Every modern newsletter is HTML, whether you write the code yourself or let an editor write it for you. What matters for a Belizean audience is how that HTML behaves on the phones most of your readers use, sometimes on a slow mobile connection out on the cayes or in rural villages. This page covers both routes and the details that make the difference.
Two ways to produce HTML in Mailpro
Let the editor write it
The drag-and-drop editor produces clean, responsive HTML from blocks you arrange visually. This suits most shops, hotels and associations: no code to maintain, and every template is already tested across email clients.
Bring your own code
If a developer or agency has built a branded design, import the HTML as a file or paste it in. Mailpro adds tracking and the unsubscribe mechanism when you send.
Mobile first, not mobile also
DataReportal counted 345,000 mobile connections in Belize in early 2025, equal to 82.2 percent of the population (Digital 2025: Belize). Treat the phone as the main screen:
- Single-column layout: multi-column tables that collapse badly are the most common failure.
- Light images: compress photos. A 3 MB reef panorama that looks beautiful on office Wi-Fi may not load on a weak mobile signal.
- Live text, not text in images: prices, dates and calls to action should be real text, so they display even when images are blocked and can be read by screen readers.
- Tap-sized buttons: large buttons with plenty of space around them.
Mailpro’s responsive design handles most of this automatically for template-based newsletters.
Bilingual HTML without the mess
Readers in Orange Walk, Corozal or Cayo may prefer Spanish, while your visitor list reads English. There are two clean options. You can send separate English and Spanish versions based on a language field, which is usually best. Or, for short local announcements, you can use a single email with the two languages in clearly separated blocks. Avoid alternating languages sentence by sentence, which is tiring to read in either language.
Technical checklist before sending
- Inline your CSS. Many email clients ignore style blocks in the head.
- Give every image alt text, especially the logo and the main offer.
- Keep the total HTML size moderate. Gmail clips very long messages and hides the rest behind a link.
- Declare UTF-8 so accents in Spanish names and places (Belmopán, Benque Viejo del Carmen) display correctly.
- Include a footer with your business name, address, contact details and unsubscribe link. Belize’s Electronic Transactions Act, 2021 requires online sellers to identify themselves, and mailbox providers expect the unsubscribe link.
- Send tests to Gmail, Outlook and an iPhone before the real send.
Dark mode and images
Many phones display email in dark mode, which can invert colours and make a dark logo on a transparent background disappear. Test your design in dark mode, give logos a light outline or a solid background, and check that the text remains readable. Our page on dark mode in newsletters explains what to look out for.
Personalise the HTML
Merge fields can go anywhere in the code: a greeting, a booking reference, a store address or the language of a section. See newsletter personalization. For the full workflow from idea to send, read how to create a newsletter, or return to newsletter creation in Belize.
