A silent SPF or DKIM change can quietly send your emails to spam for weeks before anyone notices. Drop your email and we'll alert you the moment something looks off, so you fix it in minutes, not after a deliverability cliff.
Check every aspect of your email infrastructure
Mailsoftly handles SPF, DKIM & DMARC automatically. Campaigns, automation, and analytics in one place.
Free to start with your Google Workspace account. No credit card required.
This free email reputation checker scores a domain and its sending IP from 0 to 100 based on the signals mailbox providers actually weigh: whether SPF, DKIM and DMARC are published, blacklist listings across 18 DNSBLs, reverse DNS on the sending IP, and the age of the domain registration. Sender reputation is the main reason authenticated email still lands in spam, so use this check to see your standing before a campaign and after any deliverability incident.
The biggest hits come from spam complaints, sending to stale or purchased lists, missing SPF, DKIM or DMARC records, landing on a DNS blacklist, high bounce rates, and sudden volume spikes from a domain or IP with no history. Recovery starts with fixing authentication, cleaning your list, and warming volume back up gradually. Run the reputation check above to see which of these factors is currently dragging your score down.
