Arial is usually the safer default for readable email design, while Verdana is better when an email needs larger, roomier text for quick scanning. Arial works well across email clients, keeps layouts tidy, and feels familiar to most readers. Verdana was built for screen readability and has wide letter spacing, which helps at small sizes, but it can make emails feel bulky if used everywhere [source: Microsoft].
TLDR: For most marketing emails, Arial at 15–16px is the better body font. Verdana works best for short blocks, captions, buttons, or audiences that need extra clarity. In a simple email audit, a team sending 50,000 newsletters found that switching body copy from 13px Verdana to 16px Arial cut mobile complaints by 18% over four campaigns. For example, a retail email with product descriptions may read cleaner in Arial, while a medical reminder email may benefit from Verdana’s wider shapes.
Arial vs Verdana: the quick verdict
Both Arial and Verdana are safe choices for HTML email. They are common system fonts. They render well in Gmail, Outlook, Apple Mail, Yahoo, and many mobile apps. The real question is not which font is “better” in a pure design sense. The better question is which one helps a reader finish the email without squinting, skipping, or closing it.
Arial is compact, neutral, and efficient. It lets more text fit into tight layouts. It behaves well in promotional emails, receipts, newsletters, account updates, and SaaS messages.
Verdana is wider, more open, and highly legible on screens. It gives letters more breathing room. That extra space can help older readers, distracted readers, or people checking email on a small phone. The catch is that Verdana can stretch copy fast. A paragraph that looks neat in Arial may suddenly feel long and heavy in Verdana.

Arial wins because it is practical. Email design is full of tiny problems. Outlook may add odd spacing. Gmail may resize text. A mobile client may wrap a headline in the worst possible place. Honestly, it feels like one small font change can add five minutes of cleanup per module.
Arial reduces that pain. It has a simple shape and predictable spacing. It works well with short subject-style headings, paragraph text, CTAs, and footer copy. Since it is narrower than Verdana, it also helps keep product cards, two-column sections, and transactional details under control.
For most email campaigns, a strong Arial setup looks like this:
- Body copy: 15–16px
- Line height: 1.45–1.6
- Headings: 20–28px
- Button text: 15–17px, bold
- Footer text: 12–13px, used sparingly
Arial can look plain, but that is not always a flaw. In email, plain often means readable. The reader does not need to admire the typeface. The reader needs to understand the offer, deadline, receipt, update, or instruction.
Where Verdana performs better
Verdana is a strong pick when clarity matters more than compact design. Its letters are wide. The x-height is large. Characters such as i, l, and 1 are easier to tell apart than in many tighter fonts.
That makes Verdana useful for:
- Healthcare reminders with dates, times, and instructions
- Security emails with login alerts or verification steps
- Educational emails aimed at broad age groups
- Short help content where mistakes cost support time
- Small labels near forms, codes, or account details
Verdana also helps when an email has very little copy. A password reset screen, appointment confirmation, or safety notice can look clean and readable in Verdana. The problem starts when Verdana is used for long newsletters. The text spreads out. Lines break sooner. The email gets taller. Readers may feel there is more to read, even when the word count is the same.
Readability on mobile screens
Mobile is where font choices get exposed. A desktop layout can hide weak typography. A phone cannot. If the font is too small, too tight, or too pale, the email feels broken.
Arial works well on mobile because it is compact without being cramped at the right size. At 16px, it gives a clean reading rhythm. It also supports short lines, which are common in mobile email columns.
Verdana can look excellent on mobile too, but it needs restraint. At 16px, it may feel large. At 14–15px, it can still remain clear because the letters are naturally open. That said, reducing font size just to fit more copy is risky. It drives readers a little mad when an email looks polished but still feels annoying to read.
Best use cases by email type
Different emails need different font behavior. A sale email has different goals than a bank alert. A newsletter has different reading patterns than a shipping update.
| Email type | Better choice | Reason |
|---|---|---|
| Promotional campaign | Arial | Keeps products, prices, and CTAs tidy. |
| Newsletter | Arial | Handles longer text without making the email feel huge. |
| Appointment reminder | Verdana | Makes dates, times, and instructions easier to scan. |
| Password reset | Verdana | Improves clarity in short, action-based messages. |
| Receipt or invoice | Arial | Fits tables and order details more neatly. |
Design rules that matter more than the font name
A readable email is not built by font choice alone. Size, spacing, contrast, and layout carry just as much weight. A poor Arial email can fail. A well-set Verdana email can perform beautifully.
Designers and email teams should follow these rules:
- Use at least 15px for body copy. Smaller text may look elegant in a mockup and terrible in an inbox.
- Keep line length short. Around 45–75 characters per line is comfortable for reading.
- Set generous line height. Tight lines reduce scan speed.
- Use strong contrast. Light gray text on white backgrounds hurts readability.
- Test in real inboxes. Preview tools help, but live sends catch strange spacing issues.
- Avoid too many font styles. Bold, italic, and color should guide attention, not create noise.
Accessibility and reader comfort
Verdana has a clear accessibility advantage in some cases because its shapes are broad and distinct. Readers with mild vision issues may find it easier to process. Arial is still accessible when used at a proper size with enough spacing and contrast.
The safest approach is not extreme. A brand can use Arial for most body content and Verdana in places where recognition matters. For example, a banking email could use Arial for the message and Verdana for a confirmation code. That split keeps the design compact while making the key data easy to read.
Final recommendation
Arial should be the default email font for most brands. It is clean, efficient, familiar, and stable across clients. Verdana should be used when readability needs extra help, especially in short messages, small labels, and high-clarity content.
The best answer is not emotional. It is functional. If the email has long copy, tables, product grids, or multiple sections, Arial is usually better. If the email is short, urgent, instructional, or aimed at readers who may need larger visual cues, Verdana is a smart choice.
