Quick comparison table

How to choose

For beginners and small businesses, Mailchimp or Brevo are the most approachable starting points. Mailchimp’s free plan and template library lower the barrier to entry, while Brevo’s volume-based pricing works well for businesses with large lists but infrequent sends.

For creators and bloggers, ConvertKit is purpose-built for the creator economy. Its tag-based system, digital product sales, and paid newsletter features address creator-specific needs that general platforms skip.

For e-commerce businesses, Klaviyo is the clear leader. Deep integrations, predictive analytics, and combined email and SMS marketing translate directly to measurable revenue.

For advanced automation, ActiveCampaign has the most capable automation engine available. Businesses with complex customer journeys, multi-step nurture sequences, or sophisticated lead scoring will get the most out of it.

For all-in-one marketing, HubSpot makes sense only if you’re adopting the broader ecosystem. Businesses already on HubSpot’s CRM and sales tools will find email a natural extension. Standalone, it’s overpriced.

1. Mailchimp

Mailchimp started as a newsletter tool and has grown into a full marketing platform. It’s still the best starting point for small businesses new to email marketing.

Drag-and-drop builder with 100+ templates, built-in marketing CRM, A/B testing, 300+ integrations. Pricing runs from free (500 contacts) to $350/mo (Premium, 10K contacts).

The free plan is genuinely useful for very early-stage businesses — 500 contacts and basic automation cover the basics. The interface is the most approachable of the six platforms here. The main weakness is automation: branching logic becomes cumbersome at any real complexity, and pricing escalates sharply as your list grows.

Best for beginners and small businesses that want an easy, familiar starting point with room to grow. Plan for the fact that you may outgrow it.

2. ActiveCampaign

ActiveCampaign is the gold standard for email automation. Its workflow builder is the most capable in this category, and its CRM integration makes it a genuine sales-and-marketing platform.

Visual automation builder with unlimited branching, CRM contact management included (sales pipeline available as an Enhanced CRM add-on), machine learning predictive sending, and dynamic content. Pricing from $15/mo (Starter) to $145/mo (Enterprise) at 1,000 contacts.

The automation depth is real — event-driven triggers, goal-based paths that adjust mid-flow, nested automations, multi-channel sequences spanning email and SMS. The visual canvas makes complex workflows manageable rather than overwhelming. The downsides: no permanent free plan, a steeper learning curve than Mailchimp, and a template editor that trails competitors in polish.

Best for businesses that need advanced automation and want marketing and sales working from the same contact record.

3. ConvertKit

ConvertKit was built specifically for creators (bloggers, podcasters, YouTubers, authors) who need to monetize an audience. Its clean interface and creator-specific features make it stand out in this niche.

Tag-based subscriber management, built-in digital product sales, paid newsletters via Stripe, landing pages, and a visual automation builder. Free Newsletter plan supports up to 10,000 subscribers. Paid plans from $9/mo (Creator) to $25/mo (Creator Pro).

The free-plan limit of 10,000 subscribers is exceptionally generous — most creators won’t pay anything for a while. Native digital product sales and paid newsletters are built in, with no third-party tools required for basic monetization. Automation is functional but deliberately limited compared to ActiveCampaign. Template options are minimal by design.

Best for content creators building and monetizing an audience through email.

4. Klaviyo

Klaviyo is purpose-built for e-commerce. Its integrations with Shopify, WooCommerce, and BigCommerce go deeper than any general-purpose platform, and revenue attribution ties every email directly to sales.

Real-time e-commerce data syncing, predictive analytics (customer lifetime value, churn risk), combined email and SMS marketing, ML-powered product recommendations, revenue attribution. Free plan covers 250 contacts. Paid from $20/mo (Email) to $35/mo (Email + SMS) at 500 contacts.

The predictive analytics are the differentiating feature: Klaviyo identifies which customers are likely to buy again, when to send for best conversion, and which segments are at churn risk, all tied to actual revenue data rather than open rates. Pricing increases significantly at larger list sizes, and it’s genuinely complex for beginners.

Best for e-commerce businesses that want email performance measured in revenue, not just opens and clicks.

5. Brevo (formerly Sendinblue)

Brevo charges by email volume rather than contact count. For businesses with large lists that send infrequently, this model is substantially cheaper than per-contact pricing.

Unlimited contacts on all paid plans, multi-channel marketing (email, SMS, WhatsApp), built-in transactional email, CRM tools, meeting scheduling. Free plan includes 300 emails/day. Paid from $9/mo (Starter, 20K emails) to $18/mo (Business, unlimited).

The pricing model is the main draw. A business with 50,000 contacts sending one campaign per month will pay far less on Brevo than on any per-contact platform. Automation is functional but limited, the template library is smaller than Mailchimp’s, and the free plan’s daily sending cap is restrictive for anything beyond testing.

Best for budget-focused businesses with large contact lists or those needing transactional email and marketing in one place.

6. HubSpot Email Marketing

HubSpot’s email module works best when it’s part of the broader HubSpot platform. Standalone, it’s expensive relative to what you get.

Full CRM integration, cross-department automation (marketing, sales, service), ad management, social media tools, multi-touch attribution reporting. Free plan includes 1,000 sends/mo. Paid from $15/mo (Starter) to $3,600/mo (Enterprise).

The cross-department automation is genuinely powerful: a single workflow can enroll a contact in an email sequence, update their CRM properties, create a sales task, and trigger a service alert. That only makes sense if you’re using all those departments in HubSpot. At Professional ($800/mo), the price is hard to justify unless the full platform is in use.

Best for businesses committed to HubSpot’s full CRM and marketing ecosystem. A poor value as a standalone email tool.

Bottom line: quick recommendations

Each platform offers a free trial or free plan. Identify your primary use case, try the top two that fit, and choose based on how the workflow actually feels to use.

Frequently asked questions

What is the best free email marketing software?

Mailchimp and ConvertKit both offer real free plans. Mailchimp supports 500 contacts with basic templates and limited automation. ConvertKit supports up to 10,000 subscribers with landing pages and basic automation — substantially more generous. For creator monetization, ConvertKit’s free plan is the better deal. For general small business use, Mailchimp’s template library and integrations offer broader utility.

How much does email marketing software cost?

Small businesses typically spend $15–100/mo. Mid-market businesses with 10,000+ contacts usually pay $100–500/mo. Enterprise organizations using HubSpot can spend $800–3,600 or more.

Which platform has the best deliverability?

ActiveCampaign, ConvertKit, and Klaviyo all report deliverability above 98%, and all three invest in email authentication, sender reputation management, and active monitoring. Mailchimp runs slightly lower (96–98%) partly due to the volume of mail it processes.
