Email marketing is a way of building relationships and making sales by sending regular, personalized e-mails to people who have given their permission. First you collect a permission-based list, split contacts into segments by interest and behavior, set up automated flows such as welcome and cart reminder e-mails, and measure campaigns by sales rather than opens and clicks.
Why Is Email Marketing Still Powerful?
On social media, an algorithm decides who sees your post; in search results, your ranking can change with every update. An email list, however, is your own asset. Even if platforms change, the list stays with you and your message goes straight to the inbox.
Email marketing is especially strong for repeat sales. Someone who has bought once or asked for information already knows you. A reminder sent to them at the right time costs far less than finding a new customer.
But this power rests on permission and trust. Purchased lists, unsolicited sends and excessive frequency create legal risk and also damage your domain's reputation, sending your e-mails to the spam folder.
Building a Permission-Based Mailing List
The golden rule of building a mailing list is to tell people clearly why they should sign up. “Subscribe to our newsletter” is a weak call; “New-season products and subscriber-only deals twice a month” is a concrete promise.
- Sign-up form on your site: at the bottom of the home page, at the end of blog posts and on the checkout page with a clear consent checkbox.
- A valuable gift: a checklist, a PDF guide, a first-order perk.
- In store and at events: a sign-up page reached by QR code at the physical location.
- Existing customers: add only those who have given explicit permission before.
Make the sign-up page a separate page
If you collect subscribers through ads or social media, send visitors not to the home page but to a page whose only purpose is sign-up. A focused landing page design with the promise, a sample newsletter and a short form noticeably increases the sign-up rate. The brand voice and visuals on this page should match the newsletter; brand management work lays a good foundation for a consistent language.
KVKK and Commercial Message Rules
In Türkiye, commercial electronic messages are subject to e-commerce legislation as well as personal data protection rules. In general terms, you are expected to obtain the recipient's prior consent, offer an easy opt-out (unsubscribe) in every message, and manage permissions through the Message Management System (İYS), the Turkish national consent registry.
On the sign-up form, link to the privacy notice explaining the purpose for which personal data is processed, and keep a record of who gave consent, when and through which form. For more articles on the subject, see the KVKK tag page.
Important: This section is general information. Legislation and practice details may change; before you start sending, check the current legislation with your legal adviser and your accountant.
Segmentation: the Right Message
Sending everyone the same e-mail is the easiest but least effective way. Segmentation means splitting the list into groups by shared characteristics and sending each group a message suited to its needs.
Even three or four segments make a big difference for a small business. What matters is that a segment is based on a behavior or a genuine interest.
| Segment | Example criterion | Suitable message |
|---|---|---|
| New subscribers | Signed up in the last 30 days | Brand introduction, best sellers |
| First-time buyers | A single order | Usage tips, complementary products |
| Loyal customers | Three or more orders | Early access, thank-you note |
| Dormant subscribers | Haven't opened for a long time | Re-engagement or removal from the list |
Automated Email Flows
Automated flows are e-mail sequences that you set up once and that run by themselves every day. Campaign e-mails go to everyone on set days; flows are sent in response to a person's action and therefore usually get more attention.
Welcome series
The first e-mail right after sign-up arrives when interest is at its highest. Deliver the gift you promised, introduce your brand briefly and send your most valuable content a day or two apart.
Cart reminder
A reminder e-mail sent a few hours later to a permission-based customer who added a product to the cart but did not complete the payment is one of the most productive flows in e-commerce. The product photo, the price and a link back to the cart are enough; you do not have to offer a discount every time.
After the sale
Order confirmation, shipping information, a usage tip and, after a suitable interval, a review request. This flow lays the groundwork for repeat sales. Because it works with order data, flows need to be connected directly to your e-commerce infrastructure.
How to Prepare Newsletter Content
An effective email newsletter carries a single main idea. Cramming five different topics into the same e-mail tires the reader and leaves no call to action standing out.
You can use your blog posts as a content source; each newsletter can carry a summary of a post and its link. We described the strategic side of this approach in what content marketing is. When choosing topics, keyword research also helps you find the questions customers actually search for.
- Subject line: short, clear, intriguing and not misleading.
- Preview text: a second sentence that complements the subject line.
- One main call to action: a prominent button, a clear action.
- Mobile-friendly: a single column, large text, touch-friendly buttons.
- Image and text balance: e-mails made up only of images are both unreadable and a spam risk.
Reaching the Inbox: Deliverability
Even the best e-mail is useless if it lands in the spam folder. Deliverability depends on the verification of your sender domain and your sending habits. Major e-mail providers expect SPF, DKIM and DMARC records and easy unsubscribing from bulk senders.
These records are added to your domain's DNS settings. The values vary with the sending service you use; the example below only shows the format.
- Send campaign e-mails from a sending service, not from a personal e-mail account.
- Regularly clean out addresses with no engagement for a long time.
- Do not suddenly increase sending frequency; grow volume gradually on a new domain.

Because of privacy features, open rate is no longer a reliable metric. What you should really look at are clicks, site visits and sales. Add UTM parameters to newsletter links to track the e-mail channel separately in analytics.
After every campaign, ask three questions: How many people clicked, how many bought or filled in a form, and how many unsubscribed? Note the topics and frequencies that drove unsubscribes up; list health is the guarantee of long-term sales.
E-mail gives the best results not alone but together with other channels. When subscribers gathered through ads, campaigns announced on social media and sign-up forms on your site are managed in a single plan, your digital marketing budget is used more efficiently. Connecting sending, CRM and site data is part of integrated solutions.
Frequently Asked Questions
01How often should I send a newsletter?
Send at the frequency you promised and stay consistent. For most small businesses, two to four sends a month is a good start; if unsubscribes rise, reduce the frequency.
02Can I use a purchased email list?
It is not recommended. These people have not given permission specifically to you; it carries legal risk, and complaints damage your domain's reputation, making delivery of all your sends harder.
03Do I need to know how to code to design a newsletter?
No. Most sending services offer a drag-and-drop editor. Even so, having a master template prepared that matches your brand colors and fonts and has been tested on mobile saves time with every send.
04Is there a relationship between backlinks and email?
There is an indirect relationship. When you announce valuable content in your newsletter, the chance of it being shared and linked to from other sites increases; we covered this in our article on what a backlink is.
Email marketing, with a permission-based list, the right segments and well-built automated flows, is the most ownable channel for bringing in steady sales.
