Best Email Marketing Tools for Affiliate Marketers in 2026 — Honest, No-Fluff Comparison

TheReviewLabs.run.place  ·  Updated April 2026  ·  12 min read

Bottom Line Up Front: The best email marketing tools for affiliate marketers in 2026 are Kit (best free plan — 10,000 subs free), GetResponse (best for serious funnels), and MailerLite (best budget option). But the most important thing to know first: not all platforms allow affiliate marketing — and if you pick the wrong one, you can lose your account. This guide tells you exactly which tools allow it, which don’t, and which one you should start with depending on your setup.

I want to start with something most comparison posts skip over entirely.

When I was setting up email marketing for this blog — promoting ClickBank, JVZoo, and WarriorPlus products — I nearly signed up for Mailchimp because everyone kept recommending it. Then I found out Mailchimp bans affiliate marketing outright. You build your list, put in weeks of work, and one day your account just gets terminated because you dropped an affiliate link in a broadcast.

That would have been a disaster.

So before we even get into features and pricing, let me make sure you don’t make that mistake. Not every platform is built for what we’re doing. The best email marketing tools for affiliate marketers are the ones that explicitly allow what we’re doing — and ideally pay us to recommend them too.

I’ve tested or closely reviewed all five tools below. Here’s the honest breakdown.

1. The Affiliate Marketing Email Problem Nobody Talks About

⚠️ Important Before You Sign Up Anywhere: Mailchimp, HubSpot (free tier), and several other popular platforms have strict anti-affiliate-marketing policies. Sending emails with affiliate links through these platforms can get your account suspended — sometimes without warning. Always check a platform’s Acceptable Use Policy before building your list there.

Here’s the breakdown of which major platforms allow affiliate marketing and which don’t:

Now that we’ve established which tools are safe to use, let’s compare the five platforms that actually work for affiliate marketers.

3. Kit (ConvertKit) — Best Email Marketing Tool for Affiliate Bloggers OUR TOP PICK

Kit (formerly ConvertKit)

Best for: Affiliate bloggers & content creators

🆓 Free plan: Up to 10,000 subscribers

💰 Paid from: $29/month (1,000 subs)

🤝 Affiliate policy: Allowed (70–80% own content rule)

💸 Their affiliate commission: 50% recurring, 12 months

This is the tool I use for this blog and the one I recommend to most affiliate marketers who are running a content site. Here’s why.

The free plan is genuinely one of the best in the industry. Kit gives you up to 10,000 subscribers completely free — including unlimited broadcasts, unlimited landing pages, and unlimited opt-in forms. Compare that to GetResponse’s 500-contact free plan or AWeber’s 500-contact limit, and it’s not even close. For a new affiliate blogger who’s building from scratch, this means you can grow your list for months before spending a single dollar on email marketing.

The email editor is deliberately minimal. There are no flashy HTML templates, no drag-and-drop image-heavy designs. Kit’s emails are clean and text-based — and that’s actually a feature, not a limitation. Text-based emails feel personal. They look like a message from a friend, not a marketing newsletter. And for affiliate marketing specifically, personal emails convert far better than polished ones.

Kit’s Automation: Simple but Effective

Setting up a welcome sequence in Kit takes about 20 minutes once you know what you’re doing. You create a “sequence,” write your emails, set the delay between each one, and attach it to any form or landing page. Every new subscriber goes through it automatically. That’s it. No complex workflow diagrams, no conditional branching unless you want it.

The tagging and segmentation system is where Kit gets genuinely clever. You can tag subscribers based on which links they click — so someone who clicks your ClickBank link gets tagged “interested in ClickBank” and you can send them targeted follow-ups. This kind of simple segmentation used to require paid tools. Kit does it on the free plan.

