Dedicated IPs and blocklists

EmailShift checks your domains against domain blocklists, and your dedicated IPs against IP blocklists.

Why only dedicated IPs

If you send through shared IPs of a platform (as most senders do), a listing of one of those IPs is caused by other senders and is not something you can act on. EmailShift therefore only checks IPs that send your mail alone.

Adding a dedicated IP

  1. Go to Domains → Dedicated sending IPs and add the IP.
  2. EmailShift checks that the IP is yours: it must pass DMARC for your domain in your DMARC reports, or its reverse DNS must be under one of your verified domains. Unverified IPs are not checked.

How checks work

  • Each list is checked at most every few hours per IP or domain.
  • A list that stops answering correctly is paused automatically, and its results are shown as "not checked" rather than "clean".
  • A listing on a list that matters opens a case with a link to the list's lookup page. Informational lists are shown but never open cases.
