Picking the right email marketing automation platform is a pricing decision as much as a features decision. Email marketing delivers an average return of $36 for every dollar spent, so even a modest difference in monthly platform costs can significantly shift your net ROI over time. The problem is that most platforms bury their real costs inside tiered contact limits, automation restrictions, and feature gates that only appear after you sign up.
This guide cuts through that. It compares the most widely used email marketing automation pricing plans across budget, mid-market, and enterprise tiers so you can make a precise, informed decision before committing to a contract.
Key Takeaways
- Pricing models vary significantly: Some platforms charge by contact count, others by email volume, and some by active profiles. The model matters as much as the headline price.
- Free plans have real limits: Most free tiers cap automation features, contacts, or daily sends in ways that make them unsuitable for active businesses.
- Automation depth is tier-locked: On most platforms, multi-step behavioral workflows require a mid-tier or higher plan, adding $30 to $100 per month over the base price.
- Hidden cost traps exist: Platforms like Mailchimp charge for unsubscribed and duplicate contacts; Klaviyo switched to total active profile billing in 2025, raising costs for brands with large dormant lists.
- The right tool depends on your use case: Ecommerce brands, B2B teams, and small businesses each have different needs, and the best value rarely comes from the same platform.
Why Pricing Models Matter Before You Compare Features
Before you compare email marketing automation pricing plans side by side, you need to understand how each platform counts and charges for usage. Choosing the wrong model for your list structure can double your costs.
The three main pricing models are:
- Contact-based: You pay based on the total number of subscribers in your account. Most platforms use this model.
- Email volume-based: Brevo prices by monthly email volume, not contact count, and lets you store unlimited contacts on every plan, including free. This model is significantly cheaper if you have a large list but email infrequently.
- Active profile-based: Klaviyo prices by total active profiles, meaning all subscribed contacts in your account whether emailed recently or not. Email-only at 1,000 profiles starts at $30 per month, scaling to $150 per month at 10,000 contacts. As of February 2025, Klaviyo bills on total active profiles rather than just emailed contacts, which increased costs for brands with large unengaged lists.
Understanding which model applies to your situation is the first step when you compare email marketing automation pricing plans.
Budget Tier: $0 to $20 Per Month
These platforms suit early-stage businesses, solopreneurs, and marketers with lists under 2,500 contacts who need functional automation without a large monthly commitment.
Brevo (formerly Sendinblue)
Originally a transactional email service, Brevo has evolved into a complete newsletter tool offering advanced marketing automation at a surprisingly affordable price.
The Starter plan begins at $9 per month for 5,000 emails, while Business starts at $18 per month for 5,000 emails with advanced automation. The free plan covers 300 emails per day across up to 100,000 contacts.
Brevo is the most cost-efficient option for businesses with large contact lists that send moderately. Tested inbox placement stands at 88.3% according to EmailToolTester's January 2024 round.
MailerLite
MailerLite offers email campaigns, automation, landing pages, and a generous free plan with an intuitive interface. It prices by subscriber count across three paid tiers: Growing Business ($10 per month and up), Advanced ($20 per month and up), and Enterprise (custom). At 1,000 subscribers, the Growing Business plan is $15 per month, one of the cheapest in the market.
The free plan supports 500 subscribers with 12,000 emails per month.
Mailchimp
Mailchimp is the category's default name, and increasingly the default complaint. The free plan has been cut repeatedly and is now capped at 250 contacts, with paid-tier prices rising roughly 30% over the last few years.
Multi-step automation requires the Standard plan at $20 per month minimum. A significant billing trap to watch: Mailchimp charges for unsubscribed and inactive contacts unless you manually archive them, which can inflate your bill 10 to 20% over what you would expect.
Tested inbox placement sits at 89.6% according to EmailToolTester's January 2024 round.
Mid-Market Tier: $20 to $150 Per Month
This is where the most consequential compare email marketing automation pricing plans decisions happen. Most growing businesses live here, and the feature gaps between platforms are sharpest.
