How can I add a discount tag in the subject line?

Hi ​@Dipesh 

What you’re seeing is an annotation (possibly in Gmail?) . It is possible to add this following the guidelines here: https://help.klaviyo.com/hc/en-us/articles/23145809959707 though inbox providers may not always show the annotation.

This works (see below in Gmail web) by adding this, for example, to a text block in the footer:

<div itemscope itemtype="http://schema.org/DiscountOffer">
    <meta itemprop="description" content="30% Off Black Friday"/>
    <meta itemprop="discountCode" content="BF30"/>
    <meta itemprop="availabilityStarts" content="2024-11-25"/>
    <meta itemprop="availabilityEnds" content="2024-11-27"/>
  </div>

I think the help page above may be out of date regarding having to request Google to add you to an allowlist. I haven’t!

Note: Klaviyo states that this can only be used in a custom/hybrid HTML but my example uses the drag and drop editor to add that scheme to a text box. If you can reach out to Klaviyo to confirm it’s OK to use this way, I would. I would also test over a range of email clients. 

Hope that thelps
