Save mail message activity, saves the documents but the content saved inside is HTML

I am trying to save the mail message using .txt file. It is saved but the content inside the file is html coding and other unwanted things. The body of the mail content is not saved. Please help me in this.

What does the body of message contains , do you want to extract the whole data from body of mail or specific data.

I want to save the whole data from the email body. It will be mostly in text format.

Is the body of mail same at all times or it changes in every mail.

It changes every mail.

Is something common like addressing in mail i.e Hi ‘any name’ and ending mail like ‘Thanks & Regards’ then we can use string function to find the index after Hi and substring function to find data of the body.
