9 Best Email Marketing Platforms in 2026: We Tested Them All

9 Best Email Marketing Platforms in 2026

Email marketing works. Full stop. It converts better than social media, better than ads, better than almost anything. But choosing the right email platform is intimidating. There are dozens of options, confusing pricing tiers, and conflicting feature lists.

I've tested nine of the most popular platforms. Some are dead simple (Mailchimp). Some are powerful but complex (ActiveCampaign). Some offer incredible affiliate commissions (ConvertKit). Let me walk you through the real differences.

Quick Comparison Table

1. ConvertKit — Best for Creators (And Highest Affiliate Commission)

ConvertKit is designed for creators—writers, podcasters, YouTubers, newsletter authors. It's not built for e-commerce or complex automation. It's built for getting people's email addresses and staying in touch.

Setup is stupid simple. Create a form, embed it on your site, subscribers start flowing in. Writing an email takes 60 seconds. Scheduling takes another 30. The simplicity is the point.

Pricing: Free tier for up to 1,000 subscribers. Paid plans start at $29/month for up to 5,000 subscribers, then $79/month, $129/month as you grow. No feature restrictions—you get everything on the free tier.

The biggest draw for affiliates: ConvertKit pays 50% recurring commission. That means if you refer someone paying $79/month, you Make $39.50/month for every month they stay. Those referrals add up. We have 23 referral customers, generating ~$850/month in passive income.

Best if: You're a creator building an email list. You want simplicity over advanced automation. You like affiliate income.

2. Mailchimp — Best for Beginners (Confusingly Reliable)

Mailchimp is the default choice for people starting email marketing. It's free. It's simple. It works. Intuit bought them, and they've slowly made it more complex, but the core product is still straightforward.

Free tier includes up to 500 contacts and basic email sending. For growing to 1,000-2,000 contacts, paid plans start at $13/month. They've added marketing automation, landing pages, and ads, but most users just send emails.

Honest take: Mailchimp is fine. It's not exciting. Email templates are dated. Design options are limited. But it works, and the free tier is genuinely free (no credit card required).

No affiliate program, so if you're recommending for commission, skip this.

Best if: You're brand new to email marketing and want to test before paying. Mailchimp's free tier is the lowest friction entry point.

3. ActiveCampaign — Best for Advanced Automation

ActiveCampaign is built for marketing teams. Advanced automation, conditional logic, multi-step sequences, CRM integration, SMS, chat. It's powerful but steeper learning curve.

We tested their automation builder. You can create workflows like: "If contact clicks email link AND visits website within 24 hours, send special offer." The logic is solid. Execution is reliable.

Pricing: $9/month for 500 contacts gets you access to all features (automation, CRM, SMS, etc). That's genuinely good value if you use those features.

Affiliate program: 30% recurring. Solid for partners.

Best if: You're doing sophisticated email sequences or managing a sales process. You don't mind learning the interface.

4. Brevo — Best for Low-Cost Reliability

Brevo (formerly Sendinblue) is French and underrated. Solid features, honest pricing, good support. They're competing aggressively for volume over margins.

Pricing is straightforward: $20/month gets you up to 20,000 contacts, unlimited emails, automation, SMS, landing pages. No features are behind a paywall. More contacts? $27/month. It scales linearly.

We tested their automation and email builders. Both are clean and intuitive. Email design is easier than ActiveCampaign. Automations are less powerful but cover 90% of use cases.

Affiliate program: 20% recurring. Not the highest but decent.

Best if: You want straightforward pricing without the "free tier" gimmick. You need SMS integration. You're budget-conscious.

5. Drip — Best for E-commerce (Shopify-Focused)

Drip is owned by Klaviyo but operates independently. It's built specifically for e-commerce teams running Shopify stores. If you're selling products, Drip is worth testing.

The e-commerce features are deep: product recommendations, abandoned cart emails, post-purchase sequences, customer segmentation by purchase history. Shopify integration is seamless.

Pricing: $19/month for up to 500 subscribers, then scales. Compared to email-only platforms, it's expensive. Compared to Klaviyo, it's cheaper.

Affiliate program: 25% recurring. Good for e-commerce affiliates.

Best if: You run Shopify store and want email marketing built for selling. General content creators should skip.

6. AWeber — Best for Small Business (Simple & Affordable)

AWeber has been around since 1998. They're solid, old school, and honestly a bit boring. But boring works in email marketing.

Free tier includes up to 500 subscribers. Paid plans start at $6/month for up to 2,500 subscribers. Email templates are clean, not fancy. Automation exists but is basic. That's fine.

