Building an affiliate email funnel with ConvertKit is the most reliable way to turn one-time blog traffic into recurring affiliate commissions. While most affiliates focus entirely on getting ranked content, the ones who build consistent income have one thing in common: a list. ConvertKit is purpose-built for creators and content marketers, and its combination of affiliate-friendly terms, visual automation builder, and clean broadcast editor makes it the go-to platform for affiliates who want to grow a subscriber base and monetise it systematically. This guide walks you through every step of building a fully functional affiliate email funnel convertkit setup — from your first opt-in form to your first automated promotional sequence. If you’re still deciding between platforms, see my ConvertKit vs ActiveCampaign comparison before reading on.
- What this covers: A complete affiliate email funnel build in ConvertKit — from opt-in form and landing page through lead magnet delivery, automated nurture sequence, promotional broadcasts, and subscriber segmentation.
- Time to set up: 2–3 hours for a fully functional funnel (form, landing page, 5-email welcome sequence, one broadcast template, and basic tagging).
- What you need first: An active ConvertKit account (free plan works), a lead magnet (PDF checklist, mini-course, or resource list), and 2–3 affiliate offers to promote in your sequence.
What Is an Affiliate Email Funnel? (And Why ConvertKit?)
An affiliate email funnel is a structured sequence of emails designed to move a new subscriber from “just joined your list” to “ready to buy through your affiliate link.” Unlike a one-off promotional email, a funnel warms up subscribers over several emails — delivering value, building trust, and introducing affiliate offers at the right moment in the right context.
ConvertKit is the right platform for this because it was built specifically for creators who sell and promote products through content. Its automation builder lets you create tag-based sequences that respond to subscriber behaviour — so a subscriber who clicks your affiliate link for a particular tool gets tagged and added to a more targeted follow-up sequence, while someone who doesn’t click gets a different nurture path. That kind of intelligent sequencing used to require expensive enterprise tools. ConvertKit puts it on the free and starter plan.
The core components of an affiliate email funnel in ConvertKit are: (1) an opt-in form connected to a landing page or embedded in your site, (2) an automated welcome and nurture sequence that delivers your lead magnet and introduces your affiliate offers, (3) broadcast emails for time-sensitive promotions, and (4) a tagging system that segments subscribers by interest so you can target the right offers to the right people. Let’s build each one.
Step 1: Create Your ConvertKit Account and Set Up Your Domain
Start at app.convertkit.com and create your account. The free plan supports up to 1,000 subscribers and includes unlimited broadcasts and one automated sequence — enough to build and test your first funnel before paying anything. Once you’re in, the first configuration step is connecting your custom sending domain.
Navigate to Settings → Email and look for the “Custom Sending Domain” section. Enter your domain (for example, mail.yourdomain.com) and follow the DNS verification steps. ConvertKit will give you a CNAME record to add in your domain registrar. This step is critical for deliverability — emails sent from a verified custom domain land in the inbox at significantly higher rates than those sent from a shared ConvertKit subdomain. Allow 24–48 hours for full DNS propagation.
While you’re in Settings, also configure your From Name and Reply-to Email. Use your own name or brand name, and set the reply-to to an address you actually monitor. ConvertKit subscribers who reply to your emails are your most engaged audience — you don’t want those conversations going to a dead inbox.
Step 2: Build Your Opt-in Form and Landing Page
Navigate to Landing Pages & Forms → Create New. ConvertKit gives you two options: an embeddable form (placed in your website sidebar, footer, or within content) and a hosted landing page (a standalone URL that ConvertKit hosts for you). For most affiliates, you’ll want both — an embedded form for your blog posts and a standalone landing page to use in social media profiles and paid campaigns.
For your opt-in form, choose a template that matches your site’s design and set the headline to communicate the specific value of your lead magnet. The single highest-impact optimisation you can make to an opt-in form is specificity in the headline. “Get my free guide” underperforms every time compared to “Get the 7-tool AI affiliate stack that earns $3k/month” — because the second version makes the outcome concrete. Keep the form to a single field (email only) to maximise conversions.
For your landing page, use the same specificity principle, add 3–5 bullet points that describe what your subscriber gets, and include a short credibility sentence about you or your site. Landing pages in ConvertKit are mobile-responsive by default. Once published, ConvertKit gives you a hosted URL — share this anywhere you want to grow your list outside your blog.
Step 3: Create Your Lead Magnet Delivery Sequence
Navigate to Automations → Sequences → New Sequence and create your lead magnet delivery email. This is Email 1 in your welcome sequence, sent immediately after someone subscribes. Its job is to deliver the lead magnet, confirm the subscriber made the right decision, and set expectations for what comes next.
Structure your lead magnet delivery email as follows: (1) a warm, brief welcome that confirms what they signed up for; (2) the direct download link or access URL for your lead magnet; (3) a one-sentence preview of what the next email will cover; (4) a P.S. line that introduces yourself and links to your most popular blog post. This structure achieves two things — it delivers on the promise immediately, and it creates forward momentum that keeps open rates high on Email 2 and beyond.
