Since 1998 we’ve sent email from our application using our own, very reliable, SMTP servers. And while it has worked great, it is nowhere near as robust as SendGrid, a cloud-based email delivery and management service whose goal is to increase delivery and improve customer communications.
SendGrid has revolutionized the delivery of email from our applications because it allows us to know what happens to each and every email that leaves us. Was the message undeliverable because the email address was invalid? Did it bounce for some reason? Did the consumer mark it as Spam? SendGrid will tell you this and much more about every message sent from your application.
