Diagnose common issues with domains, warming, DNS, and billing.
If Winnr says a DNS record isn't verified, the record either doesn't exist, doesn't match what Winnr expects, or hasn't propagated yet. This walks through diagnosis for each of SPF, DKIM, DMARC, and MX individually.
A domain that stays in Provisioning or DNS pending for more than 30 minutes usually points at a DNS propagation delay, an unresolved verification, or a registrar-side issue. This walks through the diagnosis in order.
Bounces are usually list-quality issues — invalid recipients or full mailboxes. Rejections are provider-side blocks — spam filters, rate limits, or authentication failures. This tells them apart and fixes each.
If the universal inbox isn't showing recent replies, the cause is usually a sync cadence issue, an IMAP auth failure, or replies actually being caught by spam filtering at the recipient side (not delivered at all).
If Smartlead, Instantly, or another sending tool can't connect to a Winnr mailbox, it's almost always credentials (typo, stale password, wrong port) or an IP block. This is the diagnosis.
A sudden drop in warming health score (10+ points in a day) usually means DNS drift, a new blocklist listing, an authentication change at the provider, or aggressive cold sending that outpaced warming. This is the diagnosis order.
If Winnr shows a domain on a blocklist, sending will underperform badly. Priority order — identify which list, understand why, file a delisting request, and clean up whatever caused the listing.
