Many influencers, like YouTuber Margot Lee who has 440,000 subscribers, are brand ambassadors for major retailers.

Although Margot (she prefers to keep her last name private) initially started her channel as a hobby, sharing fashion and beauty tips in high school, she has carved out a brand niche for herself as a college YouTuber. She has worked with brands like Amazon, Victoria’s Secret, and Sephora through brand sponsorships. And recently, she was a part of Sephora’s 2019 brand ambassador program.

A brand ambassador program is often similar to a long-term brand campaign, but there are some differences. Brand ambassador programs are often more formalized and for some companies, like Sephora, the brand ambassadors are a part of a small group of creators provided with added resources and access to the brand (like trips or events).

There are a variety of different ambassador programs and they offer different terms. Some brand ambassadors earn commission for driving sign-ups or through referral codes, while others are paid a set rate for promoting certain products from the brand on platforms like YouTube or Instagram. Several ambassador programs simply provide free gifts or exclusive event access.

As an ambassador for Sephora, Margot was sent on trips with the company, and promoted makeup and beauty products by the brand on YouTube and Instagram.

Ambassador programs are a way for brands like Sephora to share branded content and product news with an influencer's audience. Influencers become a spokesperson for a brand, repping clothing, makeup, collaborations, discounts, store credit cards, and anything a brand may want to push.

Some fashion brands like Outdoor Voices, Fashion Nova, or Ivory Ella have a widespread network of influencers who serve as ambassadors across Instagram, YouTube, and TikTok. If you've seen the #NovaBabe hashtag, you've likely seen an ambassador program post for Fashion Nova.
