Best Email Marketing Tools for B2B SaaS in 2026

Sequenzy has emerged as a standout choice for B2B SaaS companies seeking email automation that truly understands the subscription business model. What sets Sequenzy apart is its native integration with billing platforms including Stripe, Polar, Creem, and Dodo. This billing-first approach means your email segmentation and triggers can be based on actual revenue data - MRR per account, plan tier, billing status, and subscription lifecycle events. For B2B SaaS where revenue metrics drive everything, this native billing awareness eliminates the integration complexity that plagues other tools.

The account-based marketing capabilities in Sequenzy stem from its billing integration rather than traditional CRM data. Because billing systems naturally group users by subscription and company, Sequenzy can segment your email campaigns by account-level metrics like total MRR, number of seats, plan type, and expansion behavior. You can target emails to accounts approaching their usage limits, companies on annual plans coming up for renewal, or teams that recently upgraded. This revenue-centric view of accounts is particularly valuable for self-serve and product-led B2B SaaS where the billing system is often more accurate than CRM data.

For B2B SaaS startups and growth-stage companies, Sequenzy's pricing is compelling. At $19/month for up to 20,000 emails, it costs a fraction of enterprise tools while providing sophisticated automation capabilities. The platform supports behavioral triggers, multi-step sequences, and dynamic content - the building blocks of effective B2B email automation. While it lacks some enterprise features like advanced CRM integration and multi-channel campaigns, these limitations rarely matter for teams focused on product-led or hybrid B2B motions where billing data is the primary source of customer truth.

The ideal Sequenzy customer is a B2B SaaS company with a self-serve or low-touch sales model, strong reliance on billing data for customer segmentation, and a need for affordable automation that scales with growth. If your B2B go-to-market involves significant sales-assisted deals requiring deep CRM integration, you may need to supplement Sequenzy with other tools. But for the many B2B SaaS companies where billing is the heartbeat of customer relationships, Sequenzy provides exceptional value.

Ortto, formerly known as Autopilot, has evolved into a comprehensive customer data platform with powerful B2B email marketing capabilities. The platform's strength lies in its unified approach to customer data, combining email automation, analytics, and customer journey orchestration in one interface. For B2B SaaS companies drowning in disconnected tools and fragmented customer data, Ortto provides a single source of truth that powers smarter email campaigns and better account intelligence.

The account-based marketing features in Ortto benefit from its customer data platform foundation. The platform can aggregate data from multiple sources - your product, CRM, support tickets, and more - to build complete account profiles. This unified view enables sophisticated B2B segmentation based on firmographics, engagement patterns, product usage, and custom attributes. Account scoring models can incorporate any data point, helping marketing and sales prioritize outreach to the accounts most likely to convert or expand.

Ortto's visual journey builder excels at creating complex B2B email sequences that adapt to account behavior. You can design multi-path journeys that respond differently based on role, engagement level, or account stage. The platform supports both automated marketing emails and sales-triggered communications, making it valuable for B2B companies with hybrid go-to-market motions. Built-in analytics show how email campaigns influence pipeline and revenue, addressing the measurement challenges that plague B2B marketing.

The main consideration with Ortto is pricing and complexity. Starting at $99/month and scaling with contacts and features, it represents a significant investment compared to simpler tools. The breadth of capabilities can also mean a steeper learning curve. Ortto is best suited for B2B SaaS companies that have outgrown basic email tools and need a unified platform for customer data and marketing automation. Teams seeking a CDP without enterprise-level pricing and implementation complexity find Ortto hits a useful middle ground.

Customer.io has established itself as the power user's choice for behavioral email automation, with capabilities that scale from startup to enterprise B2B. The platform's event-based architecture allows you to trigger emails from virtually any user or account action, making it ideal for B2B SaaS companies with complex product interactions. You can build sophisticated multi-step workflows that respond to product usage, support interactions, sales activities, and custom events from any system in your stack.

For B2B account-based marketing, Customer.io supports company objects with relationships to individual users. This data model enables true account-level operations: segmenting companies by collective attributes, triggering campaigns when account-level conditions are met, and personalizing emails with company data. You can track when any user at a company completes an action, score accounts based on total engagement, and coordinate messaging across all contacts at a target organization.