Upload your lead magnet to a reliable host — Google Drive, Dropbox, or your own website. Avoid hosting it directly in ConvertKit, as links can expire if you change plans. Test the delivery email yourself by subscribing to your own form before going live.
Step 4: Build Your Automated Welcome and Nurture Sequence
Your welcome sequence is the highest-leverage automation in your entire funnel. New subscribers are at peak engagement immediately after joining — open rates on Email 1 typically run 60–80%, dropping to 30–40% by Email 3–5. This means the first five emails in your sequence are where you build the relationship that determines whether a subscriber eventually buys through your affiliate links or unsubscribes.
A high-performing 5-email affiliate welcome sequence follows this structure: Email 1 — lead magnet delivery + welcome (sent immediately); Email 2 — your biggest insight or framework (sent day 1); Email 3 — a tool or resource recommendation with affiliate link context (sent day 3); Email 4 — a case study or before/after story (sent day 5); Email 5 — direct affiliate offer with a clear call to action (sent day 7). Each email should have a single focus and a single CTA — multi-offer emails consistently underperform single-offer emails in affiliate sequences.
Writing five emails that sound natural and not salesy is the hardest part of this process. AI writing tools significantly speed up the drafting process — my Jasper AI affiliate marketing tutorial covers exactly how to use AI to write email sequences that convert without sounding like they were generated by a robot. The key is to use AI for first drafts and structure, then edit each email in your own voice before scheduling.
In ConvertKit, set each email’s send timing as “days after subscribing” in the sequence editor. Set a subject line for each email before saving — ConvertKit won’t allow you to activate a sequence with unsaved subject lines. Once all five emails are written, connect the sequence to your opt-in form by navigating to Automations → Visual Automations → New Automation, selecting “Subscribes to a form” as the trigger, and adding your sequence as the action.
Step 5: Set Up Your First Affiliate Promotional Broadcast
Once your automated welcome sequence is live, you have a functioning base funnel. The next layer is broadcast emails — one-time sends to your full list (or targeted segments) for product promotions, launch campaigns, and seasonal affiliate offers.
Navigate to Broadcasts → New Broadcast. ConvertKit’s broadcast editor is intentionally minimal — plain text with optional images, a subject line, and a preview text field. This minimalism works in your favour for affiliate promotions: plain-text emails consistently outperform heavily designed HTML emails in open rate and click-through rate for affiliate products, because they read like personal emails rather than advertisements.
Structure your first promotional broadcast as: (1) a relevant observation or question that connects to your subscriber’s pain point; (2) a transition that introduces the affiliate product as a solution; (3) 3–5 specific benefits (not features) of the product; (4) your affiliate link with a clear CTA (“click here to try it free”, “see current pricing”, etc.); (5) a P.S. line that repeats the single most compelling benefit. Before sending, preview the broadcast on mobile — the majority of email opens happen on mobile, and a link that’s hard to tap will kill your click rate.
Set up your broadcast’s sending time using ConvertKit’s send time optimisation, or manually select a Tuesday–Thursday morning send window (9–11am in your subscribers’ primary timezone), which consistently produces the highest open rates for content-driven affiliate lists.
Step 6: Tag Subscribers and Segment for Targeted Promotions
Tagging is what separates a basic email list from a true affiliate marketing funnel. ConvertKit’s tag-based system lets you label subscribers based on their behaviour — which links they click, which forms they submitted, which sequences they completed — and then use those tags to send highly targeted follow-up campaigns.
Set up behaviour-based tagging in your visual automation: when a subscriber clicks a link in Email 3 (your tool recommendation), apply a tag like “interested-in-[tool-name]”. Then create a separate follow-up sequence triggered by that tag — 2–3 emails that go deeper on that specific tool’s use case, addressing common objections, and presenting your affiliate link again. This targeted follow-up approach routinely doubles click-through rates compared to blasting the same offer to your full untagged list.
In ConvertKit, tags are created inside sequences and broadcasts using the “Link Actions” feature: click the link icon on any URL you insert, select “Add a tag when clicked”, and create or select the relevant tag. The tag is applied automatically when a subscriber clicks that link — no manual work required after setup. Build your tag library incrementally: one tag per affiliate product category (email tools, SEO tools, AI writing tools, etc.) gives you clean segments to target with relevant promotions from day one.
Advanced Tips: Optimising Your ConvertKit Affiliate Funnel for More Clicks
1. A/B test subject lines on broadcasts. ConvertKit’s built-in A/B testing sends two subject line variants to a small portion of your list, then automatically sends the winner to the rest. Run A/B tests on every broadcast with 10,000+ subscribers. For smaller lists, keep a manual log of subject line patterns — curiosity-based subjects vs benefit-based vs question-based — and track which categories get higher open rates over time.
2. Use text-based affiliate links, not banner images. Plain hyperlinked text consistently outperforms image-based affiliate banners in email. “Click here to start your free trial” beats a product banner in click-through rate in virtually every affiliate email test. If you must include an image, make sure it’s also a clickable link.
