What is email deliverability? 

Email deliverability is the ability of an email message to reach the intended recipient’s inbox, so it is also often referred to as ‘inbox placement’. There are a number of factors that affect deliverability including both technical management and infrastructure along with the content and build of the individual emails. 

Who is responsible? 

There are many factors determining good deliverability. Some are simple to achieve by following well-trodden best practices, legal requirements as well as technical specifications. Ultimately the sender is responsible for the success of their campaigns but your choice of ESP (email service provider) will undoubtedly help to increase your chances. Below we identify many of the contributing factors and explain their significance. For clarity and simplicity we have divided these to 3 main areas. While we expect you, our client, to take responsibility for the first and third areas (Contact list quality and content and design), we take the responsibility for the technology and infrastructure but more importantly, we have created many tools and elements of our service to help you achieve the best possible deliverability across the board. Last but not least is our expert advice and consultancy available to you through your account manager.
