The Splenda digital marketing campaign aims to increase brand awareness and loyalty through blogger outreach, social media stunts, and media coverage centered around the theme of Splenda being the "Sweetest Serendipity." Key tactics include developing relationships with bloggers who will create content highlighting Splenda, pop-up stands providing Splenda samples to gather social media posts, and SEO optimization. The campaign's success will be evaluated based on increases in sales, social media followers, and the reach of campaign content. The estimated budget is $1.5-2 million.
