Email Subscriber

The Email subscriber receives messages from topics and delivers emails via the SMTP protocol.

Note  Email servers may have maximum connection limitations. When an email subscriber sends multiple emails to the same server in quick succession, this limitation may cause emails to be dropped. To fix this issue, adjust the MAX_WORKER_THREADS parameter in the email.properties file, located in <FMEFlowDir>/Server/config/subscribers, to a value at or below the corresponding value of the email server. For example, if the email server's connection limit is 20, lower MAX_WORKER_THREADS from 100 (default) to 20.

In the FME Flow Web User Interface, select Notifications > Subscriptions, and click New.

Keywords

Using the following keywords, you can override the settings specified in the subscriber configuration:

  • email_to
  • email_cc
  • email_bcc
  • email_from
  • email_subject
  • email_replyto
  • email_attachment
  • subscriber_content: Overrides the Email Template setting.

"email_replyto": "",