The Affiliate Marketing Condition — What It Actually Means

Kit’s terms say your emails should be at least 70–80% your own original content, not pure affiliate promotion. In practice, this means: if you’re a blogger sending content + occasional product recommendations, you’re completely fine. If you’re trying to use Kit purely as an affiliate broadcast machine with no original content at all — that’s when you’d run into issues.

For the audience on this blog — people building genuine affiliate content sites — Kit is 100% appropriate.

✅ What We Love

• 10,000 subs free — best in class
• Text emails that feel personal and convert well
• Simple, clean automation setup
• Smart tagging and segmentation
• Built-in landing pages (no extra tool needed)
• 50% affiliate commission for 12 months

❌ Limitations

• Template library is very minimal
• Paid plans get expensive at scale (5k+ subs)
• No built-in sales funnel builder
• 70–80% own-content condition requires a real blog

Bottom line on Kit: If you’re running an affiliate blog and want to start free, grow organically, and not worry about hitting a free-plan ceiling for months — start with Kit. It’s what we use. Sign up for Kit free here.

4. GetResponse — Best Email Marketing Tool for Serious Affiliate Funnels

GetResponse

Best for: Advanced funnels & heavy automation

🆓 Free plan: 500 contacts (limited features)

💰 Paid from: $15/month (1,000 contacts)

🤝 Affiliate policy: Fully supported

💸 Their affiliate commission: 40–60% recurring, 12 months

Of all the platforms in this comparison, GetResponse is the most openly affiliate-friendly. They have a dedicated “affiliate marketing” page in their documentation. They list it as a legitimate use case. There are no conditions, no “70–80% own content” rules — you can promote affiliate offers as aggressively as you want within normal email best practices.

The automation is where GetResponse genuinely beats Kit. The visual workflow builder lets you create sophisticated sequences based on subscriber behaviour — if they click link A, they go down path 1; if they don’t open within 3 days, they get a follow-up. This kind of conditional automation is powerful for affiliate promotions where you want to follow up with people who showed interest but didn’t buy.

GetResponse Beyond Email

GetResponse isn’t just an email tool. It includes landing page builders, sales funnel templates, webinar hosting, and conversion funnels all built in. If you’re planning to build out product launch sequences for ClickBank offers — the kind where you warm up your list for a week before dropping the offer — GetResponse has the infrastructure to do that properly.

According to EmailVendorSelection’s independent review, GetResponse’s contact scoring feature is particularly useful for affiliates — you can score subscribers based on engagement and focus your promotions on the highest-intent segment of your list rather than blasting everyone equally.

The Affiliate Program — Worth Knowing

GetResponse’s affiliate program pays 40% recurring commission for 12 months, scaling up to 60% once you hit volume. That 90-day cookie duration is genuinely useful — someone who clicks your link today and signs up in two months still counts as your referral. If you’re creating content about email tools, GetResponse is one of the highest-paying programs you can promote.

✅ What We Love

• No restrictions on affiliate marketing
• Best-in-class visual automation builder
• Landing pages, funnels, webinars all included
• Contact scoring helps target high-intent subs
• 40–60% affiliate commission, 90-day cookie
• Time-optimised sending (AI picks best send time)

❌ Limitations

• Free plan caps at 500 contacts
• Can feel overwhelming for complete beginners
• Advanced features require higher-tier paid plans

Bottom line on GetResponse: If you’re serious about building affiliate funnels — not just a simple welcome sequence but actual multi-step campaigns around product launches — GetResponse is the better long-term tool. Try GetResponse free here.

5. MailerLite — Best Budget Email Marketing Tool for Affiliate Marketers

MailerLite

Best for: Budget-conscious affiliates just starting out

🆓 Free plan: 1,000 subscribers, 12,000 emails/month

💰 Paid from: $9/month (1,000 subs)

🤝 Affiliate policy: Allowed

💸 Their affiliate commission: 30% lifetime recurring

MailerLite is the one I’d recommend to someone who genuinely has a tight budget and wants a clean, easy tool to get started. The free plan gives you 1,000 subscribers and 12,000 email sends per month — more than enough for a new affiliate blogger’s first six months.

