Help Can stock email app be reinstalled on Galaxy S5?

[Android Question]

I like the stock email app on my Galaxy S5 SM-G900A (AT&T); but when I mail a hyperlink, it arrives as plain text on any computer except my mobile device: if I mail the link to myself if arrives functional on my phone but as plain text on my PC.

Installing AquaMail allows me to send links, but this app offers everything but colored font that is useful when replying to mail. I tried the resident Gmail mail app on my device and it too sends links correctly.

So I'm thinking the stock email client got corrupted. Samsung's Smart Switch does not permit update or download of the stock email software. I see sites offering a download of the particular app but also requiring access to my contacts list. Apart from a factory reset, any suggestions?

Here are the S5 stock apps. There's the app for email there too.

Thank you soooooo much. If I may impose on you a little further, how do install the app? I extracted the contents and then copied them to the Downloads folder on my Galaxy S5. I see two APK files: "secEmail_K.apk" and "SecExchange.apk." Do I run both files, or is there some other procedure?
