I have three email links in my website, and want each of them, when clicked, to open in a new tab. However, I can’t find any way to set it so that a new tab opens.
The browser controls how mailto links are handled.
If you really wanted to, you could;
Change your “open email in a new tab” link to a standard link
Make it e.g. /email?email=foo@bar.com with a target of _blank ( open in new tab )
Create an /email page in Webflow
Add custom script to pull the email querystring param
Immediately do a redirect to mailto:<whatever email>
Display a nice message
That message is important because depending on the browser configuration, some people will see a new tab created and then their mail reader will open. Others will see the new tab created and then replaced with an online email program like GMail.
