If you’re doing sales outreach through the Office 365 interface, you need SPF.
Why?
SPF adds a layer of security to your emails, directly leading to better open rates.
And with more eyeballs on your emails, you’ll generate more revenue for your business.
After reading this post, you’ll know exactly how to set up an SPF record for Office 365.
SPF Explained
If you Google “SPF,” most results will be related to sunscreen. As you already figured out, that’s not what this is about. ;-)
Instead, SPF is an email authentication protocol that stands for: Sender Policy Framework.
SPF allows you to authorize email servers that can send email on your domain’s behalf.
Most of the time, you’d authorize the sending server of your email service provider to send through your domain. In this case, Office 365.
So, how does SPF work in practice?
When an email claims to come from your domain, the receiving server checks your domain’s SPF record.
The email will pass authentication if the sending server is indeed in your SPF record. If it's not, the SPF authentication will fail, and the email will get sent to spam or not be delivered at all.
SPF Record Example
Let’s take a look at the standard SPF record for Office 365:
Here’s what it all means:
💡 The V stands for version. There’s only one SPF version in use currently
💡 The Include tag holds the authorized sending server
💡 The All tag defines the result that should be returned when an email fails authentication. The record above states that emails failing authentication should be rejected outright.
Can you have multiple SPF records?
No, SPF only supports one record per domain.
If your domain has multiple SPF records, it will cause errors when authenticating emails.
The good news is that you can authorize multiple sending servers (or IPs).
How?
By adding multiple Include tags to your SPF record, like this:

The Hidden Step: Validating Your SPF Record
After saving your record, it won’t be active immediately.
In fact, it can take up to 72 hours for your record to become visible.
But don’t worry, typically your record will propagate in a few hours.
To check the status of your SPF record, use MXToolbox. Just enter your domain and select the SPF Record Lookup option.
Work Not Done Yet
While setting up your SPF is a big step toward better open rates, SPF alone is not enough.
The SPF protocol works best in combination with two other email authentication methods: DKIM and DMARC.
Together, these three email authentication tools can boost your sales email engagement and, ultimately, your revenue.
Make sure to set up all three before you start your outreach.
