Customer.io serves a diverse, global audience, and it's essential to craft content that resonates with everyone. When creating content, keep in mind the following guidelines to ensure that regional idioms, slang, puns, wordplay, and cultural references are relevant and inclusive for all readers.

Minimize regional idioms and slang. Avoid using idiomatic expressions or slang that might be specific to a particular region. Only use universal language. Instead of saying, "Let's hit the ground running," use "Let's get started."

Use puns and wordplay with caution. Be cautious when using puns or wordplay, as they can be challenging to translate or understand for non-native English speakers. Instead of "Our product is a real game-changer," use "Our product is innovative."

Explain cultural references. If you must use cultural references, provide a brief explanation to ensure that readers from different backgrounds can grasp the context. "Our team works like a well-oiled machine, meaning we're highly efficient and coordinated."

Writing style

Knowledgeable and approachable. We're industry experts with over a decade of experience. Our content should reflect this expertise, but it should also be easily digestible. We aim to educate our customers without overwhelming them with technical jargon or condescending language.

Helpful and empathetic. Every piece of content should offer real value and guide our audience in overcoming their challenges. We understand our customers have technical proficiency, but we are the experts and it's our responsibility to provide clear, step-by-step guidance. People should be the focal point of our writing, not merely abstract concepts.

Transparency and conciseness. We believe in transparency and straightforward communication. We'll always provide information as it is, avoiding unnecessary complexity. We respect our customers’ time and strive to deliver concise and actionable content.

Active voice. Active voice helps us communicate more clearly and concisely, ensuring that the subject of the sentence performs the action, making it easier for our audience to understand.

Punctuation rules

Colons (:)

Use a colon to introduce a list or provide emphasis.

Our platform includes three core components: marketing automation, customer data, and analytics.

Commas (,)

Commas are used for a variety of purposes, including separating items in a list and setting off non-essential clauses. Use the Oxford comma (serial comma) in lists to separate the final item from the preceding ones with a comma.

List

Our services include email marketing, automation, analytics, and reporting.

Non-essential clause:

Our marketing team, led by Jason, delivered outstanding results.

Semicolons (;)

Use semicolons to join two closely related independent clauses (sentences) or to separate items in a list when those items themselves contain commas. Use semicolons sparingly.

Joining clauses:

The campaign was a success; our engagement rates skyrocketed.

List with items containing commas:

Our global team includes members from New York, NY; London, UK; and Sydney, Australia.

Hyphen (-)

A hyphen is a short punctuation mark used to join words or parts of words, often to create compound words or clarify the meaning of a phrase.

Our marketing automation platform provides real-time data analysis for customer engagement.
Our email campaign will run from October 1-31 for maximum customer engagement. Note: en dash is the accurate punctuation to use in this example, but a hyphen is used here as it is more commonly used than an en dash.

Em dash (—)

An em dash is a longer punctuation mark used to set off a clause or phrase for emphasis. They are often used in place of parentheses and commas (and sometimes semi-colons).

“Customer engagement is our top priority,” shared Colin Nederkoorn, CEO and Founder of Customer.io.

Capitalization

Use sentence case (only capitalize the first word) for headings, subheadings, and bullet points.

Messaging automation that activates customer data

Capitalize proper nouns, including product names, such as Customer.io, Journeys, and Data Pipelines.

Data Pipelines integrates with Salesforce, HubSpot, and Mixpanel.

Acronyms

Always introduce an acronym by writing it out fully the first time you use it, followed by the acronym in parentheses ( see list here ). The exception to this rule is when using acronyms that are industry-standard terms, such as API.

Click-through rate (CTR) is a form of measurement for your messaging campaigns.

Always write out Customer.io in external and public-facing content. CIO or C.io should only be used internally for informal writing, such as Slack.

Contractions

We support the use of contractions. They’re totally acceptable!

Numbers

Always spell out numbers that begin a sentence and through the number nine. Anything 10 and above is written in numeric form. The exception to this is using numerals under 10 in headers (5 Marketing automation best practices).

When using ordinal adverbs, write the number out in full.

Customer.io relies on first-party data (not 1st-party).

When referencing time, put a space between the number and am or pm. Time is an exception to the rule above where you can use the numeral through nine.

The webinar starts at 1 pm today and ends at 2:30 pm.

Subject-verb agreement

Subjects and verbs agree in number (singular or plural).

🟢 The marketing team is working on a new campaign (singular)

Note: Data Pipelines is a singular subject. Example:

Formatting and structure

To create structured content, employ headings, subheadings, bullet points, and numbered lists. Break information into scannable sections, using proper hierarchy to guide readers. Maintain consistent formatting, style, and layout across all content types. Consider incorporating visual aids like tables and infographics for enhanced understanding.

Use short sentences and paragraphs for improved readability and comprehension.
Break up text with headings, subheadings, and bullet points to enhance scannability. For longer blog posts and emails, utilize h2s, h3s, and h4s.
Ensure consistent formatting style for various content types, such as blog posts, emails, and knowledge-base articles.
Employ numbered lists for step-by-step instructions or processes.
Utilize bold or italics sparingly to highlight important points or emphasize specific words.

Lists

When using complete sentences for your lists, always use end punctuation. Use bolded words or phrases at the beginning of the sentence to emphasize key terms or points. It enhances readability and the visual hierarchy of information, helping readers quickly grasp key concepts (also good for SEO).

When creating lists, it's essential to maintain parallelism to ensure consistency and readability. Each item in the list should follow the same grammatical structure; in other words, each of the first words would be all verbs or all nouns. If the items are complete sentences, use end punctuation.

Bulleted

Bulleted lists enhance readability and clarity.

Writing for accessibility

When creating content, it is crucial to prioritize accessibility to ensure that individuals with diverse abilities can easily understand it. By adhering to these accessibility guidelines, we can ensure that our content is inclusive for all.

Always provide alt text for images. Pro tip: this also helps with SEO!
Use descriptive hyperlinks that clearly communicate the destination, avoiding generic terms like "here" that lack contextual information regarding the link's destination.
Provide captions or transcripts for all videos.
Check color contrast to ensure legibility.
Include text alternatives for non-text elements, such as infographics or charts.
Avoid ableist language. Be mindful of using language that could unintentionally exclude or marginalize people with disabilities. Avoid terms like "see," "view," "hear," or "walk through" when describing tasks or processes. Instead, use inclusive alternatives such as "understand," "explore," "experience," or "navigate." This ensures that our content is accessible and welcoming to all readers.
