To add to the parent: Most major marketing automation and email marketing tools are going to add these links automatically in the email builder.

Most WYSIWYG email builders built into these tools are pretty painful to begin with, and especially so when content with links is copied from one tool to another. (Think of the poor marketing person being given various blurbs in Word, Gmail, etc. and told to make a functional email out of them while having to use a shitty WYSIWYG.)

Beyond that, most marketers I know have absolutely zero input into what email platform they use. Many organizations are stuck using antiquated, broken tools (I'm looking squarely at you, Eloqua) because of complex existing integrations they have set up.

I don't see this changing any time soon. Few marketing orgs have the IT budget and/or on-staff knowhow to fix this problem. Nor are they likely to be aware of it. Nor, for that matter, are they likely to prioritize it over the many more pressing things they could be fixing that more directly affect revenue.
