Hello,

When I apply the HTML source to HubSpot email, some of its code seems to be automatically changed.

I just added the style source, border=“0”.  
But it was automatically edited to border-width: 0px; border-style: solid; in HubSpot Email.

Is there any guideline do I have to follow?

Best,  
Eunjin

Hi @jini

Thank you for reaching out.

I could not find something similar in the Community, and I see that you have opened a ticket with the technical support team as you have access to it - they will be better able to help and see if something is wrong here!

Thank you

Best
