SPF names approved senders.
It tells recipient servers which platforms are allowed to send for your domain. A correct record includes the senders you use and avoids conflicting duplicates.
Niagara Region email authentication
SPF, DKIM, and DMARC setup that fits your real senders.
I help Niagara Region businesses authenticate email from Microsoft 365, Google Workspace, websites, CRMs, and marketing platforms—without losing track of the systems that need to keep sending.
What good setup does
Give your business a clearer sending identity.
SPF, DKIM, and DMARC are public DNS controls that help receiving mail servers confirm which email is genuinely from your business. They matter for deliverability, spoofing protection, and the confidence customers have when an important message arrives.
For businesses in St. Catharines, Niagara Falls, Welland, Fort Erie, and the wider Niagara Region, I provide direct remote support with a local point of contact. The work is the same anywhere: map the real senders, configure the correct records, verify the result, and document the setup.
The three controls
Plain-language protection for a technical problem.
DKIM signs the mail.
It lets recipients verify that a message is connected to your authorized service and has not been changed along the way.
DMARC sets the rule.
It connects the previous controls, helps reveal unauthorized use of your domain, and establishes a safe path toward enforcement.
Implementation support
Set it up once, then keep it understandable.
Inventory your senders
I identify the platforms that send as your business, including hidden sources such as web forms, invoice software, and old CRM connections.
Make the DNS changes
I provide or implement the scoped records and work with your internal technical owner or provider when access and approvals are needed.
Document the result
You receive a usable handoff: what is in place, which systems it supports, and what to revisit before adding another sender.
Start with the public records
Check your domain, then get the details right.
The free scanner can show whether the basics are visible. A scoped engagement confirms that the records match the email you actually send.