The CRM integration capabilities in Customer.io satisfy enterprise B2B requirements. Native integrations with Salesforce, HubSpot, and other CRMs synchronize contact data, track email engagement in CRM records, and trigger emails based on sales pipeline changes. The bi-directional sync ensures sales teams see marketing engagement while marketing campaigns can respond to sales activities. This alignment is crucial for B2B companies where deals require coordination between automated marketing and human sales touchpoints.

Customer.io's learning curve and pricing reflect its power. Starting at $100/month and scaling with profile count, it costs more than basic tools but delivers enterprise-grade capabilities. The workflow builder requires technical comfort, and maximizing the platform's potential often involves developer resources for event tracking integration. B2B SaaS companies with technical teams, complex product interactions, and sophisticated automation needs find Customer.io worth the investment. Simpler use cases may be better served by more accessible tools.

HubSpot has become synonymous with inbound B2B marketing, offering an integrated platform that combines email marketing, CRM, sales tools, and customer service. For B2B SaaS companies seeking an all-in-one solution that eliminates integration headaches, HubSpot provides a comprehensive ecosystem where marketing and sales data flow seamlessly. The platform pioneered the inbound methodology, making it particularly strong for B2B companies that rely on content marketing and organic lead generation.

The account-based marketing capabilities in HubSpot, available in higher tiers, include target account selection, account scoring, and company-level reporting. The native CRM provides a solid foundation for B2B operations, with company records that aggregate individual contacts, track engagement across the account, and surface buying signals. Sales and marketing teams share the same data, eliminating the misalignment that plagues B2B organizations using disconnected tools.

For CRM-centric B2B companies, HubSpot eliminates the integration question entirely. Email marketing performance flows directly into CRM records, sales sequences can trigger marketing workflows, and customer service interactions inform both teams. The platform includes lead scoring, workflow automation, and revenue attribution out of the box. Marketing teams appreciate the user-friendly interface, while sales teams benefit from context about marketing engagement when working deals.

The consideration with HubSpot is cost at scale. While entry-level pricing starts around $45/month, accessing full marketing automation and ABM features requires professional or enterprise tiers that cost significantly more. The platform can also feel limiting for teams that need deep customization or want to integrate best-of-breed tools. HubSpot is ideal for B2B SaaS companies committed to the HubSpot ecosystem, valuing simplicity and integration over maximum flexibility, and able to budget for growth into higher pricing tiers.

Userlist was built from the ground up specifically for B2B SaaS, making it unique among email automation platforms. While other tools have added B2B features as afterthoughts, Userlist's entire data model centers on the company-user relationship fundamental to B2B. Every feature, from segmentation to automation to analytics, understands that your customers are companies made up of multiple users with different roles, permissions, and engagement patterns.

The company-level tracking in Userlist is unmatched. Users automatically associate with companies, and you can segment and message at either level. Create segments of companies based on aggregate user behavior, total seats, MRR, or custom company attributes. Build automation workflows that trigger when any user at a company takes an action, or when company-level metrics cross thresholds. The platform natively understands the B2B concept that a "customer" is an organization, not an individual.

For account-based marketing, Userlist provides the infrastructure that other tools require workarounds to achieve. View engagement dashboards at the company level, seeing total email opens, feature adoption, and health scores across all users. Send targeted campaigns to specific accounts or account segments. Personalize messages with company attributes alongside individual data. The platform's B2B-native approach means these capabilities work out of the box rather than requiring custom configuration.

Userlist's specialization is both its strength and limitation. Starting at $100/month, it competes on features rather than price, and the investment is justified for B2B SaaS companies that need deep company-level capabilities. However, teams seeking a broader marketing platform with landing pages, forms, and CRM will need to integrate Userlist with other tools. Userlist excels for B2B SaaS companies that prioritize email automation and need company-level operations as a core capability, not a bolted-on feature.

ActiveCampaign bridges the gap between email marketing and CRM, making it particularly valuable for B2B SaaS companies with sales-assisted go-to-market motions. The platform combines sophisticated email automation with a built-in CRM that tracks deals, manages pipelines, and maintains the sales context needed for B2B success. For teams where marketing and sales must work closely together, ActiveCampaign provides unified tools without requiring separate system integration.

