By mailbox provider
Gmail Sender Requirements
Meet Google’s bulk-sender rules — SPF, DKIM, aligned DMARC, one-click unsubscribe, and a low spam rate — and confirm your real senders pass before Gmail rejects them.
Microsoft Sender Requirements (550 5.7.515)
Understand and fix the 550 5.7.515 rejection: get SPF, DKIM, and aligned DMARC in place for Outlook.com and Hotmail high-volume senders.
Yahoo Sender Requirements
Satisfy Yahoo’s bulk-sender requirements — authenticated mail, aligned DMARC, and one-click unsubscribe — and keep out of the spam folder.
