Service quotas in Amazon SES
The following sections list and describe the quotas that apply to Amazon SES resources and operations. Some quotas can be increased, while others can't. To determine whether you can request an increase for a quota, refer to the Adjustable column.
Note
SES quotas are for each AWS Region that you use in your AWS account.
Email sending quotas
The following quotas apply to sending email through SES.
Sending quotas
Quotas are based on the number of recipients, rather than on the number of messages.
| Resource | Default Quota | Adjustable |
|---|---|---|
| Number of emails that can be sent per 24-hour period |
If your account is in the sandbox, you can send up to 200 emails per 24-hour period. If your account is out of the sandbox, this number varies based on your specific use case. |
|
| Number of emails that can be sent per second (sending rate) |
If your account is in the sandbox, you can send 1 email per second. If your account is out of the sandbox, this rate varies based on your specific use case. |
Message quotas
| Resource | Default Quota | Adjustable |
|---|---|---|
|
Using the SES v1 API - Maximum message size (including attachments) |
10 MB per message (after base64 encoding). |
No (For workloads with message sizes in excess of 10MB, consider migrating to the SES v2 API.) |
|
Using the SES v2 API or SMTP - Maximum message size (including attachments) |
40 MB per message (after base64 encoding). |
No |
Note
Messages larger than 10MB are subject to bandwidth throttling, and depending on your sending rate, you may be throttled to as low as 40MB/s. For example, you could send a 40MB message at the rate of 1 message per second, or two 20MB messages per second.
