Bowker will take over from Alexander Meyer who is moving to eCircle's head office in Germany as group chief financial officer on a permanent basis.
Meyer had previously been joint UK managing director and group CFO.
In his new role Bowker will be responsible for growing eCircle's business in the UK, with a particular focus on developing the offering of the company's technology division, including its email broadcast tool eC-messenger. He will oversee a team of over 60 people.
As operations director, Bowker developed the operations teams in the UK and France, managing over 20 staff across both countries and advising on email strategies for clients including Samsung, Argos, HBOS, MBNA and Standard Life.
Prior to joining eCircle in 2002, Bowker was senior project manager at independent web development agency Hyena where he worked across a number of clients in the public services sector.
Bowker said: "In today's climate, brands are looking to employ accountable marketing that delivers ROI.
"As the largest provider of email services in Europe, eCircle is perfectly positioned to advise brands on how to use email intelligently to do just that, ensuring campaigns deliver results."
Volker Wiewer, CEO of eCircle said: "Since joining eCircle, Simon has shown great ambition and determination.
"We are extremely pleased to welcome him into the role of UK MD, and with his valuable experience and knowledge of leading email campaigns for clients he will undoubtedly drive our offering in the UK market to another level."
