Nobody is truly perfect and this time, Google Adsense did a goofup.
They have sent an email titled “Google AdSense: Check your recent payment” to their Adsense Publishers containing the information about the recent payment they have made to the publishers.
Following is the content:
Check your recent payment
We sent a payment for your Google AdSense earnings on 21 Jul 2016.If you haven’t received your payment within 5 business days from the date of this email, please contact your bank for more details.
The email was received on August 7 2018. Possibly this is a false alarm and many of the publishers received the email.
Here is the screenshot.
Did you receive the email as well?
