"Relying on what the social site chooses to show for the auto-generated link preview on its side?"   It's not "choosing," tho. The social site is relying on the og:image data/tag it's being fed by Constant Contact. And as was stated much earlier in this thread by an Admin, CC defaults to using the first image in the email as the og:image, with no way for the sender to choose, customize or reassign the og:image. I know CC has a "social share" component for sharing directly from CC but it's clunky, not very useful, and requires linking your social accounts to your CC account.   I think what everyone expects is that CC will at some point add functionality that allows the sender to customize the og:image, header, and text excerpt that will populate when an email link is pasted into a post on Facebook, Twitter, etc. This is something your competitors have offered for years.   Are we ever likely to get that functionality? ...

"Manually add an image to your post, as in actually upload an image alongside making the post. This overwrites the link preview since FB won't have one if other media (such as an actual image) is added alongside the post itself."   Correct, but this also removes the thumbnail and preheader text which is actually a hotlink to the email's webpage version. That's not what I want to do.   "The image that Facebook pulls for the link preview is generally derived from the first image that appears in your email's webpage version - i.e. the first image you have in the email upon sending, starting from the top-left."   And there's no way to change that in Constant Contact in a campaign's settings? ...

Hi William   Facebook doesn't allow you to customize a link image since 2017, unless it's a link from your own website and you've gone through FB's verification process.   For populating the link thumbnail, Facebook can only use what the website (Constant Contact) has designated as the og:image, which on Constant Contact appears to be the first image/header image by default. This can be seen by entering a Sent campaign's Email Link URL into Facebook's Sharing Debugger.   So, I want to specify, in Constant Contact, which image gets used as the thumbnail (og:image) when an Email Link is shared on social media. This is possible to customize on , for example, before a blast is sent. I'm assuming this functionality isn't available on Constant Contact? ... View more
