Review & fix

Find out why your business email is being rejected.

Invoices landing in spam, replies being rejected or a newsletter failing authentication can be difficult to trace—especially when several systems send email using your domain.

Platforms we work with

  • Microsoft 365
  • Google Workspace

Inetro reviews your sending services and email authentication to identify configuration problems. We help you correct SPF, DKIM and DMARC and work towards stronger protection against domain spoofing.

What we check

  • Which services send email using your domain
  • SPF, DKIM, DMARC and relevant mail-routing records
  • Bounce messages and authentication results from affected messages
  • DMARC reports to identify legitimate and unexpected senders
  • A staged plan for DMARC enforcement and ongoing review

Working with Inetro

We start with your domain, a description of the problem and relevant delivery errors. We identify your legitimate senders before changing authentication records. Where DMARC enforcement is appropriate, we progress in stages and review the results to reduce the risk of blocking valid email.

Questions

Before we start

Can you guarantee inbox delivery?

No. Authentication is one part of delivery. Recipient filtering, sender reputation, content and sending practices also affect the outcome.

Do you support services besides Microsoft 365?

Yes. The review can include Google Workspace, newsletters, invoicing platforms, CRMs and other sending services.

How quickly can we enforce DMARC?

That depends on how many senders you have and whether they authenticate correctly. We confirm legitimate senders before recommending a stricter policy.
