Why Email Marketing Still Has the Highest ROI
Every year, marketers debate which channel deserves the most attention. Social media gets the headlines. SEO gets the conference talks. Paid ads get the budgets. But email marketing quietly delivers the best return on investment of any channel — and it is not close.
The numbers are stark: for every $1 spent on email marketing, small businesses earn an average of $36–$42 back. No other channel comes close. Social media averages $2.80 per dollar. Paid search hovers around $2. Display ads barely break even for most small businesses.
The reason is ownership. Your email list is yours. When Instagram changes its algorithm, your organic reach drops to 2%. When Google rolls out a core update, your traffic can vanish overnight. But your email list? Nobody can take that away. You hit send, and your message lands in inboxes. Open rates for small business emails average 30–40% — compare that to 1–5% organic reach on social platforms.
The catch: you need the right tool. A bad email marketing platform will cost you time, deliverability, and eventually subscribers. A good one will grow with your business for years.
We tested the seven most popular email marketing tools for small business and compared them on pricing, ease of use, automation capabilities, deliverability, and value for money. Here is what we found.
Quick Comparison
| Tool | Best For | Free Tier | Paid From | Automation | Ease of Use |
|---|---|---|---|---|---|
| Kit | Creators | 10,000 subs | $29/mo | Excellent | Excellent |
| Mailchimp | Beginners | 500 subs | $13/mo | Good | Excellent |
| Brevo | Value | 300 emails/day | $9/mo | Excellent | Good |

#1 Kit (formerly ConvertKit) — Best for Creators
Kit has earned its reputation as the go-to email tool for creators, and the 2026 version cements that position. The platform is built around a subscriber-first model: instead of organizing emails into lists and campaigns, you manage one unified subscriber base with tags, segments, and automations layered on top.
This matters because it eliminates the duplicate subscriber problem that plagues list-based tools like Mailchimp. If someone signs up through your blog and your landing page, they are one subscriber, not two — which means you are not paying double.
The visual automation builder is intuitive without being simplistic. You can create sophisticated sequences that branch based on subscriber behavior: which emails they opened, which links they clicked, which products they purchased. For creators selling digital products, Kit's built-in commerce features (sell ebooks, courses, and paid newsletters directly) eliminate the need for a separate platform like Gumroad.
Kit's free plan is remarkably generous — 10,000 subscribers with unlimited landing pages and forms. The catch is that automations and sequences require the Creator plan ($29/month). But if you are just getting started, the free tier lets you build a meaningful audience before you need to pay anything.
Pros
- 10,000 free subscribers — most generous free tier
- Tag-based system prevents duplicate charges
- Visual automation builder
- Built-in commerce for digital products
- Excellent deliverability rates
- Creator-focused community and support
Cons
- Free tier has no automation sequences
- Email template designs are intentionally minimal
- No built-in A/B testing on free plan
- $29/mo starting price is higher than some competitors
#2 Mailchimp — Best Free Tier for Beginners
The name everyone knows — and the easiest way to send your first email campaignMailchimp is the default choice for a reason: it is the easiest email marketing tool to pick up and use. The drag-and-drop editor is genuinely good. The template library is extensive. And the onboarding walks you through everything from importing contacts to sending your first campaign.
If you have never sent a marketing email before, Mailchimp will get you from zero to "campaign sent" faster than any other tool on this list. The free plan includes 500 contacts, 1,000 sends per month, basic segmentation, and a surprisingly capable landing page builder.
The downside? Mailchimp has become expensive. As your list grows past the free tier, the pricing escalates quickly. At 5,000 subscribers, you are paying $75/month for the Standard plan. At 10,000, it is $110/month. Competitors like MailerLite and Brevo offer similar features at a fraction of the cost.
Mailchimp also counts unsubscribed contacts toward your subscriber limit unless you manually archive them. This is a frustrating gotcha that inflates your costs as your list ages.
