Krajem 12. mjeseca smo odradili intervju za novogodišnji VIDI časopis, a teme su bile edukacija u Algebri, slijedni poslovni poduhvati te upotreba klasično stečenog znanja iz Algebra kod razvoja web i mobilnih aplikacija. Kupite svoj VIDI primjerak…još malo pa nestalo ;)

Amazon Simple Email Service (Amazon SES) is a highly scalable and cost-effective bulk and transactional email sending service for businesses and developers. Amazon SES eliminates the complexity and expense of building an in-house email solution or licensing, installing, and operating a third-party email service for this type of email communication. In addition, the service integrates with other AWS services, making it easy to send emails from applications being hosted on AWS. With Amazon SES there is no long-term commitment, minimum spend or negotiation required – businesses can utilize a free usage tier, and beyond that pay only low fees for the number of emails sent plus data transfer fees. You can find out more at official AWS SES page.

Here are some of the code snippets in C# (ASP.NET 4.0) but they will also work on earlier .NET versions. Please note that we developed this codes on top of AWS SDK for.NET! This libraries are important for code snippets to work so please implement them in your project before you start to copy & paste :)

First we need to insert AKID and secret key into our Configuration file This step is important as it gives you a one point of contact for your access credentials and it is also much safer

List Verified Emails Script (Verified emails are valid addresses from which you can send mass emails)

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Configuration;
using Amazon.SimpleEmail;
using Amazon.SimpleEmail.Model;

public partial class ListVerifiedEmails : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//INITIALIZE AWS CLIENT/////////////////////////////////////////////////////////
AmazonSimpleEmailServiceConfig amConfig = new AmazonSimpleEmailServiceConfig();
amConfig.UseSecureStringForAwsSecretKey = false;
AmazonSimpleEmailServiceClient amzClient = new AmazonSimpleEmailServiceClient(ConfigurationManager.AppSettings["AKID"].ToString(), ConfigurationManager.AppSettings["Secret"].ToString(), amConfig);

//LIST VERIFIED EMAILS/////////////////////////////////////////////////////////
ListVerifiedEmailAddressesRequest lveReq = new ListVerifiedEmailAddressesRequest();
ListVerifiedEmailAddressesResponse lveResp = amzClient.ListVerifiedEmailAddresses(lveReq);
ListVerifiedEmailAddressesResult lveResult = lveResp.ListVerifiedEmailAddressesResult;

foreach (Object email in lveResult.VerifiedEmailAddresses)
{
Response.Write(email.ToString()+"
");
}
}
}

Verify email (Verified emails are valid addresses from which you can send mass emails)

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Configuration;
using Amazon.SimpleEmail;
using Amazon.SimpleEmail.Model;

public partial class VerifyEmail : System.Web.UI.Page

//VERIFY EMAIL/////////////////////////////////////////////////////////
VerifyEmailAddressRequest veaRequest = new VerifyEmailAddressRequest();
veaRequest.EmailAddress = "INSERT_EMAIL_TO_VERIFY_HERE";
VerifyEmailAddressResponse veaResponse = amzClient.VerifyEmailAddress(veaRequest);
Response.Write(veaResponse.ResponseMetadata.RequestId);
}
}

Get sending quota limits

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Configuration;
using Amazon.SimpleEmail;
using Amazon.SimpleEmail.Model;

public partial class GetQuota : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//INITIALIZE AWS CLIENT/////////////////////////////////////////////////////////
AmazonSimpleEmailServiceConfig amConfig = new AmazonSimpleEmailServiceConfig();
amConfig.UseSecureStringForAwsSecretKey = false;

//GET SENDING QUOTA/////////////////////////////////////////////////////////
GetSendQuotaRequest gsqReq = new GetSendQuotaRequest();
GetSendQuotaResponse gsqResp = amzClient.GetSendQuota(gsqReq);
GetSendQuotaResult gsqResult = gsqResp.GetSendQuotaResult;

