Web traffic works while mail fails
The domain reaches your website, but incoming messages no longer arrive at the right provider. A working page hides the mail-routing records that were left out or changed in the domain update.

Keep email working when domain settings change
A domain change keeps your website up but breaks business email. Some visitors may still see old content from a separate cache. We find the affected DNS and content layers, restore approved records, then test mail and the corrected page.
Discuss this problemHow We Help
We compare your authoritative DNS records, the official ones for your domain, with the setup your mail provider approved. We also check what affected resolvers, the services that look up DNS answers, return. A working website does not prove that mail routing or sender records survived the change. We investigate old page content separately, checking it against what your origin server sends and what browsers or the edge cache show. Each fix targets the cause we can show: the authoritative DNS, an outdated origin deployment or the relevant cache settings. Where appropriate, we clear the cache through a supported method. We then test messages and check that the intended current content is really being served.
Signs This Is the Problem
Sender checks stop matching
An approved sender stops passing its expected checks after authentication records change. Ordinary mailbox email may look healthy while CRM or marketing messages reveal the missing setup for that sending route.
Different networks see different results
Different people see different DNS answers or website versions after the change. Mixed resolver and cache behavior makes it hard to tell whether the authoritative setup or the served content is still wrong.
What We Investigate
Compare old and current DNS records
We check authoritative mail-routing and sender records against the setup your provider approved. Earlier records help us find entries lost during a website-focused change, so we aren't guessing at new records from symptoms alone.
Review delegation and resolver evidence
We confirm which nameservers your domain points to, known as delegation, and compare the answers affected resolvers give. We separate delegation faults from older answers still being held, so a correct record isn't mistaken for a change that has already reached everyone.
Separate website caching from DNS
We compare old pages with your origin server and the browser or edge responses we can see. That separates an outdated deployment from cached content, since either can linger even after the mail DNS is fixed.
What We Repair
Restore approved mail records
We restore approved mail records at the authoritative layer and keep the other services you need. Controlled send and receive tests then show that the affected mail routes work with the intended provider.
Validate delegation and record coexistence
We fix confirmed delegation faults and records that clash. The domain setup keeps your website, mailbox and authorized senders, and we don't replace them with a website-only set of records.
Repair the demonstrated stale-content layer
Within scope, we correct outdated origin content or the cache layer we showed was at fault. After a supported cache clear or settings repair, we check that affected pages serve the intended current version under the tested conditions.
How We Verify the Fix
- Authoritative DNS publishes the approved mail routing records for the active mailbox provider.
- Reviewed sender authentication records stay consistent with the approved sending services.
- A controlled inbound message reaches its intended mailbox after the routing fix.
- After the in-scope origin or cache fix, affected pages serve the intended current version under the tested conditions.
Questions About This Work
Why can the website work when email fails?
Web and mail services use different domain records. A website change can keep the page address working while losing mail routing or sender authentication. We compare the authoritative records each affected service needs, and we don't use a working website as a check on email health.
Does the correction take effect everywhere immediately?
Not necessarily. Cached answers and content can linger under their existing settings. We confirm the authoritative fix and the intended origin version first, then compare the affected paths. Our test results state what was tested, and we don't promise that every outside resolver or browser updates right away.
What records should we provide?
The domain and the affected service names help, along with a redacted failure message or a public page showing old content. If you have them, include the change time and the earlier records. We don't need passwords or secret connection values for the first DNS and content review.
Tell Us What Is Happening
Name your domain, mail and hosting providers. Share one redacted failed message, or a public page showing old content after the DNS change, so we can identify which service layer needs fixing.