The interface is genuinely the cleanest of the five tools here. The email builder is drag-and-drop with a decent template library. Automation is simpler than GetResponse but covers the basics — welcome sequences, link-based triggers, and basic conditional logic.

Where MailerLite wins is price. Once you hit the paid tier, it’s the cheapest of the five options at $9/month for 1,000 subscribers. And their affiliate program pays 30% lifetime recurring — meaning unlike Kit and GetResponse which cap at 12 months, MailerLite keeps paying you as long as your referral stays subscribed. That could add up to significantly more over 2–3 years.

✅ What We Love

• Cleanest, easiest interface of any tool here
• Cheapest paid plan ($9/mo)
• 30% lifetime recurring affiliate commission
• Good landing page builder included
• Solid deliverability

❌ Limitations

• Free plan limited to 1,000 subs (vs Kit’s 10,000)
• Automation less powerful than GetResponse
• No webinar or sales funnel tools built in
• Payout minimum of $100 before you can withdraw affiliate earnings

Bottom line on MailerLite: Great second choice if Kit’s 70–80% own-content condition feels too restrictive for your use case, and you want something cheap and simple. Try MailerLite free here.

6. Brevo — Best Email Marketing Tool for High-Volume Affiliate Senders

Brevo (formerly Sendinblue)

Best for: High-volume senders on a tight budget

🆓 Free plan: Unlimited contacts, 300 emails/day

💰 Paid from: $9/month (20,000 emails)

🤝 Affiliate policy: Allowed (case-by-case review)

💸 Their affiliate commission: Fixed CPA per paid referral + $5/free signup

Brevo has an unusual pricing model that makes it interesting for affiliates with larger lists. Instead of charging by number of subscribers, they charge by number of emails sent per month. That means you can have an unlimited number of contacts on the free plan — the cap is 300 emails per day, not 300 contacts.

If you have a large, relatively inactive list — for example, 10,000 subscribers but you only email them once a week — Brevo could be significantly cheaper than Kit or GetResponse on a paid plan. The maths changes depending on your sending volume, so it’s worth running the numbers for your specific situation.

The automation and segmentation are solid for the price. Multi-channel marketing (email + SMS + WhatsApp) is built in, which isn’t something the other tools here offer at this price point. For most pure affiliate email marketers this isn’t needed, but it’s worth knowing about.

✅ What We Love

• Unlimited contacts even on free plan
• Cheapest option for large lists with moderate send volume
• Multi-channel (email + SMS + WhatsApp)
• Good transactional email tools

❌ Limitations

• 300 emails/day cap on free plan = too slow for broadcasts to big lists
• Affiliate commission structure less generous than Kit/GetResponse
• Case-by-case review for affiliate accounts (can cause delays)

Bottom line on Brevo: Situationally useful if you have a large list and low send frequency. Not the first choice for most affiliate bloggers starting out.

7. AWeber — Reliable, Affiliate-Friendly, Good for Template Lovers

AWeber

Best for: Beginners who want more visual email templates

🆓 Free plan: 500 subscribers, 3,000 emails/month

💰 Paid from: $15/month (500 subs)

🤝 Affiliate policy: Explicitly allowed

💸 Their affiliate commission: 30–50% lifetime recurring

AWeber has been around since 1998 and is one of the original affiliate-friendly email platforms. They’ve explicitly welcomed affiliate marketers for years, long before it was standard practice. If you’re looking for a platform with a long track record of not banning affiliate accounts, AWeber has that.

The template library is the biggest, offering over 600 pre-designed email templates. If you want visually polished newsletters with images and branded layouts (rather than Kit’s plain text approach), AWeber has the best selection here.

