I'm having a consistent problem with emails sent via Marketing Cloud. We use the classic content builder and HTML paste for newsletters. We have a problem where some links get extended to include the space or punctuation immediately after them or extra spaces are added, even though those characters are outside the closing tag.
...swiftest <a style="color: #035781;" href="https://www.example.org/">refugee outflow</a> after...
shows up in my inbox as
...swiftest <a style="color: #035781;" href="https://www.example.org/">refugee outflow </a>after...
And I can't figure out why. The same thing sometimes happens with commas and periods, where a space is added between the end of the text and the comma (which is outside the link). It doesn't happen on all links, just a handful, but it consistently happens across all the emails we send. These links show up correctly in the preview within marketing cloud, but appear incorrectly in email clients from both test and real sends.
I was told by my predecessor that this is a known Marketing Cloud bug and we can't do anything about it, but I can't find anything about that online. Has anyone encountered this or know what I'm doing wrong?
It appears that removing inline styles from the A tag fixes the issue. Without the style above it shows up correctly, but with the link extends into the extra space. However I still don't know why this is happening.
