Horizontal lines appearing between blocks

I'm experiencing an erroneous white line that appears in the header and footer element of an email template.


The header element comprises of several block built together to give the appearance of a colour block with an offset rule. The white lines appears at the bottom of the block that contains the rule (see below)



I've seen that this issue has been reported elsewhere and that specifying the email background to be the same colour as the background of the block where the white line appears to be an acceptable work around. However, in this instance the solution is not viable as it would mean changing the whole email background to be the same colour as the header; blue. 

Please can an update be provided as to how your engineers are progressing with getting the issue resolved?

Re: Horizontal lines appearing between blocks

Thanks for reaching out in the Community regarding the issue with horizontal lines in the display of your campaign. We know how important it is for your emails to look consistent across all email platforms. 

One additional potential workaround we have found that you can give a try since the screenshot of your campaign appears to be a single column campaign:


  • Drag a block like a divider next to the affected block to create a column layout
  • Add all the affected blocks to one column
  • Delete the block/divider in the other column, so that the content is back to one column 

I have submitted your request to be contacted/emailed on any updates regarding any changes in the issue as the engineers work toward a solution.
