How I Do Email Marketing for $0 a Month (and Still Get Opens)

I remember staring at my Mailchimp bill three years ago—$59 a month for a list of 1,200 subscribers I'd barely touched. That hurt. So I challenged myself: could I run my weekly newsletter for exactly $0? No tricks, no hidden fees. I canceled my paid plan, migrated everything to free tools, and haven't spent a dime on email marketing since. My open rates actually went up. Here's exactly how I did it—and how you can, too.

Why I Ditched Paid Email Tools (and You Can Too)

When I started my small online store selling custom notebooks, I grabbed Mailchimp because everyone said it was the best. It was fine—until my list grew past 500 subscribers. Then the pricing tiers kicked in. I was paying for features I never used: fancy templates, advanced segmentation, A/B testing. Meanwhile, my open rates hovered around 18%. Not great for $59 a month.

One afternoon, while scrolling through Reddit, I stumbled onto a thread about MailerLite's forever-free plan. Someone had 950 subscribers and sent 10,000 emails a month—all free. No credit card required. I switched within a week. The migration was clunky (exporting CSV files manually took an hour), but after that first free month, I felt like I'd escaped a trap. I haven't looked back.

The truth is, most small businesses outgrow paid tools long before they need them. If you have fewer than 1,000 subscribers, you're overpaying. Even at 1,500, you can stretch free limits with smart strategies. The catch? You lose some bells and whistles—but you gain peace of mind and a healthier budget.

My Free Email Toolkit: What I Actually Use

I rely on three core tools that cost exactly zero dollars. Here's the honest breakdown:

• MailerLite (Free Plan): This is my main driver. Up to 1,000 subscribers, 10,000 sends per month. It handles basic automation, landing pages, and pop-ups. The email editor is simple—drag and drop, no coding. Downsides: The free plan puts a small "Powered by MailerLite" in the footer (I don't mind), and you can't remove it without paying. Also, their customer support on free tiers is email-only, not live chat.
• Brevo (formerly Sendinblue) (Free Plan): I use this as a backup for transactional emails—like order confirmations or password resets. Brevo's free tier offers 300 emails per day, unlimited contacts. It's good for low-volume automation. The drag-and-drop editor is clunkier than MailerLite's, but it works.
• Amazon SES + Sendy (Self-Hosted, Almost Free): When I tested a second newsletter for a side project with 2,500 subscribers, I used Amazon Simple Email Service (SES) combined with Sendy—a PHP script that costs a one-time $59 fee (not monthly). The per-email cost is about $0.0001. Yes, that's a tenth of a cent per email. For my 2,500 subscribers, I paid roughly $0.15 per month. The trade-off? It requires technical setup—you need a basic web server and some comfort with DNS records. If you're not tech-savvy, stick with MailerLite until you hit 1,000.

My honest verdict: MailerLite's free plan is the best balance of ease and power for most small businesses. If you outgrow it, self-hosting with SES is the cheapest path—but it's not for everyone.

How I Build a List Without Spending a Dime

Growing my email list cost me exactly $0. Here's what worked:

• Website pop-ups (free via MailerLite): I set up a simple exit-intent pop-up offering a free "Notebook Lover's Checklist"—a PDF with tips for organizing your writing life. It converts at about 3.5% of visitors. No fancy tools needed.
• Social media cross-promotion: I added a "Get my free newsletter" link in my Instagram bio and Twitter profile. Every week, I'd post a screenshot of my latest email's best tip with a caption like "Want more? Join the list—free." That drove about 15 new sign-ups per month.
• Referral incentives (no money): I asked existing subscribers to share the newsletter with a friend. No prize—just a genuine ask. About 5% of my subscribers forwarded it to someone. That organic growth added 5–10 people monthly.
• Guest posts (free): I wrote two guest articles for small business blogs, with a bio link to my newsletter sign-up. Each post brought about 30–50 subscribers.

One surprising lesson: A simple, specific lead magnet (like a checklist) outperformed a generic "subscribe for updates" by 4x. People want immediate value, not vague promises.

Crafting Emails That Get Opened (Even on Free Plans)

Free plans usually don't include A/B testing or advanced analytics. So I rely on three manual tactics that boosted my open rate from 18% to 32%:

1. Subject lines with a number or question: "5 Notebooks That Changed My Writing" beats "My Favorite Notebooks" every time. I test two subject lines manually—send half the list one, half the other, then use the winner for the rest. It's not automatic, but it works.
2. Personalized preview text: I add a first-name merge tag in the preview text. MailerLite's free plan supports this. Example: "Hi {{first_name}}, here's a tip you'll love." It feels human.
3. Send at the right time: I studied my own data. For my audience (writers and small biz owners), Tuesdays at 10 AM ET got the highest opens. I stuck to that schedule religiously. No fancy tool—just a calendar reminder.

One counter-intuitive insight: Shorter subject lines (under 40 characters) actually performed worse for me. Longer, curiosity-driven lines (50–60 characters) got more clicks. Tests on free plans taught me that my audience prefers context over brevity.

Automation Without the Price Tag

Automation is where free tools often fall short. But I found workarounds:

• Welcome sequence: MailerLite's free plan allows one automated email after sign-up. I set a simple two-step: 1) Immediate welcome with the lead magnet link, 2) A manual email I send 48 hours later (I schedule it in advance). It's not true drip automation, but it's close enough.
• Abandoned cart reminders: I use Brevo's free plan for these. When someone adds a notebook to cart and doesn't buy, I send a manual reminder 24 hours later. Brevo's free tier lets me create a simple automation for this—one email, no cost.
• Manual workflows: For seasonal promotions, I export my list to a CSV, filter by past purchase behavior in Excel, and create a segment in MailerLite. It takes 15 minutes but costs nothing. Not elegant, but effective.

Real example: Last December, I set up a "12 Days of Writing Tips" campaign. I wrote each email manually, scheduled them in MailerLite's free plan (which allows up to 10 scheduled sends per day). It drove a 40% open rate and 12% click-through—better than any paid automation I'd used before.

Final Takeaway: The $0 Email Strategy Is Real

I've been running my newsletter on free tools for two years now. My list hovers around 900 subscribers, my open rate stays above 30%, and I've never spent a penny. The key is to start small, use free tools that fit your list size, and focus on craft—not features. When you hit the 1,000-subscriber ceiling, you have options: upgrade to a low-cost tier ($10–$15/month) or go self-hosted with SES. But for most of us, $0 works beautifully.

If you're paying for email marketing right now, challenge yourself. Switch to a free plan for one month. You might be surprised what you gain.
