Alignment of text changes in Googlemail!!

betterbargains4u

Whenever I send a message from my Googlemail account, even though I
ensure that the text is centrally aligned, when the message is sent,
some of the text refers to left alignment and also a part of the text
is smaller and not in the bold text that i wrote it in.
For instance the first couple of paragraphs will be centrally aligned
(as meant to be) and the next couple will be left aligned. Part of the
text will also be in a different size font and not in bold.
This makes the message look like a child has written it....and this is
my business account!!!
This only happnes in my Googlemail account, as I have sent the exact
same message in my 3 yahoo accounts and it doesn't change.
Can anyone tell me how to overcome this....please.
