Email is a headache! Here are a couple tools I use to verify SPF records, DKIM records, etc: http://www.openspf.org/Tools http://www.openspf.org/Tools and http://www.kitterman.com/spf/validate.html http://www.kitterman.com/spf/validate.html and http://dkimcore.org/tools/dkimrecordcheck.html http://dkimcore.org/tools/dkimrecordcheck.html Also, you might learn about warming up an IP address for mail sending if you're going to be pushing volume: http://docs.sendgrid.com/documentation/get-started/sending-practices-limitations/warming-up-your-ip-address/ http://docs.sendgrid.com/documentation/get-started/sending-p... Sendgrid's reputation checking and interface for seeing and clearing bounces, spam reports, etc. are extremely useful too. I imagine you already know all this, but others may not :)

In our case, gmail was deciding the email was spam. As a rsult it doesnt get reported to sendgrid. It makes sense from googles point of view. If they reported it to the sender it would be easier for spammers to learn how to work around it.

  > If they reported it to the sender it would be easier for spammers to learn how to work around it. Of course, it would also mean those of us sending legitimate e-mails that get canned by these ever-more-aggressive spam filters know that someone did not receive the information they asked us for so we can do something about it. Silent failure breaks e-mail. It is irresponsible, and the damage due to not getting a legitimate message through can be far greater than the damage due to letting a spam through (which you wouldn't be anyway, the spammer would just know they're not making it).
