If you repeatedly type the same email address, phone number, or mailing details on your Mac, save each as a text replacement: a short trigger you type that expands to the full text. Go to Apple menu > System Settings > Keyboard > Text Replacements, add a trigger and its replacement, then use it in a compatible app. Choose triggers that are easy to remember and unlikely to appear in ordinary writing; text replacements are not available in every app. Apple’s Mac guide to replacing text

Choose which contact details to automate

Start with details you enter frequently and that are stable enough to keep as shortcuts. An email address is a straightforward candidate. You might also add a phone number, a business mailing address, or a standard sign-off. Make a separate entry for each item you want to insert; macOS replaces one trigger with its corresponding text, so there is no need to bundle unrelated information together.

For example, you could use ;eml for your email address and ;tel for your phone number. These are illustrative trigger names, not reserved Mac commands. Pick a pattern you can remember and avoid short everyday strings such as me or home, which could appear in ordinary text. The trigger should be quicker to type than the full detail, while distinctive enough to reduce accidental expansion.

Before adding a detail, check its spelling, punctuation, spacing, and currentness. An address replacement is only as accurate as the text saved in it. For a phone number, choose the format you normally share, including country code or punctuation if needed. Do not put information in a replacement that you would not want expanded into a message or document by mistake.

Add a text replacement in macOS

  1. Open the Apple menu and choose System Settings.
  2. Select Keyboard in the sidebar. Scroll if needed.
  3. Click Text Replacements.
  4. Click the add button, enter the trigger in the text-to-replace field and the full email or contact detail in the replacement field, then click Add.
  5. Click Done.

Apple documents these controls and the option to open text settings from an app through Edit > Substitutions > Show Substitutions > Text Settings. The wording and layout around Keyboard settings may vary by macOS release, but the documented path is through Keyboard settings. Apple’s setup instructions

Create distinct entries for distinct pieces of information. For example, ;eml might expand to a work email, while ;mail might expand to a postal address. If you need a different format for a particular audience, save another clearly named trigger only if you will remember which version to use; otherwise, insert the detail and edit it in context.

Use and check a replacement

In an app that supports text replacement, type the trigger where you want the detail to appear. Check the result before sending or saving, especially when the message concerns a contact detail: confirm that the entire trigger was replaced and that the expanded text is correct. Apple notes that text replacements are not available in all apps, so a trigger that works in one text field may not expand in another. Apple’s guide explains app support and substitutions

If a replacement does not occur, first check that the trigger matches the saved entry and that the app supports text replacement. In an app with the relevant menu, choose Edit > Substitutions and look for Text Replacement; a checkmark indicates it is enabled. Apple also documents using Show Substitutions to apply a replacement to selected existing text or to all text in a document. Those commands depend on the app exposing the menu and are not a universal fix for unsupported apps.

A text replacement inserts text. It does not validate an email address, look up a person’s current phone number, choose a recipient, or send a message. Use the expanded text as a typing aid, then verify the recipient and detail yourself. For a one-time or variable detail, typing or pasting the current value may be safer than relying on a saved entry.

Pick triggers that are easy to remember and safe to type

Use a consistent prefix to make triggers easier to recognize. A punctuation prefix such as a semicolon can make a trigger less likely to occur in ordinary prose, though it is a convention you choose rather than a special feature. Keep the rest mnemonic: ;eml, ;tel, and ;addr are easier to associate with their contents than arbitrary strings.

Avoid triggers that are common words, names, or sequences you may type inside an email address. A trigger that expands unexpectedly can disrupt a message or form, and contact details can be sensitive when inserted in the wrong place. If a trigger causes trouble, open Keyboard > Text Replacements, select the entry, and remove or change it. Then check any other saved entries for similar triggers.

A quick design check before saving an entry is to ask: Can I recall this trigger without looking it up? Is it unlikely to appear in ordinary text? Does the replacement contain exactly the information I intend to share? If the answer to any is no, revise the trigger or replacement before using it.

Back up or sync your replacements

Apple says you can export selected replacements by opening System Settings > Keyboard > Text Replacements, selecting entries, and dragging them to the desktop. This creates a property list.plist file that can be copied elsewhere as a backup or shared. To import, drag that file into the Text Replacements window on the Mac and click Done. The export is a file you manage; keep it somewhere you can find if you need it. Apple’s backup and sharing instructions

Apple also documents using iCloud to keep text replacements up to date across Apple devices: set up iCloud Drive and sign in with the same Apple Account on each device. If you prefer to keep replacements on the Mac, exporting a backup is a separate option. Apple’s backup and sharing instructions

Keep the list accurate

Review entries when an email address, phone number, or address changes. Edit or remove outdated replacements in the same Text Replacements settings window, and update any backup file you maintain. A stale shortcut can produce a plausible-looking but incorrect contact detail, so treat each entry as stored text that needs occasional upkeep.

Wallo is relevant when these shortcuts are part of a broader Mac work session: it organizes open windows and to-dos locally by goal, with keyboard focusing. It does not create text replacements or alter how macOS expands them.
