Removed from a mailing list

[Nefeyove]

I have received an email notification from Lets Encrypt, by mistake I’ve removed myself from a mailing list. What do I have to do to be re-instated?
Please help?

Hi,

Please take a look in Expiration Emails - Let's Encrypt

Especially the below section:

Note that your unsubscribe is only valid for one year, so you will have to renew it every year.
There’s not yet a way for us to efficiently re-subscribe you if you unsubscribe. Our email provider, Mandrill, has a manual mechanism that we still need to automate.
However, you can change the email address on your account, which effectively re-subscribes you. Many common email services treat yourname+1@example.com the same as yourname@example.com . So if you update your email address to yourname+1@example.com , you can start getting expiry mail again. With Certbot, use:
certbot update_account --email yourname+1@example.com

Thank you