ActiveCampaign
ActiveCampaign is a marketing automation powerhouse that combines email, CRM, and sales automation. It is known for its visual workflow builder with 900 or more automation templates and strong deliverability.
ActiveCampaign uses tiered pricing based on both contact count and plan level across Starter, Plus, Pro, and Enterprise. The Starter plan at 1,000 contacts is $15 per month, but most B2B teams need the Plus plan at $49 per month for 1,000 contacts to access CRM and lead scoring.
The Pro plan at $79 per month for 1,000 contacts adds predictive sending, attribution reporting, and split automation paths. Annual billing saves 20%.
For B2B teams and SaaS businesses specifically, ActiveCampaign's depth is hard to match at this price point. You can read more about applying advanced automation to SaaS growth in our guide to SaaS email marketing strategy.
Klaviyo
Klaviyo integrates deeply with Shopify, WooCommerce, and BigCommerce for behavior-based automation, predictive analytics, and revenue attribution.
Email-only plans start at $30 per month for 1,000 profiles, scaling to $150 per month at 10,000 contacts and $720 per month at 50,000 contacts.
Pricing is the biggest pain point for Klaviyo users. Costs scale quickly as lists grow and can feel disproportionate during high-growth phases. That said, Klaviyo claims its automations helped drive $14 billion in online store revenue in 2022, and many see it as the go-to platform for ecommerce marketing.
GetResponse
GetResponse offers four plans: Starter ($19 per month), Marketer ($59 per month), Creator ($69 per month), and Enterprise (custom). The Starter plan at 1,000 contacts is $19 per month, scaling to $79 per month at 10,000 contacts.
GetResponse is a versatile platform that includes webinar hosting, conversion funnels, and an AI-powered website builder, making it strong for teams that want marketing automation without enterprise pricing.
Omnisend
Omnisend offers Standard ($16 per month and up) and Pro ($59 per month and up) plans. The Standard plan at 1,000 contacts is $16 per month with email send limits of 12 times your contact count. Pro offers unlimited emails plus monthly SMS credits matching your plan cost.
Omnisend is an ecommerce-focused email and SMS marketing platform with deep Shopify, WooCommerce, and BigCommerce integrations that competes with Klaviyo at a lower price point with built-in SMS credits.
Note: EmailToolTester's January 2024 round recorded 75.1% inbox placement for Omnisend, with 21.4% landing in spam. For businesses where deliverability is critical, verify current deliverability rates before committing. 
Enterprise Tier: $150 and Above
HubSpot Marketing Hub
HubSpot sits in a category of its own because it is primarily a CRM-first platform with email marketing built in. The Professional plan starts at $890 per month for 2,000 contacts, with a monthly email sending limit of 10 times your number of active contacts.
HubSpot charges a mandatory one-time onboarding fee for new Professional and Enterprise customers. Marketing Hub Professional requires a $3,000 onboarding fee. The Enterprise plan costs $3,600 per month and includes 5 seats, with additional seats at $75 per month, 10,000 marketing contacts included, email sends at 20 times the contact tier limit per month, and a required $7,000 one-time Enterprise onboarding fee.
If you are primarily looking for an email marketing service rather than a full CRM suite, dedicated solutions like ActiveCampaign, GetResponse, and MailerLite typically deliver better value.

Hidden Costs to Audit Before You Commit
Most platform comparison guides stop at headline pricing. Here are the cost factors that regularly surprise buyers:
- Automation tier gates: Mailchimp offers no automation on the free plan, and multi-step automation requires the Standard plan at $20 per month minimum.
- Contact counting methodology: Mailchimp counts contacts across all lists. The same person in multiple audiences counts multiple times toward your limit, a policy that can inflate costs and frustrate teams.
- SMS and extra channels billed separately: ActiveCampaign charges extra for SMS, WhatsApp, and additional user seats.
