Amazon SES – How to track email deliverability to domain level with CloudWatch

Post Syndicated from Alaa Hammad original https://aws.amazon.com/blogs/messaging-and-targeting/amazon-ses-how-to-track-email-deliverability-to-domain-level-with-cloudwatch/

Why is it important to track email deliverability per domain with Amazon Simple Email Service (SES)?

Amazon Simple Email Service (Amazon SES) is a scalable cloud email service provider that enables businesses to build a large-scale email solution and host multiple domains from the same SES account for different purposes ex: one domain for sending marketing emails such as special offers, another domain to send transactional emails such as order confirmations, and other types of correspondence such as newsletters.

As your product, service or solution built on Amazon SES grows and you require multiple domains verified, it is important to track email deliverability for emails you send from each domain for business continuity, billing purposes or incidents investigations. This can be useful to identify if you have low email deliverability for your business domain or if you have a domain generating high bounce or complaint rates and take proactive actions before impacting the account’s ability to send emails from any other domains.

SES offers features that automatically manage deliverability per domain through Virtual Deliverability Manager. Virtual Deliverability Manager helps enhance email deliverability and provides insights into sending and delivery data, as well as offering solutions to fix negative email sending reputation. You can learn more about Virtual Deliverability Manager here.

Solution Walkthrough

Amazon SES provides a way to monitor sender reputation metrics such as bounce and complaint rates per account or configuration sets using event publishing. This blog will discuss how you can use Amazon SES message auto-tags to monitor and publish email deliverability events (Send, Delivery, Bounce, Complaints) to CloudWatch custom metrics per domain. In addition, you will see how to create a custom CloudWatch dashboard that’s easy to access in a single view to monitor your domain metrics. This CloudWatch dashboard can help to provide guidance for your team members during operational events about how to respond to specific incidents for your sending domain.

What are Amazon SES Auto-Tags:

Message tags are a form of name/value pairs to categorize the email you are sending. For example, if you advertise books, you could name a message tag general, and assign a value of sci-fi or western, when you send an email for the associated campaign. Depending on which email sending interface you use, you can provide the message tag as a parameter to the API call (SendEmail, SendRawEmail) or as an Amazon SES-specific email header.

In addition to the message tags you add to any emails you send, Amazon SES adds a set of Auto-Tags that are automatically included in any emails you send. You don’t need to pass the parameters of the auto-tags to the API call or email headers since SES does this automatically.

The auto-tags in the list below are used to track the email deliverability for specific events ( ex: Send, Delivery, Bounce, Complaint). SES does this by using the name/value pairs of the auto-tag name as a dimension in CloudWatch metric to track the count of events of specific auto-tag. This blog post will use “ses:from-domain” auto-tag to configure event publishing for tracking and publish email deliverability events (Send, Delivery, Bounce, Complaints) you receive per domain to CloudWatch metrics and CloudWatch dashboard.

Amazon SES auto-tags added to messages you send

Prerequisites:

For this walkthrough, you should have the following prerequisites:

Configure Amazon SES to publish email deliverability events to CloudWatch destination:

To configure event publishing for tracking email deliverability events, you first need to create a configuration set. Configuration sets in SES are groups of rules, that you can apply to your verified identities. When you apply a configuration set to an email, all of the rules in that configuration set are applied to the email.

After your configuration set is created, you need to create Amazon SES event destination. Amazon SES will send all email deliverability events you intend to track to this event destination. In this blog the event destination is Amazon CloudWatch.

    1. Sign in to the Amazon SES console.
    2. In the navigation pane, under Configuration, choose Configuration sets. Choose Create set.
    3. Enter Configuration set name, leave the rest of fields to default, scroll to the send and click on Create set.
    4. Under configuration set home page click on Event destinations tab and select Add destination
    5. Add SES event destination to configuration set
    6. Under Select event types, check Sends, Deliveries, Hard bounces and Complaints boxes and click Next.
    7. selecting event types to track
    8. Under Specify destination, Select Amazon CloudWatch.
    9. Select event destination as Amazon CloudWatch
    10. Name – enter the name of the destination for this configuration set. The name can include letters, numbers, dashes, and hyphens. (example : Tracking_per_Domain)
    11. Under Amazon CloudWatch dimensions, Select Value source: Message tag , Dimension name: ses:from-domain and Default value: example.com (you will need to add the verified domain name you want to track) as shown below:
    12. add message auto-tag as CloudWatch dimension to track
    13. Review, When you are satisfied that your entries are correct, Click Add destination to add your event destination.

