There's something deeply wrong with the email marketing industry: most tools are either overpriced dinosaurs or half-baked startups that disappear after a year. We tested 18 platforms over 3 months to find the 5 that actually deliver. No fluff, no "in today's digital landscape" nonsense — just the tools we'd actually put our own business on.
| Rank | Tool | Best For | Price From | Free Tier |
|---|---|---|---|---|
| #1 | MailerLite | Best overall value | $13/mo | 1k subscribers |
| #2 | Brevo | Multi-channel & growth | $9/mo | 300 emails/day |
| #3 | ConvertKit | Creators & course sellers | $25/mo | 1k subscribers |
| #4 | Mailchimp | Design & beginners | $13/mo | 500 contacts |
| #5 | Klaviyo | E-commerce stores | $20/mo | 250 contacts |
#5 — Klaviyo: E-Commerce Powerhouse
Best for: Online stores and DTC brands that live by email revenue.
Klaviyo is the gold standard for e-commerce email — deep Shopify/WooCommerce integration, predictive analytics, and pre-built flows for every shopping scenario. But it's expensive and overkill if you don't run a serious online store. Free: 250 contacts. Paid from $20/mo.
💡 Use it if: You're on Shopify and email drives 20%+ of your revenue. Otherwise it's too much tool for too much money.

#4 — Mailchimp: The Familiar Face
Best for: Small businesses sending newsletters with beautiful templates.
Mailchimp is still the most beginner-friendly email platform. The free plan (500 contacts) is decent, and the template library (100+) is unmatched. But post-Intuit acquisition, pricing has crept up and the free plan keeps shrinking. It's being squeezed from below by MailerLite/Brevo and from above by Klaviyo/ActiveCampaign.
⚠️ Use it if: You want the best drag-and-drop builder and don't mind paying a premium for it. But honestly, MailerLite's builder is 90% as good for half the price.

#3 — ConvertKit: Creator's Choice
Best for: Authors, course creators, and content businesses.
ConvertKit (now Kit) is purpose-built for creators. The tag-based system is powerful for audience segmentation. Free plan: 1k subscribers. Creator plan ($25/mo) unlocks subscriber scoring. The plain-text focus is intentional — personal emails convert better than polished newsletters for most creators.
🔑 Use it if: You sell courses, memberships, or digital products. The tag system alone makes it worth considering over the alternatives.

#2 — Brevo: The Smart Money
Best for: Price-sensitive businesses that want email + SMS in one platform.
Brevo (formerly Sendinblue) offers the best value in email marketing. Free plan: 300 emails/day. Paid from $9/mo (5k emails, no contact limit). Built-in SMS, WhatsApp, and chat. Pricing is volume-based, making it ideal for growing lists. Deliverability is excellent and automation is genuinely advanced on the Starter plan.
🏆 Use it if: You're bootstrapped, growing fast, and want multi-channel from day one. The contact-limit-free pricing model is the most fair in the industry.

#1 — MailerLite: Best Bang for Buck
Best for: Small businesses wanting professional emails at the lowest price.
MailerLite offers the best price-to-feature ratio in email marketing. Free: 1k subscribers, 12k emails/mo. Business ($13/mo) removes all limits. Drag-and-drop builder, automation, landing pages, and a basic CRM — all at a fraction of competitors' prices. It's not the flashiest tool, but it's the one we recommend most often.
🥇 Use it if: You want the best value for money. It's that simple. For 90% of small businesses, MailerLite is the right choice.

Bottom Line
If you pressed us to recommend one tool for a random small business, it'd be MailerLite. It does everything well, costs almost nothing, and you'll never outgrow it before you outgrow your business model. If you need SMS and multi-channel from day one, Brevo is the smarter choice. If you run an online store, Klaviyo is worth the premium.
