Account email update and TLD rate limits?

Help
1

My domain is:

I ran this command:
certbot update_account -m email+3@example.com

Why I'm adding an index to the e-mail -I'm not getting expired emails ( there was third-party issue ( AWS), and someone may have accidentally unsubscribed

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
.... omitted for brevity.....
IMPORTANT NOTES:

I use Aws Route 53 certbot hook and using a cron script to check the certificate and renew it if required via certbot

The version of my client is certbot --version
certbot 0.31.0

Though it reports that e-mail change is successfull, the certbot does not update:
/etc/letsencrypt/cli.ini email = email@example.com

I can update cli.ini myself? Is this because of my client version? Is it supposed to do it, or does it's just doing it on the letsencrypt side via APIs?

I have a bunch of other hosts and domains that use the same certbot agent account.

By changing the account e-mail do I risk hitting Duplicate Certificate or other limits in normal circumstances, at any point?

Cheers,
Martin

cli.ini is not managed by Certbot, but by the user. I think the email setting in cli.ini is only used when registering a new account, so if you're fine with using the -m option or running Certbot non-interactively when registering a new account, there's no need to set it in cli.ini.

The email address is not related to any rate limit at all.
