How to Set Up Email Marketing for Your Small Business

Email marketing remains one of the highest-return channels available to small businesses. Unlike social media, where algorithms decide who sees your content, email lands directly in your subscriber’s inbox. You own the relationship, and every message you send reaches people who have already told you they want to hear from you.

Setting up email marketing does not need to be complicated or expensive. Most platforms offer a free tier that is more than sufficient for businesses just getting started. The key is understanding the steps involved, choosing the right tool for your needs, and building good habits from day one rather than trying to fix a tangled list later.

Choosing an Email Marketing Platform

The most widely used platforms for small businesses are Mailchimp, Brevo (formerly Sendinblue), Kit (formerly ConvertKit), and Klaviyo. Each has strengths: Mailchimp is beginner-friendly and well-documented; Brevo offers generous free sending limits and SMS in the same tool; Kit is popular with content creators and coaches; Klaviyo is the standard for e-commerce stores. If you are just starting out, Mailchimp or Brevo are sensible first choices. You can always migrate later, though it is easier to get it right first time.

Look at the free plan limits before you commit. Most platforms allow you to store a certain number of contacts and send a certain number of emails per month without paying. As your list grows, you will move onto a paid tier, so check the pricing at the next level up before signing up so there are no surprises later.

Building Your Subscriber List

Your list is the foundation of everything. Start with a simple sign-up form on your website — your homepage, your footer, and any blog or resources page are the obvious places. Keep the form short: name and email address is usually enough. Every additional field you ask for reduces the number of people who complete it.

Beyond your website, add a link to your email sign-up in your email signature, your social media profiles, and any printed materials you produce. At events or in person, ask people directly whether they would like to receive your newsletter. Every contact you add legitimately is worth more than a purchased list of cold addresses, which will damage your deliverability and likely violate GDPR.

Sending Your First Campaign

Before you send to your full list, test your email thoroughly. Send it to yourself and check it on both desktop and mobile, because a layout that looks fine in your browser can break on a phone. Check every link, make sure your unsubscribe option works, and confirm your sender name and email address look professional.

For your first campaign, focus on a single message rather than trying to pack in everything at once. A welcome email introducing yourself and explaining what subscribers can expect is a perfectly good start. Consistency matters more than frequency — a monthly newsletter you actually send is worth far more than a weekly one you abandon after three issues. Set a realistic schedule and stick to it.