3. Leverage AI for email copy variations. Writing multiple subject line variants and CTA options manually is time-consuming. Tools like Jasper and Copy.ai (see my Copy.ai vs Jasper AI breakdown) generate five subject line options in seconds and can produce entire email drafts from a single-sentence brief. Use them to produce first drafts, then edit for your specific voice and audience.
4. Segment by engagement level. Create a “cold subscribers” segment of anyone who hasn’t opened an email in 90 days and run a re-engagement campaign (3 emails, increasing urgency, last email is a “we’re removing you” notice) before removing them from your list. A clean, engaged list gets better deliverability than a large, unengaged one — and ConvertKit’s pricing is based on subscriber count, so removing cold subscribers saves you money.
5. Align your email content with your ranked posts. Your highest-traffic SEO content should feed directly into your email funnel. If a post about SEO tools ranks well and drives traffic, build a lead magnet specifically for that post’s audience and an automated sequence that promotes your top SEO tool affiliate offers. The tighter the alignment between what someone searched for, what they read, and what your email sequence promotes, the higher your conversion rate. My Surfer SEO content workflow guide covers the content ranking side of this system in detail.

Final Thoughts: Your ConvertKit Affiliate Funnel Is Ready
At this point you have the complete infrastructure of a working affiliate email funnel: an opt-in form collecting subscribers from your blog, a landing page for off-site list growth, a 5-email automated welcome sequence that delivers your lead magnet and introduces affiliate offers, a broadcast workflow for recurring promotions, and a tagging system that segments subscribers by interest for targeted follow-up campaigns. This is the same core setup that powers the affiliate email operations of some of the most profitable content sites in the creator economy.
The next step is iteration. Over the first 30 days, watch your open rates, click rates, and unsubscribe rates. A welcome sequence open rate below 40% on Email 1 usually means your subject line or from-name isn’t connecting — test both. A click rate below 2% on your affiliate offer emails usually means the offer isn’t resonating with your audience or your copy isn’t creating enough desire — consider testing a different offer or rewriting the email from a different angle. The funnel you build today is a starting point, not a finished product.

FAQ: Building an Affiliate Email Funnel with ConvertKit
How many emails should be in an affiliate welcome sequence?
A 5–7 email welcome sequence is the sweet spot for most affiliate marketers. Five emails gives you enough touchpoints to deliver your lead magnet, build credibility, and introduce your primary affiliate offer without overwhelming new subscribers. Some high-volume affiliates run 10–14 email sequences for complex or higher-ticket offers, but for most email affiliate funnels a 5-email sequence is the right starting point. The most important rule is that every email should earn the next one — if an email in your sequence doesn’t add value or create curiosity about the next, cut it or rewrite it.
Can I promote multiple affiliate products in one ConvertKit funnel?
Yes, and you should — but introduce one product per email rather than multiple products in the same email. A typical approach is to mention your primary affiliate product in Email 3, a secondary complementary product in Email 5, and then use ConvertKit’s tag-based segmentation to follow up with more targeted sequences based on which links subscribers click. This keeps each email focused and prevents the “pitch fatigue” that comes from heavy multi-product promotions early in a relationship. As your list grows, you can run separate automations for different product categories targeting tagged segments.
How do I avoid spam filters when sending affiliate emails in ConvertKit?
The most important steps are: (1) verify your sending domain in ConvertKit settings — authenticated custom domains dramatically reduce spam filter hits; (2) avoid spam trigger words in subject lines (free, guaranteed, cash, urgent, act now, etc.); (3) maintain a clean list by removing subscribers who haven’t opened in 90+ days; (4) always include a clear unsubscribe link (ConvertKit adds this automatically); (5) never purchase or import email lists — only send to subscribers who explicitly opted in through your ConvertKit forms. ConvertKit’s platform-level sender reputation is strong, and following these practices will keep your deliverability high.
What is a good open rate for affiliate email campaigns in ConvertKit?
For welcome sequence emails (automated), open rates of 50–70% on Email 1 and 35–50% on Emails 2–5 are strong benchmarks. For broadcast promotional emails, a 25–40% open rate is considered good for a healthy engaged list in the creator/affiliate space. Click-through rates on affiliate offer emails typically run 2–6% of opens for well-targeted offers. If your open rates are below 25% on broadcasts, focus on list hygiene (remove cold subscribers) and subject line testing before anything else. Open rate is your leading indicator — if people aren’t opening, nothing in the email body matters.
How long does it take to build an affiliate email funnel in ConvertKit?
A complete basic funnel — opt-in form, landing page, 5-email welcome sequence, and basic tagging automation — takes 2–3 hours to build if you have your lead magnet ready. The breakdown is roughly: 30 minutes for account setup and domain verification, 30 minutes for form and landing page design, 60–90 minutes for writing and scheduling your 5 welcome emails, and 30 minutes for setting up the visual automation that connects your form to your sequence. The lead magnet is typically the longest part of the whole process — if you don’t have one yet, budget an additional 2–4 hours to create a simple PDF checklist or resource list that’s genuinely useful to your target audience.
