Composes an email message and immediately queues it for sending.
This operation is more flexible than the
API operation. When you use the
operation, you can specify the headers of the message as well as its content. This flexibility is useful, for example, when you want to send a multipart MIME email (such a message that contains both a text and an HTML version). You can also use this operation to send messages that include attachments.
operation has the following requirements:
- You can only send email from verified email addresses or domains. If you try to send email from an address that isn't verified, the operation results in an "Email address not verified" error.
- If your account is still in the Amazon SES sandbox, you can only send email to other verified addresses in your account, or to addresses that are associated with the Amazon SES mailbox simulator.
- The maximum message size, including attachments, is 10 MB.
- Each message has to include at least one recipient address. A recipient address includes any address on the To:, CC:, or BCC: lines.
- If you send a single message to more than one recipient address, and one of the recipient addresses isn't in a valid format (that is, it's not in the format UserName@[SubDomain.]Domain.TopLevelDomain), Amazon SES rejects the entire message, even if the other addresses are valid.
- Each message can include up to 50 recipient addresses across the To:, CC:, or BCC: lines. If you need to send a single message to more than 50 recipients, you have to split the list of recipient addresses into groups of less than 50 recipients, and send separate messages to each group.
- Amazon SES allows you to specify 8-bit Content-Transfer-Encoding for MIME message parts. However, if Amazon SES has to modify the contents of your message (for example, if you use open and click tracking), 8-bit content isn't preserved. For this reason, we highly recommend that you encode all content that isn't 7-bit ASCII. For more information, see MIME Encoding in the Amazon SES Developer Guide.
Additionally, keep the following considerations in mind when using the
- Although you can customize the message headers when using the
SendRawEmail operation, Amazon SES will automatically apply its own
Date headers; if you passed these headers when creating the message, they will be overwritten by the values that Amazon SES provides.
- If you are using sending authorization to send on behalf of another user,
SendRawEmail enables you to specify the cross-account identity for the email's Source, From, and Return-Path parameters in one of two ways: you can pass optional parameters
ReturnPathArn to the API, or you can include the following X-headers in the header of your raw email:
Don't include these X-headers in the DKIM signature. Amazon SES removes these before it sends the email. If you only specify the
SourceIdentityArn parameter, Amazon SES sets the From and Return-Path addresses to the same identity that you specified.
For more information about sending authorization, see the Using Sending Authorization with Amazon SES in the Amazon SES Developer Guide.
- For every message that you send, the total number of recipients (including each recipient in the To:, CC: and BCC: fields) is counted against the maximum number of emails you can send in a 24-hour period (your sending quota). For more information about sending quotas in Amazon SES, see Managing Your Amazon SES Sending Limits in the Amazon SES Developer Guide.
