Any link on your Insta website can be made into an 'Email' link. When a visitor taps this link their Mail app will open, allowing them to write a message to you.
Here's how to create an 'Email' link:
1. Add a new Card to your Insta site, or edit an existing Card
2. Tap the pencil symbol to edit an existing link or tap + to add a brand new link
3. Add a link title. In this example, that's 'Email me'. Then, in the URL field type type 'mailto:' followed by your email address.
For example: mailto:[email protected]
(Note that there is no space between mailto: and the email address!)
4. Tap Done. Then Preview and Publish to update your Insta website with your changes.
A visitor on your Insta website can tap this email link to write an email to you:
