There's only ~25 of us and we used to get together for an extended family dinner once or twice a year - and I would just casually tell others that if they want their [email protected] email just ask me.
No one ever did.
Also I tried the portal thing - I put a simple webpage at https://lastname.com/ where it basically said to ask me for email accounts or web space... again, no one ever asked, not once. Not even my mother, she's been using the same Hotmail/Outlook/O365/whateveritsthisweek account since late 90s and doesn't want to move anywhere.
