People say about my service

★ ★ ★ ★ ★
"Bartosz is an email master! His knowledge of the intricacies of email markup are unparalleled. We worked with him to reimplement an email template while reducing the file size. Other experts were struggling, but Bartosz was able to achieve a 3x filesize reduction without any reduction in functionality or visual appeal. Would recommend Bartosz to anyone who wants the highest quality email templates."

"Bartosz is second to none when it comes to re-coding your mailer templates & newsletters. HTML for email is quite a challenge, it means coding in extreme backward compatibility restrictions as there are so many email clients that will break and distort your communication with your users. Bartosz has this figured out, with literally hundreds of mailer templates he had done before, he has a winning workflow that will outmatch all others in price, quality, and deadlines. Bartosz is extremely professional, on budget, on time, responsive, and on the ball. You will be lucky to have this guy available for your next project. He is worth every cent!!!"
