As outlined in this blog post by Ben Nadel, Yahoo mail doesn't render anchor tags with encoded HREF attributes.
When I try to send links to cards over Butler with
[{cardname}]({cardlink})the raw email link looks like this:
<a href=3D"https://trello.com/c/hf=
Sy4j1P">TEST CARD</a>
Links render fine in Gmail, and if I forward the mail from my Gmail account manually to my yahoo, the raw message looks like this instead:
<a href=3D"https://trello.com/c/hfSy4j1P" target=3D"_blank">TEST CAR=
D</a>
It is the same with the "Click here to unsubscribe", but links in emails directly from do-not-reply@trello.com aren't encoded like this.
Is there any way to alleviate this issue?
