How do I check if my sending domain or IP is blocklisted?

Look up your sending domain and IP on public blocklist checkers and in Google Postmaster Tools, then confirm with bounce messages that name a block. Fix the cause before requesting removal.

Not every listing blocks mail equally, and some are minor. Bounce text usually says which list is responsible.

Find out why you were listed, such as spam trap hits or complaints, fix the practice and then follow the list removal process.

In practice.

A store sees a spike in bounces mentioning a blocklist. It confirms the listing through a lookup, cleans its list and removes risky segments before asking for delisting.
