Email marketing remains one of the most cost-effective channels for a Belgian small business: unlike social media, your newsletter lands directly in the inbox of a customer who already knows you. In this guide, you will find out how to get started, what GDPR says and what email marketing really costs for a small business in Belgium.

At a glance

• Email marketing costs less than you think: from €35/month excl. VAT for 5 000 emails, with no per-send commission.
• Newsletters build loyalty, one-off campaigns (promotions, follow-ups) convert: the two complement each other.
• GDPR requires consent and a visible unsubscribe link in every email.
• A tool connected to your CRM segments contacts automatically, without manual exports and imports.
• Three to four sends per month are enough to stay on people's minds without tiring your contacts.

Why use email marketing as a Belgian small business?

A Brussels retailer or Liège tradesperson sending a monthly newsletter directly reaches customers who have already bought or requested a quote. It is a channel you own: no algorithm decides who sees your message, no advertising auction. The cost of acquiring a customer by email generally remains far below that of a Google or Meta ad, provided your contact list is clean and your content relevant.

Newsletter or one-off campaign: what is the difference?

A newsletter is regular (monthly or twice monthly): news, new products, advice. It maintains the relationship. A one-off campaign serves a specific goal: an end-of-season promotion, quote follow-up or event invitation. Both are sent from the same tool, but measured differently: open rate for newsletters, click and conversion rates for campaigns.

Which tools are available for email marketing in Belgium?

There are two types of tools:

Eazyclick's Email marketing module belongs to the second group: your contacts, purchases and quote requests are already in your CRM, so segmentation needs no export.

GDPR: what to follow before sending

Three non-negotiable rules in Belgium and throughout the European Union:

• Consent: contacts must have agreed to receive your emails (an unticked opt-in box, or an existing customer for communications related to their purchase).
• Clear identification: your business name and a valid contact address must appear in the email.
• Unsubscribe link: visible, working and removing the contact from the list immediately.

A module connected to your CRM applies these rules automatically to every send: unsubscribing updates the customer record, with no manual action.

How much does email marketing cost for a small business?

Beyond 5 000 emails per month, your project manager adjusts the volume with you: for a small business with fewer than 2 000 contacts, this allowance remains more than enough.

Launch your first campaign in 5 steps

1. Clean your list: remove invalid addresses or those with no opens in a year.

2. Segment: active customers, prospects and former customers should not receive the same message.

3. Write a short subject line: 40 to 50 characters, stating a tangible benefit.

4. Test the send on a small part of your list before the full send, if the volume allows.

5. Measure: open rate, click rate, unsubscribes. Adjust frequency if unsubscribes increase.

The GlowUp package includes a complete CRM that already prepares this segmentation; add the Email marketing module individually or as part of the Booster package.

Frequently asked questions

How many emails can I send per month?

The Email marketing module includes 5 000 emails per month, with no extra charges or commission. For a small business with fewer than 2 000 active contacts, this volume comfortably covers a weekly send.

Do I need consent from every contact?

Yes, except for communications strictly related to a purchase already made by that customer. For any commercial newsletter, the contact must have ticked a consent box, never pre-ticked.

How often do you recommend sending?

Three to four emails per month on average: enough to stay present, without tiring people. Adjust based on the unsubscribe rate from your first two or three sends.
