BTW, don't use SendGrid unless you intend to pay them lots of money for a dedicated IP. I've been using them for a couple of years now and it's extremely frustrating, because they are used by spammers and do not react quickly enough or simply do not care. Some of your E-mails will end up sent from IPs that landed in various anti-spam blackhole systems already and will never reach their destination.
This happens regularly and makes SendGrid totally useless for transactional E-mail (I prefer to send it myself) and problematic for things like product updates.
I complained to them about this problem many times and it is my impression that this is a way to force-upsell customers to higher plans with dedicated IPs.
