Email addresses inside Arabic interfaces

An email address can look intact in an Arabic confirmation message while its editing field still inherits right-to-left direction. Another screen can collect the address correctly but place nearby punctuation ambiguously or clip the domain on mobile. Those are separate defects with separate fixes.

For the ordinary Latin-script addresses used in this guide, give the displayed value an LTR boundary and put dir="ltr" directly on the email input. Keep Arabic labels, instructions and validation messages in the interface's RTL context. Then test the stored address, visible text and link destination independently.

The examples follow an artist residency portal. Applicants can update the address used for application correspondence and review it in a confirmation message. The fixture salma.studio+residency@example.org includes a dot and a plus alias, both worth preserving through editing, copying and link construction.

Fix the input's direction before changing the page#

An email input does not automatically become LTR simply because its type is email. Without an explicit direction, it can inherit RTL from the Arabic page.

Problem

<div dir="rtl">  <label for="correspondence-email">البريد الإلكتروني للمراسلات</label>  <input    id="correspondence-email"    name="correspondenceEmail"    type="email"    value="salma.studio+residency@example.org"  ></div>

The control's direction computes to RTL in the supplied browser checks. That does not mean every character in the address must appear reversed. It means the editable control has inherited a base direction that does not express this address field's intended LTR interaction.

Better

<div dir="rtl">  <label for="correspondence-email">البريد الإلكتروني للمراسلات</label>  <input    id="correspondence-email"    name="correspondenceEmail"    type="email"    dir="ltr"    autocomplete="email"    required    value="salma.studio+residency@example.org"  ></div>

The label remains Arabic and the control declares its own direction. autocomplete="email" is appropriate here because the applicant is updating their own contact address. An administrative field for somebody else's recipient address needs its own autofill decision.

The browser behavior supplied for this guide was measured in Chromium 151 on 2026-09-24. Repeat the interaction tests in supported Firefox and Safari versions; those engines were not part of the supplied measurements.

Do not make the entire form LTR to repair this one field. Other controls may collect Arabic titles or notes. MDN's dir reference describes element direction and inheritance.

Direction, alignment and keyboard choice are different#

dir="ltr" supplies the email control's direction. text-align positions its content within the box. A mobile keyboard layout is another concern, influenced by the input type and the browser. Treating those controls as interchangeable makes debugging harder.

For example, right-aligning the input does not establish LTR editing. Conversely, an LTR input does not require placing its Arabic label on the left side of the form. Keep the component's layout consistent with the Arabic interface and declare the value's direction at the control.

Prefer type="email" for the supported ordinary email-entry use case. It provides email-specific browser behavior and syntax validation. Adding inputmode="email" to a text input is not the same validation contract, and neither attribute is a replacement for dir.

Test the actual keyboard on representative mobile browsers. Do not promise an identical keyboard across devices. The important acceptance checks are that applicants can enter the address, reach the required punctuation and correct an error without fighting the field's direction.

Avoid dir="auto" as a workaround for a known LTR email format. It makes direction depend on the current contents, including invalid text the applicant may be in the middle of editing. An explicit policy is easier to verify for this field.

Also inspect shared CSS. A rule applying RTL to every input can contradict the attribute, while a universal LTR rule can damage Arabic text fields elsewhere. Fix the rule's scope rather than adding progressively stronger declarations to the residency email control.

A Latin address is not automatically a reversal example#

Do not assume that a string containing @, dots and a plus must visibly fall apart when placed after Arabic. A normal Latin-script address contains strong LTR letters. It is a different case from a phone number made of digit groups and spaces.

This unisolated message is a useful inspection fixture, but the address's presence alone is not proof of a visible failure:

<p dir="rtl">عنوان المراسلات: salma.studio+residency@example.org</p>

Inspect the address together with the actual sentence punctuation and neighboring content. If the problem report concerns brackets, a trailing full stop or a count after the address, retain that context in the reproduction. A different sentence can produce a different boundary problem.

Before calling an appearance broken, state what the Arabic reader should encounter: the localized message in its intended reading order and the address as one complete value, with its local part and domain in the recorded sequence. Then distinguish punctuation belonging to the message from punctuation belonging to the address.

The general boundary repair is straightforward:

<p dir="rtl">  عنوان المراسلات:  <span dir="ltr">salma.studio+residency@example.org</span></p>

This makes ownership explicit even when today's Latin address already looks intact. W3C's inline bidi markup guidance explains isolating inserted phrases and using an existing meaningful element when possible.

