Email Marketing from Zero: Beehiiv, ConvertKit, and Mailchimp for Founders

How to choose an email platform, build your first list, and send emails people actually open.

Email is the most underrated channel for startup founders. Social media algorithms change, SEO takes months, paid ads drain budgets. But email? You own that list. Nobody can algorithmically suppress your message. When you send an email, it lands in an inbox, and open rates for well-maintained lists still hover around 40-50%.

The problem is that most founders either never start building a list, or they choose the wrong tool and overcomplicate things. This guide covers the three email platforms worth considering, helps you pick one, and gives you the foundation to start sending emails people actually read.

Why Email Beats Every Other Channel

Here’s a number that should change your priorities: email converts at 3-5x the rate of social media traffic. A subscriber who gave you their email address has explicitly opted in. They want to hear from you. That level of intent doesn’t exist on any other channel.

Other reasons email matters:

• You own the audience. If Twitter bans your account or Instagram changes its algorithm, your email list survives.
• Direct relationship. No middleman. You send, they receive.
• Compounding asset. Every subscriber you gain stays on your list until they unsubscribe. Your audience grows monotonically.
• Cheap. The platforms are inexpensive, and marginal cost per email is essentially zero.

Beehiiv: Best for Newsletter-First Founders

Beehiiv was built specifically for newsletters and it shows. If your primary content strategy is a regular newsletter (weekly updates, industry analysis, curated links), Beehiiv is the clear winner.

What Beehiiv does well

Growth tools built in. Beehiiv includes referral programs, recommendation networks (where other newsletters recommend yours), and a web-based publication page. These features drive subscriber growth without external tools.

Monetization native. Ad networks, paid subscriptions, and premium content tiers are built into Beehiiv. You can monetize your newsletter from day one without stitching together payment processors.

Clean writing experience. The email editor is fast and produces clean designs. No drag-and-drop complexity — just write, format, send.

Analytics that matter. Open rates, click rates, subscriber growth, revenue per subscriber. The dashboard is focused on what newsletter operators actually care about.

What Beehiiv doesn’t do

Advanced automation. Beehiiv’s automation sequences are basic compared to ConvertKit or Mailchimp. If you need complex branching workflows triggered by user behavior, Beehiiv falls short.

E-commerce integration. Beehiiv isn’t designed for transactional emails, abandoned cart sequences, or deep product integration. It’s for newsletters, not product emails.

Beehiiv pricing

Free for up to 2,500 subscribers. The Scale plan at $39/month unlocks premium features, referral programs, and removes Beehiiv branding.

ConvertKit: Best for Creators Selling Products

ConvertKit (now technically “Kit”) is designed for creators who sell digital products — courses, ebooks, coaching, communities. If you’re building an audience to sell something to, ConvertKit’s model fits perfectly.

What ConvertKit does well

Visual automation builder. ConvertKit’s automation tool is the best in this category. Build sequences that branch based on subscriber behavior — opened email A, clicked link B, purchased product C. It’s powerful without being overwhelming.

Tagging and segmentation. Tag subscribers based on actions, interests, or products purchased. Then send targeted emails to specific segments. This matters when you have multiple products or content tracks.

Landing pages and forms. ConvertKit includes a landing page builder and customizable email capture forms. Not as polished as a dedicated tool, but good enough that many creators skip building a separate landing page.

Commerce built in. Sell digital products directly through ConvertKit. Courses, downloads, paid newsletters, tip jars — no separate payment processor needed for digital goods.

What ConvertKit doesn’t do

Newsletter network effects. ConvertKit doesn’t have Beehiiv’s recommendation network or referral programs. Growth is on you.

Sophisticated email design. ConvertKit defaults to plain-text-style emails (which actually perform well), but if you want highly designed visual emails, the editor is limited.

ConvertKit pricing

Free for up to 10,000 subscribers (with limited features). The Creator plan starts at $29/month and unlocks automations and sequences.

