A mention of your brand from a completely independent organization doesn’t give you the right to use the quote just because it references the name of your business. This is actually a good thing, because having an unbiased, positive review of your brand from a reputable, authoritative source will help build credibility and trust with both new and existing customers. You can’t therefore include the text that mentions your brand in an email, unless you get permission from the owner to do so. However, it’s a good idea to inform your users about the mention with a link to where they can read the content that mentions your business.
