Email newsletters for small businesses: building a list and writing emails people open

An email newsletter is a regular message you send to people who have asked to hear from you: customers, past enquirers, dealers or website subscribers. Its main value is that the list belongs to you. Social media reach rises and falls with platform changes, but an email list stays with your business. To make it work you need three things: a list built with permission, emails useful enough to open, and a sending set-up that keeps you out of spam folders.

Is email worth it in Bangladesh?

Many Bangladeshi customers live in Messenger and WhatsApp, and email is not the first place they look. For many consumer shops, that is simply true. But email works well where people use it for work or for important matters: business buyers, foreign customers of exporters, professionals, students applying for courses, software users, and repeat buyers of higher-value items. If your customers give you their email address when they order or enquire, email is worth trying.

Building a list the right way

• Ask at natural moments: at checkout, on an enquiry form, at a trade fair stand, or with a sign-up sheet at your counter.
• Give a reason to join: "See new arrivals first", "Monthly tips for poultry farmers" or "Price updates for dealers".
• Use an unticked box, so people choose to join, rather than adding everyone who orders.
• Never buy or scrape lists. People who did not ask for your emails mark them as spam, and that hurts delivery to everyone else on your list.
• Keep the list clean: remove addresses that bounce, and people who have not opened anything for a long time.

A short welcome email, sent automatically when someone joins, is worth setting up early. Thank them, tell them what you will send and how often, and give them something useful straight away.

What to send

People open emails that help them, not only emails that sell. A good mix might include:

• New products or services, with clear prices where you can share them.
• Practical tips related to what you sell, such as caring for a fabric or maintaining a machine.
• Answers to questions customers often ask.
• Seasonal offers, sent with enough notice to act on them.
• News from the business: a new branch, a new process, a new team member.

Keep one main message per email, with one clear link or button. A furniture maker in Natore, for example, might send a monthly email with one featured piece, one care tip and a reminder of the areas they deliver to.

Writing emails people open

The subject line decides whether the email is opened. Make it specific and honest:

• Weak: "Newsletter No. 12" or "HUGE OFFER!!!"
• Better: "New winter shawls, now in five colours" or "How to keep your water tank clean"

Other habits that help:

• Use a sender name people recognise, such as your business name, or the owner's first name with the business name.
• Write the short preview text that appears after the subject line.
• Keep paragraphs short; most people read on their phones.
• Write in the language your readers use. Bangla emails display well on most modern phones, but send a test to yourself first.
• Use images sparingly, and make sure the email still makes sense if images do not load.

Staying out of the spam folder

Send from an address on your own domain rather than a free email address, and set up the authentication records (SPF, DKIM and DMARC) that your email service explains. Large mailbox providers have become stricter with bulk senders, so follow your email tool's current guidance. Put a clear unsubscribe link in every email. People expect it, and it is far better for someone to leave than to mark you as spam.

How often to send, and what to measure

Choose a rhythm you can keep. Monthly is a sensible start for most small businesses, and consistency matters more than frequency.

Judge results by clicks, replies and sales from email rather than by opens alone. Some email apps load images automatically, which makes open counts less reliable than they once were. Tag the links in your emails with UTM parameters so your analytics can show which newsletter brought visitors and orders.

Your first month

1. Choose an email tool that handles sign-ups, unsubscribes and authentication for you.
2. Set up email on your own domain if you have not already.
3. Add a sign-up box to your website and checkout, with a clear reason to join.
4. Write a welcome email and your first newsletter.
5. If you are starting from an older list, verify the addresses before the first big send.
