What services are there to check emails for passing Spamassassin?

Question

Fight against spam

Many letters need to be sent to corporate emails, tell me how to check the letter on the inbox as fully as possible
. There is no access to Spamassassin and its logs.
Tell me, are there any sites like www.mail-tester.com
to check the letter for passing the filter, I am especially interested in assigning points to the letter (what for).