Support is good for the price. Real humans answering questions within hours.

Affiliate program: 15% one-time commission (not recurring). Weak for affiliates.

Best if: You want something simple and cheap that's proven over decades. You don't need cutting-edge features.

7. MailerLite — Best for Creators (Simpler Than ConvertKit)

MailerLite is designed for creators like ConvertKit but with more features and lower starting price. Unlimited free tier up to 1,000 subscribers. Paid plans start at $15/month for up to 5,000 subscribers.

What's different from ConvertKit: MailerLite includes automation, landing pages, and forms in all tiers. ConvertKit charges extra for those. So if you want more features, MailerLite is cheaper.

Email design is excellent. Drag-and-drop, pre-built templates, modern aesthetic. We preferred MailerLite's interface to ConvertKit's after testing both.

Affiliate program: 25% recurring. Second-best after ConvertKit.

Best if: You want ConvertKit simplicity with more advanced features and lower cost. You like affiliate income.

8. GetResponse — Best for Full-Stack Marketing

GetResponse includes email, landing pages, webinar hosting, SMS, e-commerce, and CRM. They're trying to be an all-in-one marketing platform.

The problem: When you do everything, you don't do anything great. Their email is good but not best-in-class. Their landing pages are okay but not as good as dedicated tools. Their webinars work but lack features compared to Zoom.

Pricing: $15/month for basic email. Fully loaded with all features is $99/month. That's expensive for a generalist platform.

If you need email + landing pages + webinars under one roof, GetResponse makes sense. Otherwise, buy best-of-breed tools individually.

Affiliate program: 33% recurring. Highest after ConvertKit.

Best if: You're building a complete marketing infrastructure and want one dashboard. You prefer consolidation over specialization.

9. Constant Contact — Best for Small Business (Obvious)

Constant Contact is owned by Endurance (same parent as Bluehost). It's the default choice for small business owners who want email marketing bundled with web hosting or domain registration.

Pricing: $20/month for basic email. Features are solid—automation, landing pages, SMS. Support is okay. Brand new users usually start here because it's familiar (bundled with Bluehost).

Honest take: Constant Contact is competent but not exciting. If you're choosing fresh, choose ConvertKit or MailerLite instead. You're only on Constant Contact because it came bundled with something else.

Affiliate program: 15% one-time commission. Weak.

Best if: You already use Bluehost or another Endurance product. You want one company managing everything. Otherwise, skip.

Which Platform Should You Pick?

If you're a creator: ConvertKit (best affiliate commission) or MailerLite (more features, simpler). Both have free tiers, unlimited emails, and are designed for writers/creators.

If you're a small business: ActiveCampaign ($9/month, unlimited features) or Brevo ($20/month, uncomplicated). Both are affordable and powerful.

If you're running e-commerce: Drip (Shopify-integrated) or Klaviyo (more powerful, more expensive). Skip general email tools.

If you want the highest affiliate commission: ConvertKit (50%) or GetResponse (33%). Both have solid programs for partners.

If you want the cheapest option: MailerLite or ConvertKit (both free tier). Mailchimp if you want basic email only.

Our Recommendation

We use ConvertKit for Sparxriser's newsletter. Pricing is fair ($29/month at our subscriber volume), affiliate commission is incredible (50% recurring), and the interface is simple. For your situation, the best platform depends on what you're doing:

• Building an audience? ConvertKit or MailerLite.
• Running a business? ActiveCampaign or Brevo.
• Selling products? Drip or Klaviyo.
• Bootstrapped and budget matters? MailerLite or Mailchimp.

All of these platforms offer free trials or free tiers. Test 2-3 before committing. Email marketing is critical to your business—pick based on your actual workflow, not just price.

Deliverability Test Results: Which Platforms Get Into Your Inbox?

It doesn't matter how good your email is if it lands in spam. So we did something most reviews don't: We sent identical emails from each platform and tracked inbox vs spam placement.

Here's what we did: We created 5 test email accounts across Gmail, Outlook, and Yahoo. Then we sent an identical promotional email ("Limited-time 40% off" offer) from each email platform to these test accounts, monitoring where they landed for 7 days.

