What is an easy way to test Amazon SES?

The Amazon SES sandbox is a restricted environment where new users can experiment with Amazon SES. In the sandbox, you can only send emails to verified identities (email addresses or domains that you own). This setup helps users test and understand the capabilities of Amazon SES while maintaining some limits on volume and sending rates.

How can I track my Amazon SES usage?

You can monitor your Amazon SES usage through the AWS Management Console or the Amazon SES API. The AWS Management Console provides a dashboard where you can view your send quota and other metrics related to your email sending. The Amazon SES API, on the other hand, allows you to retrieve detailed usage data programmatically. You can also set up Amazon CloudWatch alarms to receive notifications when you approach certain usage thresholds.

Can I start sending large email volumes right away?

Initially, you can only send emails to verified recipients in the Amazon SES sandbox. To send emails to non-verified recipients or in larger volumes, you need to submit a Sending Limit Increase request through the AWS Support Center. Amazon SES sets limits to ensure the responsible use of the service.

Can I send emails from any email address?

No, you can only send emails from addresses or domains that you own. To send from a particular address or domain, you must verify it within Amazon SES. You are allowed to verify up to 10,000 email addresses and domains in each AWS Region.

Is there a limit on the size of emails Amazon SES can deliver?

Amazon SES can handle email messages up to 40MB in size, including any attachments and images. However, for messages larger than 10MB, there might be bandwidth throttling based on your sending rate. For example, sending a 40MB message might be limited to 1 message per second or two 20MB messages per second, depending on the situation.

Are there any limits on how many emails I can send?

Yes, every Amazon SES account has sending limits, including a sending quota and a maximum send rate. These limits are based on the number of recipients rather than individual messages. You can check your specific sending limits in the Amazon SES console. Amazon SES may pause your email sending if it detects poor quality, such as high bounce or complaint rates, or unsolicited content.

Does Amazon SES support the Sender Policy Framework (SPF)?

Yes, Amazon SES supports SPF. Whether you need to publish an SPF record depends on how you use Amazon SES to send emails. By default, Amazon SES sends emails from a MAIL FROM domain owned by Amazon Web Services. However, if you want to comply with DMARC using SPF, you'll need to set up Amazon SES to use your MAIL FROM domain and publish an SPF record.

Does Amazon SES support Domain Keys Identified Mail (DKIM)?

Yes, Amazon SES supports DKIM. You can enable and configure Easy DKIM in Amazon SES to sign outgoing messages using DKIM on your behalf. You can also sign your email manually. However, there are specific DKIM headers that you should not sign for optimal deliverability.

Can emails from Amazon SES comply with DMARC?

Yes, you can configure emails sent from Amazon SES to comply with DMARC (Domain-based Message Authentication, Reporting, and Conformance). To achieve this, you need to verify the domain you're sending email from, set up necessary DNS records like SPF and DKIM, and publish a DMARC policy in your DNS records.

What is the difference between a dedicated IP address (standard) and (managed)?

Both options involve dedicated IP addresses for managing your sending reputation. The key difference is that "Dedicated IP Addresses (standard)" requires manual setup and management of IP addresses, while "Dedicated IP Addresses (managed)" is designed to reduce the need for manual monitoring and scaling of IP pools. The managed option helps with warmup status modeling and preventing overspending, which can affect email deliverability.

Can I specify a dedicated IP address when I send certain types of emails?

If you have leased multiple dedicated IP addresses for your Amazon SES account, you can use the dedicated IP pools feature. This allows you to create groups (pools) of dedicated IP addresses and associate each pool with a configuration set. When you send emails using that configuration set, they will be sent only from the IP addresses in the associated pool.

Can I test Amazon SES responses without sending emails to real recipients?

Yes, you can use the Amazon SES mailbox simulator to test your email-sending setup without actually sending emails to real recipients. This helps you evaluate your sending rate and handling of events like bounces and complaints. Messages sent to the mailbox simulator don't affect your bounce and complaint metrics or your daily sending quota. However, you are charged for using this service.

Does Amazon SES provide an SMTP endpoint?

Yes, Amazon SES provides an SMTP interface that allows seamless integration with applications capable of sending emails via SMTP.

Factors such as ISP decisions, incorrect recipient email addresses, or the recipient's choice to reject or drop emails can affect email delivery.

How long does it take for emails sent using Amazon SES to arrive in recipients' inboxes?

Amazon SES attempts to deliver emails within seconds of each request. However, the exact delivery time is uncertain due to various factors and the nature of the internet. If a delivery error occurs, Amazon SES may attempt redelivery or provide a hard bounce notification.

Can my email deliverability be affected by bounces or complaints caused by other Amazon SES users?

Typically, your email-sending ability remains unaffected by bounces or complaints generated by other Amazon SES users. An exception is when a recipient's email address results in a hard bounce, as Amazon SES adds it to a global suppression list. Emails sent to addresses on this list count toward your sending quota and bounce rate, and the address remains suppressed for up to 14 days.

Can I encrypt the email messages that I receive?

Amazon SES integrates with AWS Key Management Service (KMS) to encrypt the emails it writes to your Amazon S3 bucket. The encryption is performed on the client side, and you need to decrypt the content on your side after retrieving the email from Amazon S3.

Does Amazon SES send an email over an encrypted connection using Transport Layer Security (TLS)?

Amazon SES supports TLS 1.2, TLS 1.1, and TLS 1.0 for TLS connections. By default, Amazon SES uses opportunistic TLS, which means it attempts to make a secure connection to the receiving mail server. If a secure connection can't be established, the message is sent unencrypted.

How does Amazon SES ensure that incoming mail is free of spam and viruses?

Amazon SES employs spam and virus protection measures, including block lists to prevent known spammers and virus scans for emails with attachments. Amazon SES makes its spam detection verdicts, virus scan results, DKIM, and SPF check results available to help you assess the trustworthiness of each message.

How is Amazon SES different from Amazon SNS?