Do not describe the wrapper as reversing the address back. It establishes a direction boundary around normal bidi processing. The underlying email string should not change.

Keep sentence punctuation outside the address#

The plus alias and dots belong to the fixture address. A colon introducing it belongs to the Arabic label. A full stop ending the confirmation sentence belongs to that sentence. Keeping those responsibilities visible in markup makes the component reviewable.

<p dir="rtl">  ستصلك رسائل الإقامة على  <span dir="ltr">salma.studio+residency@example.org</span>.</p>

Inspect the full stop in the complete rendered sentence in each supported browser. This guide does not prescribe an exact visual result for every surrounding punctuation combination; its supplied browser rules do not enumerate arbitrary email-address sentences.

Do not move the full stop into the address element merely to alter its position. A copy helper using that element's text would then include punctuation that is not part of the mailbox. Fix the message's boundary or punctuation treatment while preserving the field's actual content.

Brackets deserve a separate fixture. If a design adds parentheses around a contact value, establish whether they are part of the message template or an intentionally grouped presentation of the value. Test the pair together, including adjacent Arabic words, rather than copying the visual position from an English screenshot.

Avoid hidden directional marks in the stored address as a punctuation repair. They become part of a string used by validation, copying or lookup. HTML already provides a place to express the displayed value's boundary. For longer mixed-language messages, see Arabic and English mixed text in HTML.

Put direction on a mailto link that owns the address#

When the address is already a link, use that element as the boundary:

<p dir="rtl">  عنوان المراسلات:  <a href="mailto:salma.studio+residency@example.org" dir="ltr">    salma.studio+residency@example.org  </a></p>

The visible address and destination must agree. The link's href does not establish direction for its text, and direction markup does not validate or repair the destination.

Keep the Arabic label outside the LTR link when the link's text is the address. If the clickable label is instead an Arabic action such as “Send a message,” that action label follows Arabic direction. Do not blindly assign LTR to every mailto: link regardless of its text.

Use a mailto: implementation that respects URI syntax. A fixed address with a localized subject can be constructed as follows:

const mailbox = "salma.studio+residency@example.org";const subject = encodeURIComponent("استفسار عن ملف الإقامة");const mailto = `mailto:${mailbox}?subject=${subject}`;

This example uses a known fixed mailbox; it is not an email validator for arbitrary external data. RFC 6068 defines the mailto scheme and the encoding requirements for its components.

Preserve the plus in the local part. Do not run form-style decoding over the mailbox and turn its plus into a space. Likewise, do not strip a plus alias or dots as part of an RTL fix. Those changes concern address identity and delivery policy, not presentation direction.

Check the generated destination string without sending a message to the fixture. If testing a mail client handoff, use an appropriate test environment and inspect the composed recipient and subject. A link that looks correct is not evidence that its destination was assembled correctly.

Separate the person's name from the mailbox#

A recipient display can contain both a person's name and an email address. Those parts have different direction policies. The name may be Arabic or Latin; the ordinary mailbox in this guide has a known LTR format.

Keep those fields structured rather than treating the entire display label as an email address:

<p dir="rtl">  المستلم:  <bdi>سلمى الشامي</bdi>  <span dir="ltr">salma.studio+residency@example.org</span></p>

The name can infer its direction independently. The mailbox keeps its explicit policy. If the design adds angle brackets or parentheses, test them in the final recipient component and decide which presentation unit owns them. Do not assume that an address fixture alone covers the combined display.

This display label is also different from what a single type="email" control accepts. A person-plus-address notation that looks familiar in a mail client is not automatically a valid value for a native email field. The portal should collect or select the name separately instead of asking the applicant to edit an assembled display string.

If the application later adds recipient chips or a multiple-address input, retain the same separation. Each chip should own its complete mailbox value. A comma separating recipients belongs to the list's representation, not to either individual address.

Do not split arbitrary recipient text using visual order or by assuming Arabic punctuation is interchangeable with the delimiters the control accepts. Decide the accepted entry format, explain it in Arabic, and test the resulting individual values. The HTML email state defines a comma-separated list when multiple is used; it does not turn the field into a general mail-header parser.

An editing component and a read-only recipient display can therefore use different structure while preserving the same mailbox. That is preferable to storing an Arabic display label where later code expects an address.

