I've prepared signature for outlook app and everythings works good on web clients like gmail and also in outlook app.
But the problem is when I am testing signature on iOS and Android.

This is code snippet to show my concept.

```html
<!DOCTYPE html>
<html>

<head>
    <meta media="screen" type="text/css">
</head>
<style>
     tr{padding:0px !Important; margin:0px !important;}
</style>

<body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0" style="min-width: 100%; font-family:'Calibri light', sans-serif;">

<table width="350" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td width="139"><span style="font-size: 11pt; display: inline; white-space: nowrap; color: #000; text-align:left;">Test</span><br />
      <br />
      <span style="font-size: 13pt; display: inline; white-space: nowrap; color: #3580C2; text-align:left;">Test2</span><br />
      <span style="font-size: 11pt; display: inline; white-space: nowrap; color: #000; text-align:left;">Test3</span><br /></td>
    <td width="211">&nbsp;</td>
  </tr>
  <tr>

    <td align="left" valign="top"><table cellpadding="0" cellspacing="0" style="margin-left: 10px; border-collapse: collapse;" >
