Katrina Riddle

helps organisations connect with their customers with better digital marketing.

Who is the Shrewd Marketer?

Hi, my name is Katrina Riddle. I have been known to swear too much, talk too fast and I call out bullshit (see there’s that swearing already). I am definitely a perfectionist but I am also one of the hardest working people you’ll ever come across.

I’m a customer marketing expert with a strong focus on email. In fact, I’ve sent out over 10 million emails in my career. Not the kind of email that blasts a whole database, you know those ones that you either don’t open or want to delete before you’ve finished reading the first line? But rather emails that are targeted and personalised to customer preferences and behaviours. And when emails are done like that, well that’s when you see the magic.

I’ve been working in digital marketing for over 15 years, and in that time, I have worked in large companies, small companies, not-for-profits and marketing agencies, and now I want to use what I’ve learned to help you grow your business, build relationships with your customers, and improve your digital marketing.

Some of the companies I have worked with or in include:

Sydney Symphony, Go-Lo, Freedom Furniture, Commonwealth Bank, Cochlear, Lexus, Woolworths and NSW Business Chamber.

I specialise in four areas of digital marketing:

Email marketing

My expertise is using email to connect with your prospects or customers to drive action and grow your revenue.

CRM and customer experience

I combine data and customer expertise to identify opportunities within your CRM to turn it into a gold mine.

Marketing automation

Whether it is developing a funnel strategy or developing trigger based emails across the customer journey, I use marketing automation to boost your organisation’s impact.

Social media marketing

I focus on return on investment not just ‘likes’ on social media. I use my expertise to target the right audiences and get results.
