Choosing a font size for email marketing is not just a matter of picking a number. Readers need type that stays legible on phones, supports quick scanning, and fits the message and brand. Of these two books, Email Marketing Rules is my practical pick for marketers who want subscriber-experience guidance, while Why Fonts Matter is the stronger choice for understanding typography, readability, and brand perception. Neither is a dedicated font-size manual, so the central tradeoff is breadth: email strategy with limited typography detail versus deeper design theory with less hands-on email instruction.

I rank these books by how directly they can help a reader make email decisions. Email Marketing Rules comes first because its subject is the email experience itself; Why Fonts Matter follows for its useful typography foundation. If you need exact size recommendations, responsive templates, or testing instructions, neither title alone fills that gap. I explain what each can contribute—and where you will need more specific guidance—below.
Key Takeaways
- Email Marketing Rules ranks first for email marketers because its focus is the subscriber experience, although the supplied description does not promise specific font-size instructions.
- Why Fonts Matter is the stronger typography-theory choice, covering readability, perception, and brand identity rather than email execution.
- Neither listing provides a confirmed font-size chart, email coding instructions, or practical exercises, so readers seeking exact settings should pair a book with hands-on email testing.
- Choose the email-focused book for a broader campaign and subscriber perspective; choose the typography book when design reasoning is the main learning goal.
- The best size depends on the email’s audience, device, typeface, and layout; a readable result should be checked on mobile as well as desktop.

Email Marketing Rules: 184 Best Practices to Optimize the Subscriber Experience and Drive Business Success
Email Marketing Rules is my first pick for readers who want font decisions to sit within the wider subscriber experience. Its described scope is email marketing best practices, so it is a more direct match for campaign planning than Why Fonts Matter, whose focus is typography as a design and communication discipline. That broader email perspective can help marketers think about whether a message is easy to consume, not just whether a typeface looks on-brand.
The limitation is equally clear: the supplied description does not identify a font-size section, recommended point sizes, mobile rules, or email-building tools. I would not buy this as a stand-alone technical answer to “what size should my email text be?” Instead, I see it as the more relevant of the two for marketers building a subscriber-centered approach, with font choices treated as one part of the reading experience. Compared with Why Fonts Matter, it offers stronger email relevance but less explicit typography depth.
That distinction makes this a sensible choice for email managers who need broad practices to guide campaign decisions and can verify typography separately. Readers who want visual examples and a deeper account of why fonts affect perception may get more from Why Fonts Matter. The available description also leaves the book’s practical tools unspecified, so buyers should not assume it includes templates or exercises.
Pros:- Focuses directly on email marketing rather than design in general.
- Frames decisions around the subscriber experience.
- Covers a broad collection of email marketing practices.
- Pairs naturally with separate testing of type size across devices.
Cons:- The supplied description does not confirm specific font-size recommendations.
- No particular tools, templates, or implementation features are listed.
- Offers less explicit typography theory than Why Fonts Matter.
Best for: Email marketers who want subscriber-experience and campaign guidance around which to build their own typography decisions.
Not ideal for: Readers who need a dedicated email font-size chart, coding directions, or confirmed hands-on typography exercises.
- ASIN:B0BW23B5JG
- Title:Email Marketing Rules: 184 Best Practices to Optimize the Subscriber Experience and Drive Business Success

- Described emphasis:Subscriber experience and business success
- Practice count in title:184

Our verdict“Choose this first for an email-centered learning resource, but supplement it with device testing if you need concrete font-size decisions.”
Why Fonts Matter
Why Fonts Matter is the better match when the reader’s main question is why one typographic choice feels clearer or more appropriate than another. Its described coverage of readability, perception, and brand identity gives marketers a conceptual basis for thinking about the role of type in an email. That is more directly about typography than Email Marketing Rules, even though it is less specific to email campaigns.
The book’s strength is also its tradeoff. A guide exploring typography broadly may help readers judge visual hierarchy and brand fit, but the supplied description does not promise email-specific size settings, responsive guidance, or practical exercises. It may also be too advanced for beginners. Compared with Email Marketing Rules, this title gives more design-oriented context but leaves more work for the reader to translate that context into an email template.
I would choose it for a designer or marketer who wants stronger typography literacy before making layout decisions. It is a weaker fit for someone who needs a quick operational checklist for campaigns. The listing notes high-quality visual examples, which can support visual learning, but examples alone do not replace checking how a message renders on a recipient’s phone, tablet, or desktop screen.
Pros:- Explores how typography influences readability and perception.
- Connects font choices with brand identity.
- Includes high-quality visual examples, according to the supplied description.
- Offers more explicit typography focus than Email Marketing Rules.
Cons:- May be too advanced for beginners.
- The described scope is not specific to email marketing.
- The supplied description notes limited practical application exercises.
Best for: Design-minded marketers and designers who want to understand how typography affects legibility, brand character, and communication.
Not ideal for: Beginners seeking a simple email-size rule or marketers who need specific campaign procedures and implementation exercises.
- ASIN:1584236310
- Title:Why Fonts Matter
- Stated scope:Typography in design and communication
- Topics described:Perception, readability, and brand identity
- Visual material:High-quality visual examples, according to the supplied description
- Email-specific guidance:Not specified in the supplied description
- Practical exercises:Limited, according to the supplied description
- Beginner suitability:May be too advanced for beginners
Our verdict“Pick this for a deeper design foundation, not as a ready-made email font-size guide.”
How We Picked
I compared the books against the search intent behind font size for email marketing: readers want help making type readable and useful in real email campaigns. I gave the first ranking priority to direct relevance to email, then looked at whether the book’s described subject can inform decisions about legibility, brand fit, or subscriber experience. I also weighed the limits visible in the supplied descriptions instead of treating either title as a specialized font-size reference.
Email Marketing Rules earns the leading position because it addresses email marketing and subscriber experience directly. That makes it a more natural starting point for a campaign practitioner, even though its description does not name typography tools, font-size guidance, or specific implementation features. Why Fonts Matter ranks second because its typography focus is more direct, but its broader design scope and potentially advanced treatment may require readers to translate ideas into email layouts themselves.
I did not infer unlisted contents, editions, formats, or measurable outcomes. The supplied specifications include only an ASIN for the first book and no additional specs for the second, so I keep those fields limited to known information. This is a comparison of the described books as learning resources—not a claim that either one provides a definitive font size. For that, readers should check their own templates and audience across devices.

