Accidentally unsubscibed email

My domain is:
I ran this command: unsubscribe
It produced this output: I am sorry to see you go
On a regularly base I get a notification that the certificate for “” will expire.
This domain however does not belong to me.
As this email is not meant for me, I unsubscribed the email under the assumption that this would solve this issue.
How can I subscribe again? Can I subscribe by renewal my certificate or do I have to take other actions?

Can you paste some of the email? What address was it from? Was it from Let’s Encrypt or from your hosting company?

Unfortunately, the only way to resubscribe to Let’s Encrypt’s emails is to change the email address on your ACME account(s), which you can do via your ACME client(s).

Both of those domains are hosted on the same IP address. Are you using shared hosting? What software is being used to manage the certificates? A control panel?

If I remember correctly, there have been some cases where a misconfigured or buggy control panel used by multiple customers will direct all certificate emails to one customer. If that’s going on, you need to talk to your hosting company or control panel developer.

Thanks for you quick reply to this novice. The email is the usual notification email from Let’s Encript. It only refers to the wrong domain.

Your certificate (or certificates) for the names listed below will expire in 10 days (on 23 Apr 20 02:23 +0000). Please make sure to renew your certificate before then, or visitors to your website will encounter errors.
We recommend renewing certificates automatically when they have a third of their
total lifetime left. For Let’s Encrypt’s current 90-day certificates, that means
renewing 30 days before expiration. See for details.

For details about when we send these emails, please visit In particular, note that this reminder email is still sent if you’ve obtained a slightly different certificate by adding or removing names. If you’ve replaced this certificate with a newer one that covers more or fewer names than the list above, you may be able to ignore this message.

ACME account(s)” does not ring a bell for me. I maintain my own website but have little experience. I have a free certificate via my provider (
What software is being used to manage the certificates? A control panel?” Yes, via the control panel of my provider. I will contact my provider to see if they can give me some advice.
In fact it seems not a big problem but now I have to be aware to renew my certificate every 12 weeks without notification.

Can it be a solution to remove my certificate via the control panel and request a new one? Or does this give problems with my website?

According to my provider I could remove my certificate and install it again. So I did.
Thanks for the support.
