Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
Yes, you received a number of certs with different lists of domain names recently. The emails should list the domain name(s) on the cert that it is warning about.
As the email notes, each different set of names on a cert is considered unique for this purpose.
There are two emails per such unique cert. The second and last is 7 days before expiry. So, you won't receive many more. As also noted here: Expiration Emails - Let's Encrypt
View the list of the domain names in each cert using a tool like https://crt.sh. Click the crt ID on its list and look for the Subject Alternative Names section. These are the names you requested for that cert. Below is just the common name you need to view it yourself to get the SANs list.