Pros
- Best onboarding experience for beginners
- Polished drag-and-drop email editor
- Huge template library
- Strong integration ecosystem (300+ apps)
- Built-in basic CRM
Cons
- Free plan limited to 500 contacts
- Gets expensive quickly as list grows
- Counts unsubscribed contacts in your total
- Automation is clunky compared to Kit or GetResponse
- Phone support only on Premium ($350+/mo)
#3 Brevo (formerly Sendinblue) — Best Value
Pay by email volume, not subscriber count — the most affordable option for growing listsBrevo's pricing model is its killer feature. While every other platform on this list charges based on how many subscribers you have, Brevo charges based on how many emails you send. You can have 100,000 subscribers and still be on a $9/month plan, as long as you are only sending a few campaigns per month.
For businesses that send a monthly newsletter plus occasional promotions, this model saves serious money. A business with 10,000 subscribers sending two emails per month would pay $9/month on Brevo versus $79+/month on Mailchimp.
Brevo is also one of the most full-featured platforms in this space. Beyond email, it includes SMS marketing, WhatsApp campaigns, live chat, a CRM, and transactional email — all in one dashboard. If you want a unified customer communication platform, Brevo is hard to beat on value.
The trade-off is that Brevo's email editor is not as polished as Mailchimp's, and the interface has more of a learning curve. The free plan also adds Brevo branding to your emails, which looks unprofessional.
Pros
- Volume-based pricing saves money for large lists
- Unlimited contacts on all plans
- Includes SMS, WhatsApp, chat, and CRM
- Strong automation workflows
- Transactional email included
Cons
- Brevo branding on free plan emails
- Email editor is functional but not beautiful
- Free plan capped at 300 emails per day
- Steeper learning curve than Mailchimp
#4 GetResponse — Best Automation
The most powerful automation engine for small businesses that want to sell on autopilotIf your goal is to build sophisticated marketing automation — welcome sequences, abandoned cart recovery, lead scoring, webinar funnels — GetResponse has the most capable automation engine in this price range.
The visual workflow builder lets you create branching automations based on dozens of triggers: email opens, link clicks, page visits, purchases, tag applications, custom field changes, and more. You can build multi-step funnels that would require Zapier and three separate tools on other platforms.
GetResponse also includes features you will not find in most email tools: built-in webinar hosting (up to 1,000 attendees), conversion funnels with pre-built templates, and a website builder. For a solopreneur or small team running an online business, it can genuinely replace four or five separate subscriptions.
The free plan gives you 500 subscribers with unlimited newsletters, one landing page, and a website builder. The Email Marketing plan at $19/month unlocks autoresponders, basic segmentation, and A/B testing. The Marketing Automation plan at $59/month is where the real power lives: full automation workflows, webinars, sales funnels, and advanced segmentation.
Pros
- Most powerful automation builder in this price range
- Built-in webinar hosting
- Conversion funnels with templates
- Website builder included
- Good deliverability and support
- AI-powered email subject line generator
Cons
- Full automation requires $59/mo plan
- Interface can feel overwhelming at first
- Template designs are dated compared to Mailchimp
- Free plan limited to 500 contacts
#5 MailerLite — Best for Simplicity
Clean, fast, and affordable — the underrated choice that does everything you actually needMailerLite is the tool we recommend most often to small business owners who just want email marketing to work without complexity. The interface is clean and fast. The email editor is excellent. The pricing is some of the most affordable in the industry.
The free plan includes 1,000 subscribers, 12,000 emails per month, 10 landing pages, a website builder, and signup forms. Paid plans start at just $10/month for 500 subscribers and scale linearly — 5,000 subscribers costs $39/month, 10,000 costs $73/month. That is roughly half what Mailchimp charges.
MailerLite also nails the basics that matter most: high deliverability, fast loading emails, clean templates, and responsive customer support. The automation builder is capable enough for most small business needs: welcome sequences, drip campaigns, date-triggered emails, and behavior-based workflows.
