About Me

Nice to meet you!

My names Sinéad Viggars and im the founder of Underdog Marketing. After 15 Years in Marketing working for Small Independent Businesses I decided to take a leap and freelance my service to other small businesses. My experience in Marketing ranges from Fashion retail right through to Construction working mainly with small business with international growth targets. My most recent role of 7 years was the Marketing Manager of Fashion House, Jayley Collection. Which started as a wholesale only brand and is now a retail international leader for outerwear on platforms such as ASOS, Brand Alley and Jayley.com

I’m a very data lead marketeer and although my education is more creative in Photography and Digital Media, most of my success has come from my understanding of Google Analytics and Marketing Data Management. This combined with my photoshop and graphic creation skills pair quite nicely into an all-rounded Marketeer.

I work alongside my apprentice Sausage Dog, Vinny who is currently still on probation for eating post, he’s great company for the team that I miss and works well for biscuits and pats.

Vinny and I like to imagine ourselves as actual members of our clients team. Once we’re onboarded we become your powerhouse Marketing Team that will go above and beyond to support your needs. I particually want to work with small businesses as i know i can make a huge difference that means so much to them; its also more important than ever to help our independent businesses as its them who are the pillars of our economy and communities.

My favourite thing about marketing is watching the numbers increase; i can create a social media ad and then watch the website traffic increase and the sales come in; its a real dopamine kick.

Why I work with Underdogs?

Underdogs have so much potential! and I get a real kick out of making a difference to Small Businesses. Small Business owners are often working incredibly hard with the day to day running of their business, and often have no spare time to put into the Marketing their business deserves. I’m really passionate about working with Small businesses; once i take on a new client you can see me as a dedicated member of your team who will champion your brand and get you the results your business deserves!

Don’t just take my word for it…

During Sinead’s time at St.Dominic’s she was responsible for launching the new school website, social media content, newsletters and arranging all school recruitment events. Sinead not only works well under pressure but is very adaptable; she always met tough deadlines and goals.

Worked with Sinead for close to 5 years and never had any issues! She was an extremely fair manager and never expected us to do anything that she wouldn’t. I learned a lot from her which has helped me move forward in my own career, with nothing but encouragement from Sinead. Would 100% work with her again.

Highly effective strategic partner for multi-channel growth.

I worked directly with Sinéad for 2.5 years on the Jayley brand, collaborating across all digital marketing channels. During this time, we worked together to plan and execute complex projects that required a high level of coordination between SEO, PPC, and content strategy. Sinéad has a strong ability to align creative work with commercial objectives, and our partnership consistently met both financial and business targets. Her approach is methodical, data-driven, and focused on long-term brand growth.

She is a fantastic person to work with, and I can’t recommend her enough for any business looking for strategic online growth.