Mailchimp: The Familiar Default

Mailchimp has been around since 2001 and powers millions of email lists. It’s the tool most people think of first, but that doesn’t make it the best choice.

What Mailchimp does well

Template variety. Mailchimp’s drag-and-drop email builder has the most templates and design flexibility. If you want visually rich, branded emails, Mailchimp’s editor delivers.

Integrations everywhere. Every tool on the internet integrates with Mailchimp. WordPress, Shopify, Squarespace, Zapier — Mailchimp is the universal connector.

Mature platform. Twenty-plus years of development means Mailchimp handles edge cases, compliance, and deliverability well. It’s a reliable workhorse.

Why Mailchimp is losing ground

Pricing has gotten aggressive. Mailchimp’s free tier was gutted in recent years. You now pay for features that Beehiiv and ConvertKit offer free. The Standard plan at $20/month has contact limits that competitors don’t.

Complexity creep. Mailchimp has added CRM, website building, social posting, and a dozen other features. The interface is cluttered and the core email experience has suffered.

Intuit acquisition. Since Intuit bought Mailchimp, the platform has leaned further into “all-in-one marketing platform” territory. If you just want email, you’re paying for a lot of features you don’t need.

When to choose Mailchimp

Choose Mailchimp if you’re already using it (migration is painful), you need deep e-commerce email integration with Shopify, or you want the most visually designed emails.

The Honest Recommendation

Starting a newsletter? Beehiiv. The growth tools and newsletter-specific features make it the obvious choice.

Selling digital products? ConvertKit. The automation and commerce features are built for this exact use case.

Running an e-commerce store? Mailchimp, reluctantly. The Shopify integration is the strongest.

Not sure? Start with Beehiiv’s free tier. You can migrate later, and Beehiiv’s growth tools help you build the list faster than either alternative.

Building Your First Email List

Regardless of which platform you choose, the mechanics of list building are the same.

The signup form

Put an email signup form on every page of your site. Not a popup that appears after 3 seconds — a permanent, visible form. The footer is the minimum. A dedicated section on your homepage is better.

Your signup form needs one thing: a compelling reason to subscribe. “Subscribe to our newsletter” is not compelling. “Get weekly teardowns of what’s working in AI-built startups” is compelling. The value proposition matters more than the form design.

The lead magnet

A lead magnet is something you give away in exchange for an email address. Effective lead magnets for founders:

• A downloadable checklist or template
• A free tool comparison guide
• An exclusive case study
• Early access to new features
• A mini email course (5 emails over 5 days)

The lead magnet should be genuinely useful, not a thinly disguised sales pitch. People can smell garbage from a mile away.

The welcome sequence

When someone subscribes, don’t just add them to your list silently. Send a welcome sequence of 3-5 emails over the first week:

1. Immediate: Welcome email with the lead magnet, introduce yourself, set expectations
2. Day 2: Your best piece of content — prove value immediately
3. Day 4: A useful resource or tool recommendation
4. Day 6: Your story — why you’re building what you’re building
5. Day 7: Soft ask — reply with their biggest challenge

This sequence builds the relationship and sets the tone for all future emails.

Writing Emails People Open

Subject lines

The subject line determines whether your email gets opened. Rules that work:

• Keep it under 50 characters
• Be specific, not clever (“3 tools that replaced my marketing team” beats “This week’s roundup”)
• Use numbers when relevant
• Create genuine curiosity without being clickbait
• Test different styles and check what gets higher open rates

Email content

• Write like you’re talking to one person, not an audience
• Keep paragraphs short — 2-3 sentences max
• One main idea per email
• Always include one clear call to action
• Send consistently — weekly is the sweet spot for most founders

The one metric that matters early on

Open rate. If people aren’t opening your emails, nothing else matters. A healthy open rate is 40%+ for a small list. If yours is below 30%, your subject lines need work or your content isn’t matching subscriber expectations.

Email is a long game. Start building your list today, send your first email this week, and stay consistent. Six months from now, you’ll have an asset that no algorithm can take away.
