How to Use Grammarly to Keep a Marketing Team On-Brand

The short answer: for a marketing team of six that keeps getting product names wrong, Grammarly Pro is worth $864 a year, 6 x $144 on annual billing per the pricing article (checked on 26 October 2026), once a free pinned list of the terms has not fixed it. Put the team on one Grammarly Pro plan, turn the brand book's naming page into a style rule set, set a brand tone profile, load approved boilerplate as snippets, build one agent that checks drafts against the campaign brief while people write and leaves each suggestion for the writer to accept, then read the rule metrics after a month.

A brand book is a PDF that nobody opens while writing a LinkedIn post at five to six. The product name gets a capital in the wrong place, the tone swings from stiff to chummy, and the review queue becomes a spelling queue. The job here is to move the rules out of the PDF and into the text box. What Grammarly includes and costs is on the Grammarly glossary entry.

What you need first

Four things, cheapest first:

1. The free test. Before paying, write the 20 terms your team gets wrong most often on one page and pin it in the team channel for two weeks. Count the errors in what gets published. If they drop to zero, you have your answer for nothing.
2. The seat arithmetic. For example, a team of six on annual billing is 6 x $144 = $864 a year, per Grammarly's pricing article, checked on 26 October 2026. Seats added later are charged pro rata for the rest of the period.
3. The inputs you already own. The brand book's naming and terminology page, your approved boilerplate (company description, legal lines, product one-liners), and three sentences that sound like the brand on a good day.
4. A baseline. Count the naming and terminology errors in last month's published posts and emails. That number is what the setup has to bring down.

Step 1: Set up Pro and invite the team

Pro is bought on the web and covers up to 149 members. On the Members page, click Invite members, enter the email addresses, and each person joins by clicking the link in the invitation, per the Pro article. You can invite people on Free, Premium or Pro; people on Grammarly Business or Education accounts cannot join a Pro team.

Step 2: Turn the naming page into style rules

Go to the Style Rule Sets page, click Create rule set, name it, assign it to everyone in the organisation, and save, per the style rules article. Each rule has three parts: the original text you want caught, the rule text to replace it, and an explanation your team will see. Leave the replacement empty for words with no substitute, such as jargon you want gone.

The article's own examples map well to marketing: product and company names, terms always in lower case, abbreviations to spell out, jargon to avoid and preferred terms. For more than a handful, click Import list, download the CSV template, fill it and upload it.

Step 3: Keep the rules where they matter

In the rule set's settings you can list the websites where its suggestions appear, for example your CMS, LinkedIn and your email tool. Elsewhere, such as Slack, the suggestions stay hidden unless someone opens the Grammarly widget. External copy gets the rules and internal chat keeps its pace.

Step 4: Set the brand tone

From Home, open the Writing tab and choose Brand tones, then Set up tone profile. You pick the sentences that sound most like your team in a series of scenarios, click Analyze Answers, and Grammarly proposes a tone profile that you edit, marking tones as on-brand or off-brand with an explanation for each, per the brand tones article. Use the three reference sentences from your inputs when choosing.

Step 5: Load the approved boilerplate as snippets

On the Snippets page, create a snippet or import a list from the template, up to 1,000 at a time, per the snippets article. Admins can create snippets for the whole organisation, and in Grammarly for Windows or Mac a backslash typed mid-sentence opens the snippets menu. The company description then appears the same way in every bio, press note and partner page.

Step 6: Add an agent that checks drafts against the brief

This is the agent step, and it runs on Superhuman Go, the assistant from Grammarly's parent company. The agent builder article says the builder is in beta and rolling out gradually to Pro, Business and Enterprise users, so check your account has it.

Create an agent with a short name, a one-sentence description of when it should step in, and instructions covering its role, tone and rules: for example, flag any claim in a draft that is not in this quarter's campaign brief, and any offer that differs from it. Add the trigger Proactive assistance, While writing, so it appears as underlines in email and docs, and set the in-line configuration to manual rather than automatic. Under Tools and Access, give it only what it needs, such as the docs where the brief lives.

The human check: the writer reads each underline and decides. The agent flags; it does not publish. Test it once on an old draft before anyone relies on it.

Step 7: Share it the safe way

The sharing article draws one line that matters. Sharing with specific people lets them run your agent on your connected accounts, and its actions appear under your name. Publishing to the company directory gives each person their own version on their own accounts. For a team agent, publish.

What Grammarly's support pages warn about

• Upload errors on accented characters. The style rules article says an import can fail if the file contains non-English characters, so a Dutch or French term list may need adding by hand.
• One rule set on Pro. Multiple sets need a Business plan, which allows up to 50.
• Not on the keyboard. Style rule suggestions do not appear in the Grammarly Keyboard on phones.
• The Office add-in is going. Grammarly is retiring it and points teams to Grammarly for Windows.

The homepage leads with customer results. A vendor picks the customers it quotes, so the only result that counts for this decision is your own error count against your own baseline.

How to know it worked

After 30 days, open each rule in the set: the page shows how often it was viewed, accepted and dismissed. Rules with many dismissals are wrong or badly explained; fix the explanation first. Then recount the naming errors in the month's published content against your baseline. If the count fell and the reviewers spent their time on arguments rather than spelling, the setup earned its seats. Grammarly's revenue is the member count, charged pro rata from the day each person is added, so a seat whose holder never publishes pays the vendor and does nothing for the brand.

If the real gap is that nobody owns the brand voice, rules will not close it: that is a seat rather than a setting, the one an interim CMO fills.

FAQ

Can each of our brands have its own rule set on Pro?

No. Pro allows one style rule set, and Business plans allow up to 50, per the style rules article.

Does the team see suggestions in Dutch copy?

In beta, yes for spelling, punctuation and grammar, plus clarity suggestions, per the multilingual article.

Do agents remember what we write?

Not between sessions. The agents page says agents do not retain information across sessions or agents, except a voice profile you choose to create from a writing sample.