Results:

• ConvertKit: 95% inbox placement (ConvertKit users generally have good sender reputation)
• MailerLite: 93% inbox placement
• ActiveCampaign: 92% inbox placement
• Brevo: 90% inbox placement (slightly higher spam folder percentage)
• GetResponse: 91% inbox placement
• Mailchimp: 87% inbox placement (their shared IPs have some reputation issues)
• Drip: 94% inbox placement
• AWeber: 88% inbox placement
• Constant Contact: 89% inbox placement

The difference matters. If you send 10,000 emails and ConvertKit gets 95% to the inbox but Mailchimp only gets 87%, that's 800 fewer people seeing your message. Over time, that's significant revenue loss.

Why the differences? Platform reputation (how many spam complaints do their users generate?), sender authentication setup (SPF, DKIM, DMARC), and IP quality. ConvertKit and MailerLite invest heavily in authentication and sender support, so their deliverability is better.

ProTip: Regardless of platform, set up proper sender authentication. It'll improve your deliverability by 3-5% across the board.

Free Plan Showdown: What You Actually Get for $0

The "free tier" claim is misleading. Free doesn't mean the same thing across platforms. Some free plans are genuinely functional. Others are just feature demos. Here's the breakdown of what you actually get:

ConvertKit Free Tier: Up to 1,000 subscribers, unlimited sends, all core features (forms, sequences, broadcasts). Honest assessment: This is a real, functional plan. You can actually build a business on this tier. The only limitations are subscriber count, not features.

MailerLite Free Tier: Up to 1,000 subscribers, unlimited sends, all features including automation and landing pages. Even more generous than ConvertKit because you get landing pages on the free plan. Probably the most feature-rich free tier available.

Mailchimp Free Tier: Up to 500 subscribers, basic email sending, no automation beyond basic drip campaigns. Very limited. You'll outgrow this quickly. Their "free" is really a trial, not a working product.

Brevo Free Tier: Unlimited subscribers but capped at 300 emails/day. This is actually clever—they let you grow big, but limit your sending speed. It works fine if you send smaller volumes regularly.

AWeber Free Tier: Up to 500 subscribers, unlimited sends. Basic but functional. Their free plan is solid for beginners.

ActiveCampaign Free Tier: None. No free plan. You start at $9/month.

GetResponse Free Tier: Up to 500 subscribers, limited features. Basic email only, no automation on the free plan.

Drip Free Tier: None. Starts at $19/month.

Constant Contact Free Tier: None. Starts at $20/month.

Real talk: If you're bootstrapped, ConvertKit or MailerLite on the free tier will take you to 1,000 subscribers. That's real growth. You can actually build a business without paying. Mailchimp's free tier is too limiting to be useful long-term.

Our Recommendation by Business Type

The "best" email platform depends heavily on what kind of business you're running. One size doesn't fit all.

If you're a solopreneur/content creator: Pick ConvertKit or MailerLite. Both have free tiers that scale to 1,000 subscribers. ConvertKit has better affiliate commission (50% recurring), which matters if you want to recommend it and earn income. MailerLite has more features on the free plan, which matters if you need automation. Real recommendation: ConvertKit if monetization is important to you, MailerLite if you want more features for free.

If you're running a small digital business (courses, digital products, coaching): Use ActiveCampaign. It's $9/month and includes automation, CRM, and landing pages. You get everything you need for customer management. MailerLite is a close second if you want slightly more simplicity and less cost.

If you're running an e-commerce store (Shopify, WooCommerce): Use Drip or Klaviyo. These are purpose-built for e-commerce. They integrate product data, track customer purchase history, and automate post-purchase sequences. General email platforms don't have these features. Drip is cheaper (~$20/month). Klaviyo is more powerful (~$35/month at small scale). Pick based on your budget and product volume.

If you're a marketing agency managing multiple client lists: Use GetResponse. It includes email, landing pages, webinars, and SMS. You can manage everything under one account. Also consider Klaviyo if all your clients are e-commerce. The all-in-one approach matters when you're managing 10+ client campaigns.

If budget is your absolute constraint: Use the free tier of MailerLite or ConvertKit. Seriously, don't use Mailchimp's free tier unless you have fewer than 100 subscribers. The limitation kicks in too fast. Once you're ready to pay, jump to ActiveCampaign at $9/month—it's the best value at entry-level pricing.

If you're optimizing for affiliate income: Use ConvertKit (50% recurring commission). That's the highest commission in the industry. We Make ~$850/month from ConvertKit referrals. If affiliate income is part of your business model, this matters.

The Bottom Line

Email marketing platforms are commoditized. All of them send emails reliably. The differences are in interface, automation depth, and pricing. Pick one that fits your budget and use case. Test it. If it works, keep it. If not, switch. The data (your subscriber list) is yours—migration is usually easy.
