About deleting a Google account that has not been used for more than 2 years

From Friday, December 2023, 12,
If a Google Account is not used for two years, it will be deactivated.
It was officially announced that all accounts (including content and data) will be deleted.

As a result of this, if an invalid Gmail lead is registered, an error will occur when sending the email.This can lead to an increase in unfulfilled leads and an increase in bounce rate.

Please check your email address and delete or exclude from the distribution list any Gmail leads that are invalid or those that resulted in an error when actually being delivered.
