This information is for the rest of our readers; it was sent to Molly via the ticket and is reproduced here for any one else who has this issue reported.
We didn't find anything incorrect in our handling of links, and tests with Safari on a Mac and on an iPhone didn't produce this error using the message from Molly's account. We feel the issue is on the recipient's end with one or both of the issues mentioned in this Apple Support article:
Safari: "Could not open the page, too many redirects"
This might happen if you visit a page that's been set to open another page, but the next page is instructed to go back to the original page.
This issue can be caused by the website you're trying to view. Safari might be able to open the website at a later time, when the website's redirect problem has been corrected.
This issue can also happen if redirect information has been cached after it's no longer needed. In some cases, removing related cookies and cache in Safari can resolve repeated redirects:
- Safari, choose Safari > Preferences.
- Click the Privacy icon to view Privacy settings.
- Click the Details button that appears under the Remove All Website Data button.
- Search for the name of the website that you are trying to view.
- Click the Remove button.
- Close the Safari Preferences window.
If the issue continues, repeat the steps without searching for a specific website. Click the Remove All Website Data button to remove all of your cookies and cache files. If this does not resolve the issue, contact the owner of the website you're trying to view for additional help.

For iPhones, this article may shed some light on the issue:
Solve a problem visiting websites in Safari for iOS where a message appears that says “Could not open the page, too many redirects.”
- From the Home screen, open “Settings“.
- Scroll down and select “Safari“.
- Scroll to the bottom and select “Advanced“.
- Choose “Website Data“.
- Scroll to the bottom and select “Remove All Website Data” or select “Show All Sites” > “Edit” and remove the site you are experiencing problems with.
Now when you attempt to use Safari on your iPhone or iPad again, you should no longer experience this error message.
