When link previews are used correctly in an SMS message, it is very much like sending an MMS without the additional cost. Remember that there are other factors in rendering a link preview, like the handset settings, so make sure to test on a device to check rendering for Android and iOS. Follow the guidelines listed below to use this feature:
- The link should be added to the end of the text message.
- There should only be one link, if there are two a preview will not show.
- The link preview displays an image and title, but you must configure basic metadata on your website with ogp (Open Graph protocol) fields.
- The link must start with http:// or https://
- For iOS, your Contact Attachment must be saved to the subscriber's Contacts.
Link Preview in iOS:
Link Preview in iOS as a saved contact:
- After load, the preview will render showing a URL, a title, and an image.
- For this to display the subscriber needs to save the Contact Attachment and the short code at the top of the message.
- When the message is reopened, the links at the bottom of the message will show “Tap to load” in iOS.
