Postie tag function usage

Hello guys,

I have an text in html format and sending email to my blog. Postie plugin reads it as plain and everything is fine. It reads the format and posts normal, but I cannot add tags. Adding tags: <tag1> like this in html format is not working. If I choose to read the text in html format, then it works but then my text stays in html format.

What setup should I use for tags?

My text looks like this New games site content

Basically it has some makeup, hyperlinks and so on.

Thank you
