MailGun TXT record on "www" is a duplicate to CNAME

Question

I am using Google DNS and already have a CNAME record for www to example.com. MailGun requires us to have a TXT record on hostname www.example.com for the SPF record: v=spf1 include:mailgun.org ~all

Google DNS complains that www is already used by CNAME and thereby cannot be used for TXT. Anybody with a similar experience? How did you overcome it?

Answer 1

You intend to send mails from @www.example.com? If you do not have an SPF record for example.com you can create this one, the CNAME record you have means that www.example.com will automatically have the same SPF as example.com, because CNAME means "absolutely the same as" or "alias of"
