Supporting London based businesses with their Web & Digital success


I have found Square Balloon on the MailChimp Experts Directory while I was looking for someone to design an email template and am very happy with the service and product I received.

Eoin Oliver was very professional and thorough in his work, as well as honest which is a quality you do not find often these days. He asked for our feedback several times to make sure we were happy and responded promptly to any question we had or amendment we asked him to make.

I would definitely recommend this company and use them again in the future.  See verified independant testimonial >


I have worked with Square Balloon multiple times. I have found them very responsive and committed to excellence. They will ensure the work is done to the best of their ability. They are very thorough in testing and quality assurance. I would highly recommend Square Balloon to anyone that needs a MailChimp expert.  See verified independant testimonial >


We found Square Balloon via the MailChimp Experts Directory, and were very satisfied with the process from quote to delivery. Eoin was able to create a highly user-friendly and modular template based on our company's brand identity within a very short amount of time, and provided fixes and updates based on our initial feedback and experience. I would not hesitate to use Square Balloon again and would highly recommend them. See verified independant testimonial >



We approached Square Balloon to design our website and were very impressed with the way that they involved us in the design process from the beginning. We had a clear vision of what we wanted to achieve; they were able to offer guidance and advice so that we could achieve the desired result.

We are delighted with the creation that they delivered and we are proud to say that people regularly comment on how professional and aesthetically appealing our site is. We regularly get CVs uploaded via the site, which demonstrates its value and that it works! Thanks for a great job.
