Trouble sharing an eSIM promo code via email

[Lawrn]

Hey everyone,

I'm trying to send an eSIM promo code to a colleague using Roundcube, but the link always ends up unreadable or the formatting gets messed up. I've tried plain text and HTML, but it still fails.
Has anyone managed to handle external links in emails without Roundcube altering them? I really need the code to stay clickable and clear.
