Choosing the right email marketing automation tools in 2025 has a direct and measurable impact on your revenue. On average, email marketing delivers a return of between $36 and $42 for every $1 spent, the highest ROI of any digital marketing channel. But not all email revenue is created equal. Automated emails drove 37% of all ecommerce email revenue in 2024 despite representing just 2% of email volume. The difference between a platform that fits your business and one that doesn't shows up fast, in time wasted, money left on the table, and contacts you never reach at the right moment.
This guide covers the top email marketing automation tools 2025, what each platform does best, who it's built for, and the data that should drive your decision.
Key Takeaways
Automated emails generate 320% more revenue than non-automated emails.
Email is the channel that relies the most on marketing automation, with 58% of surveyed professionals choosing it over both content and social media management.
The global marketing automation software market was valued at $7.23 billion in 2025 and is projected to reach $20.12 billion by 2034, at a 12% CAGR.
Marketing automation software users can benefit from a 451% increase in qualified leads.
The best tool for your business depends on your use case: B2B teams, ecommerce stores, lean startups, and high-volume senders each have different needs, and the wrong platform costs more than the right one.
Why Email Automation Matters More Now Than Ever
Email marketing automation platforms help businesses send targeted, personalized emails at scale by automating workflows, segmenting audiences, and integrating with CRM and ecommerce tools.
The scale of the opportunity is hard to ignore. Nearly 4.6 billion people used email worldwide in 2025, and that number is projected to reach 4.73 billion by end of 2026 and over 4.8 billion by 2027. Meanwhile, 58% of users say email is the first thing they check online in the morning, so a well-timed email can be the first message they see all day.
82% of marketers use automation to create triggered emails, which result in 8 times more opens and greater earnings than typical bulk emails. That gap between triggered and broadcast email performance is the core reason automation has become non-negotiable for serious email programs.
Today's marketing teams need platforms that offer predictive analytics, journey-based targeting, drag-and-drop journey builders, behavioral triggers, unified customer data for accurate segmentation, AI-powered content and optimization features, strong deliverability and compliance safeguards, and transparent pricing.
How to Choose the Right Platform
Before reviewing specific tools, get clear on your use case. The choice between platforms is rarely about features alone. It's about fit.
Key questions to answer first:
What is your list size now, and where will it be in 12 months?
Do you need a built-in CRM, or do you already have one?
Is your primary channel ecommerce, B2B, SaaS, or content?
How technical is your team?
What is your monthly budget for tooling?
To choose the best fit, map your needs by team size, use case, and required integrations.
Deliverability is a deal-breaker, and the right email marketing automation tool can get emails through spam filters. Look for platforms with automatic DKIM/SPF/DMARC prompts, bounce handling, and spam testing built in.
Pricing models also vary significantly. Most platforms offer cost-effective plans between $10 and $40 per month for small lists. The more automation and support you get, the higher the price.
Top Email Marketing Automation Tools 2025: Platform by Platform
1. ActiveCampaign: Best for Advanced Automation
For businesses requiring sophisticated marketing automation, ActiveCampaign delivers enterprise-level capabilities. Their platform excels at complex workflows and detailed customer journey mapping.
ActiveCampaign's automation builder handles intricate decision trees based on subscriber behavior, demographic data, and engagement history. ActiveCampaign offers over 1,000 integrations with various business tools, including ecommerce platforms.
ActiveCampaign won the Best Email Marketing Tool badge for 2025. Its main goal is to help you send fewer emails with better results.
Pricing: They don't offer a free plan (just a free two-week trial), but their Starter plan gives you access to multi-step marketing automation right out of the gate for only $15/month.
Best for: B2B and SaaS teams. Strong on behavioral branching, lead scoring, and lifecycle workflows.
Watch out for: Pricing increases rapidly with subscriber growth, potentially reaching $500+ monthly for larger lists.
2. HubSpot: Best for CRM-First Teams
HubSpot offers a unified platform that combines CRM capabilities with email marketing, automation, and sales tools. The streamlined data flow makes it easier to coordinate your marketing and sales efforts.
HubSpot's visual editor lets you build workflows that automate actions based on specific triggers, such as a form submission or website visit. You can create complex workflows without any coding knowledge, making it accessible to both marketers and developers.
Pricing: Starter is $15/month with 1,000 marketing contacts. Professional is $890/month with 2,000 marketing contacts and full automation workflows. Enterprise is $3,600/month with 10,000 marketing contacts.
Best for: CRM-first teams that want automation, email, and pipeline in one platform.
Watch out for: The $890/month Professional tier is where automation lives, which makes it inaccessible for smaller teams on tighter budgets. If you mostly need email automation and not full CRM, HubSpot's pricing doesn't compete with pure ESPs. The value is in the integrated platform.
