The other day I got an email reply with a change of someone's address. It made me laugh. It said:
Please email me at my gmail account as I no longer use this account.
Can you guess why I laughed? Of course!
I didn't have the person's gmail address.
I receive such "email me at my other address" replies, without the other address given, several times a year. Are people trying to tell me something? Do they want me not to find them? Or do they want me to work to find them?
Here is my suggestion: If you change email addresses and you want people to be able to reach you, provide your new address–don't just refer to it.
Please write to me here–or at my old address.