Placeholder and helper text should not become address data#

An email placeholder can show the shape of an address, while a visible Arabic label explains what the field is for. That keeps the editable LTR value separate from explanatory RTL prose.

<div dir="rtl">  <label for="residency-contact">البريد الإلكتروني للمراسلات</label>  <input    id="residency-contact"    name="residencyContact"    type="email"    dir="ltr"    autocomplete="email"    aria-describedby="residency-contact-help"    placeholder="salma.studio+residency@example.org"  >  <p id="residency-contact-help">استخدم عنوانًا يمكنك الوصول إليه.</p></div>

The placeholder is an example, not the applicant's saved value. Do not put invisible characters into value to position an Arabic placeholder or make an empty field look RTL. The field would then contain hidden data rather than being empty.

If the design requires Arabic placeholder prose, test that opposite-direction placeholder as its own text surface. A placeholder attribute cannot contain working child markup. Prefer moving substantial instructions to the label or helper text instead of making the placeholder carry both the explanation and an example address.

Keep the label visible after typing. Placeholder-only instructions disappear when the address is entered, precisely when the applicant may need to check which contact role the field represents.

Verify the empty, autofilled, pasted and saved states. A fixture that always starts with a Latin value can conceal an empty-state rule or helper-text styling issue. These checks concern the email component, not a reason to change the whole Arabic form.

Localize errors without confusing direction with validation#

type="email" supplies a browser syntax check. required establishes that an empty field is unacceptable for a required contact. dir="ltr" supplies presentation direction. None of these establishes that the mailbox exists or that a verification message can reach it.

The HTML email input specification defines the browser's email syntax and value handling. MDN's email input reference explains the control's practical use and validation behavior.

Do not assume lang="ar" makes every browser-generated error Arabic. The supplied browser checks show English native validation messages in an English Chromium installation even on an Arabic page. If the product requires Arabic errors, implement and test that requirement deliberately.

For a required email field, this small example localizes the missing-value and syntax-mismatch messages:

const emailField = document.getElementById("correspondence-email"); function updateEmailMessage() {  emailField.setCustomValidity("");  if (emailField.validity.valueMissing) {    emailField.setCustomValidity("أدخل بريدك الإلكتروني.");  } else if (emailField.validity.typeMismatch) {    emailField.setCustomValidity("أدخل عنوان بريد إلكتروني صالحًا.");  }} emailField.addEventListener("input", updateEmailMessage);emailField.addEventListener("invalid", updateEmailMessage);

Run it after the corrected correspondence-email input exists. It addresses those two constraints; an application adding other rules needs messages for those rules too. Clearing the previous custom error is necessary so a corrected address can become valid again. MDN's setCustomValidity reference explains that behavior.

Keep any separately rendered Arabic error in the form's RTL context. If an error quotes the submitted address, isolate that value just as you would in the confirmation message. Test correction as well as failure: a stale error after valid input is a distinct bug from wrong field direction.

Long addresses need layout handling as well as isolation#

The ordinary fixture may fit a desktop panel while a longer alias overflows a narrow confirmation card:

salma.studio+installation-residency-updates@example.org

Isolation does not shorten the address or guarantee that its container can shrink. Inspect both the text boundary and the component's sizing rules.

For a compact label-value row, one option is:

<p class="contact-row" dir="rtl">  <span>عنوان المراسلات:</span>  <a class="contact-address" dir="ltr"     href="mailto:salma.studio+installation-residency-updates@example.org">    salma.studio+installation-residency-updates@example.org  </a></p>

.contact-row {  display: flex;  gap: 0.75rem;} .contact-address {  min-inline-size: 0;  overflow-wrap: anywhere;}

The address keeps its direction boundary while the flex item can shrink and the text can wrap. MDN's overflow-wrap reference describes the wrapping behavior. Check the actual row at narrow widths; the example does not establish that every surrounding card has adequate space.

Do not insert literal spaces or manual line breaks into the stored address to create wrapping. That changes data to solve a presentation problem. Also inspect what users can read: clipping the domain can conceal which address will receive application correspondence.

If the design intentionally truncates the display, provide a way to inspect and copy the complete address. Test the visible shortened text and the full destination separately. For deeper container issues, use Arabic text overflow: causes and fixes.

Preserve the address across edits, copying and rendering#

Direction markup should not change the string submitted to the application. Keep one authoritative address value and let each renderer provide its own boundary.

