I have an email list. Not a huge one - just over 2,000 people. But my open rate sits steadily at 38-42%. The industry average is 21%.
I don't have a secret formula. I don't have a magic tool. I have a few rules I've stuck to for 3 years. And they work in the Polish market reality, not the American one where every guru sells an email marketing course for $997.
Start with a promise, not a form
The biggest mistake? "Subscribe to our newsletter." That's like saying "give me your phone number, I'll call you sometime."
People don't want a "newsletter." They want a solution to a problem. Value. A specific benefit.
My signup form doesn't say "newsletter." It says: "Every week you get one thing you can implement in your marketing. No fluff."
Good promises from lists I run for clients:
- "Every Friday - 3 post ideas, ready to use" (beauty salon, 35% open rate)
- "Once a week - a specific SEO tip you can implement in 15 minutes" (agency, 41% open rate)
- "Food industry news + 1 daily special recipe" (food wholesale, 44% open rate)
See the pattern? Specificity + frequency + benefit. No "stay up to date with our news."
Subject line - you have 3 seconds
Your email competes for attention with 50 others in the inbox. The subject line is the only thing that decides whether someone clicks or scrolls past.
My subject line rules:
- Short. 5-8 words. Longer ones get cut off on phones
- Specific. "3 mistakes in your ads" > "Marketing tips"
- Personal. Write like you're texting a friend, not a database
- No clickbait. The content must deliver what the subject promises
Subject lines with my highest open rates:
- "I lost a client. Here's why." - 52% open rate
- "This post cost me $3 and brought 4 leads" - 48% open rate
- "Don't do this on Instagram (seriously)" - 45% open rate
What doesn't work? "Newsletter #47," "Weekly roundup," "What's new in our offer." Boring. Predictable. Skip.
Write like a human, not a company
A newsletter is not a press release. It's a letter. From one person to another.
I write my newsletter as if I'm writing to a friend who runs a business. I say "I." I tell stories from the week. I admit mistakes. I crack jokes.
A few rules:
- Write from "I," not "we" or "the company." People read people, not brands
- One topic per email. Not three. Not five. One
- Short paragraphs. 2-3 sentences. A wall of text guarantees nobody finishes reading
- One CTA. Don't include 5 links. Include one and tell the reader what to do with it
My newsletter averages 400-500 words. Takes 2-3 minutes to read. And that's intentional. Because I know my readers are business owners with 47 things to handle who read emails between meetings.
I respect their time. And they appreciate it - because they don't unsubscribe.
Frequency and consistency
Once a week. Always the same day. For me it's Tuesday, 8:00 AM.
Why Tuesday? Because Monday is chaos. Wednesday is mid-week. Friday is "almost weekend." Tuesday morning people have dealt with Monday's fires and have a moment to read something valuable.
But honestly? The day doesn't matter as much as consistency. Send on Friday if you want. But ALWAYS send on Friday.
I once skipped 3 weeks in a row. Open rate dropped from 40% to 31%. Took 2 months to rebuild.
Because people get used to it. Tuesday morning - email from Kaminski. If it's not there, you fall out of rhythm. Then out of memory.
What if you have nothing to write about? You always do. This week you talked to a client? Saw an ad that annoyed you? Made a mistake? That's newsletter material.
Building your list - without spam or desperation
My list grows by 80-120 people per month. Without paid ads for signups. Where do they come from?
- Lead magnet on the blog - ebook, checklist, template (60% of signups). How to build that content base I described in my article on content marketing strategy
- Form in the website footer - simple, with a promise (15% of signups)
- Social media - newsletter excerpt + "the rest in your inbox" (20% of signups)
- Referrals - "forward to a friend" in the newsletter footer (5% of signups)
What I do NOT do:
- I don't buy email lists. Ever. That's a direct path to spam folders and domain destruction
- I don't add people without their consent. Not even business cards from networking events
- I don't promise things I won't deliver
A small, engaged list beats a large, dead one. 2,000 people with a 40% open rate means 800 people reading your emails every week. 10,000 people with an 8% open rate is the same number - but with 5x the tool cost and 5x worse deliverability.
You don't need a bigger list. You need a better relationship with the people already on it.
Tools and costs
Finally - the practical stuff. What I use and what it costs.
Up to 1,000 subscribers you have plenty of free options. MailerLite - free up to 1,000 contacts with decent automation. I use it for smaller clients.
Above 1,000 - MailerLite Growing Business at $10/month or ConvertKit at $29/month. Both get the job done.
You don't need Mailchimp at $100+. You don't need HubSpot. Not at this stage.
Total cost of running my newsletter: $10/month for the tool + 2 hours per week writing. It generates an average of 3-5 quote requests per month. Each worth $500-1,500.
Hard to find a better ROI in marketing. But you have to write. Consistently. Even when you feel like nobody's reading. Because they are. And one day they'll write "I've been reading your newsletter for six months and I'd like to talk about working together."
I know. Because I get those emails every month.