Where MailerLite falls short is in advanced features. If you need deep CRM integrations, complex conditional logic in your automations, or native e-commerce features, you will outgrow it. But for 90% of small businesses, MailerLite does everything you need at a price that is hard to beat.
Pros
- Extremely clean, fast interface
- Affordable pricing at every tier
- 1,000 free subscribers
- Excellent email deliverability
- Built-in website and landing page builder
- 24/7 email support even on free plan
Cons
- Strict approval process for new accounts
- Limited advanced automation logic
- No built-in CRM
- Fewer integrations than Mailchimp
#6 Beehiiv — Best for Newsletters
Built by the team behind Morning Brew — purpose-built for newsletter creators who want to grow fastIf your primary goal is building a newsletter audience rather than selling products, Beehiiv is the platform designed exactly for that use case. Built by the team behind Morning Brew (a newsletter that grew to millions of subscribers), Beehiiv includes growth-focused features that traditional email tools simply do not offer.
The standout features: a referral program that rewards subscribers for sharing your newsletter, a recommendation network that cross-promotes you with other Beehiiv newsletters, built-in monetization through paid subscriptions and an ad network, and web-hosted archives that turn your newsletter into a blog with zero extra effort.
The writing experience is also superb. Beehiiv's editor is fast, distraction-free, and supports rich formatting without wrestling with drag-and-drop blocks. If you are a writer, this matters more than you might think.
The trade-off: Beehiiv is not a traditional email marketing tool. It has minimal automation, no CRM, and limited e-commerce features. If you need to send product promotions, abandoned cart emails, or complex drip sequences, look elsewhere. But for newsletter creators who want to grow and monetize an audience, Beehiiv is the best platform available in 2026.
Pros
- Built-in referral program for growth
- Recommendation network cross-promotion
- Monetization via paid subs and ad network
- Beautiful, fast writing experience
- Web-hosted newsletter archives
- Free plan supports 2,500 subscribers
Cons
- Not designed for product marketing
- Minimal automation capabilities
- $49/mo jump from free to paid is steep
- No CRM or e-commerce features
#7 Buttondown — Best for Developers
Markdown-first, API-driven, and minimalist — the email tool that gets out of your wayButtondown is the anti-Mailchimp. It is intentionally minimal, opinionated, and built for people who write in Markdown, care about clean HTML output, and want an API they can actually build on.
The editor accepts Markdown natively and produces clean, lightweight emails that render perfectly across all clients. There is no drag-and-drop builder, no stock photo library, no template gallery. You write words, Buttondown sends them. If that sounds limiting, this tool is not for you. If it sounds liberating, you have found your platform.
The API is first-class. You can programmatically manage subscribers, send emails, query analytics, and build custom integrations. Buttondown also supports paid subscriptions (powered by Stripe), RSS-to-email, and custom domains.
Buttondown is built and maintained by a single developer, Justin Duke, and it shows in the best way: the product is fast, the design is clean, updates are frequent, and support is personal. The free tier is limited to 100 subscribers, and paid plans start at $9/month for up to 1,000 subscribers.
Pros
- Markdown-first editor with clean HTML output
- Excellent, well-documented API
- Lightweight, fast, no bloat
- Paid newsletter support via Stripe
- RSS-to-email automation
- Ethical, indie-built software
Cons
- Free tier limited to 100 subscribers
- No visual email builder
- Minimal automation features
- Not suited for e-commerce or product marketing
- Smaller support team (solo developer)
How to Choose the Right Email Marketing Tool
With seven strong options, the "best" tool depends entirely on your situation. Here is a decision framework to cut through the noise:
Start with your primary use case
"I want to sell products or services via email" → Kit or GetResponse
"I want to send a regular newsletter" → Beehiiv or Buttondown
"I just need basic email marketing" → MailerLite or Mailchimp
"I need maximum features for minimum cost" → Brevo
Consider your budget
If you are bootstrapping and every dollar counts, start with a free tier. Kit's free plan (10,000 subs) is the most generous for creators. MailerLite's free plan (1,000 subs) is the best all-around free option. Mailchimp's free plan (500 subs) is the easiest starting point for absolute beginners.