Factors to Consider When Choosing Font Size For Email Marketing
These two books address different parts of the question. One starts with email practices and subscriber experience; the other starts with typography and communication. I would choose based on whether you need campaign context or design understanding, then confirm actual email legibility in the tools and devices your audience uses.
Separate general typography knowledge from email-specific instructions
A book about typography can explain why size, typeface, spacing, and hierarchy affect reading, but that does not automatically translate into a tested email setting. Why Fonts Matter is the more direct resource for those design concepts. Email Marketing Rules is more relevant to email as a channel, yet its provided description does not confirm a font-size chapter or exact recommendations. If a listing does not state a size chart or email implementation method, I would not assume one is included.
Think about the reader’s screen and reading conditions
Email may be opened on a small phone display, a large desktop monitor, or somewhere in between. A font that appears comfortable in a desktop preview may feel cramped on a phone, especially when lines are long or the layout is dense. I recommend checking the rendered email at multiple widths and reading the actual copy at normal viewing size. A numeric setting is only a starting point; typeface, line spacing, contrast, and column width all affect how large text feels.
Choose the book that addresses your current knowledge gap
If you already understand design basics but want a broader framework for email decisions, Email Marketing Rules is the more natural starting point. If you know campaign mechanics but want to reason better about font character and readability, Why Fonts Matter offers the stronger match. I would avoid buying both simply because the topic contains the word “font”: the books have different scopes, and neither description confirms a complete email typography workflow.
Use testing to turn principles into a usable size
Once you choose a type size, review a real campaign in the email client previews or device checks available to you. Look for body copy that can be read without zooming, headings that form a clear hierarchy, and links that remain easy to tap. Ask a colleague to scan the message on a phone as well as a desktop, or compare versions when your email platform supports testing. This practical check complements the theory in Why Fonts Matter and the subscriber-centered outlook of Email Marketing Rules.
Check what a product description actually confirms
For this pair, the available details are limited. The typography book is described as having visual examples and limited application exercises; the email book is described as a collection of 184 best practices, without named tools or specific font features. I have kept the specifications to those stated details rather than filling gaps with assumptions. If you need a technical manual, look for a resource that explicitly names responsive email typography, accessibility, coding, or tested size recommendations.
Frequently Asked Questions
Which of these books is more useful for choosing a font size for email marketing?
Email Marketing Rules is the closer fit for someone working on email campaigns because its subject is email practices and the subscriber experience. However, the supplied description does not confirm exact font-size advice. Why Fonts Matter discusses readability and typography more directly, but its scope is not described as email-specific. Choose based on whether you need email context or typography fundamentals, and do not treat either description as proof of a ready-to-use size chart.
Does either book list a recommended email body-text size?
The supplied descriptions do not name a recommended body-text size for either title. They also do not confirm a chart of sizes for headings, mobile layouts, or email templates. If you need an exact setting, check the full book contents before purchase or consult an email resource that specifically covers responsive typography. Whatever starting size you use, inspect the message on the screens and email clients relevant to your subscribers.
Should I start with typography theory or email marketing practices?
Start with Email Marketing Rules if your main need is an email-oriented view of subscriber experience and campaign practices. Choose Why Fonts Matter if your main gap is understanding how typography shapes readability, perception, and brand identity. The first has stronger channel relevance; the second has a clearer typography focus. A marketer who already knows one area may benefit more from the other book than from reading two resources with overlapping strengths.
Is Why Fonts Matter suitable for a beginner?
The supplied description says it may be too advanced for beginners and notes limited practical application exercises. That makes it a less straightforward first step for someone who wants simple instructions for setting up an email. Its visual examples and discussion of readability and brand identity may still interest a design-minded learner, but readers who prefer step-by-step campaign guidance may find Email Marketing Rules more approachable by subject matter.
How can I tell whether my email font size is readable?
Preview the message on both a phone and a desktop-sized screen, then read it at ordinary viewing distance without zooming. Check whether paragraphs are comfortable to scan, headings stand apart from body copy, and links are easy to identify and tap. Also review line length, spacing, contrast, and the typeface itself, since these can make identical font sizes feel different. Use a colleague or a small audience test when possible rather than relying only on a design preview.
Conclusion
For an email marketer who wants a channel-focused starting point, I recommend Email Marketing Rules: it centers on email practices and subscriber experience, though it is not confirmed as a font-size manual. For a designer or marketer seeking stronger typography fundamentals, Why Fonts Matter is the better fit, with its emphasis on readability, perception, and brand identity. Beginners who need specific instructions should be cautious about the latter’s advanced scope and limited exercises. Whichever book you choose, verify your type in real email previews; the best size is the one your audience can read comfortably across its devices.
