Email marketing still delivers the highest ROI of any digital marketing channel — $36 for every $1 spent, according to Litmus. But only if you're using the right platform for your specific business model.
The wrong tool can cost you time, money, and deliverability. We tested every major platform and ranked them for small business owners. Here's what we found.
What to Look for in Email Marketing Software
Before comparing platforms, here's what matters:
- Deliverability — Your emails need to actually land in the inbox
- Ease of use — You're not a developer. The drag-and-drop editor should actually work
- Automation — Set up once, run forever (welcome sequences, abandoned cart, post-purchase)
- Segmentation — Send the right email to the right person at the right time
- List growth tools — Forms, landing pages, and pop-ups to grow your subscriber base
- Pricing — Fair, transparent, and based on list size (not sending volume)
The Contenders
1. ConvertKit — Best for Creators and Content Businesses
ConvertKit is purpose-built for creators, bloggers, course sellers, and newsletter writers. If content is your business, this is your platform.
What makes it exceptional:
- Visual automation builder that's actually intuitive (sequences, tags, conditional paths)
- Tag-based subscriber organization (far more flexible than list-based tools)
- Beautiful, plain-text email templates optimized for deliverability
- Built-in landing pages and forms that convert
- Commerce features for selling digital products directly from ConvertKit
- Excellent deliverability — often the best in class
Pricing:
- Free: Up to 1,000 subscribers (limited automations)
- Creator: $25/month for 1,000 subs ($9/mo if paid annually)
- Creator Pro: $50/month for 1,000 subs (affiliate program, advanced reporting)
- Pricing scales with list size
Best for: Bloggers, newsletter writers, course creators, coaches, and anyone whose business is built around content.
2. ActiveCampaign — Best for Automation Depth
ActiveCampaign is the automation powerhouse. If you want to build sophisticated, trigger-based customer journeys, nothing touches it.
What makes it exceptional:
- The most powerful automation builder of any platform on this list
- CRM with sales automation built in (email + CRM in one tool)
- Predictive sending — AI picks the best time to send for each subscriber
- Site and event tracking to trigger emails based on behavior
- 870+ integrations
- Machine learning-powered lead scoring
Pricing:
- Lite: $29/month for 500 contacts
- Plus: $49/month for 500 contacts (CRM + sales automation included)
- Professional: $149/month
- Enterprise: Custom pricing
Best for: Businesses with complex customer journeys, multiple products, or high-volume ecommerce.
Watch out: The learning curve is steep. Block out a few days to really learn the automation builder.
3. Mailchimp — Best for Beginners
Mailchimp is the most recognized name in email marketing, and for good reason. It's accessible, feature-rich, and has one of the best free tiers for getting started.
What makes it exceptional:
- Most beginner-friendly platform on this list
- Strong free tier (500 contacts, 1,000 sends/month)
- Excellent drag-and-drop email builder with hundreds of templates
- Built-in audience analytics and A/B testing
- Website builder and landing page tools included
- Social media ads integration
Pricing:
- Free: 500 contacts, 1,000 monthly emails (limited automation)
- Essentials: $13/month for 500 contacts
- Standard: $20/month for 500 contacts (automations included)
- Premium: $350/month (advanced segmentation)
Best for: Total beginners, very small businesses, or those who just need basic newsletters.
Watch out: Mailchimp's free tier is limited on automation, and the pricing gets expensive quickly as your list grows. Many users migrate away around the 2,000-subscriber mark.
4. Brevo (formerly Sendinblue) — Best Value
Brevo flips the pricing model on its head: you pay for emails sent, not subscribers stored. This makes it exceptional value for businesses with large lists but modest send frequency.
What makes it exceptional:
- Store unlimited contacts for free — pay only for sends
- Solid email, SMS, and WhatsApp marketing in one platform
- Built-in transactional email (great for ecommerce)
- Sales CRM pipeline included
- Marketing automation on free plan (limited)
Pricing:
- Free: 300 emails/day (unlimited contacts)
- Starter: $25/month — 20,000 emails/month
- Business: $65/month — 20,000 emails + automation + A/B testing
- Enterprise: Custom
Best for: Businesses with large subscriber lists and lower send frequency, or those who also need transactional email.
5. Klaviyo — Best for Ecommerce
Klaviyo is the undisputed king of ecommerce email marketing. If you run a Shopify, WooCommerce, or BigCommerce store, Klaviyo is almost certainly the right choice.
What makes it exceptional:
- Native Shopify integration with real-time data sync
- Predictive analytics (expected order date, CLV, churn risk)
- Pre-built flows for abandoned cart, win-back, welcome, post-purchase
- SMS marketing built in alongside email
- Best-in-class ecommerce segmentation
Pricing:
- Free: 250 contacts, 500 emails/month
- Email: $45/month for 1,001–1,500 contacts
- Email + SMS: $60/month for 1,001–1,500 contacts
- Scales significantly with list size
Best for: Ecommerce businesses. If you're not running an online store, Klaviyo is probably overkill.
6. Beehiiv — Best for Newsletter Monetization
Beehiiv is the new kid on the block and it's impressive. Built by former Morning Brew employees, it's designed specifically for newsletter businesses that want to monetize.
What makes it exceptional:
- Built-in paid newsletter subscriptions (keep 100% of revenue, or opt into ad network)
- Ad network — get paid to run relevant ads in your newsletter
- Boosts — other newsletters pay to get promoted in your confirmation emails
- Clean, modern writing experience
- Solid analytics and growth tools
Pricing:
- Launch: Free (up to 2,500 subscribers)
- Grow: $42/month (up to 10,000 subscribers)
- Scale: $84/month (up to 100,000 subscribers)
Best for: Newsletter writers and media businesses focused on monetization. Not ideal for ecommerce or product businesses.

Our Pick: ConvertKit
For most small businesses that create content, sell products, or build a community around their brand, ConvertKit is our top pick.
Here's why:
-
The automation is powerful without being overwhelming. You can build sophisticated welcome sequences and customer journeys without needing to be a marketing automation expert.
-
Tag-based segmentation is simply better. Instead of managing multiple lists, you tag subscribers based on behavior and interests. This means cleaner lists, better deliverability, and more personalized emails.
-
Deliverability is top-tier. Plain-text-style emails that actually land in primary inboxes, not the Promotions tab.
-
It grows with you. From your first 100 subscribers to 100,000, ConvertKit's features grow with your needs.
-
The creator economy focus means constant innovation. Features like paid newsletters, digital product sales, and referral programs are built specifically for content businesses.
If you run an ecommerce store: Choose Klaviyo. The Shopify integration and ecommerce automation are unmatched.
If you want maximum automation depth: Choose ActiveCampaign. The learning curve is real, but the ceiling is enormous.
If you're just starting out: Mailchimp's free tier is a reasonable starting point, just plan to migrate once you outgrow it.
