How many times can I use the SPF generator?
You can use it as many times as you need.
Can I add multiple providers to my SPF record?
Yes, just click all the email service providers you send email with.
Do you have generators for other email authentication protocols?
Yes, we have a DMARC generator too.
What happens to an email if it fails SPF authentication?
You can decide what happens to them by setting up a valid DMARC record. Receiving servers will typically follow the policy you set in your DMARC record. DMARC's three main policies are None (email gets a pass), Quarantine (email gets sent to spam), and Reject (email won't get delivered at all).
What happens if I send from a service not included in my SPF record?
Your emails will fail authentication and likely get sent to spam or not get delivered at all.