Response.Write("Max 24 hour send limit: " + gsqResult.Max24HourSend.ToString() + ";
Max send rate: " + gsqResult.MaxSendRate.ToString() + ";
Send last 24 hours: " + gsqResult.SentLast24Hours.ToString());
}
}

Get sending statistics (Bounces, Complaints, Deliveries, Rejects…from last two weeks)

using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Configuration;
using Amazon.SimpleEmail;
using Amazon.SimpleEmail.Model;

public partial class GetSendStatistics : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//INITIALIZE AWS CLIENT/////////////////////////////////////////////////////////
AmazonSimpleEmailServiceConfig amConfig = new AmazonSimpleEmailServiceConfig();
amConfig.UseSecureStringForAwsSecretKey = false;
AmazonSimpleEmailServiceClient amzClient = new AmazonSimpleEmailServiceClient(ConfigurationManager.AppSettings["AKID"].ToString(), ConfigurationManager.AppSettings["Secret"].ToString(), amConfig);

//GET SEND STATISTICS/////////////////////////////////////////////////////////
GetSendStatisticsRequest gssReq = new GetSendStatisticsRequest();
GetSendStatisticsResponse gssResp = amzClient.GetSendStatistics(gssReq);
GetSendStatisticsResult gssResult = gssResp.GetSendStatisticsResult;

foreach (SendDataPoint sdp in gssResult.SendDataPoints)
{
Response.Write("BOUNCES:" + sdp.Bounces.ToString() + "; COMPLAINTS:" + sdp.Complaints.ToString() + "; DELIVERY ATTEMPTS:" + sdp.DeliveryAttempts.ToString() + "; REJECTS:" + sdp.Rejects.ToString() + "; DateTime:" + sdp.Timestamp.ToLongDateString() + " - " + sdp.Timestamp.ToLongTimeString() + "

");
}
}
}

Send email-to-many (You can only send emails from verified addresses). Please note that your sending quota applies here and that you can send to max. 50 emails in one method call. That means you must divide your email array / que / sendinglist in groups of 50 by 50. PLEASE STUDY QUOTA MANAGEMENT BEFORE SENDING MASS EMAILS

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Configuration;
using Amazon.SimpleEmail;

//INITIALIZE AWS CLIENT/////////////////////////////////////////////////////////
AmazonSimpleEmailServiceConfig amConfig = new AmazonSimpleEmailServiceConfig();
amConfig.UseSecureStringForAwsSecretKey = false;
AmazonSimpleEmailServiceClient amzClient = new AmazonSimpleEmailServiceClient(ConfigurationManager.AppSettings["AKID"].ToString(), ConfigurationManager.AppSettings["Secret"].ToString(), amConfig);

ArrayList to = new ArrayList();

//ADD AS TO 50 emails per one sending method//////////////////////
to.Add("INSERT EMAIL 1 HERE");
to.Add("INSERT EMAIL 2 HERE");

//ADD AS TO 50 emails per one sending method/////////////////////
Destination dest = new Destination();
dest.WithBccAddresses((string[])to.ToArray(typeof(string)));
string body = "INSERT HTML BODY HERE";
string subject = "INSERT EMAIL SUBJECT HERE";
Body bdy = new Body();
bdy.Html = new Amazon.SimpleEmail.Model.Content(body);
Amazon.SimpleEmail.Model.Content title = new Amazon.SimpleEmail.Model.Content(subject);
Message message = new Message(title, bdy);
SendEmailRequest ser = new SendEmailRequest("VERIFIED_EMAIL_HERE", dest, message);
SendEmailResponse seResponse = amzClient.SendEmail(ser);
SendEmailResult seResult = seResponse.SendEmailResult;
}
}

What are your send methods and codes? Do you have some advice or experience from SES? Please tell us and share stories in the comments!

Happy coding :)

UPDATE: Amazon has extensively updated their Admin panel so you can now perform various checks on bounces, deliveries, complaints and rejects without API coding.  Also, you can setup SMTP access for SES and verify new senders. So head on to the official AWS management console and see all of the cool features for yourself!
