Email template appearing with a white line between image blocks

Hi  @fern1!

I share with you recommendations that you can check if they are feasible. 

1. Check for Extra Spacing or Padding: Be sure there is no extra padding, margin, or border applied to the images in the HTML code.

<img src="https://example.com/image.jpg" style="border: 0; display: block;" />

1. Use Inline Styles: Use inline CSS to set the image display properties. This can help ensure consistency across different email clients

<img src="https://example.com/image.jpg" style="display: block; border: 0; margin: 0; padding: 0;" />

1. Table Layout: Wrap your images in table cells to ensure there are no gaps caused by different rendering engines.

<table cellspacing="0" cellpadding="0" border="0">

  <tr>

    <td style="padding: 0; border: 0; margin: 0;">

      <img src="https://example.com/image.jpg" style="display: block; border: 0;" />

    </td>

  </tr>

</table>

1. VML for Outlook: For better rendering in Outlook, you might consider using (Vector Markup Language) for your images

<!--[if gte mso 9]>

<v:image xmlns:v="urn:schemas-microsoft-com:vml" src="https://example.com/image.jpg" style="width:600px;height:200px;border:0;display:block;" />

<![endif]-->

<img src="https://example.com/image.jpg" style="display:block; border:0; outline:none; text-decoration:none; width:600px; height:auto;"/>

1. Reset CSS: Include a CSS reset for images at the top of your email’s inline CSS

<style type="text/css">

  img { display: block; border: 0; margin: 0; padding: 0; }

</style>

Test it on tool like Litmus or Email on Acid once changed to preview how your email renders across different platforms and devices.

¡Hope this helps!
