Email marketing still delivers the highest ROI of any marketing channel — roughly $36 for every $1 spent. But choosing the right platform matters. Overpay and you're burning margin. Underpay and your emails land in spam.
We tested the most popular platforms for small businesses and ranked them on what actually matters: deliverability, ease of use, automation, and price.
In This Article
1. MailerLite — Best Overall Value
MailerLite
Clean, affordable, and surprisingly powerful for the price.
- Price: Free up to 1,000 subscribers / From $10/month (Growing Business)
- Best for: Small businesses, bloggers, anyone who wants great value
- Free tier: Yes — 1,000 subscribers, 12,000 emails/month
MailerLite flies under the radar compared to Mailchimp, but it's become the go-to recommendation in the small business community for good reason. The interface is clean and modern, the email editor is genuinely enjoyable to use, and the automation builder handles everything from welcome sequences to abandoned cart recovery.
Pros
- Excellent price-to-feature ratio
- Clean, intuitive drag-and-drop editor
- Good automation for the price tier
- Landing pages and forms included
- High deliverability rates
Cons
- Approval process can be strict (they verify your list)
- Free plan doesn't include templates
- Reporting is basic compared to ActiveCampaign
2. Kit (formerly ConvertKit) — Best for Creators
Kit
Built specifically for creators — writers, YouTubers, podcasters, and course sellers.
- Price: Free up to 10,000 subscribers / From $25/month (Creator)
- Best for: Content creators, newsletter writers, digital product sellers
- Free tier: Yes — 10,000 subscribers (limited features)
Kit (the company formerly known as ConvertKit) was built by creators, for creators. It approaches email differently — instead of designing flashy newsletters, it focuses on plain-text-style emails that feel personal. This works because creator audiences respond better to emails that feel like they're from a real person, not a marketing department.
The standout feature is the commerce integration. You can sell digital products, paid newsletters, and courses directly through Kit without needing a separate platform.
Pros
- Incredibly generous free tier (10,000 subscribers)
- Built-in commerce for digital products
- Best subscriber tagging and segmentation
- Clean, text-focused email style that converts well
Cons
- Limited visual email design options
- More expensive than MailerLite for similar features
- Not ideal for e-commerce brands that need visual emails
3. Brevo (formerly Sendinblue) — Best Free Plan
Brevo
Unlimited contacts on the free plan — pay only for emails sent.
- Price: Free (300 emails/day) / From $9/month (Starter)
- Best for: Businesses with large lists on a tight budget
- Free tier: Yes — unlimited contacts, 300 emails/day
Most email platforms charge based on subscriber count. Brevo flips this — unlimited contacts, pay per email sent. This is a game-changer if you have a growing list but only send a few campaigns per week.
Beyond email, Brevo is trying to be an all-in-one marketing suite: SMS, WhatsApp, live chat, and CRM are all built in. The email builder is solid, automation works well, and the free tier is genuinely usable for getting started.
Pros
- Unlimited contacts on free plan
- SMS and WhatsApp marketing included
- Built-in CRM
- Affordable scaling model
Cons
- Free plan includes Brevo branding
- Email editor less polished than MailerLite
- 300 emails/day limit on free plan can be restrictive
4. Mailchimp — Best for Beginners
Mailchimp
The most recognized name in email marketing — easy to start, hard to outgrow.
- Price: Free up to 500 contacts / From $13/month (Essentials)
- Best for: Complete beginners, small e-commerce stores
- Free tier: Yes — 500 contacts, 1,000 emails/month
Mailchimp is the default choice for a reason — everyone's heard of it, the onboarding is smooth, and it integrates with practically every other tool. For a complete beginner sending their first newsletter, Mailchimp makes it painless.
The problem is pricing. Once you pass 500 contacts, costs jump fast. At 5,000 subscribers, you're paying $75/month for Essentials — nearly double what MailerLite charges for similar features.
Pros
- Most beginner-friendly interface
- Huge integration ecosystem
- Good email templates
- Built-in landing pages and basic website builder
Cons
- Gets expensive quickly as your list grows
- Free plan is very limited (500 contacts)
- Charges for unsubscribed contacts unless you clean your list
5. ActiveCampaign — Best Automation
ActiveCampaign
The most powerful automation engine — for businesses ready to get serious about email.
- Price: From $15/month (Starter) | $49/month (Plus)
- Best for: Growing businesses that need advanced automation and CRM
- Free tier: 14-day trial only
ActiveCampaign is the tool you graduate to when you've outgrown MailerLite or Mailchimp. The automation builder is the best in the industry — you can create workflows that trigger based on email opens, link clicks, site visits, purchase history, lead scores, and dozens of other conditions.
The built-in CRM is also excellent. It tracks your contacts through a sales pipeline, assigns lead scores, and triggers automations based on where people are in the buyer journey. For B2B businesses or anyone with a longer sales cycle, this is incredibly valuable.
Pros
- Most powerful automation builder available
- Built-in CRM with sales pipeline
- Advanced segmentation and lead scoring
- Excellent deliverability
Cons
- No free plan — only a 14-day trial
- Steeper learning curve
- Overkill for simple newsletter needs
- Gets expensive with larger lists