3. Klaviyo: Best for Ecommerce Behavioral Segmentation
Klaviyo serves over 193,000 paying customers, including brands like Mattel, Glossier, and Liquid Death. It trades publicly on the NYSE. Its full-year 2025 revenue reached $1.2 billion, representing 32% year-over-year growth.
When it comes to automation workflows, Klaviyo stands out, with features like A/B testing directly inside flows, predictive AI tools for customer lifetime value and churn risk, dynamic segmentation, and optimized send times. It's the best choice for scaling brands that need precision and data-driven insights to fine-tune their strategy.
Klaviyo has formed a close relationship with Shopify, which owns about 11% of the company. Shopify recommends Klaviyo as the default email platform for Shopify Plus merchants.
Pricing: Klaviyo prices by total active profiles. Email-only at 1,000 profiles is $30/month, scaling to $150/month at 10K and $720/month at 50K. As of February 2025, Klaviyo bills on total active profiles rather than just emailed contacts, which increased costs for brands with large unengaged lists.
Best for: Ecommerce behavioral segmentation and predictive analytics. Klaviyo's data model is built around ecommerce events: purchase frequency, product category affinity, lifetime value tiers, and predictive next purchase date.
Watch out for: As your list grows, costs can rise quickly. The 2025 move to active profile-based billing caught many users off guard. Advanced features have a real learning curve, especially without a dedicated marketing team.
4. Brevo: Best for Value at Scale
EmailToolTester awarded Brevo the Best Email Marketing Tool for Value For Money badge in 2025 and Best Email Marketing Tool overall in 2026.
Brevo is one of the best email marketing platforms for growing businesses because it offers up to 100,000 contacts on the free plan. Paid plans are priced based on email volume rather than contact tiers, which means your costs scale with how much you actually send. The platform combines core email features, automation, and multichannel tools (SMS, WhatsApp, live chat) in one place.
Brevo's marketing automation tools are very impressive. It supports website tracking so you can trigger automated sequences from website visits. It has 12 pre-built workflow templates covering lead nurturing, abandoned carts, personalized follow-ups, and more.
Pricing: Free plan includes 100,000 contacts and 300 emails per day. Paid plans start from $18/month based on email send volume.
Best for: Budget-conscious teams that need automation without the enterprise price tag, and anyone sending both marketing and transactional email from the same platform. Brevo's volume-based pricing means unlimited contacts on the free plan, making it a strong pick for businesses with large lists but moderate send volume.
Watch out for: Brevo is weaker on CRM depth.
5. Omnisend: Best for Ecommerce Multichannel Workflows
Omnisend's email marketing software is built specifically for ecommerce stores that want to get multichannel marketing running fast, without spending weeks on configuration. Omnisend centers its features around online store workflows with pre-built automations for cart recovery, browse abandonment, and post-purchase sequences across email, SMS, and push.
Omnisend's plans run up to 35% less than Klaviyo's at comparable contact tiers, with all multichannel features included from the free plan upwards.
Pricing: Omnisend offers Standard ($16+/month) and Pro ($59+/month) plans. Standard at 1,000 contacts includes email sends at 12x your contact count. Pro offers unlimited emails plus monthly SMS credits matching your plan cost.
Best for: Beginners, solo founders, and small to mid-sized ecommerce brands looking for an affordable, user-friendly platform with multichannel capabilities.
6. MailerLite: Best for Small Businesses on a Budget
Despite its simple appearance, MailerLite supports complex automation workflows with multiple triggers and conditions. The platform's automation tools stand out particularly for their price point.

GetResponse pairs email automation with built-in webinar tools, making it one of the few platforms where you can run a live event and automatically follow up with attendees in the same system.

Deliverability: The Non-Negotiable Factor
Segmentation and automation mean nothing if your emails land in spam. If an email lands in the spam box, the chances that the recipient reads it dramatically decrease. Deliverability is a deal-breaker, and the right email marketing automation tool can get an email through spam filters.
When evaluating platforms, check for:
DKIM, SPF, and DMARC setup support
Bounce handling and list hygiene tools
Spam testing before sending
Dedicated IP options for high-volume senders
Real-time deliverability monitoring
Strong deliverability also depends on how you set up your programs, not just which platform you use. Coupling your tool choice with solid email marketing automation CRM setup practices can have a meaningful impact on your inbox placement rates.
For teams evaluating platforms, the decision usually follows: Brevo for cost-sensitive high-volume senders, ActiveCampaign for complex automation, HubSpot for CRM-first teams, and Mailchimp for simplicity on small lists.
For ecommerce teams, the best email marketing platform for behavioral segmentation is almost always Klaviyo, Omnisend, or Drip over HubSpot.
For most small and growing businesses, the practical answer is: start with a free plan, run a real campaign, and see where the friction is. Migration between platforms is manageable at small list sizes and becomes increasingly expensive at scale. Choose the platform closest to your 12-month needs, not just your needs today.
