Setting Up SPF Records for Learn Amp Emails

Sender Policy Framework (SPF) is an email authentication standard that helps prevent email spoofing. If your organisation uses custom email domains with Learn Amp, setting up SPF records ensures reliable email delivery and helps prevent Learn Amp notifications from being marked as spam.

Learn Amp partners with Mailgun for email delivery. This guide explains how to configure SPF records to authenticate emails sent through Learn Amp.

SPF records tell email servers which mail servers are authorised to send emails on behalf of your domain. When Learn Amp sends notification emails:

1. The receiving mail server checks your domain's SPF record

2. It verifies that Mailgun (Learn Amp's email provider) is authorised

3. If authorised, the email is more likely to reach the inbox rather than spam

You should configure SPF records if:

• Learn Amp emails are consistently going to spam folders

• Your organisation has strict email security policies

• You want to improve overall email deliverability

⚠️ Warning: SPF configuration requires access to your organisation's DNS settings. Work with your IT team to make these changes.

Create a new TXT record in your DNS with:

The -all mechanism indicates this SPF record is the only one used to authenticate mail for your domain.

Add Mailgun to your existing record. For example, if your current record is:

Update it to include Mailgun:

💡 Tip: Add the Mailgun inclusion before the -all or ~all mechanism at the end.

1. Wait 24-48 hours for DNS propagation

2. Use an online SPF checker tool to validate your record

3. Send a test notification and verify it reaches the inbox

Q: What's the difference between -all and ~all?
-all indicates a hard fail—emails not matching the SPF record should be rejected. ~all is a soft fail—emails may be accepted but marked as suspicious. Use -all for stricter security.

Q: Can I have multiple SPF records for one domain?
No. You must have only one SPF record per domain. If you need to authorise multiple email services, combine them into a single record.

Q: What if my SPF record has too many DNS lookups?
SPF records are limited to 10 DNS lookups. If you exceed this, consider using SPF flattening tools or consolidating your email services.

Q: How long does it take for SPF changes to take effect?
DNS changes typically propagate within 24-48 hours, though some providers may be faster.