The B2B features in ActiveCampaign center on the connection between marketing automation and sales activities. Lead scoring identifies which contacts are sales-ready, and scores can incorporate email engagement, website visits, and custom attributes. Automation workflows can trigger sales tasks, update deal stages, or notify reps when leads take key actions. The bi-directional flow between marketing emails and sales activities ensures both teams see the full customer picture.

For account-based marketing, ActiveCampaign's CRM provides the company-level organization that B2B requires. Contacts associate with accounts, deals link to companies, and you can view engagement and pipeline at the organizational level. While not as deeply B2B-native as Userlist, the combination of email automation and CRM covers most B2B use cases. The visual automation builder makes complex B2B sequences accessible to non-technical marketers.

ActiveCampaign's value proposition is strong for sales-assisted B2B at accessible pricing. Starting at $29/month, it costs less than many competitors while providing both marketing automation and CRM. The tradeoff is that neither component matches dedicated best-of-breed tools - the CRM is lighter than Salesforce, and the automation is less powerful than Customer.io. For B2B SaaS companies that need good-enough capabilities in both areas from a single affordable platform, ActiveCampaign delivers excellent value.

Intercom takes a fundamentally different approach to B2B communication by unifying email, live chat, chatbots, help desk, and product tours in one platform. For B2B SaaS companies where customer communication spans multiple channels and touchpoints, Intercom eliminates the fragmentation of using separate tools for each function. The platform's strength is reaching customers through the right channel at the right time, whether that means an email, an in-app message, or a chat conversation.

The B2B capabilities in Intercom include company tracking, account-based targeting, and multi-stakeholder communication. You can view all users at a company in a unified timeline, seeing email engagement alongside chat conversations and support tickets. Send targeted campaigns to specific accounts or account segments. The combination of outbound email and in-app messaging is particularly powerful for B2B product-led motions where you want to reach users in context rather than competing for inbox attention.

For enterprise B2B, Intercom provides the multi-channel capabilities that sophisticated buyers expect. When prospects have questions, they can chat in real-time. When customers need support, tickets flow into the same system. Product announcements can go via email, in-app, or both. This unified approach means every team has context about customer interactions, and customers experience consistent communication regardless of channel. CRM integrations sync Intercom data with sales tools.

Intercom's breadth comes with complexity and cost. Starting at $74/month for basic plans and scaling significantly for full features, it represents a substantial investment. The platform can feel overwhelming for teams that just need email automation, and the pricing model based on people reached can surprise growing companies. Intercom is ideal for B2B SaaS companies committed to multi-channel customer communication, willing to invest in a unified platform, and able to leverage capabilities beyond email.

Klaviyo built its reputation in e-commerce email marketing but has been expanding into B2B with its powerful data platform and segmentation capabilities. The platform excels at collecting, unifying, and acting on customer data, creating detailed profiles that power highly personalized email campaigns. For B2B SaaS companies that think of email marketing as a data problem, Klaviyo's CDP-like capabilities offer sophisticated segmentation and personalization.

The data infrastructure in Klaviyo translates well to B2B use cases. The platform can ingest data from multiple sources, build unified customer profiles, and enable segmentation based on any attribute or behavior. Predictive analytics, powered by machine learning, can identify which accounts are likely to convert, churn, or expand. These data capabilities, originally designed for e-commerce predictions, apply equally to B2B customer lifecycle management.

For B2B account-based marketing, Klaviyo provides tools to segment and personalize at scale, though the company-level features are less developed than B2B-native tools. You can create sophisticated segments based on company attributes, build dynamic content blocks that personalize emails with account data, and track engagement metrics that inform sales prioritization. The visual email builder and template library make professional B2B emails accessible to non-designers.

Klaviyo's B2B offering is evolving, with the platform increasingly targeting SaaS and subscription businesses beyond its e-commerce roots. Starting at $45/month, pricing is competitive, though costs scale with contact count. B2B SaaS companies that value data sophistication and predictive capabilities may find Klaviyo's expanding B2B features sufficient, while teams requiring deep company-level operations may prefer purpose-built B2B tools. Watch this space as Klaviyo continues developing B2B-specific functionality.

Drip originated as an e-commerce automation platform but its event-driven architecture translates effectively to B2B SaaS use cases. The platform's strength lies in its visual workflow builder and ability to trigger emails from custom events, making it flexible enough to handle B2B customer journeys. For B2B teams that want powerful automation without enterprise complexity, Drip provides an accessible middle ground between basic tools and platforms like Customer.io.

