An SPF record helps tell email providers which servers are allowed to send emails from your domain. If it is missing or incorrect, your emails may fail authentication or land in spam.
SPF stands for Sender Policy Framework. It is a DNS record that helps protect your domain by listing which mail servers are allowed to send email on its behalf.
When receiving email servers check your domain, the SPF record helps them decide whether the message appears legitimate or suspicious.
This makes SPF an important part of email authentication and delivery.
SPF issues do not always show up clearly, but these are some of the most common warning signs.
If your legitimate messages are regularly landing in junk folders, missing or weak authentication can be part of the cause.
Some systems may reject or flag messages when SPF checks fail or when the record does not match the sending service.
If you use Google Workspace, Microsoft 365, Shopify, Mailchimp or other tools together, SPF can become easy to misconfigure.
Without SPF, your domain has less protection against unauthorised senders pretending to email from your brand.
Before creating an SPF record, you need to identify every platform allowed to send on your behalf, such as Google Workspace, Microsoft 365, newsletters, CRMs or ecommerce tools.
SPF is normally added as a TXT record in your DNS settings. The record needs to reflect the services you actually use.
A common mistake is having more than one SPF record or building one that is incomplete. Either can cause authentication problems instead of fixing them.
Once updated, the setup should be checked carefully to make sure email authentication behaves as expected and no sending services were missed.
Often yes — but only if you know exactly which platforms send email from your domain and where your DNS is managed.
The tricky part is not just adding an SPF record. It is making sure it includes the right sending services, avoids duplication, stays within technical limits and works alongside DKIM and DMARC.
That is why many businesses prefer to scan the domain first, then either send the issue to their developer or let an expert configure it properly.
Cyboruz checks SPF, DKIM, DMARC, blacklist status, SSL, security headers and more — helping you spot email and website trust issues before they affect your business.
Your domain has less email trust protection, and your messages may be more likely to be flagged, filtered or questioned by receiving servers.
No. Multiple SPF records are a common mistake and can cause validation problems. SPF should be combined into a single correct record.
SPF is important, but it works best alongside DKIM and DMARC as part of a stronger overall email authentication setup.
Yes. Cyboruz checks key email security signals including SPF, helping you identify missing or weak authentication before it causes bigger delivery problems.
