Short explanations of the checks InboxMonitor runs. Each one says what the result means and what to change. None of them promise inbox placement.

• What the InboxMonitor score is countingThe number starts at 100 and falls by fixed amounts for specific DNS findings. Watch and At risk are labels from that math, not a guess about inbox placement.
• SPF, DKIM, and DMARC in plain EnglishThree DNS records tell mailbox providers who may send for your domain and what to do when a message does not match. Here is what each one checks, without the protocol jargon.
• Moving DMARC from p=none to quarantinep=none collects reports and does not ask receivers to junk failures. Move to quarantine only after the mail you care about aligns, and keep a reporting address on the record.
• When SPF needs too many DNS lookupsSPF fails at large receivers once the record needs more than 10 DNS lookups. The count includes nested includes, not just the names you typed.
• When a sending address is on a blocklistA listing is the list operator's decision. Find which address and which list, stop using that address until you know why, and request removal from that list.
• Cold email in spam: the checks to run firstPlacement depends on more than one DNS record. Start with the checks that prove the domain is allowed to send, signed, and not listed, before you rewrite the copy.
