WHAT OUR CLIENTS SAY
The team at Milk Bottle Labs do a fabulous job. Projects always run smoothly and to schedule, with minimal intervention from our side.
Oonagh O'Hagan
Owner, Meaghers Pharmacy Group
In 2025, we tasked Milk Bottle Labs to migrate OneSonic from WordPress to Shopify. It was possibly the best business decision we made in 2025. A stress-free migration. It is a wonderful team.
David Cawley
Owner, OneSonic
The guys at Milk Bottle really over-delivered. The service and quality of work was impeccable, and I only wish all the companies I engage with were as enjoyable to work with as the team at Milk Bottle.

QUESTIONS
Frequently asked.
How much of my revenue should come from email?
Healthy Shopify brands earn 20–40% of total online revenue from Klaviyo (email + SMS combined). If you're below 15%, there's usually significant upside in flows alone.
Do you work in Klaviyo only or other ESPs?
We specialise in Klaviyo for Shopify because the integration is best-in-class. For brands on Mailchimp, Omnisend or dotdigital, we typically migrate to Klaviyo as part of onboarding.
Can you write the copy and design the emails?
Yes. Most retainer clients have us handle copy, design and production end-to-end. If you have an in-house designer, we can hand over branded templates instead.
How long until I see results?
Foundation flows (welcome, abandoned cart, post-purchase) typically lift Klaviyo-attributed revenue within 30 days. Compounding gains continue over the first 6 months as we add flows and run campaigns.
Is SMS worth doing alongside email?
For most Irish and UK Shopify brands, yes, on a small subset of high-intent flows (abandoned cart, back-in-stock, VIP). We help you stay on the right side of GDPR and don't recommend SMS for everyone.