Send a test email via Amazon SES mailbox simulator to trigger events in CloudWatch custom metric.

After selected Amazon CloudWatch as event destination , Amazon CloudWatch will create a custom metric with the auto-tag dimension and value you chose. For this custom metric to appear in CloudWatch Console, you must send an email to trigger each selected event. We recommend using the Amazon SES Mailbox Simulator to avoid generating real bounces or complaints that could impact your account’s reputation.

In the below section, This blog will show how to send those test emails to the following recipients manually using CLI. If you would like to use the console method to send those emails. you will need to send three separate test emails since the console will only allow one recipient per message:

Amazon SES Mailbox Simulator recipients to trigger the events in CloudWatch metrics:
[email protected]
[email protected]
[email protected]

Note: You must pass the name of the configuration set when sending an email. This can be done by either specifying the configuration set name in the headers of emails, or specifying it as a default configuration set. This can be done at the time of identity creation, or later while editing a verified identity.

The following example uses send-emailCLI command to send a formatted email to the Amazon SES simulator recipients:

Before you run any commands, set your default credentials by following Configuring the AWS CLI. The IAM user must has “ses:SendEmail” permission to send email.

  1. Navigate to your terminal where the AWS CLI is installed and configured. Create message.json file for the message to send and add the following content:
  2. {
    "Subject": {
    "Data": "Testing CW events with email simulator",
    "Charset": "UTF-8"
    },
    "Body": {
    "Text": {
    "Data": "This is the message body of testing CW events with email similulator.",
    "Charset": "UTF-8"
    }
    }
    }
  3. Create a destination.json file to add Amazon SES simulator recipients for bounces, complaints and delivery events as shown below:
  4. { 
    
    "ToAddresses": ["[email protected]", "[email protected]" , "[email protected]"]
    
    }
  5. Send a test email using send-email CLI command to send a formatted email to the Amazon SES simulator recipients:
  6. aws ses send-email --from [email protected] --destination file://destination.json --message file://message.json --configuration-set-name SES_Config_Set --region <AWS Region>
  7. After the message sent, you are expected to see the following output:
  8. {
    
    "MessageId": "EXAMPLEf3a5efcd1-51adec81-d2a4-4e3f-9fe2-5d85c1b23783-000000"
    
    }

Now you sent a test email to trigger the events you want to track in CloudWatch custom metrics. Lets create the CloudWatch dashboard to see those metrics.

Create CloudWatch dashboard to track the email deliverability events for my domain.

  1. Sign in to the Amazon CloudWatch console.
  2. In the navigation pane, choose Dashboards, and then choose Create dashboard.
  3. In the Create new dashboard dialog box, enter a name like ‘CW_Domain_Tracking’ for the dashboard, and then choose Create dashboard.
  4. In the Add Widget dialog box, Choose Number to add a number displaying a metric to the dashboard and then choose Next
  5. Under Add metric graph, click on edit sign to rename the graph with your domain example.com . this will make it easy for you to select the dashboard of the domain if you have multiple domains.
  6. In the Browse tab , Select the AWS region where you are running your SES account and in the search bar, search for “ses:from-domain”.
  7. You will get four metrics returned with your domain name “example.com”. Select checkbox beside the four metrics and click Create widget.
  8. CloudWatch dashboard with the metrics
  9. Save dashboard in the top right corner of the dashboard page to save the widget settings.
  10. Save CloudWatch dashboard settings

After the CloudWatch dashboard created, for any email you send from example.com domain with configuration set name passed in the email header, The email deliverability events will be counted in your CloudWatch metrics and you will be able to see them in the CloudWatch dashboard.

As an additional step. You can also setup a CloudWatch alarms for this custom metrics and add a threshold for each metric. When the metric breach the threshold, the alarm goes on and send an SNS notification to you to take the necessary actions.

Cleaning Up:

This setup includes Amazon CloudWatch and Amazon SES service charges. To avoid incurring any extra charges, remember to delete any resources created manually if you no longer need them for monitoring.

Resources to delete from Amazon SES console.

  1. In the navigation pane, under Configuration, choose Configuration sets.
  2. Check the box beside Configuration set you created and select Delete.

Resources to delete from Amazon CloudWatch console.