Think about where you will be in 12 months
The tool you pick now should still work when your list is 10x bigger. Switching platforms is annoying — you lose your automation workflows, email templates, and sometimes deliverability reputation. If you expect rapid growth, pick a tool with pricing that scales well. Brevo's volume-based pricing and Kit's tag-based system both handle growth better than Mailchimp's escalating per-subscriber costs.
Evaluate deliverability
The best email is worthless if it lands in spam. Kit, MailerLite, and GetResponse consistently rank highest in independent deliverability tests. Mailchimp has seen deliverability complaints increase since its Intuit acquisition, though it remains adequate for most users.
Free vs. Paid: When to Upgrade
Every tool on this list offers either a free plan or a free trial. Here is when it actually makes sense to start paying:
Stay Free When...
- Your list is under 1,000 subscribers
- You send basic newsletters or broadcasts
- You don't need automation sequences
- You are testing whether email marketing works for your business
- Budget is your primary constraint
Upgrade When...
- You hit the subscriber or send limit
- You need automation (welcome sequences, drip campaigns)
- You want to remove platform branding from emails
- You need A/B testing to optimize performance
- Email is generating measurable revenue for your business
A good rule of thumb: once email is generating revenue, it can pay for its own tools. If your email list drives even one sale per month, a $10–$30/month email tool pays for itself many times over. Do not cheap out on the tool that talks directly to your customers.
If you are a creator or solopreneur, our recommendation is to start with Kit's free plan — the 10,000 subscriber limit gives you plenty of room to grow before you need to pay. When automation becomes critical to your workflow, Kit's $29/month Creator plan or GetResponse's $19/month plan both deliver excellent value.
Frequently Asked Questions
Mailchimp offers the most beginner-friendly free tier, with 500 contacts and 1,000 sends per month plus a drag-and-drop editor. MailerLite is a strong alternative with 1,000 free subscribers and a cleaner interface. If you are a creator or blogger, Kit offers a free plan for up to 10,000 subscribers, though automations are locked to the paid tier. For the largest free email volume, Brevo lets you send 300 emails per day to unlimited contacts.
Most platforms charge based on subscriber count. At 1,000 subscribers, expect $0–$29/month. At 5,000 subscribers, costs range from $29–$59/month. At 10,000 subscribers, you are looking at $59–$99/month. Brevo is the exception: it charges by email volume instead of subscriber count, which can cut costs dramatically if you send infrequently. All seven tools in this guide offer either a free tier or a free trial, so you can test before you commit.
Absolutely. Email marketing delivers an average ROI of $36–$42 for every $1 spent — higher than any other marketing channel. Unlike social media, you own your email list. Algorithm changes cannot reduce your reach to zero overnight. Email open rates for small businesses average 30–40%, compared to 1–5% organic reach on social platforms. If you run a business and are not building an email list, you are leaving money on the table.
Yes. Every reputable platform lets you export your subscriber list as a CSV file, which you can import into another tool. You keep all email addresses, names, and custom fields. What you may lose are automation workflows, email templates, and historical analytics — these do not transfer between platforms. To minimize disruption, set up your new platform fully before canceling the old one, and send a test campaign to confirm deliverability before switching.
Traditional email marketing tools (Mailchimp, Kit, GetResponse) are designed for businesses that want to send promotional emails, drip sequences, and automated workflows to drive sales. Newsletter platforms (Beehiiv, Buttondown) are optimized for content creators who want to build an audience around regular written content — they often include paid subscriptions, referral programs, and web-hosted archives. The line is blurring, but your primary goal determines the right choice: selling products means email marketing, building a media brand means newsletter platform.
