Why Are Your Business Emails Going to Spam?
Your emails look fine. Your clients never receive them. This is one of the most common — and most fixable — IT problems DM1 finds when taking over from a previous provider.
Book a Free Email Health CheckIt's Almost Never Your Content — It's Your Configuration
Spam filters don't just look at what you write — they check your domain's technical records to decide whether to trust your emails at all. Three settings called SPF, DKIM and DMARC tell receiving email servers whether your domain is legitimate. If they're missing or misconfigured, your emails go straight to junk. DM1 finds and fixes these issues as part of every new client onboarding.
Most Perth SMBs DM1 takes over have at least one of these three settings missing or incorrectly configured — even businesses that have been operating for years.
What DM1 Covers in an Email Health Check
We audit your domain's DNS records and email authentication settings against current best practice. Here's what we look at:
SPF — Sender Policy Framework
A DNS record that lists which servers are allowed to send email on behalf of your domain. Without it, anyone can send email pretending to be you — and spam filters know it.
DKIM — DomainKeys Identified Mail
A digital signature attached to every outgoing email that proves it hasn't been tampered with in transit. Missing DKIM is a major spam trigger for Microsoft and Google filters.
DMARC — Domain-based Message Authentication
The policy that tells receiving servers what to do when SPF or DKIM checks fail. Without DMARC, there's no enforcement — and no visibility into who's sending from your domain.
MX Records
Your mail exchange records must point to the correct server. Incorrect MX records cause delivery failures and are a common mistake after a domain or hosting migration.
Sender Reputation
Your domain builds a reputation with email providers over time. DM1 checks whether your domain or IP has been listed on any spam blacklists.
Microsoft 365 Connector Settings
For businesses on M365, the outbound connector must be correctly configured. DM1 verifies this as part of every M365 health check.
Problems Perth Businesses Bring to DM1
These are the email delivery complaints we hear most often when a new client comes on board:
'My client said they never received my quote.'
Nine times out of ten this is an email authentication problem. Your email arrived — in their spam folder. They never saw it.
'My invoices keep going to junk.'
Invoices often trigger spam filters because of dollar amounts and payment links. Proper DKIM signing and DMARC policy dramatically reduces this.
'We switched to a new domain and now no-one gets our emails.'
A new domain starts with zero reputation and no authentication records. It needs SPF, DKIM, DMARC and a warm-up period — most IT providers skip this entirely.
'Our marketing emails are being blocked.'
Bulk email requires additional setup including a dedicated sending domain and authentication records aligned to your marketing platform. DM1 handles the configuration end-to-end.
'Someone is sending scam emails pretending to be us.'
Without DMARC enforcement, your domain can be spoofed. DM1 sets DMARC to quarantine or reject mode to stop this and alerts you when it happens.
'Our previous IT provider said it was fine.'
It often isn't. DM1 uses independent tools to verify your actual email delivery path — not just whether the records exist, but whether they're correct.
How DM1 Fixes Your Email Delivery
DM1 follows a structured process to identify and resolve email delivery problems. No guesswork — just methodical configuration against current best practice.
Audit your domain DNS records
DM1 checks your SPF, DKIM, DMARC, MX and any additional sending records using independent verification tools — not just your hosting control panel.
Check your sender reputation
We run your domain and sending IP against the major spam blacklists to see if you've already been flagged. If you have, we guide you through the removal process.
Configure missing or incorrect records
DM1 sets up or corrects SPF, DKIM and DMARC records in your DNS. For M365, we also verify your outbound connector and anti-spam policies in the Microsoft Admin Centre.
Test delivery across major providers
Once records are in place, DM1 runs test emails through Google, Microsoft and other major providers to verify they land in the inbox — not spam.
Set DMARC to enforcement mode
Once SPF and DKIM are confirmed working, DM1 moves your DMARC policy from monitoring to enforcement — stopping spoofed emails from your domain dead in their tracks.
Ongoing monitoring
DM1 monitors your email health as part of ongoing managed services. We catch problems before your clients do.
