Which tool do I need?
If messages land in spam, start with the domain: missing or broken SPF, DKIM and DMARC records are the most common cause, and the deliverability checker shows them in seconds. If authentication is in order, look at the message with the spam word checker. And if you are seeing bounces, check addresses with the email address checker before you send again.
