Tags Errors on Sended E-Mails

Hello All,

I use yattag to generate reports of our services and I send the HTML output via e-mail to people. I have an issue with generating HTML output. In the code, as you can see, every tag proper with syntax and structure. But on EMails, we have problems.

E-Mail Outputs:

Tags have extra space or generate extra tag

Output of Issue: <td>N/A< /td></td>

Output of Issue:

<tr>
<td>StartDate</td>

<td>779 Days Past</td>
</tr>

                counter += 1
    return doc.getvalue(), self.status_list

So, I really don't understand why I get these issues. And the main problem is this not be every time. Different days, different machines make these issues.

May somebody has any idea about this issue?

Thanks & Regards, KK
