Experience Cloud enables cross-channel customer experience design spanning ads, web, and email. The tradeoff is that initial setup and operations require specialized expertise, and many companies engage system integrators for implementation.
b→dash is a Japanese-built platform offering 16 functions in one package, including CDP, MA, BI, and web personalization. Its standout feature is no-code, SQL-free operation that enables data utilization without engineering resources. AI-powered send-time optimization helps reduce operational effort while maximizing campaign results.
SHANON MARKETING PLATFORM has been adopted by over 3,000 companies in Japan. It offers AI-assisted form and web page creation alongside bidirectional integration with external SFA/CRM systems for real-time data synchronization with sales teams. Its Digital Plan starts at around 60,000 yen/month, making it accessible for small starts.
BowNow holds the top domestic market share among B2B MA tools. With a free plan available, it presents a low barrier to entry for first-time MA adopters. Its streamlined feature set focused on essentials makes it easy to operate even with small teams.
List Finder specializes in converting hot leads into sales meetings. With no initial setup fee and a light plan starting around 40,000 yen/month, it offers strong cost performance. A dedicated consultant accompanies users for the first six months, contributing to a 99% retention rate.
SATORI is unique among Japanese MA tools for its "unknown marketing" capability—enabling outreach to anonymous visitors who have not yet submitted personal information. This makes it effective from the very earliest stages of lead acquisition.
Zoho CRM is an integrated tool centered on CRM/SFA with built-in MA capabilities. Its paid plans are more affordable compared to competitors, with no initial fees. Developed primarily for B2B, customization features also support B2C use cases. However, localization for the Japanese market may lag slightly behind other global tools.
To unlock the true potential of an MA tool, integration design with other SaaS tools is essential. Here, from a SaaS developer’s perspective, we explain the integration patterns and technical considerations you should plan during implementation.
MA-to-CRM/SFA integration is the most fundamental and important pattern. Scored hot leads from the MA tool automatically flow to the SFA so sales reps can act immediately. The technical considerations are sync direction and sync frequency. Some cases only need one-way sync from MA to SFA; others require bidirectional sync where deal status changes flow back to MA for scoring. Drawing a data flow diagram during requirements definition—specifying which fields sync in which direction at what frequency—is the key to integration success.
Integrating Google Ads or Meta Ads with your MA tool lets you use MA lead data as audience lists for ad targeting. For example, syncing email addresses of leads above a certain score as custom audiences and generating lookalike audiences to expand reach. Feeding back conversion data via Conversion APIs—tracking whether ad-acquired leads progressed to deals or closed-won—dramatically improves ad optimization accuracy.
Standard MA reporting often lacks the granularity needed for executive decision-making. API integration with BI tools enables cross-functional dashboards combining MA campaign data, lead behavior data, SFA deal data, and even product usage data. This supports attribution analysis and marketing ROI visualization—building an analytics environment robust enough for C-suite reporting.
Not every integration requires custom development. iPaaS tools like Zapier or Make (formerly Integromat) enable no-code connections between MA tools and other SaaS products. For example, sending a Slack notification when a lead reaches a certain score, or creating a CRM record triggered by a form submission. However, iPaaS integrations have limitations around data latency and error handling, so direct API integration is recommended for mission-critical data flows.
MA tool implementation is a comprehensive project encompassing not just tool selection but also organizational readiness and data architecture. Following these five steps will increase post-launch adoption rates.
Set specific numerical targets such as "increase new leads to 200 per month" or "achieve 30%+ MQL-to-SQL conversion rate." Vague objectives lead to underutilized or mismatched features. It is important to build KPI consensus not just within marketing, but involving sales and IT stakeholders as well.
List all currently used CRM, SFA, email tools, web analytics, and ad management tools, then map out their data fields and integration methods. Skipping this step leads to post-launch issues like integration failures and duplicate data management. From a SaaS developer’s perspective, we strongly recommend collecting API specifications for each tool in advance and drawing data flow diagrams.
Narrow your candidates to 2–3 tools and conduct a PoC using free trials or demo environments. Key areas to evaluate: UI usability, ease of API integration, reporting flexibility, and support response speed. For API integration specifically, actually building a CRM integration in a test environment dramatically improves documentation quality assessment and development effort estimation accuracy.
After selecting your tool, design the lead data model, define scoring rules, create email templates, and build nurturing scenarios. The most critical element is defining lead lifecycle stages. Align marketing and sales on stages like Anonymous Visitor → Known Lead → MQL → SQL → Opportunity → Customer, with clear transition criteria for each. Ambiguous definitions here cause confusion during lead handoffs.
After launch, treat the first three months as a learning period and start with small initiatives. Monitor KPIs weekly—drip email open rates, click rates, scoring accuracy, MQL-to-SQL conversion rates—and run hypothesis-testing cycles. MA tools are not designed for short-term wins; they improve through accumulated data and scenario refinement. Evaluate ROI over a 6–12 month horizon.
MA tool implementations fail for several common reasons. The most frequent is selecting a feature-heavy tool that the team cannot operationalize. The more sophisticated the tool, the steeper the learning curve. Choose a tool matched to your organization’s marketing maturity.
The second most common failure is insufficient content. An MA tool is merely a delivery mechanism—without adequate content (whitepapers, blog posts, case studies, webinars), even well-designed scenarios yield limited results. Audit your content inventory and create a production plan before implementation.
From a SaaS developer’s standpoint, another frequent pitfall is deferring integration design. Attempting CRM integration after MA implementation often leads to data structure mismatches and field mapping errors. Start integration design during the tool selection phase and include API validation in your project timeline—this ultimately shortens overall implementation time.
MA tools are not meant to be implemented in isolation—they deliver maximum value when integrated with CRM, SFA, ad platforms, and BI tools. The most effective selection approach is to first design which tools need to exchange which data in which direction, then choose the MA tool that meets those requirements.
Define your objectives, audit your existing stack, run a PoC, design your data architecture, and establish PDCA cycles for operational adoption. By following these five steps diligently, your MA tool will function not as a cost center but as a revenue-generating engine. Choose an MA tool that fits your business model and growth stage, and realize the full potential of marketing automation and optimization.
