We subscribe to email lists, we get newsletters and email updates from news sources, we have customers and clients (existing and potential) reach out to us this way, and we receive notifications (some we request and others seem to find us).
The important thing to remember is because the email address (or addresses, for those who have more than one) is a very personal way of allowing the outside world to connect with and engage us.
As aging in place professionals (or any other type of businessperson), we must have a reliable way of having people connect with us. We cannot afford to break the circuit. Just like an open switch on an electrical path, a broken water line, or a street that used to be continuous that now doesn't connect through a neighborhood, we cannot allow for people trying to contact us by email to be thwarted. This is not the same as unsubscribing to specific emails or lists or blocking spam. We're talking about not receiving email that we intend to reach us.
We used to rely on our mailing address as the constant in how people could reach us. If we traveled for a few months, went away to school or the service, or otherwise were absent from out regular place of residence for a short period of time, we could always depend on bills, statements, magazine subscriptions, correspondence, and other important information reaching us at that address. If we weren't there, it would be waiting for us when we returned (even with a hold or temporary suspension that we might apply).
The same would be true for parcels or express deliveries that we might request or expect.
There was no need to forward our mail each time we were going to be gone for a few weeks (sometimes longer) at a time. We knew that our regular (aka permanent) address would allow mail, parcels, and other information to reach us. It would either be there upon our return, or we would have someone tell us us what had arrived or even forward specific pieces of mail to a location we were at that time.
When we moved permanently to another address, we would notify the post office that our important (first class) mail should be forwarded to our new address and that the former one should no longer be used. We will notify magazine publishers and others to use our new address, Still, advertising and solicitation mail will still come to that former address for years.
