What changes
What is going wrong
- Deliverability breaks quietly. Nothing fails loudly; the numbers just soften over weeks.
- By the time it is obvious, the reputation damage is done. It takes longer to undo than to cause.
- Most guidance on this is written for engineers. You should not have to learn what a pointer record is.
What you have at the end
- Authentication checked, with the exact record to add where one is missing
- Your domain and address checked against the lists that matter
- The list hygiene problem behind it, named
- A report in plain language you can forward without explaining
What I do about it
I check your authentication. When a record is missing, I tell you exactly which one to add.
I check your domain and sending address against the lists that matter.
I look at what your list health does to your reputation. That is usually the real cause.
I write it up so you can forward it to whoever runs your sending.
