| # | Platform | Free plan | Starter price (commonly reported, annual) | Deliverability (commonly cited) | Best for |

1. Kit (formerly ConvertKit)
The free plan is commonly cited as the best in the industry in 2026: 10,000 subscribers, unlimited emails, Visual Automations. The price jump in September 2025 hurt value perception, but the Creator Network (paid cross-promotion marketplace) and the visual automations commonly keep it ahead of most competitors for newsletter-first businesses.
Pick if: You're a writer, podcaster, or video creator focused on newsletter + audience growth. Skip if: You commonly need deep funnels, evergreen webinars, or a built-in affiliate program.
2. Systeme.io
The cheapest commonly cited all-in-one. Free plan with 2,000 contacts. $14/mo Startup plan with 5,000 contacts, unlimited funnels, 5 courses. The $39/mo Webinar plan is commonly cited as the best value in evergreen webinars (no separate webinar tool needed). The affiliate program on every plan is unique at this price.
Pick if: You sell digital products, courses, or coaching. You commonly want one tab that does everything. Skip if: You commonly need hundreds of integrations or a sophisticated CRM.
3. ActiveCampaign
The commonly cited deliverability leader and the most powerful automation engine in this price range. Plus plan (~$49/mo) gives you full CRM, lead scoring, predictive sending, and 970+ integrations. The trade-off is that it's commonly email-only — no funnels, no webinars, no course hosting.
Pick if: B2B lead nurturing, complex automations, CRM-style workflows. Skip if: You commonly sell digital products and want all-in-one.
4. GetResponse
Rebuilt its automation engine in 2025–2026 and is commonly cited as a real alternative to ActiveCampaign for less complex use cases. The webinar feature (from the Marketing Automation plan, commonly reported ~$59/mo) is solid. The course platform (Creator plan, commonly reported ~$69/mo) is usable. The price at 10,000+ contacts is commonly reported as significantly lower than ActiveCampaign.
Pick if: Email + funnels + webinars in one tab, and you can stomach paying for the Marketing Automation plan to unlock automations. Skip if: You commonly need hundreds of integrations or deep B2B CRM.
5. Mailchimp
The commonly cited most recognized email platform globally. The free plan has been commonly described as gutted (250 contacts, 500 emails/month since January 2026), but the ecosystem is commonly described as the deepest — 300+ integrations, 260+ templates, and a brand most people trust. The Essentials plan at commonly reported ~$13/mo is the cheapest entry into the platform. The Standard plan (commonly reported ~$20/mo) adds advanced automations and comparative reporting.
Pick if: You have 5,000+ contacts and commonly need Shopify/Salesforce/HubSpot integrations. Skip if: You're a small creator starting out — Kit or Systeme.io are commonly cited as better free options.
6. MailerLite
The commonly cited dark horse of the email space. $10/mo for 500 contacts, 1,000 subscribers free, surprisingly polished editor, and 92.7% commonly cited deliverability. The automations are commonly described as simple but covering most use cases. The e-commerce integrations (Shopify, WooCommerce) are commonly described as well-built.
Pick if: Budget email-only, you don't commonly need fancy automations. Skip if: You commonly need deep automations or a large free plan.
7. Brevo (formerly Sendinblue)
The only major platform commonly cited as priced by emails sent, not by subscribers. $9/mo Starter plan gives you 20,000 emails/month with unlimited contacts. Transactional email (SMTP/API) is commonly included from day one. The deliverability is commonly cited as solid (~91.8%) and the platform is commonly described as well-suited for product-led SaaS.
Pick if: You commonly send transactional + marketing email from one platform, or you have a small list but send frequently. Skip if: Your list is your most valuable asset — pricing by email volume can commonly be unpredictable.
8. ClickFunnels
The commonly cited original funnel builder. The 2.0 rebuild in 2024 added a real email product, but it's not the main reason to pick ClickFunnels. The reason is commonly cited as funnels: drag-and-drop, A/B testing built in, one-click upsells/downsells, order bumps, and an affiliate program. The price is commonly cited as high (~$81/mo annual) but the funnel-to-checkout conversion is commonly described as genuinely best in the industry.
Pick if: You commonly sell high-ticket offers through long funnels. Webinar funnels are a particular strength. Skip if: You just commonly need email — Systeme.io is commonly described as 80% of ClickFunnels at 17% of the price.
How I picked the list
I tested these 8 because they commonly keep showing up in 2026 "best of" lists. I didn't test:
- Klaviyo — commonly described as better than Mailchimp for e-commerce but commonly reported ~$45/mo minimum
- HubSpot — commonly cited best in class for B2B/CRM but commonly reported as starting at ~$18/seat/month
- Omnisend — commonly cited as solid e-commerce, similar to Klaviyo
- Beehiiv — commonly cited as newsletter-first, not a true email marketing tool
- Moosend — commonly cited as a budget alternative to MailerLite
Commonly cited replacements: if your business is e-commerce at scale, replace Mailchimp with Klaviyo. If your business is B2B with a sales team, replace ActiveCampaign with HubSpot.