- CRM features locked to higher plans: ActiveCampaign Plus at 1,000 contacts is $49 per month on annual billing. The Plus plan adds CRM, lead scoring, and landing pages, features most B2B teams consider essential.
- Onboarding fees: HubSpot's mandatory onboarding fees add $3,000 to $7,000 to the first year's cost for Professional and Enterprise customers.
Pairing your platform with the right email marketing automation CRM setup will help you avoid these traps by planning your contact structure before you migrate.
How to Choose: Matching the Platform to Your Business Type
If you are running a Shopify store doing over $10,000 per month, Klaviyo is worth the premium pricing. For service businesses and beginners, Mailchimp offers the best balance of features and affordability. Advanced marketers who need sophisticated automation should choose ActiveCampaign.
Here is a more granular breakdown:
- Early-stage or budget-constrained: Brevo or MailerLite. Both offer functional automation at under $20 per month.
- Ecommerce (Shopify/WooCommerce): Klaviyo for revenue attribution and behavioral flows; Omnisend as a lower-cost alternative with built-in SMS.
- B2B, SaaS, or complex customer journeys: ActiveCampaign. ActiveCampaign's automation builder is the most sophisticated in this category.
- All-in-one CRM plus email: HubSpot, but only if you will use the full platform. The per-contact costs at scale are among the highest in the market.
- High-volume senders with large lists: Brevo's volume-based model is dramatically cheaper if you have a large list but do not email everyone every week.
For teams building out a complete strategy, the principles behind segmentation also drive significant returns. Our guide to email list segmentation strategies shows how to structure your audience for maximum ROI regardless of which platform you choose.
The Real Cost of Getting This Decision Wrong
Email automations deliver 30 times more revenue per recipient than one-off promotional campaigns. The average return per recipient for campaigns sits at $0.11, while automated flows earn $1.94 per recipient. This difference makes automation the foundation of profitable email programs.
Choosing a platform where automation sits behind a higher plan tier, or where contact costs escalate faster than your list grows, directly erodes that ROI. Despite representing only 2% of total email volume, automated messages generated 37% of all email-attributed sales in 2024, making every automated email exponentially more valuable.
A platform that saves you $30 per month but forces manual sends instead of behavioral triggers will cost far more in lost revenue than it saves in subscription fees. Factor automation access into your total cost calculation before you commit to any plan.

Frequently Asked Questions
What is the cheapest email marketing automation platform with real automation features?
Brevo is one of the most affordable options with genuine automation. It has a free plan that provides access to automations, allowing up to 300 emails per day. The paid Starter plan begins at $9 per month for 5,000 emails, while the Business plan at $18 per month unlocks advanced automation.
Is Klaviyo worth the higher price compared to Mailchimp?
It depends on your business model. Klaviyo is purpose-built for ecommerce, with segmentation and automation tied directly to shopping behavior. For non-ecommerce businesses, the premium is harder to justify. Klaviyo is overkill for non-ecommerce businesses; you will pay for features you will not use.
What hidden costs should I watch for when comparing email marketing plans?
Watch for contact counting methodology (especially with Mailchimp's duplicate audience counting), automation tier gates, mandatory onboarding fees (HubSpot), add-on charges for SMS and extra users, and platforms that count unsubscribed contacts toward your billing tier. Some platforms include all records including unsubscribed contacts, which can inflate your billing tier unexpectedly.
At what list size should I move from a budget platform to a mid-market one?
There is no fixed threshold, but the trigger is typically complexity rather than size. If your campaigns require conditional branching, lead scoring, CRM data integration, or multi-step behavioral sequences, a budget platform will restrict you regardless of list size. Basic plans typically include email design tools, contact management, and limited automation, making them ideal for small businesses. Higher-tier plans offer advanced automation, segmentation, analytics, and integrations, making them suitable for larger or more mature operations.
