SPF Configuration
SPF (Sender Policy Framework) is a DNS record that prevents spammers from sending emails using your domain (yourdomain.com).
What is SPF?
When an email is sent from your domain, the recipient's mail server checks your SPF record to verify if the sending server is authorized by you. If the server is not on the list, the email may be marked as spam or rejected entirely.
Step 1: Get Your SPF Record
Log in to Simply Send, go to the Domains page, select your domain, and navigate to the DNS Records page. Under the Email Authentication section, you will find your pre-generated SPF record.
Step 2: Add DNS TXT Record
DNS Record Type & Name
Type: TXT
Name/Host: yourdomain.com
Why It's Needed
This tells receiving email servers that Simply Send is officially authorized to send emails matching your domain name, preventing them from being flagged as spoofed spam.
How to Update It
Before adding any new records, you must verify if you already have an SPF record. Log in to your DNS provider (e.g., Cloudflare, GoDaddy, Route53) and check your existing TXT records on the root domain (usually denoted by @ or left blank). Look for any record that begins exactly with v=spf1. Depending on what you find, follow one of the scenarios below:
Pro Tip: Not sure if you have an SPF record? You can enter your domain on MxToolbox or open your computer's terminal and type dig TXT yourdomain.com to check!
AIf you don't have an SPF record
Add a brand new TXT record containing the exact value provided in your dashboard:
BIf you already have an SPF record
Do not create a second SPF record! Doing so will cause both to fail. Instead, edit your existing record and insert the Simply Send requirements (include:amazonses.com include:spf.oraclecloud.com) right before the ~all or -all tag.
Multiple Email Services?
Important: You can only have one SPF record per domain. If you use multiple services (e.g., Simply Send and Google Workspace), you must combine them into a single record.

Step 3: Verify and Enable
Wait for Propagation
DNS changes can take anywhere from a few minutes to 24 hours to update globally.
Enable in Console
Once the DNS check passes, click "Verify" in your Simply Send dashboard to activate your domain.
Common SPF Issues
Multiple SPF Records
Having two separate TXT records starting with `v=spf1` will cause permanent failures (PermError).
Too Many DNS Lookups
SPF limits records to 10 DNS lookups. Too many `include:` statements will break verification.
Next Step: Digital Signatures (DKIM)
Encrypt your email headers with DKIM to ensure messages are not tampered with during transit.
