While working on the projects, we might have a requirement to send emails to a set of recipients programmatically. For this, we usually use the SMTP server created at the client end for sending the emails, which involves a considerable amount of cost and maintenance of servers for the client. However, if we have to deal with low cost, low maintenance and also hold an Azure Subscription, then we can go about using the SendGrid Email Delivery Service available in Microsoft Azure.

What is SendGrid?
SendGrid is a cloud-based SMTP provider used to deliver marketing and transactional emails. SendGrid maintains email server on your organization’s behalf, so your messages are sent and delivered as needed.

SendGrid manages all of the technical requirements, from infrastructure to ISP outreach and monitoring to whitelist services and real-time analytics. It’s the world’s largest cloud-based service for delivering emails.
