Email security & deliverability in Avondale
Email is where most attacks start and where most business is still done. We filter out the phishing and fake invoices before staff see them, lock down your domain so nobody else can send as you, and fix the settings that send your own mail to clients' junk folders.
Onsite technicians cover Avondale. Most problems are fixed remotely first; when a job needs hands, a technician comes to you.
Email security & deliverability for Avondale businesses
Avondale's Rosebank Road peninsula is a long-established industrial area with food producers, manufacturers, engineering firms and importers, while the town centre on Great North Road has retail, services and family businesses. Many companies here have grown over decades on the same site.
Long-held industrial sites tend to have IT that grew in layers: phone cabling reused for data, switches in a dusty factory cabinet and production computers running old Windows versions because a machine depends on them. Sorting that out means documenting what exists, isolating old systems from the internet and planning upgrades without stopping production.
Both have the same root. Email was designed long before anyone worried about forgery, so proving who sent a message depends on a handful of DNS records and filtering settings that most small businesses have never had set up properly. SPF lists the services allowed to send for you, DKIM signs your messages and DMARC tells other mail servers what to do with anything that fails. Big mail providers now expect all three from business senders.
Technicians attend Rosebank Road and town centre sites for networks, cabling and computers, and we fix most issues remotely. Changes near production equipment are planned with your team and quoted first.
What's included
Phishing and malware filtering
Incoming mail scanned for malicious links, attachments and fake sign-in pages, with links checked again when they are clicked.
Impersonation protection
Rules that flag mail pretending to come from your directors, your domain or lookalike domains with a letter swapped.
DMARC rollout
A reporting-only policy first, then a gradual move to quarantine and reject once reports show all your genuine mail passes.
External sender warnings
A clear banner on mail from outside the company, so a message using the boss's name from a free email account stands out.
SPF records
One correct SPF record listing every service that legitimately sends for you, kept within the lookup limits that break many records.
Junk folder fixes
We trace why your mail is being filtered, from missing records to a listed address or a website form sending as you, and correct it.
Is it right for your Avondale office?
Email security is worth a look if:
- Clients tell you your invoices or quotes end up in junk
- Someone received a fake invoice that appeared to come from your address
- Staff are getting convincing fake Microsoft sign-in emails
- You don't know whether your domain has SPF, DKIM or DMARC
- A large client or bank has asked you to set up DMARC
How getting started works
- Free IT health check. We look at your devices, accounts, backups and network and tell you what we find, in plain English.
- Clear proposal. A written monthly price per user and a list of any fixes, with nothing hidden.
- Handover. We collect admin access and documentation from your current provider and keep your team working.
- Day-one fixes. Security gaps, failed backups and urgent risks are dealt with first.
Email security & deliverability in Avondale: questions
We have an old PC that runs a factory machine. Can it stay?
Often it has to, because the machine software needs it. We isolate it on its own network so it cannot reach the internet or the office systems, back up what we can and plan a replacement when the vendor supports one.
Our factory cabling is a mess. Where do we start?
With a survey: we trace, test and label what is there, find what is unsafe or failing and propose a tidy structure in priority order. Any recabling is quoted in writing before work starts.
Why does our email go to junk?
Common causes are a missing or broken SPF record, no DKIM signing, a website or app sending as your domain without permission, or a shared sending address with a poor reputation. We check each one and fix the cause.
How long does it take to set up?
Filtering and records are usually set in a day or two. Moving DMARC to full enforcement normally takes a few weeks of watching reports, so nothing legitimate is caught.
What are SPF, DKIM and DMARC in plain English?
SPF is a list of who can send email for your domain. DKIM is a digital signature on each message. DMARC ties them together and tells receiving servers whether to accept, quarantine or reject mail that fails, and sends you reports about it.
Will turning on DMARC stop our own emails?
It can if it is rushed. That is why we start in reporting mode, find every service sending as you and only tighten the policy when the reports show your genuine mail passing.
