Xamarin.Forms - Send Email using AWS SES(Simple Email Service)

In this blog post,  you will learn how to send background Email using AWS(Amazon Web Services) SES(Simple Email Service) in Xamarin forms. 

Introduction

Xamarin.Forms code runs on multiple platforms - each of which has its own filesystem. This means that reading and writing files is most easily done using the native file APIs on each platform. Alternatively, embedded resources are a simpler solution to distribute data files with an app.

SMTP (Simple Mail Transfer Protocol)

Use SMTP to send and receive mail messages. SMTP provides a set of protocols that simplifies the communication of email messages between email servers. It is an Internet standard for electronic mail (email) transmission. SMTP is a part of the application layer of the TCP/IP protocol. The default TCP port used by SMTP is 25 and the SMTP connections secured by SSL, known as SMTPS, uses the default to port 465. Most SMTP server names are written in the form "smtp.domain.com" or "mail.domain.com": for example, a Gmail account will refer to smtp.gmail.com the Gmail port number is 587.

AWS SES(Simple Email Service)

Amazon Simple Email Service (Amazon SES) is a cloud-based email sending service designed to help digital marketers and application developers send transactional emails. It is an Internet standard for electronic mail (email) transmission. uses the default to port 25, 465 or 587. You can use our SMTP interface or one of the AWS SDKs to integrate Amazon SES directly into your existing applications. SES is available Transport Layer Security (TLS).
