Email Marketing Basics
Learn how to write newsletters, grow your subscriber list, craft great subject lines, and stay on the right side of UK email laws — including age restrictions for email platforms.
Why Email Marketing Still Matters
You might think email is something your parents use and that everything happens on social media now. But here is a surprising fact: email marketing generates an average of £36 for every £1 spent. That makes it one of the most effective marketing channels for any business — including yours.
Here is why email beats social media for selling:
- You own your list. If Instagram changes its algorithm tomorrow, your posts might reach 5% of your followers. But your email list is yours — no algorithm decides who sees your message.
- Higher conversion rates. About 3-5% of people who receive a marketing email will take action (click a link, buy something). On social media, it is closer to 0.5-1%.
- Direct and personal. An email lands in someone's inbox with their name on it. It feels like a conversation, not a broadcast.
- Perfect for updates. Backers and customers want to know what is happening with your project. Email is the best way to keep them informed.
Age Restrictions: What You Need to Know
Platform Age Requirements
Most email marketing platforms require users to be at least 16 or 18 years old to create an account. Here are the main ones:
| Platform | Minimum Age | Free Plan |
|---|---|---|
| Mailchimp | 18 | Yes (up to 500 contacts) |
| Buttondown | 16 | Yes (up to 100 subscribers) |
| MailerLite | 16 | Yes (up to 1,000 subscribers) |
| Brevo (formerly Sendinblue) | 18 | Yes (300 emails/day) |
What This Means for You
If you are under the minimum age, you have two options:
- Ask a parent or guardian to create the account in their name, with you managing the content. This is perfectly fine and is how many young entrepreneurs handle it.
- Use a platform with a lower age requirement like Buttondown or MailerLite (16+).
Your teacher or mentor can also help you set this up as part of your Futurepreneurs project.
UK Email Laws: PECR and GDPR
Before you send a single email, you need to understand the rules. In the UK, sending marketing emails is governed by two laws:
PECR (Privacy and Electronic Communications Regulations)
The key rule: you cannot send marketing emails to someone unless they have given you clear permission (consent) to do so.
This means:
- You must have an opt-in process (people actively choose to receive your emails)
- You cannot buy email lists or add people without their consent
- You cannot scrape emails from social media and add them to your list
- Pre-ticked boxes do not count as consent
GDPR (General Data Protection Regulation)
GDPR adds further requirements:
- Tell people what you will use their email for when they sign up
- Let people unsubscribe easily (every email must have an "unsubscribe" link)
- Keep subscriber data secure
- Do not share email addresses with anyone else without consent
- If someone asks you to delete their data, you must do it
What This Looks Like in Practice
When someone signs up for your email list, use a clear statement like:
"By entering your email, you agree to receive updates and marketing emails from [Your Business Name]. You can unsubscribe at any time."
Every email you send must include:
- Your business name
- A working unsubscribe link
- Your contact information (a business email address is fine — you do not need a physical address as a sole trader under 18)
Breaking these rules can result in fines, so take them seriously. The good news is that most email platforms handle the technical side (unsubscribe links, data storage) automatically.
Growing Your Subscriber List
Where to Collect Emails
On your Futurepreneurs campaign page:
Your backers automatically have a connection with you through the platform. Encourage them to sign up for your separate email list for exclusive updates and offers.
On social media:
Add a link to your email sign-up in your Instagram bio, TikTok bio, and any other social profiles. Use posts and Stories to promote it: "Want exclusive behind-the-scenes updates? Join our email list — link in bio!"
At events and fairs:
Use a tablet or phone with a Google Form for quick sign-ups. Or use a printed sign-up sheet (but transfer those emails to your platform promptly).
Through your network:
Ask friends, family, and teachers if they would like to receive updates. Remember: you need their explicit consent, so always ask — never just add them.
Lead Magnets: Give People a Reason to Sign Up
A "lead magnet" is something free you offer in exchange for an email address. For a teen business, this could be:
- An early-bird discount: "Sign up for 10% off your first order"
- Exclusive content: "Get a free recipe card when you join our mailing list"
- Early access: "Be the first to know about new products"
- A behind-the-scenes look: "Get monthly behind-the-scenes updates from our workshop"
How Many Subscribers Do You Need?
Quality matters more than quantity. A list of 50 engaged subscribers who open every email is worth more than 500 who never read them. Start small and grow steadily. For a teen business, here is a realistic timeline:
- Month 1: 20-50 subscribers (friends, family, early supporters)
- Month 3: 50-150 subscribers (backers, social media converts)
- Month 6: 150-500 subscribers (growing through word of mouth and content)
Writing Great Emails
The Anatomy of a Marketing Email
Every good marketing email has these parts:
- Subject line — What makes them open it
- Preview text — The snippet visible in the inbox (first 40-90 characters)
- Greeting — Personal and friendly
- Body content — Your main message (keep it focused on ONE topic)
- Call to action (CTA) — What you want them to do next
- Sign-off — Friendly and personal
- Footer — Unsubscribe link, your business name
Subject Line Mastery
Your subject line determines whether someone opens your email or ignores it. Here are proven formulas:
Curiosity:
- "You will not believe what happened this week..."