A confirmation view should use escaped text rendering or textContent, not interpolate an applicant-supplied address into an HTML string. Isolation is not HTML sanitization, and escaping does not supply isolation. The component needs both appropriate text insertion and the intended direction structure.

For a copy-address action, use the authoritative address rather than scraping a whole sentence or a shortened display label. Copying the label-value row can include the label and punctuation; copying truncated visible text can omit part of the mailbox.

Check the plus alias and dots through the entire flow: enter, save, reload, display and copy. Do not let a cleanup helper remove them because an unrelated provider treats some aliases specially. Such a transformation is outside the direction fix.

Copy tests and visual tests answer different questions. A correctly copied value does not prove punctuation was placed correctly on screen, while a plausible screenshot does not prove the right value was saved. Retain assertions for both.

Test updates too. When an applicant changes the address after a failed submission, the input, confirmation text and link destination must all reflect the same current value. A renderer that updates only the visible label can leave the link pointing to the previous address.

Check masked addresses as a separate presentation#

The portal may conceal part of an existing contact address before an applicant edits or verifies it. That masked string is display content, not a replacement for the stored mailbox.

Test its actual characters and direction rather than assuming the full-address fixture covers it. Masking can remove strong letters or replace them with punctuation-like symbols, changing the directional evidence available inside an automatic boundary. An explicit LTR policy remains appropriate for a mask representing the ordinary LTR address format used here.

Keep the Arabic explanation outside that boundary. Review the domain and the mask together so the applicant can understand which contact address the interface refers to. Avoid describing an exact visual order for an untested mask; render the product's real output in its intended sentence.

Make the link and copy behavior match the presentation's purpose. If the view deliberately conceals the address, do not accidentally expose the complete mailbox through a mailto: destination, a tooltip or a copy action. A fully authorized edit view can offer different actions, but that should be an explicit product state.

When the applicant opens the editor, inspect which value populates the email input. It should follow the authorized editing flow, not submit the masked display string as though it were a valid mailbox. Include cancel, successful save and failed verification in the test cycle so the confirmation view cannot retain a stale mask for a previous address.

Internationalized email needs an explicit support contract#

The LTR policy in these examples concerns ordinary Latin-script addresses. It is not a claim that all possible email addresses contain only Latin characters.

Internationalized email can include non-ASCII content, and Arabic-script display introduces additional bidi considerations. Domain-name internationalization and a non-ASCII local part are also different capabilities. Supporting one does not establish support for the other.

RFC 6531 defines the SMTPUTF8 extension for internationalized email. That transport capability is separate from the syntax accepted by a particular HTML input and from the application's validation, storage, verification and delivery paths.

Do not advertise Arabic-script mailbox support because dir="auto" makes a sample look plausible. Verify the accepted representations through the complete system, including browser validation and mail handoff. Conversely, do not describe an ordinary ASCII address as invalid merely because it belongs to an Arabic-speaking applicant.

If internationalized addresses are in scope, create fixtures from the product's supported representations and review their reading order with appropriate language expertise. Avoid forcing an override onto the whole field to make one mixed-script example resemble its source string. A visual-order intervention does not create transport support.

Test the rendered field and message together#

Inspect the actual input, not just its outer wrapper:

const field = document.getElementById("correspondence-email");console.table([{  type: field.type,  dir: field.getAttribute("dir"),  computedDirection: getComputedStyle(field).direction,  value: field.value,  typeMismatch: field.validity.typeMismatch,  valueMissing: field.validity.valueMissing}]);

Run this on the corrected field. Then type, paste and edit the fixture address, including deleting and restoring the plus alias. Check the actual caret and selection experience in supported browsers.

Do not assume a caret automation written for type="text" can be reused unchanged. The HTML email state does not provide the same selection APIs, including setSelectionRange(). Use appropriate browser interaction tests rather than changing the input type solely to satisfy a test helper.

Exercise the same component on Arabic and English routes, and inspect its final DOM after dynamic rendering. A correct initial attribute can be lost if a later branch replaces the field or link. Record browser versions with visual evidence instead of assuming identical behavior from one engine's result.

A free Ritla scan can report R070, tel/email/url inputs rendered RTL (these must stay LTR). After repairing the email field, use Arabic and English mixed text in HTML for its confirmation messages or Arabic text overflow when a long mailbox does not fit its container.
