Jessica Principe All Girl Shave Club

I loved working with jessica

I absolutely LOVED working with Jessica!  Her knowledge and skill extends far beyond email marketing and the Klaviyo platform, even though she's a master at both of those things too! I hired her to help me set up several email flows in Klaviyo. With her guidance and direction, those email flows have continued to bring in revenue day after day.  My revenue from email went from 4% to consistently between 22-25% of revenue every month.  All along the way, she taught me how to read and understand the data so I can use it to make decisions in my strategy moving forward.  

I was new to Klaviyo and it can definitely be intimidating to learn a new platform, but Jessica patiently taught me how to use Klaviyo with clear, easy to follow directions.

She gave me the confidence to run a strong email program as well as confidence to do things in my Shopify and google analytics accounts that I never would have known how to do! She is a true partner for her clients in all things e-commerce and I highly recommend her to anyone who is looking for support and help in growing their e-commerce business!

Jessica is my savior

OMG Jessica is my savior. I had just switched over to Klaviyo from Active Campaign. It was a big job so I hired someone else to help me with the process. I wish I had found Jessica first!

It took months to get the switch done, and several “It’s done!” emails only to find when I tested it out, that there were several problems. Back to several more months of waiting for it to be fixed and more ‘It’s done!” emails. I finally got smart and asked for referrals for someone else to help me just complete the job – fix the broken bits on my site and polish it up so I could finally move over to Klaviyo. Jessica did it in a heartbeat! AND, she showed me why things weren’t working as they should have and what the fix was, thus I learned a lot in the process. I plan on hiring Jessica as my Klavio expert!

What She Teaches Works!

I did a strategy call with Jessica and even though it was only an hour it was packed with value. She gave it to me straight without any fluff and focused on my business and where I was at. I had great engagement on social but it wasn’t converting to sales. Jessica pushed me out of my comfort zone to sell live on social and it worked! Getting that first live sale really gave me the confidence to keep going, and every time I get on live, I make more sales! I love learning from Jessica because she’s been where I am and she really does know her stuff. What she teaches works!

Jessica is a Rockstar

Jessica is the ultimate ROCKSTAR when it comes to eCommerce and Email Marketing. Her CAN DO attitude is amazing to work with. 

I know that she has all our email marketing needs covered and I never have to follow up or second guess what she is doing. Her creative ideas and how to increase conversions have been super helpful in our small but growing brand. I highly recommend her for all your business/eCommerce needs!! Don’t hesitate, she’s worth it!

She Brought Me Back to Reality

I have been working with Jessica for over 4 months now with my Subscription Box Business and she has been AMAZING! She gave me REAL and VERY SPECIFIC tactics that I can focus on to help my business grow. So many businesswomen are right-brained and creative but lack in the implementation process or get lost in the “concept and dream”. That was me! Jessica has been great in bringing me back down to reality and tackling my business plan step-by-step.
