Did you have a good reason to send a second identical message after 
waiting only 25 minutes for a response from the first?  How about if you 
must do so, say SOMETHING new in the message, and make it a reply to the 
first, so they get threaded together and have the same subject line.

Anyway, your first problem is you never save any data from the first 
file.  You're trying to do two very separate things in the same line.  
You read the data and immediately print it, without putting it any place 
you can reference it.  Try something like:

indata = text_file.read()
print(indata)     #optional

Now, you can do something to indata before writing it to the output 
file.  See how you get along with that.

Another point:  If you get an error, be explicit.  Show us what you 
tried, and quote the exact error (including the traceback of course).  
Otherwise it's like making an anonymous call to the police:

"Hello, somebody burglarized some house yesterday.  Can you please tell 
me what they did with the toaster they broke?"  And then hanging up 
immediately.

BTW, thanks for sending a text message instead of html.
