problem in bash echo

I am using the echo command to send the output to the file.
I am using the following code:
echo "service started successfully\n" > log

But when I do:
cat log

I get:
service started successfully\n
Instead of a newline after the "successfully"

Why is that and how can I fix it?
# 2  
echo -e "service started successfully\n" > log

printf "test\n" > test.txt
