You send emails, but few people open them and even fewer click? It’s not that email “doesn’t work.” Usually one of three things is missing: the right people on your list, content that interests them, or a system for evaluating your campaigns. This guide walks you through the whole process, from preparation through creation and timing to tracking.
What you need before your first campaign
A tool
Choose an email sending tool that handles templates, segmentation, and basic automation, and connects to your website or online store. For small businesses, a standard tool such as Ecomail, Mailchimp, or SmartEmailing is usually enough. When choosing, check whether the interface is in a language you understand, what kind of support they offer, and how the price changes with the number of contacts.
Consent and GDPR
Send marketing emails only to people for whom you have a valid legal basis, most often active consent. No pre-checked boxes and no purchased lists. Every email must include an easy way to unsubscribe. If anything is unclear, it’s worth consulting a lawyer, because breaking data protection rules can get expensive.
A quality list
Ten people who actually want your emails are worth more than a thousand random addresses. Collect contacts on your website, in your store, at checkout, or at events, and always say what they’ll be receiving. We explain why your own contact list is so valuable in Why one email address is worth more than 100 Instagram followers.
Key elements of an effective campaign
Segmentation
Segmentation means dividing your contacts into groups with shared needs. The same email for everyone is the fastest route to low open rates. Proven segments:
- new subscribers: a welcome and an introduction,
- customers after their first purchase: product tips and a next offer,
- loyal customers: early access to new products and a thank-you,
- inactive contacts: re-engagement with a clear reason to come back.
You’ll find how to build segments step by step in Segmenting your email list.
Personalization
Using someone’s first name is just the start. Real personalization means the content matches what the person bought, viewed, or is interested in. A customer who bought running shoes will appreciate training tips more than an offer for winter boots. More in Personalization in email marketing.
Subject line
The subject line decides whether the email gets opened at all. Put the value up front, be specific, and promise only what the email actually contains. “Fall coat sale ends Sunday” says more than “A great opportunity for you.” A shorter subject line shows in full on mobile too. Add a preheader, the text that appears right after the subject line in the inbox.
Content and call to action
One email, one main goal. Write short paragraphs that are easy to scan. The main button must stand out and be specific: “See the new coats” instead of “Click here.” The link should lead to a page with the specific offer, not your homepage.
Mobile version
Many people read email on their phones. Use a single-column layout, a large enough font, and buttons that are easy to tap. Always send the email to your own phone before sending it out.
Timing and frequency
There’s no universally best time to send. B2B emails are often read during working hours, consumer emails in the evening or on weekends too. The safest approach is to test and watch when your own people open their emails.
When it comes to frequency, regular and meaningful beats frequent and empty. Here’s how to find the right rhythm:
- Start with, for example, one email a week or two a month.
- Track opens, click-throughs, and unsubscribes for a few weeks.
- Try a higher frequency for part of your list.
- Compare both groups, looking not only at opens but also at revenue and unsubscribes.
- Let subscribers choose how often they want to receive emails.
Avoid sending without context during holidays, and don’t forget time zones if you also send emails abroad.
Testing and automation
An A/B test means part of your list gets version A, part gets version B, and you compare the results. Test only one thing at a time: the subject line, the call to action, an image, or the length of the copy. Then send the winning version to the rest of the list.
Alongside one-off campaigns, it’s worth setting up automated flows that send themselves when a specific event happens:
- a welcome series for new subscribers,
- an abandoned cart reminder,
- a thank-you and tips after a purchase,
- a product review request,
- re-engaging people who haven’t bought in a while.
We cover how to set them up and what to avoid in Email marketing automation.
Example: one campaign from start to finish
Picture a small coffee roastery with an online store that wants to sell a new blend in the fall. Its campaign could look like this:
- Goal: sell the new blend to customers who have already bought from the roastery.
- Segment: customers with at least one purchase in the past year. New subscribers get the welcome series instead.
- Subject line: “New fall blend: chocolate, nuts, and a hint of spice.” Preheader: “Three days early for our regulars.”
- Content: a short story about where the coffee comes from, a photo, the flavor profile, and a brewing tip. One button: “Try the new blend.”
- Test: half of the segment gets a different subject line, and the winning version goes to the rest a day later.
- Tracking: a link with UTM parameters, plus order tracking in the online store and in Google Analytics 4.
You can prepare the whole campaign in one afternoon. You then use the results in the next one, so every campaign learns from the one before.
How to measure success
- Open rate: gives a rough idea of the strength of your subject line and trust in the sender. Some email apps distort it, though, so take it with a grain of salt.
- Click-through rate: what share of recipients clicked a link. It tells you whether the content caught people’s interest.
- Conversions and revenue: the most important numbers. Connect your tool with Google Analytics 4 or your online store.
- Unsubscribes and spam reports: a signal that you’re sending too often or to the wrong people.
Compare results mainly with your own previous campaigns. Averages from other countries and industries tell you little about your list. Once a month, look at the trend and write down what you changed and with what result.
The most common mistakes
- Buying lists instead of building your own.
- The same email for everyone, with no segmentation.
- Misleading subject lines that raise opens but lower trust.
- No testing, and decisions based on gut feeling.
- An email that’s hard to read on mobile.
- A link that leads to a generic page instead of a specific offer.
Pre-send checklist
- The subject line and preheader are specific and honest.
- The email goes to the right segment.
- All links work and lead to the right page.
- The email displays well on mobile.
- It includes an unsubscribe link and sender details.
- Links have UTM parameters, so you can see the results in Google Analytics 4.
Frequently asked questions
How do I increase my email open rate?
Send emails to people who want them, write specific subject lines, and test them. Regularly cleaning inactive addresses from your list and sending from an address people recognize also helps.
Which tool is best for a small business?
One that connects easily to your website or online store, has a clear interface, and offers support you can communicate with. Before deciding, try the free trial of two or three tools.
How often should I send emails?
As often as you have something meaningful to say. For many small businesses, one email a week or two a month is a good start. Then adjust the frequency based on unsubscribes and results.
What should I do with inactive contacts?
Send them a re-engagement email with a clear reason to come back. If they still don’t respond, remove them from your list. A smaller but active list gets better deliverability and better results.
