How to Set Up Your SPF Record
Many inbox providers use Sender Policy Framework (SPF) records to determine the legitimacy of an email address and detect domain spoofing. To ensure that your emails maintain optimal deliverability, we recommend authenticating your domain with an SPF record!
🚨 Important Note
Make sure to add only one SPF record to your domain. Multiple SPF records can cause serious delivery issues because inbox providers will not be able to tell which authentication is real.
Setting up Your SPF Record
Every domain provider has specific instructions on adding SPF records within their platform. Search your domain provider's knowledge base to find step by step instructions!
Below are generalized instructions for adding an SPF record to your domain:
- Navigate to your Domain Provider
- Locate the DNS editor/zone
- Add a record containing the following: v=spf1 mx include:_spf.sendlane.com ~all
- If prompted use the ‘@’ symbol for the host field
- Make sure to save your changes
Troubleshooting
Deliverability didn't improve after I added an SPF record!
SPF record validation can help establish your sender reputation if you're just starting out, or protect performance that's already strong. If your sender reputation is poor, SPF authentication is unlikely to improve your reputation or boost your delivery.
I use Cloudflare for hosting and can't add SPF records!
Use Cloudflare's guidance for adding TXT records. For more information, see Cloudflare's documentation.
