I recently learned about the importance of having an SPF record. I read in this article from Google ( that the record should include an IP address. When I read your article about setting it up ( there was no mention of including an IP address. Additionally Google says to use ~all while your article says to use -all. Could you please clarify this as I am concerned about setting it up wrong? Thank you.

Hi there,

It looks like the google document you linked to is specific to google apps users who want to setup google as an authorized sender for mailings.  Those instructions don't really apply to Emma.  

I would like to talk a bit about the difference between -all and ~all.  The - vs. ~ is the instructions for what you should do for any domain or IP addresses not listed in the SPF record.  For v/spf1 = -all you're being told that anything other than emma's domain is a hard spf fail and not authorized to send on your behalf.  That doesn't mean that your message will bounce, but it will fail the SPF check.

If you look at the same record, but with ~all at the end, you're being told that anything other than the emma domain is not authenticated, but still might be legit.  This would be a soft fail on the SPF check.  You can use either -all or ~all and your sending through Emma will not be negatively affected.

You shouldn't have any trouble if you use our SPF instructions to setup Emma as your authorized user.  

Let us know if this doesn't work for you.  We're always happy to help.
