Run a public check
Enter a domain to check public DNS records and email policies. The report explains findings and next steps; HTTPS and reputation appear separately as additional information.
The Sendequelle platform
Your email infrastructure at a glance
Which domains need attention? Which sending sources are new? Sendequelle brings stored checks, DMARC and TLS reports, and incidents into one overview, helping you understand changes and decide what to do next.
New sign-ins, trial accounts and orders are temporarily closed. The free checking tools are already available without an account.

Inside the product
Your email operations at a glance
The dashboard brings domain status, open incidents and reports together. Filters focus the view; saved views take you back to recurring tasks.
Prioritise domains
Status, coverage and the last check show where to take a closer look.
Understand incidents
Move from a finding to its timeline and technical evidence, with a clear next step.
Review abuse reports
Filter reports by folder, period and status, then review them manually with your team.
Mail server uptime in view
Reachability, confirmed outages and recoveries with uptime history and visible measurement coverage.
Three steps
From a public check to ongoing monitoring
The free check remains fully visible. An account and domain verification unlock history, private reports and alerts.
2
Confirm ownership
Create an account and organisation, then add the provided TXT record to your DNS zone. Sendequelle associates the verified domain with your organisation.
3
Enable monitoring
Set up check intervals, report reception and notifications. Your team can review changes and incidents using the same stored evidence.
Product areas
From the overview to the technical cause
Open a metric to see the affected domains, sending sources or reports. Technical details remain traceable to the stored evidence.
DNS and mail routing
Check where email is routed and whether DNS views agree. Details on MX, DNSSEC, PTR, providers and redundancy remain available.
SPF, DKIM and DMARC
See which senders are authorised, which policies apply and where reports go. Mechanisms, tags and effective defaults are explained.
Mail paths and relays
Trace inbound MX targets and SPF-authorised senders separately to their IP addresses, reverse DNS records and forward-confirmed matches.
Blocklists and reputation
Assess available reputation findings with their source, observation time and limitations. This additional information does not change the email score.
Transport encryption
Review STARTTLS, certificates, DANE/TLSA, MTA-STS and TLS-RPT. Optional mail services are checked without signing in to a mailbox.
DMARC and TLS-RPT
See which sending sources authenticate and where transport failures are reported. Normalised reports link to domains and causes.
Incidents and alerts
Handle confirmed state changes with a timeline, ownership and notifications. Confirmation rules limit alerts caused by isolated outliers.
Teams, roles and API
Give your team appropriate permissions for each organisation. Connect existing workflows through the API, webhooks and exports; changes remain recorded.
Operations and trust
Technical depth without mailbox access
Sendequelle operates outside your email flow. Network checks are limited, raw reports remain private, and different organisations' data stays separate.
Privacy informationLimited network checks
Monitoring does not sign in to mailboxes or send email. Active checks require confirmation that you own the domain.
Private raw data
Raw DMARC and TLS-RPT reports and internal findings do not appear in public results or weekly overviews.
Access control for teams
Organisation permissions, roles, two-factor authentication and reauthentication for sensitive actions protect administration.
Direct contact
Contact the Sendequelle team through the contact form with questions about onboarding, privacy or operations.
Check first. Then keep monitoring.
Start with a technical snapshot without signing up. You can then add your domain to an account for history, private reports and notifications.
