Quick comparison table

• E-commerce-focused: Klaviyo.
• Enterprise-only in practice: Salesforce Marketing Cloud Engagement.
• Bundled CRM: ActiveCampaign and Brevo.
• Free plans and trials: we did not verify free plans or trials for these tools, so every tool is marked "Paid" above. Check each vendor's site for current offers.

1. Klaviyo

Best for: e-commerce stores that want email driven by purchase data.

Klaviyo pulls real-time behavior and order data from platforms like Shopify and Magento. Its best feature is behavior-triggered flows, such as abandoned cart and browse abandonment. The catch is that it helps non-store businesses much less, and pricing scales with contact count. Available on Web, API and iOS.

2. ActiveCampaign

Best for: small and mid-sized teams that want email and CRM in one place.

ActiveCampaign comes with prebuilt automation workflows and solid segmentation. What sets it apart is multi-channel automation that goes beyond email. Plan on more setup time than you'd need with simpler tools. Available on Web, API, iOS and Android.

3. MailerLite

Best for: freelancers, creators and small teams that want a clean, simple tool.

MailerLite offers a drag-and-drop editor and a library of templates. The automation is easy and takes little learning, which is the main draw. You give up some advanced CRM and enterprise features. Available on Web and API.

4. Mailchimp

Best for: small and mid-sized businesses that want a familiar, widely used platform.

Mailchimp covers campaign builders, audience management and templates. Its broad ecosystem is the real strength, with plenty of integrations and tutorials. Costs can climb as your audience grows. Available on Web, API, iOS and Android.

5. Brevo

Best for: teams that want email, SMS and a CRM in one tool.

Brevo was formerly Sendinblue, so search the old name if that's what you know it by. It runs email and SMS campaigns with automation in a single platform. The interface covers a lot, so it can feel busy. Available on Web, API, iOS and Android.

6. Constant Contact

Best for: small businesses that want guided setup and ready-made templates.

Constant Contact includes list management tools and basic automation. Its templates and list tools are aimed at non-technical users. No API is listed, so custom integrations are limited. Available on Web, iOS and Android.

7. Salesforce Marketing Cloud Engagement

Best for: large organizations running complex customer journeys.

Salesforce Marketing Cloud Engagement is an enterprise product that fits alongside Salesforce's other products. It shines at building journeys across large, segmented audiences. For startups and freelancers it's overkill, and costly too. Available on Web and API.

8. Campaign Monitor

Best for: agencies and brands that care about polished, on-brand emails.

Campaign Monitor handles creating, sending and tracking campaigns in one place. It pairs branded email design with automation. CRM and multi-channel depth trail the leaders. Available on Web and API.
