Right-to-left email design affects reading order as well as translation. Headings, product blocks, navigation, and directional icons may need different treatment, while prices, codes, and URLs can mix text directions within one line. Review the finished message on a phone and in actual email apps. A translated template is not ready until the layout communicates the same useful sequence.
Start with a simple structure
A clear single-column layout reduces unnecessary complexity. Keep headings, paragraphs, product details, and actions in an order that makes sense for the language. Avoid positioning meaning solely through left-versus-right placement.
Use Sendvio's language versions and verify the actual rendered direction rather than assuming the language selection fixes every component. Custom HTML blocks and copied content deserve particular attention because they may carry their own alignment or direction settings.
Separate reading direction from visual alignment
Moving a paragraph to the right edge does not necessarily establish the correct reading order for its contents. Direction affects how mixed-script text and punctuation are arranged; alignment affects where the line sits in its container. A template can look right-aligned and still display a product code or closing parenthesis incorrectly.
For a custom HTML component, ask the person responsible for the template to set and test direction deliberately, including any embedded text that runs the other way. Do not try to repair the display by manually reversing characters or adding spaces until one preview looks right. Those fixes can break when the name, price, or screen width changes.
Keep the content order sensible even before decorative positioning is applied. A product title, explanation, price, and action should remain understandable as a reading sequence. This is particularly useful when a client simplifies the layout or an assistive tool presents the content differently.
Inspect mixed content carefully
Check numbers, currency, punctuation, email addresses, and product names that remain in another script. A line can contain the right characters but display them in a confusing sequence. Have a capable reader inspect the result in context.
Do not mirror logos, product photography, or directional symbols automatically. Some elements retain their original meaning and orientation. Decide based on what each element communicates rather than applying a blanket visual flip.
Test the strings most likely to expose a problem
Build a small set of realistic examples: a local-language sentence containing an English product code, a price with a currency indicator, a phone number, and a personalized name. Inspect punctuation beside each value. A misplaced parenthesis or number may look minor to a non-reader while changing how the sentence is understood.
Keep codes and addresses copyable in their correct logical order. A customer should be able to copy a discount code from the message and use it successfully. Verify that the visible sequence, copied value, and destination all agree; a screenshot alone cannot establish that.
Check directional icons by meaning. An arrow that indicates moving to the next step may need different treatment from a product photograph or brand mark. Ask a fluent reviewer to use the email rather than merely approve its appearance. Their task is to explain what each action does and where they expect it to lead.
Test the sent message
Preview narrow and wide layouts, then send tests to relevant email apps. Check button labels, personalization, alternative text, and the destination after clicking. A translated email should lead into an understandable customer journey.
Keep the reviewer focused on both natural language and usability. Record any component that needs a different arrangement so the next campaign can reuse the tested pattern. The aim is a message designed for its reader, not an English layout with its text replaced and its font made smaller.
Maintain a tested example component for recurring mixed content, but retest it with the next campaign's actual values. A layout that handled one short product name may behave differently with a longer code or another currency. Solve the repeated component carefully so every future translation does not need a fresh visual workaround.
