How to Add SPF Entries to Your Sendmarc-Managed Domain
SPF is an email authentication protocol that allows domain owners to specify the individual IP addresses, IP ranges, and sending services authorized to send email on their behalf, so receiving servers can verify the source of incoming email.
Pre-Requisites
In order to complete the steps below, you will need to have Administrator permissions in Sendmarc.
This guide will assume that you are attempting to authorize Office 365 to send on your behalf, but the process is the same regardless of provider (only the specific entry changes).
When setting up a domain in Office 365, you are required to add the following entry to your SPF:
| Host | Type | Value |
|---|---|---|
@ | TXT | v=spf1 include:spf.protection.outlook.com ~all |
Steps in Sendmarc
Performing this action on Sendmarc is simple - just follow these steps:
- Log in to the Sendmarc Portal.

- Click ‘Add New SPF Directive’.
- Under ‘Type,’ select the provided value. In the above example, this is ‘include’.
