Running your own SMTP server is difficult. If you have ever tried to send transactional emails like friend requests, password reminders, sign-up verifications or purchase receipts from your web app, you already know how frequently they get labeled as spam. Without these timely triggered email messages, your application won't function properly, and your customer satisfaction will drop - or worse yet, your customers will leave!

The do-it-yourself route is complicated and expensive. You typically have little to no insight into whether your transactional email is bouncing, hitting the spam folder or even being delivered at all. Our SMTP service manages this entire process through a reliable cloud email infrastructure. SendGrid maintains real SMTP relay servers for you, so that you won't have to worry about deliverability and scalability. Plus, you get precise, real-time analytics to help manage the entire process. Integrate with SendGrid's SMTP relays by changing three simple settings, and you'll be delivering email in minutes. Whether you just want to use SendGrid's SMTP email server or work on deeper, custom integration through our various APIs, we have an app mail server solution for your company.