The free plan is more limited than Kit — only 500 subscribers and 3,000 emails per month. And the pricing at scale is higher than MailerLite or Brevo. But the affiliate program is one of the better ones: 30% starting commission scaling up to 50% based on referral volume, with a 365-day cookie duration — the longest of any tool on this list.

✅ What We Love

• Long track record of being affiliate-friendly
• 600+ email templates
• 365-day cookie duration on affiliate program
• Good for visual, HTML-style newsletters
• Reliable deliverability

❌ Limitations

• Free plan limited to 500 subscribers
• More expensive than MailerLite and Brevo at scale
• Interface feels dated compared to newer tools

Bottom line on AWeber: A solid, trustworthy choice for affiliate marketers who want visual templates and don’t mind paying a bit more. Not our top pick, but reliable. Try AWeber free here.

8. Final Verdict: Which Is the Best Email Marketing Tool for Affiliate Marketers?

Here’s our honest “who should pick what” breakdown:

Our overall recommendation: start with Kit. The 10,000-subscriber free plan gives you the most runway. The simplicity means you’ll actually set it up and use it rather than getting lost in features. And the 50% affiliate commission means you can genuinely earn recurring income by recommending it honestly to your own audience.

If you find yourself needing more powerful funnel tools as you grow — migrate to GetResponse. The migration is straightforward (export your list as CSV, import into GetResponse), and by the time you need those features, you’ll likely have revenue to justify the upgrade.

💡 Important: Whichever tool you choose, sign up for their affiliate program too. You’re going to recommend email tools to your audience anyway — recommending the tool you actually use, with your affiliate link, is one of the easiest recurring income streams available to an affiliate blogger. Kit pays 50% for 12 months. GetResponse pays up to 60%. MailerLite pays 30% forever. Pick your tool, use it, and get paid to recommend it.

Frequently Asked Questions — Best Email Marketing Tools for Affiliate Marketers

What is the best free email marketing tool for affiliate marketers?

Kit is the best free option in 2026 — it allows up to 10,000 subscribers completely free, including unlimited broadcasts, landing pages, and forms. The next best free option is MailerLite at 1,000 subscribers free. Avoid Mailchimp’s free plan — they ban affiliate marketing in their terms of service.

Does Mailchimp allow affiliate marketing?

No. Mailchimp’s acceptable use policy explicitly restricts affiliate marketing. Using Mailchimp to send emails with affiliate links is against their terms and can result in account termination without warning. Use GetResponse, Kit, MailerLite, Brevo, or AWeber instead — all of which are affiliate-friendly.

Which email marketing tool has the best affiliate program?

For immediate earning potential, Kit and GetResponse are best — both pay high recurring commissions for 12 months. For long-term passive income, MailerLite and AWeber pay lifetime recurring commissions that never expire. GetResponse has the highest potential ceiling at 60% recurring if you generate high volume.

Can I use Kit (ConvertKit) for ClickBank affiliate marketing?

Yes, as long as affiliate promotions don’t make up the majority of your emails. Kit’s guideline is that your own content should represent 70–80% of what you send. If you’re running an affiliate blog and recommending products as part of genuine content — which is exactly what this site does — Kit is completely fine. The issue would only arise if you were using Kit purely as a promotional broadcast tool with no original content at all.

What’s the cheapest email marketing tool for affiliate marketing?

MailerLite is the cheapest at $9/month for 1,000 subscribers on a paid plan. Brevo can be cheaper than that if you have a large list but low send frequency, since they price by emails sent rather than contacts stored. Kit is free for up to 10,000 subscribers, which makes it the cheapest option of all for lists under that size.

Is GetResponse worth it for affiliate marketing beginners?

If you’re a complete beginner, start with Kit (free) or MailerLite (cheap) first. GetResponse’s power becomes most valuable when you’re ready to build multi-step funnels and landing page sequences around product launches. Once you’re generating consistent traffic and building your list actively, upgrading to GetResponse makes sense. Starting there on day one is overkill — you’ll pay for features you won’t use yet.
