On August 31, 2021, Google notified advertisers it would drop support for expanded text ads for responsive search ads. Google is now reminding advertisers that Ad customizers for text ads, expanded text ads and Dynamic Search Ads will stop serving after May 31, 2024.

As a reminder, Google launched ad customizers a decade ago, in 2014.

The reminder email was posted by Navah Hopkins who posted a screenshot of it on LinkedIn, the email says:

Navah explained in her LinkedIn post that “the only thing that will stop serving are the customizers. Like standard ads, ETAs and DSAs will still run, but with their default text.”

So this is just an ad customizer change, for now.

Here is a screenshot of that email:
