What This Stack Does
The Email Marketing Stack helps you build, grow, and monetize an email list from scratch. Email is still the most profitable marketing channel — with an average ROI of $36 for every $1 spent — and AI makes it dramatically easier to write emails that people actually open, read, and click.
This stack covers the full lifecycle: creating lead magnets to attract subscribers, writing welcome sequences that build trust, sending weekly newsletters that keep your audience engaged, and crafting promotional emails that drive affiliate sales or product launches. AI handles the heavy writing, while you focus on strategy and building genuine relationships with your audience.
The beauty of email marketing is that your list is an asset you own. Unlike social media followers, your email subscribers can't be taken away by an algorithm change. Every subscriber you add is building long-term, compounding value.
The bottom line: An email list is the single most valuable digital asset you can build. This stack gives you the tools to grow it faster, write better emails, and monetize it sooner — all for $54/mo (or just $20/mo while you're under 1,000 subscribers).
The Tools
Three tools, three jobs. Here's exactly what each one does in this stack and why it earns its spot.

The Weekly Workflow
This weekly workflow is designed to grow your list while consistently delivering value to existing subscribers. Follow this process and you'll add 50-100+ new subscribers per week while monetizing through affiliate offers and your own products.
Plan & Create Lead Magnet Content
Review subscriber growth and engagement metrics in ConvertKit. Identify which topics got the most opens and clicks last week. Use ChatGPT to brainstorm a new lead magnet idea or improve an existing one. Create or update a PDF checklist, template, or mini-guide in Canva. Set up the landing page and delivery automation.
Write Your Weekly Newsletter
Use ChatGPT to draft your weekly newsletter. Feed it your topic, key points, and tone. Generate 10 subject line options and pick the top 2 for A/B testing. Edit the draft for your personal voice — add anecdotes, opinions, and specific examples. Design a header graphic in Canva. Schedule in ConvertKit.
Build & Optimize Automations
This is your systems day. Use ChatGPT to write or improve automated email sequences: welcome series for new subscribers, nurture sequences that build trust, and promotional sequences for affiliate products or your own offers. Set up automations in ConvertKit's visual builder. Test every link and preview on mobile.
Promote & Grow
Create 3-5 social media posts promoting your lead magnet and newsletter using Canva for graphics and ChatGPT for captions. Share in relevant communities, forums, and groups. Engage with comments and DMs. Consider cross-promotions with other newsletter creators in adjacent niches.
Analyze & Monetize
Review the week's performance: new subscribers, open rates, click rates, and revenue. Identify best-performing content and double down. Research new affiliate products that align with your audience's needs. Update your monetization strategy and plan next week's content focus.
Get This Stack
Everything you need to start your email marketing side hustle:
Just $20/mo while under 1K subscribers (ConvertKit is free). One affiliate email to an engaged list can pay for months of tools.
Income Potential
Email marketing has one of the highest ROIs of any side hustle because you own the audience and can monetize through multiple channels. Here's what's realistic at different stages:
Months 1–3: Building
$0–$300/moFocus on creating your first lead magnet, setting up automated sequences, and growing to your first 500-1,000 subscribers. Early income comes from affiliate links in your welcome sequence and newsletters. The key metric is engagement, not list size.
Months 3–6: Growing
$300–$1,500/moYour list hits 1,000-3,000 subscribers. Affiliate income becomes consistent. You start landing small sponsorship deals. Your automated sequences are refined and converting well. You might launch your first small digital product.
Months 6–12: Scaling
$1,500–$3,000+/moWith 3,000-10,000+ engaged subscribers, revenue compounds from multiple sources: affiliate partnerships, sponsorships, your own digital products or courses, and potentially paid newsletter tiers. A well-monetized list earns $1-$3 per subscriber per month.
Who This Stack Is For
Great Fit If You...
- Want to build an audience asset you own (not dependent on social media algorithms)
- Have expertise in a specific niche people want to learn about
- Can commit to emailing your list consistently (at least weekly)
- Like the idea of building systems that earn while you sleep
- Want to monetize through affiliates, sponsorships, or your own products
- Are a blogger, course creator, or coach who needs a nurture system
Not Ideal If You...
- Want instant results — building a profitable list takes 2-4 months of consistent work
- Are unwilling to write regularly (AI helps enormously but you still need to show up)
- Want purely service-based income (see the Freelance Writer Stack)
- Plan to spam or sell without providing genuine value first
- Don't have a clear niche or topic area to build around
Common Questions
You can start earning with as few as 500 engaged subscribers. The key metric is engagement, not list size. A list of 1,000 subscribers with 40% open rates will outperform a list of 10,000 with 5% open rates. Focus on attracting the right people, not the most people.
ConvertKit is purpose-built for creators and makes automation dead simple. Its visual automation builder, tagging system, and landing pages are significantly better for this use case. Mailchimp works but its free plan has limitations that quickly become frustrating. ConvertKit's free plan is generous enough to get you started and grow to 1,000 subscribers.
The best lead magnets solve a specific, immediate problem. Checklists, templates, and swipe files work best because they offer instant utility. A "10-Step Checklist for X" will always outperform a "Complete Guide to Everything." Keep it focused, actionable, and under 5 pages. Use ChatGPT to outline it and Canva to make it look professional.
At minimum, once per week. Consistency matters more than frequency. If you email every Tuesday, your audience learns to expect and look forward to it. Going silent for weeks and then blasting promotions is the fastest way to kill your list. AI makes weekly emails easy — the hardest part is just showing up.
Raw AI output often does. That's why editing is essential. Use ChatGPT to generate the structure and key points, then inject your personality, stories, and specific opinions. The best newsletters feel like a smart friend talking to you — AI gives you the foundation, and you add the human element that makes people hit reply.
