Automated email marketing is one of the most proven ways to grow revenue without scaling your team proportionally. Email automations deliver 30 times more revenue per recipient than one-off promotional campaigns, with the average return per recipient for automated flows reaching $1.94 versus $0.11 for standard campaigns. But to get there, you need to choose the right system. The answer to which systems support automated email marketing spans five distinct categories: dedicated email service providers, CRM platforms with built-in automation, ecommerce-native tools, marketing automation suites, and creator-focused platforms. This guide breaks down each category with the data and context you need to make a confident decision.
Key Takeaways
- Automated messages generated 37% of all email-attributed sales in 2024, despite representing just 2% of email volume.
- HubSpot leads for CRM-first teams, combining automation, email, and pipeline in one platform. ActiveCampaign offers the deepest automation logic for B2B and SaaS, with strong behavioral branching, lead scoring, and lifecycle workflows.
- Brevo is the most cost-effective option for high-volume senders, with email, SMS, and WhatsApp natively integrated.
- Klaviyo has become a go-to automation platform for online stores, particularly those on Shopify, standing out for its deep ecommerce integration and advanced tools.
- The global marketing automation software market, valued at approximately $7.23 billion in 2025, is projected to surge toward $20.12 billion by 2034.
Why Choosing the Right System Matters
As of early 2024, email was the channel that relied on marketing automation more than any other, with 58% of surveyed professionals choosing it over both content and social media management. That reliance is justified by the numbers: email consistently generates a return on investment between $36:1 and $42:1, dramatically outperforming social media, paid search, and display advertising.
The system you pick determines how much of that potential you actually unlock. 82% of marketers use automation to create triggered emails, which result in 8 times more opens and greater earnings than typical bulk emails. But not all platforms execute this equally. The differences in automation depth, CRM connectivity, deliverability infrastructure, and pricing create very different outcomes depending on your business model.

1. Dedicated Email Service Providers (ESPs)
Dedicated ESPs are purpose-built for email creation, automation, and delivery. They are the most common starting point for businesses exploring which systems support automated email marketing.
Mailchimp
Mailchimp offers ecommerce-specific automation triggers such as when a customer purchases a product, abandons their cart, or views a certain Shopify store page, and has added several more recently including Abandoned Browse, Back in Stock, and Predicted Purchase Date. It integrates with hundreds of apps and remains the most recognized entry-level platform.
That said, Mailchimp has trade-offs. Unlike most providers, Mailchimp charges for inactive contacts, including bounced and unsubscribed ones. For smaller lists with simple needs, it works well. For complex automation, there are stronger options.
MailerLite
MailerLite's automation tools stand out as a major strength for its price point, covering welcome emails, abandoned cart emails, and audience segmentation. You can build relatively advanced workflows with multiple triggers and actions. The automation editor is simple to use, even for beginners, though it is better suited for small to midsize companies rather than complex enterprise automations. Paid plans start at just $9 per month, including unlimited emails and three account users.
Brevo
Brevo is an email marketing and CRM platform for small businesses, ecommerce brands, and marketers, offering SMS marketing, CRM, and transactional emails alongside email campaigns. It suits businesses wanting to manage multiple communication channels in one place. Brevo's main differentiator is its send-based pricing model. While most platforms charge based on contact count, Brevo prices plans based on email volume, allowing unlimited contacts on most plans.
2. Advanced Marketing Automation Platforms
These platforms go beyond email into full customer lifecycle management, making them the right answer to which systems support automated email marketing for mid-market and enterprise teams.
ActiveCampaign
ActiveCampaign offers the most sophisticated automation with 900+ pre-built workflows, conditional splits, goals, and machine learning-powered predictive sending. The built-in CRM aligns marketing and sales, with automated lead scoring and deal creation eliminating the need for separate CRM software for most teams.
Marketing teams using ActiveCampaign save an average of 10 hours weekly across tasks like campaign building, content creation, and lead follow-up. It connects to 1,000 integrations, including major ecommerce platforms like Shopify, BigCommerce, and WooCommerce, with 900+ workflow templates.
The platform does have a steeper learning curve. It is best suited for B2B companies, agencies, and businesses with complex customer journeys, though reporting can be overwhelming for beginners and pricing jumps significantly as the list grows.
HubSpot Marketing Hub
HubSpot connects email marketing directly to its native CRM, giving revenue teams a single platform for contact management, automation, and campaign execution. It is built for mid-market B2B teams that want marketing and sales data in the same system.
CRM-powered email automation lets you trigger emails based on deal stages, contact properties, and behavioral signals, all pulling from the same CRM data your sales team uses. HubSpot has shed its SMB-only reputation. With the launch of Breeze AI and advanced Workspaces, it now offers the governance and power required by large organizations while retaining its signature usability.
