You can use the following services to send email notifications to your users:

The primary reasons to use a custom SMTP or Amazon SES service are:

  • You can manage your own SPF record and handle email bounces yourself
  • You can access email statistics

Proper email service configuration helps prevent your notifications from being marked as spam.

Click X recipients to see details and the affected email addresses.

Configure Custom Amazon SES Email Service

If you have an Amazon AWS account, you can use your specific Amazon SES. This service may be useful when you need to send many email messages simultaneously, view email sending statistics, etc.

SES-configured AWS account needs to be added to the Management Console even if you do not use Amazon S3 as your backup storage provider.

To estimate your expenses using Amazon SES, refer to the Amazon SES pricing chapter at aws.amazon.com

Note that once you selected the Amazon SES email service, in order to get back to the MSP360 email service usage, you need to address to MSP360 technical support team for assistance

To use the Amazon SES email service, proceed as follows:

  1. Perform steps 1-2 described in the Configure Email Service paragraph.
  2. Select Amazon SES.

  1. Select SES configured AWS account that was added to Management Console.

  2. Proceed with the steps provided for the Amazon SES email service:

  • Verify your email. Click Verify Email, then wait until your email address is verified

    • You can only send mail to verified email addresses and domains, or the Amazon SES mailbox simulator
    • You can only send mail from verified email addresses and domains
    • You can send a maximum of 200 messages per 24-hour period
    • You can send a maximum of 1 message per second

To request that your account be removed from the Amazon SES sandbox using the AWS Management Console, proceed with the instructions in the Moving out of the Amazon SES sandbox chapter at docs.aws.amazon.com