The automation capabilities in Drip support B2B sequences including onboarding flows, trial conversion campaigns, and expansion outreach. You can trigger emails from product events, segment based on feature usage, and build multi-step workflows that adapt based on engagement. The visual builder makes it easy to map out complex B2B journeys with conditional logic, delays, and multiple paths. Revenue tracking, while originally designed for e-commerce, works for B2B when integrated with billing systems.

For B2B segmentation, Drip offers tagging, custom fields, and event-based segments. While company-level tracking requires workarounds compared to B2B-native tools, you can achieve reasonable account organization using company identifiers in contact properties. The platform integrates with popular B2B tools including CRMs, payment processors, and product analytics, though integration depth varies. API access allows custom integrations for specialized B2B data flows.

Drip's pricing starts at $39/month, positioning it as an affordable option for B2B SaaS companies that need more automation capability than basic tools provide. The platform lacks some enterprise B2B features like native company tracking and advanced ABM tools, but covers the fundamentals well. Drip is well-suited for B2B SaaS companies in the mid-market, seeking visual automation building, and comfortable with some manual configuration for B2B-specific use cases.

Encharge was purpose-built for SaaS behavioral marketing, making it naturally suited for B2B SaaS companies that want to email based on product usage. The platform understands the SaaS customer lifecycle from trial to paid to expansion, with built-in templates and workflows for common SaaS scenarios. For B2B teams that want automation specifically designed for software companies rather than adapted from e-commerce or general marketing, Encharge delivers relevant functionality out of the box.

The behavioral tracking in Encharge captures product events that drive B2B email relevance. Track feature adoption across teams, identify accounts with declining engagement, and trigger outreach based on usage milestones. The platform includes pre-built segments for common B2B SaaS scenarios like trial users who have not reached activation, customers approaching usage limits, and accounts with low engagement scores. This SaaS-specific context reduces the configuration time compared to general-purpose tools.

For B2B account-based marketing, Encharge supports company-level tracking with the ability to group users by organization and segment based on account attributes. You can target emails to accounts rather than individuals, track engagement at the company level, and build automation that responds to collective team behavior. Integration with Segment, Intercom, and CRM systems allows Encharge to incorporate data from across your B2B stack into segmentation and personalization.

Encharge pricing starts at $79/month, positioning it between budget tools and enterprise platforms. The SaaS-specific features justify the premium over basic email tools for B2B companies that will use the behavioral capabilities. The platform may be overkill for simple newsletter-style B2B communication, but excels when product usage data should drive email strategy. Encharge is ideal for B2B SaaS companies with product-led elements, strong product instrumentation, and a need to connect email to feature adoption journeys.

Mailchimp needs no introduction as the most recognized email marketing platform, and it has been expanding its capabilities to serve B2B use cases. While not purpose-built for B2B SaaS like some competitors, Mailchimp's broad feature set, user-friendly interface, and widespread adoption make it a viable starting point for B2B companies. The platform's familiarity can be valuable for teams with limited technical resources or those prioritizing ease of use over specialized B2B features.

The automation capabilities in Mailchimp have grown substantially, now supporting behavioral triggers, multi-step journeys, and conditional logic. You can create B2B sequences for onboarding, nurturing, and retention, though the workflow builder is less sophisticated than specialized tools. Audience segmentation supports custom fields and tags that can represent B2B attributes like company size, industry, or plan type. The interface makes these features accessible to non-technical marketers.

For B2B needs, Mailchimp offers growing but limited functionality. Company-level tracking requires manual setup using contact properties rather than native account objects. CRM integration exists through third-party connections but lacks the depth of platforms like HubSpot or ActiveCampaign. The platform has been adding landing pages, websites, and scheduling features that create an all-in-one small business suite, though B2B SaaS-specific features remain limited compared to purpose-built tools.

Mailchimp's value proposition for B2B is accessibility and familiarity at competitive pricing starting around $20/month. The free tier allows teams to start without investment, and the learning curve is gentler than specialized platforms. B2B SaaS companies in early stages, with simple email needs, or with limited technical resources may find Mailchimp sufficient. As B2B requirements grow more sophisticated - account-based targeting, deep product integration, advanced automation - teams typically graduate to more specialized tools.
