On Monday, July 15th, Yahoo Mail will be removing all inactive email accounts (specifically, those that haven’t been logged into for the past year) and will be releasing them back into the public domain.
This could potentially affect anyone who currently has a mailing list that includes these unresponsive Yahoo email addresses, because if someone else picks up the released email address and gets an unfamiliar email or newsletter, they may end up marking it as spam.
If you have a mailing list that may include some of these email addresses, you may want to identify and remove them as soon as possible. If someone re-registers one of the released emails, gets your newsletter by mistake, and marks it as spam, it can easily cause ISPs like Google and Gmail to block any further emails you attempt to send.
It’s never pleasant to have to delete subscribers, but it’s better than being marked as spam.
Remember, Yahoo is making this change on Monday, July 15th, so try and contact your Yahoo contacts ASAP.