Cost is a real consideration. HubSpot's free CRM is generous, but Marketing Hub Professional, where real automation and A/B testing live, starts at around $890 per month plus a mandatory onboarding fee.
3. Ecommerce-Native Automation Platforms
For online stores, the most important factor in choosing an automated email system is how tightly it integrates with your store data.
Klaviyo
Klaviyo is the undisputed leader in ecommerce email marketing, powering brands that have generated over $45 billion in attributed revenue through the platform. Recently, Klaviyo has enhanced its platform with AI-driven tools that predict customer behavior, simplify the way you build marketing automations, and help to generate email content.
Klaviyo's data model is built around ecommerce events, including purchase history, predictive lifetime value, churn risk, and next-purchase date, in ways that most other platforms do not natively replicate. Klaviyo uses AI to offer predictive analytics, providing insights into metrics like customer lifetime value, churn risk, and expected next order date.
The trade-off is cost. Klaviyo's pricing structure can be steep, particularly for businesses with large contact lists.
Omnisend
Omnisend is built specifically for ecommerce and works well with both Shopify and WooCommerce. It combines email, SMS, push notifications, and automation in a user-friendly interface. Many merchants choose Omnisend because it offers strong ecommerce features without requiring a steep learning curve.
The platform includes prebuilt workflows for welcome emails, cart recovery, order confirmation, product abandonment, and customer reactivation. For stores earlier in their automation journey, Omnisend is a strong entry point before graduating to Klaviyo.

4. CRM Platforms with Email Automation
Many businesses already have CRM data that should be powering their email automation. Several CRM platforms now include robust native email marketing capabilities.
Salesforce Marketing Cloud
Salesforce holds the largest share of the CRM market globally according to IDC's 2025 rankings, and its email marketing capabilities reflect that scale. The platform connects Sales Cloud with Marketing Cloud to deliver sophisticated segmentation, journey orchestration, and multi-channel automation.
The barrier is access. Configuring and maintaining Salesforce's email marketing capabilities typically requires dedicated Salesforce administrators or RevOps support, and accessing advanced email features means purchasing Marketing Cloud on top of Sales Cloud, which can make the total investment prohibitive for mid-market teams.
Zoho CRM
Zoho CRM is a cost-effective and full-featured CRM, making a strong choice for SMBs or mid-market companies that want decent automation without an enterprise budget. Features include lead and deal management, sales automation, and advanced workflows. Zoho Campaigns integrates directly with Zoho CRM for list syncing and triggered email sequences.
5. Creator and SMB-Focused Platforms
Not every business needs enterprise-grade automation. Several platforms exist specifically for smaller teams, creators, and service businesses.
Kit (formerly ConvertKit)
Rebranded from ConvertKit in October 2024, Kit serves creators with 93.9% of its users having 1 to 10 employees, the highest micro-business concentration of any platform tracked, making it the default email tool for bloggers, podcasters, YouTubers, and online course instructors.
What makes Kit distinctive is its visual automation builder combined with a tagging-first subscriber model. Where other platforms organize contacts by lists, Kit organizes by behavior, making it natural for creators to build sophisticated sequences without technical expertise.
GetResponse
GetResponse is best for teams that also need webinar and conversion funnel tools alongside email automation, and offers competitive pricing on mid-size lists. It is not a specialized ecommerce tool but has features for ecommerce stores including cart abandonment and purchase automations, push notifications, chat, promo codes, and payment gateway integrations.
How to Choose the Right System
The right answer to which systems support automated email marketing depends on three factors: your business model, your existing tech stack, and the automation complexity you need.
| Business type | Best-fit platform |
|---|---|
| B2B or SaaS | HubSpot, ActiveCampaign |
| Ecommerce (Shopify/WooCommerce) | Klaviyo, Omnisend |
| Small business or creator | Kit, MailerLite, Brevo |
| Enterprise | Salesforce Marketing Cloud, HubSpot Enterprise |
| High-volume senders | Brevo |
| Budget-constrained teams | MailerLite, Brevo |
Marketing automation software users can benefit from a 451% increase in qualified leads. But that result only follows from picking a system your team will actually use and configure correctly. Most platforms offer free trials. Test two to three options with real campaigns before committing.
Whichever system you choose, the fundamentals still determine results. If you're evaluating where to invest your email marketing energy, start with the areas where the data shows the largest performance gaps: automation, deliverability, and personalization. Strong email list segmentation strategies and personalized content amplify whatever automation system you put in place.
