What our clients are saying…
“About Nielsen data: It is once again very positive for us because while the category fell by 11.6% in value, and the cava category decreased by 5.6%, we are once again the green dot in the data, growing vs. the previous year's and increase of market share. These results are clearly related to the MKT campaigns during April and July. So, once again, thank you very much for your wonderful support. We are achieving great things in the UK thanks to these impactful marketing campaigns.”
International Brand Manager Europe & Asia, Codorníu Raventos
“We needed a digital agency that rocks the pants off it in the social & digital space that was fast, flexible, insightful and fun. Critical for us was someone that was responsive, really understood paid digital, and had the ability to make short, sharp, quick creative ads. One Day is that Agency. We are extremely excited to see what 2021 brings working with the talented team as we launch into the UK.”
General Manager, Itchy Baby Co
"Freshers is such a pivotal moment for UNiDAYS. As the UK's leading student platform, working with a tried and trusted team was key. We've found that in One Day. Their professionalism and unique approach to measuring effectiveness and incrementality is truly exceptional".
Mark Hodson, VP of Marketing at UNiDAYS
“It was an incredible experience partnering with 1DA Agency. We handed them a strict budget, and they met it and exceeded our expectations. Their professionalism, creativity, and unwavering support were instrumental in our campaign's success. From designing ads to picking locations and strategies, they were with us every step of the way, and we couldn't be happier with the results."