- "We have a secret to share"
Benefit-driven:
- "Get 15% off our new collection"
- "Your exclusive first look at our new flavours"
Urgency (use sparingly):
- "Last chance: early-bird pricing ends tonight"
- "Only 10 gift boxes left"
Personal:
- "A quick update from our kitchen"
- "What I learned from my first 50 orders"
News:
- "We just hit a major milestone!"
- "Introducing our brand new product range"
Subject Line Tips
- Keep it under 50 characters (many people read email on their phones)
- Do not use ALL CAPS — it looks like spam
- Avoid spam trigger words like "FREE!!!," "Buy now!!!," "Act immediately"
- Use numbers when relevant ("5 new flavours," "Our first 100 orders")
- Test two subject lines — most email platforms let you A/B test to see which performs better
Writing the Body
Keep it short. Aim for 150-300 words. People scan emails — they do not read every word.
Use short paragraphs. Two to three sentences maximum per paragraph. Big blocks of text are intimidating on a phone screen.
Write like you talk. Pretend you are writing to a friend. "Hey! Quick update — we have just finished making the first batch of our new lavender candles and they smell incredible."
Focus on one thing. Each email should have one main topic and one main action you want the reader to take. Do not try to cram three different announcements into one email.
Include images. A photo of your product, your workspace, or you and your team makes the email more engaging. But do not overload it — one or two images is enough.
The Call to Action (CTA)
Every email should have a clear CTA — the one thing you want the reader to do:
- "Shop the new collection" (with a link)
- "Back our campaign" (with a link)
- "Reply and tell us your favourite flavour"
- "Share this with a friend"
Make your CTA button or link stand out. Use a button if your email platform supports it.
Types of Emails to Send
1. Welcome Email
Sent automatically when someone subscribes. Thank them, introduce your business, and tell them what to expect.
2. Campaign Updates
If you are running a Futurepreneurs campaign, send regular updates: "We have hit 50% of our goal!" "Check out our new stretch goal." "Only 10 days left!"
3. Product Announcements
New product? New flavour? New design? Tell your list before you tell anyone else. This makes subscribers feel special.
4. Behind-the-Scenes
Show your process: making products, packing orders, visiting suppliers. People love seeing the human side of a business.
5. Customer Stories
Share positive feedback from backers or customers (with their permission). Social proof is powerful.
6. Seasonal or Themed Emails
Tie your emails to events: "Our Valentine's Day gift guide," "Back-to-school special," "Christmas order deadline."
Measuring Your Results
Key Metrics
Open rate: The percentage of subscribers who opened your email.
- Average for small businesses: 20-25%
- Above 30%: Excellent
- Below 15%: Your subject lines need work
Click-through rate (CTR): The percentage of openers who clicked a link in your email.
- Average: 2-5%
- Above 5%: Excellent
- Below 1%: Your content or CTA needs improvement
Unsubscribe rate: The percentage who unsubscribe after each email.
- Below 0.5%: Normal
- Above 2%: You might be emailing too often or your content is not relevant
How to Improve Your Numbers
- Low open rate? Test different subject lines. Send at different times (Tuesday and Thursday mornings tend to work well).
- Low click rate? Make your CTA clearer and more compelling. Reduce the number of links — one main CTA per email.
- High unsubscribe rate? Email less frequently or make your content more valuable. Ask subscribers what they want to hear about.
How Often Should You Email?
For a teen business, the sweet spot is usually:
- During a campaign: Once a week (plus launch day and final-day emails)
- Between campaigns: Once or twice a month
- Never: More than twice a week (unless you have a very good reason)
Consistency matters more than frequency. If you commit to sending one email every two weeks, stick to that schedule.
Setting Up Your First Email Campaign
Step-by-Step with Buttondown (Teen-Friendly)
- Create an account at buttondown.email (16+ or with a parent)
- Set up your newsletter name (use your business name)
- Customise your sign-up page (add a description and your branding)
- Import existing subscribers (if you have emails from a sign-up form, with their consent)
- Write your first email (a welcome message introducing your business)
- Add your unsubscribe link (Buttondown does this automatically)
- Preview and test (send a test email to yourself first)
- Hit send!
Step-by-Step with Mailchimp (via Parent Account)
- Your parent creates an account at mailchimp.com
- Create an "audience" (your subscriber list)
- Design your sign-up form (Mailchimp has a drag-and-drop builder)
- Create your first campaign (choose "Regular Email")
- Use a template (pick a simple, clean design)
- Write your content and add images
- Preview and test
- Schedule or send
Both platforms have free tiers that are more than enough for a teen business starting out.
Email Marketing Do's and Don'ts
Do
- Get explicit consent before adding anyone to your list
- Include an unsubscribe link in every email
- Write subject lines that are honest (no clickbait)
- Test your emails on mobile before sending
- Be consistent with your sending schedule
- Add a personal touch — your name, your story
Don't
- Buy email lists (it is illegal under PECR and the emails will not convert anyway)
- Send emails every day (you will lose subscribers fast)
- Use misleading subject lines
- Ignore unsubscribe requests
- Share your subscriber list with anyone else
- Send without proofreading (typos look unprofessional)
