How to Add Emojis to Email Subject Lines and Body

Why Use Emojis in Email

Emojis in email subject lines can increase open rates by standing out in a crowded inbox. A single well-chosen emojiEmoji

acts as a visual anchor โ€” โœˆ๏ธ for a travel newsletter, ๐Ÿ”ฅ for a sale, ๐Ÿ“… for a calendar reminder. They also convey tone at a glance, making the subject line feel warmer or more urgent.

In the email body, emojis can break up long text, highlight key points, and reinforce your brand's voice. This guide covers how to insert emojis in all major email clients, how they render across platforms, and what to avoid.

Method 1: Copy and Paste (Works Everywhere)

The most reliable method for any email client is to copy an emoji from a reference site and paste it into your subject line or body.

  1. Find the emoji you want โ€” use EmojiFYI's Emoji Keyboard or search on your phone's emoji picker
  2. Copy it to your clipboard
  3. Open your email compose window
  4. Paste with Ctrl + V (Windows/Linux) or Command + V (Mac)

This works in Gmail, Outlook, Apple Mail, Yahoo Mail, Thunderbird, and virtually every webmail interface because all modern email clients support UTF-8UTF-8

text.

Method 2: Using Your OS Emoji Picker

Gmail in a Browser (Mac)

Press Control + Command + Space to open the macOS Character Viewer, then click any emoji to insert it at your cursor position inside the Gmail compose window.

Gmail in a Browser (Windows)

Press Windows + . (period) or Windows + ; (semicolon) to open the Windows emoji picker, then click to insert.

Gmail in a Browser (Linux)

Use Ctrl + Shift + E (GNOME/IBus) or the UnicodeUnicode

hex input method (Ctrl + Shift + U โ†’ hex code โ†’ Enter).

Outlook Desktop App (Windows)

  1. Place your cursor in the subject line or body
  2. Press Windows + . to open the emoji picker
  3. Click an emoji to insert it

Alternatively, go to the Insert tab โ†’ Symbol โ†’ More Symbols, then set the font to Segoe UI Emoji and browse the character map.

Apple Mail (Mac)

Click in the subject or body field, then press Control + Command + Space to open the Character Viewer.

Method 3: HTML Email and Emoji Entities

If you are sending HTML-formatted email via an ESP (Email Service Provider) like Mailchimp, Klaviyo, or HubSpot, you can embed emojis using UTF-8 characters or HTML numeric entities.

Direct UTF-8 in HTML Templates

<h1>๐Ÿ”ฅ Flash Sale โ€” 50% Off Today Only!</h1>
<p>Don't miss out โฐ โ€” offer expires at midnight.</p>

Ensure your HTML email template includes the UTF-8 charset declaration:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

HTML Entities as a Fallback

If your template editor strips non-ASCII characters, use hex entities:

<h1>&#x1F525; Flash Sale โ€” 50% Off Today Only!</h1>
Emoji Hex Entity Description
๐Ÿ”ฅ &#x1F525; Fire (urgency/sale)
โœ… &#x2705; Check mark (confirmation)
๐Ÿ“ง &#x1F4E7; Email
โญ &#x2B50; Star (featured)
๐ŸŽ‰ &#x1F389; Party popper (celebration)

Emoji Rendering in Email Clients

Emojis in email are rendered using the recipient's operating system emoji fontEmoji Font

, not a font you specify. This means the same emoji can look noticeably different across clients:

Client Emoji Font Visual Style
Apple Mail / iOS Mail Apple Color EmojiColor Emoji
Full-color emoji rendered using bitmap images or color vector graphics, as opposed to monochrome text-style rendering.

Slightly different shapes

For business emails, check how your chosen emojis look on the platforms your audience uses. Emojis that look friendly on Apple devices may appear flat or different on Windows. Stick to universally understood emojis like โœ…, โญ, ๐Ÿ”ฅ, and โค๏ธ rather than obscure ones whose appearance varies significantly.

Best Practices for Email Subject Lines

Dos

  • Place the emoji at the start or end of the subject line: ๐Ÿ”ฅ Summer Sale Starts Now or Summer Sale Starts Now ๐Ÿ”ฅ
  • Use one emoji maximum in most subject lines โ€” two at most for promotional emails
  • Match the emoji to the tone: ๐ŸŽ‰ for celebrations, โš ๏ธ for warnings, ๐Ÿ“ฃ for announcements
  • Test in multiple clients before sending to your full list

Don'ts

  • Do not use emojis in every email โ€” they lose impact quickly
  • Avoid emoji strings like ๐Ÿ”ฅ๐Ÿ’ฏ๐ŸŽฏโœจ โ€” looks spammy to both humans and spam filters
  • Do not use emojis whose meaning is ambiguous or platform-inconsistent as the primary message signal
  • Do not rely on an emoji alone to convey critical information (it may not render)

Subject Line Examples by Category

E-commerce / Sales

๐Ÿ”ฅ Last chance: 40% off ends tonight
โณ Only 3 hours left โ€” Flash Sale
๐Ÿ›’ Your cart misses you

Newsletters / Content

๐Ÿ“ฐ This week in tech: AI takes over everything
๐Ÿ“š 5 books we loved this month
๐ŸŒ How this city changed its transportation forever

Transactional / Notifications

โœ… Your order has shipped!
๐Ÿ“ฆ Your package is out for delivery
๐Ÿ”‘ Your account password was changed

Events / Invitations

๐Ÿ“… You're invited โ€” join us on March 15th
๐ŸŽ‰ It's almost time! Your event starts tomorrow

Handling Clients That Don't Render Emojis

A small percentage of email clients โ€” some older Outlook versions and corporate mail clients โ€” may not render emojis at all, showing a square (โ–ข) or nothing. To handle this gracefully:

  • Write subject lines that work even without the emoji: ๐Ÿ”ฅ Sale ends tonight still reads as Sale ends tonight if ๐Ÿ”ฅ is dropped
  • Do not use an emoji as the only indicator of meaning โ€” always include text
  • Place emojis at the beginning or end where their absence is least disruptive

Testing Your Emails with Emojis

Before sending, test how your emoji-rich email renders across clients:

  1. Send a test to yourself and open it on iOS, Android, and a Windows PC
  2. Use email preview tools like Litmus or Email on Acid to see renders across 90+ clients
  3. Check your spam score โ€” too many emojis can raise spam filter flags
