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 >
Square Balloon are one of those companies that make you wonder how you ever managed before! Their dedication and commitment to your campaigns are second to none, they fully integrate marketing campaigns across all mediums to build a one-stop solution for your business. But it doesn't stop there, once the campaigns have gone they constantly monitor response rates to build a picture of your customers to tailor the next campaigns to better your ROI on every mailing. It goes without saying that their creative solutions are simply stunning and attention to detail is amazing.
Thanks very much for these posters I absolutely love them. The designs you have come up with are really unique and exactly what we wanted, in particular finding a way to include all of the information that we asked for. It was an additional bonus to have the social media cover pages, and was refreshing that you offered this service to us.
