Dear (person),

First of all I hope this email finds you well and in a good shape, and please accept my apologize for the delayed reply,

However, I am truly sorry to tell you that I no longer be a part of (COMPANY), for reasons that i already mentioned and mainly to look for new challenges and new experiences, experiences that will result a great outcome for me and maybe for (COMPANY) too, as I really appreciate your offer and what you told me about working abroad as it is one of my goals to work and explore other cultures and other working environments.

One last thing is I want to thank you for your acknowledgement of my qualities and competences and for believing in me and for all the support that you and the management team gave me during my time in (COMPANY), really looking forward to the future and what it might bring.