  1. In the navigation pane, choose Dashboards, and then choose the dashboard you created.
  2. In the upper-right corner of the graph that you want to remove, choose Actions, and then choose Delete Dashboard.
  3. Save dashboard.

Conclusion:

You have now seen how to configure Amazon SES to track email deliverability at domain level with CloudWatch dashboard. Tracking email deliverability for emails you send from each domain is essential for business continuity, billing purposes or incidents investigations. Using SES message auto-tags and CloudWatch metrics you can identify the domains that have low email deliverability quickly and take necessary actions to maximize your email deliverability and take proactive actions before impacting the account’s ability to send emails from any other domains.

What is BIMI and how to use it with Amazon SES

Post Syndicated from Matt Strzelecki original https://aws.amazon.com/blogs/messaging-and-targeting/what-is-bimi-and-how-to-use-it-with-amazon-ses/

Introduction

In this blog post I’d like to walk you through how to implement BIMI while using Amazon SES. For your information BIMI can be best described by the following excerpt from bimigroup.org:

Brand Indicators for Message Identification or BIMI (pronounced: Bih-mee) is an emerging email specification that enables the use of brand-controlled logos within supporting email clients. BIMI leverages the work an organization has put into deploying DMARC protection, by bringing brand logos to the customer’s inbox. For the brand’s logo to be displayed, the email must pass DMARC authentication checks, ensuring that the organization’s domain has not been impersonated.

Brands continually need to protect themselves from spoofing and phishing from bad actors who can damage the trust that customers and recipients have in those brands. Brand Indicators for Message Identification (BIMI) is an email specification that enables email inboxes to display a brand’s logo next to the brand’s authenticated email messages within supporting email clients. BIMI is an email specification that’s directly connected to authentication, but it’s not a standalone email authentication protocol as it requires all your email to comply with DMARC authentication. Recipients are more likely to engage with email that displays the logo of the brand associated with the message author. Higher engagement helps deliverability and inbox placement because it indicates that the recipients trust your brand. BIMI is a great brand protector in email and provides a better user experience for the end recipients and customers.

BIMI requires that you authenticate all of your organization’s email with SPF, DKIM and DMARC. In this how-to we will be utilizing Amazon SES to authenticate the emails, Amazon S3 to host the SVG image, and Amazon Route53 to add DNS records. We will be walking through how to accomplish each step until completion.

Note: While we’re using AWS products in this how-to, it is not a requirement to use all AWS products to implement BIMI. Any hosting provider for content or domain can be used however the steps may differ based on the provider you use.

BIMI Implementation

The following are the steps needed to prepare your SES account and domain for BIMI:

Step 1

Note: If you already have SPF, DKIM, and DMARC enabled for your domain (with 100% as the rate for DMARC) you can move on to Step 2.

Enable Easy DKIM for your domain

  1. Sign in to the AWS Management Console and open the Amazon SES console at https://console.aws.amazon.com/ses/.
  2. In the navigation pane, under Configuration, choose Verified identities.
  3. In the list of identities, choose an identity where the Identity type is Domain.

Note: If you need to create or verify a domain, see Creating a domain identity.

  1. Under the Authentication tab, in the DomainKeys Identified Mail (DKIM) container, choose Edit.
  2. In the Advanced DKIM settings container, choose the Easy DKIM button in the Identity type field.
  3. In the DKIM signing key length field, choose either RSA_2048_BIT or RSA_1024_BIT.
  4. In the DKIM signatures field, check the Enabled box.
  5. Choose Save changes.
  6. Now that you’ve configured your domain identity with Easy DKIM, you must complete the verification process with your DNS provider – proceed to Verifying a DKIM domain identity with your DNS provider and follow the DNS authentication procedures for Easy DKIM.

Create a DMARC record for your domain

  1. Sign in to the AWS Management Console and open the Route 53 console at https://console.aws.amazon.com/route53/
  2. In the navigation pane, choose Hosted zones.
  3. On the Hosted zones page, choose the name of the hosted zone that you want to create records in.
  4. Choose and define the applicable routing policy and the following values:
Name Record Type Value
_dmarc.example.com TXT v=DMARC1;p=quarantine;pct=100;rua=mailto:[email protected]
  1. Choose Create records.

Note: The DMARC policy must enforce at 100% and include either a quarantine or reject policy. (i.e. p=reject or p=quarantine) to meet the DMARC authentication requirement. This may mean you will need to update your existing policy and DMARC record.

