10 Best Email Marketing Platforms, Software, Tools

Email marketing software is still effective in reaching and engaging customers in 2025.

We spent the last few weeks testing the 10 best email marketing platforms, software, and tools to prove this.

We assessed them based on their feature set, pricing, and user experience. 

While each had its unique selling point, Mailchimp stands out with its comprehensive feature set.

At SMB Guide, we have evaluated email marketing software for years. Our goal is to offer accurate info to help you make informed decisions when picking one for your business. 

Mailchimp is our pick because of its all-in-one marketing hub, affordable entry plan pricing, and user-friendliness. However, Mailchimp has complications with data migration.

1. Mailchimp – Editors choice
2. ActiveCampaign – Best for marketing automation
3. Kit – Best for creators
4. Constant Contact – Best for email marketing
5. Klaviyo – Best for ecommerce brands

How we evaluate and test apps

When I’m testing apps/tools, I employ a dual approach based on free trial availability. For platforms offering free trials, I test their functionalities, usability, navigation, and ease of use. In the case of software lacking a free version or trial, I rely on in-depth research and user testimonials through software review platforms like G2, Capterra, and TrustRadius to gauge their performance and capabilities.
