Configuring Email Clients to Send Through Amazon SES

After you have obtained your SMTP credentials, you can begin sending email through Amazon SES. You can use any email client application, provided that it can communicate via SMTP and connect to an SMTP endpoint using Transport Layer Security (TLS). Most email clients can send email using an SMTP server.

To configure your email client, you must provide the Amazon SES SMTP interface hostname and port number (see Connecting to the Amazon SES SMTP Endpoint), along with your SMTP user name and password (see Obtaining Your Amazon SES SMTP Credentials).

The following procedure shows how to configure one such client, Microsoft Outlook 2010, so that it can send email through the Amazon SES SMTP interface. If you are using a different email client, follow the instructions provided by the client vendor, and use the settings described in the following procedure.

To configure Microsoft Outlook 2010 for sending via Amazon SES

  1. On the File menu, click the Info link on the side of the page to reveal the Account Information page.

  2. Click the Add Account button.

  3. On the Auto Account Setup page, select the Manually configure server settings or additional server types option, and then click Next.

  4. On the Choose Service window, choose Internet E-Mail and then click Next.

  5. On the Internet E-mail settings form, fill in the following fields:

    1. Your Name—Your real name.

    2. E-Mail Address—The address from which emails will be sent. You will need to verify this email address or its domain before you can send from it. For more information about verifying email addresses and domains, see Verifying Email Addresses and Domains in Amazon SES.

    3. Account Type—POP3

    4. Incoming mail server—type the word none. (Even though Amazon SES does not receive email, Outlook still requires that you fill in this field.)

    5. Outgoing mail server (SMTP)—See Connecting to the Amazon SES SMTP Endpoint for a list of Amazon SES SMTP endpoints. For example, if you want to use the Amazon SES endpoint in the US West (Oregon) region, the outgoing mail server would be

    6. User Name—type the word none. (You will configure your credentials later in this procedure.)

    Microsoft Outlook 2010 configuration
  6. Click More Settings.

  7. In the Internet E-mail Settings dialog box, click the Outgoing Server tab and fill in the following fields:

    1. My outgoing server (SMTP) requires authentication—check this box.

    2. Log on using—choose this option.

    3. User Name—enter your SMTP user name.


      Use your SMTP user name, not your AWS access key ID. Your SMTP credentials and your AWS credentials are not the same. For information about how to obtain your SMTP credentials, see Obtaining Your Amazon SES SMTP Credentials.

    4. Password—enter your SMTP password.


      Use your SMTP password, not your AWS secret access key. Your SMTP credentials and your AWS credentials are not the same. For information about how to obtain your SMTP credentials, see Obtaining Your Amazon SES SMTP Credentials.

    5. Remember Password—check this box.

  8. In the Internet E-mail Settings dialog box, click the Advanced tab and fill in the following fields:

    1. Outgoing server (SMTP)—25, 587, or 2587 (to connect using STARTTLS), or 465 or 2465 (to connect using TLS Wrapper).

    2. Use the following type of encrypted connection—TLS (to connect using STARTTLS) or SSL (to connect using TLS Wrapper).

    Settings for TLS Wrapper are shown below.

  9. Click OK.

  10. On the Internet E-mail Settings page of the wizard, click Test Account Settings. This lets you test your setup by having Outlook send an email through Amazon SES.


    Because you did not specify an incoming mail server (Amazon SES is only used for outgoing email), the Log onto incoming mail server test is expected to fail. The Send test e-mail test should pass.

  11. If the test message that Outlook sends through Amazon SES arrives successfully, clear the Test Account Settings by clicking the Next button checkbox (because the test will fail without setting up incoming email) and then click Next.

  12. Click Finish.

  13. Amazon SES is for mail sending only. To prevent Microsoft Outlook from attempting to receive messages through the account you just set up, you need to disable mail retrieval for the account by using the following steps.

    1. In Microsoft Outlook, click the Send/Receive tab.

    2. On the Send/Receive tab, click Send/Receive Groups, and then click Define Send/Receive Groups.

    3. In the Send/Receive Groups dialog box, click Edit.

    4. In the left panel of the Send/Receive Settings - All Accounts dialog box, click the account you just created for sending mail through Amazon SES.

    5. Under Account Options, clear Receive mail items.

    6. Click OK, and then click Close.