Configure a Custom Mail From for your sending domain

  1. Open the Amazon SES console at https://console.aws.amazon.com/ses/.
  2. In the left navigation pane, under Configuration, choose Verified identities.
  3. In the list of identities, choose the identity you want to configure where the Identity type is Domain and Status is Verified.

a. If the Status is Unverified, complete the procedures at Verifying a DKIM domain identity with your DNS provider to verify the email address’s domain.

  1. At the bottom of the screen in the in the Custom MAIL FROM domain pane, choose Edit .
  2. In the General details pane, do the following:

a. Select the Use a custom MAIL FROM domain checkbox.

b. For MAIL FROM domain, enter the subdomain that you want to use as the MAIL FROM domain.

c. For Behavior on MX failure, choose one of the following options:

    • Use default MAIL FROM domain – If the custom MAIL FROM domain’s MX record is not set up correctly, Amazon SES uses a subdomain of amazonses.com. The subdomain varies based on the AWS Region that you use Amazon SES in.
    • Reject message – If the custom MAIL FROM domain’s MX record is not set up correctly, Amazon SES returns a MailFromDomainNotVerified error. Emails that you attempt to send from this domain are automatically rejected. If you want to ensure that 100% of your email is BIMI compatible, then you should choose the reject message option.

d. Choose Save changes – you’ll be returned to the previous screen.

  1. Publish the MX and SPF (type TXT) records to the DNS server of the custom MAIL FROM domain:

Note: In the Custom MAIL FROM domain pane, the Publish DNS records table now displays the MX and SPF (type TXT) records in that you have to publish (add) to your domain’s DNS configuration. These records use the formats shown in the following table.

Name Record Type Value
subdomain.example.com MX 10 feedback-smtp.region.amazonses.com
subdomain.example.com TXT v=spf1 include:amazonses.com ~all

Step 2

Produce an SVG Tiny PS version of your official logo

In order to display your logo in the email it must conform to the specifications of the BIMI requirements. To meet these requirements the logo must be a Scalable Vector Graphics (SVG) image and must meet the Tiny PS Specification. Once your image meets this requirement you can move on to the next step.

Note: bimigroup.org outlines this process and includes references to software to assist with this process.

Step 3

Upload your image to an S3 bucket

  1. Sign in to the AWS Management Console and open the Amazon S3 console at https://console.aws.amazon.com/s3/
  2. In the Buckets list, choose the name of the bucket that you want to upload your folders or files to.
  3. Choose Upload.
  4. In the Upload window, do one of the following:
    • Drag and drop files and folders to the Upload window.
    • Choose Add file choose your SVG image to upload, and choose Open.

To configure additional object properties

  1. To change access control list permissions, choose Permissions.
  2. Under Access control list (ACL), edit the permissions.
    • You need to grant read access to your objects to the public (everyone in the world) for the SVG image you are uploading. However, we recommend not changing the default setting for your bucket to public read access.
  1. To configure other additional properties, choose Properties.
  2. To upload your objects, choose Upload.

Note: Amazon S3 uploads your object. When the upload completes, you can see a success message on the Upload: status page.

  1. Choose Exit.

Step 4

Publish a BIMI record for your domain

  1. Sign in to the AWS Management Console and open the Route 53 console at https://console.aws.amazon.com/route53/
  2. In the navigation pane, choose Hosted zones.
  3. On the Hosted zones page, choose the name of the hosted zone that you want to create records in.
  4. Choose and define the applicable routing policy and the following values with the understanding the URLs must be HTTPS:
Name Record Type Value
default._bimi.example.com TXT v=BIMI1; l=[SVG URL]; a=[PEM URL]
  1. Choose Create records.

Note: the a= tag is currently optional and will not be used in this example.

You can validate your BIMI record with a tool like the BIMI Inspector.

Conclusion

All of the steps to set up your SES account and your domain are now complete. The final component in this process is to have regular sending patterns to the mailbox providers that support BIMI logo placement. Your domain should have a regular delivery cadence and needs to have a good reputation with the mailbox providers you are sending mail. BIMI logo placement may take time to populate to mailbox providers where you don’t have an established reputation or sending cadence. The time spent implementing BIMI is well worth it as it will strengthen your sender reputation and create a better and more trusted customer experience for your end recipients.
