Email marketing for small businesses in Serbia — how to start without a budget or expensive tools

The average email marketing ROI is €36 for every €1 invested — more than any other digital channel. Unlike an Instagram or Facebook post seen by 3–5% of followers, an email reaches 100% of subscribers' inboxes. Your email contact list belongs to you — no algorithm can take it away. For small businesses in Serbia, an email list is the most valuable digital asset you can build.

How to build a list without buying contacts (that is spam and punishable under GDPR): (1) A lead magnet on your site — a free guide, checklist, or discount in exchange for an email, (2) A newsletter form on every page with a clear value message, (3) Existing clients — send them an email and ask if they want the newsletter, (4) After every purchase or service — an opt-in with a clear question. 100 relevant subscribers are worth more than 10,000 random ones.

Tools: Brevo (formerly Sendinblue) is free up to 300 emails per day and handles Serbian Latin script without issues — we recommend it to start. Mailchimp is free up to 500 contacts but limits automation on the free plan. MailerLite is an excellent price-to-feature balance for growing businesses. All are GDPR-compliant and have good documentation.

Five emails every business should send: (1) A welcome email immediately on sign-up — an introduction, what they can expect, (2) A monthly newsletter with useful content (not only promotions), (3) A post-purchase or post-service email asking for a review, (4) A reactivation email for clients who have not purchased in 6+ months, (5) Seasonal emails for holidays or current events relevant to your industry.

Automation: even free plans support a welcome sequence (a series of 2–3 emails during the first week) and abandoned cart emails for e-commerce. Once set up, this runs without your involvement. Feather Studio integrates Brevo and Mailchimp directly into Next.js and WordPress sites — for automatic contact sync from forms and purchases, get in touch.
