Email Trigger

Starts a Workflow instance when an email is delivered to a dedicated email address. Attributes of each email, including attachments, subject, sender, and more, are available as fields in each instance started.

The subject line of the message sent to the Email trigger will be used as the name of the triggered instance.

Use Case

Like Web form triggers, this trigger lets non-Catalytic users initiate a Workflow instance with an email. Another common use is to parse files, since files can be passed to Catalytic as an attachment through sent emails.

How to configure this trigger

You can add new triggers or configure any existing triggers on a Workflow鈥檚 edit screen. Triggers are configured for each Workflow.

Each email trigger is set up with a unique email address with the format {your-custom-address}@{your Catalytic team}.pushbot.com, such as submitaclaim@teamalpha.pushbot.com Change the address at any time from the triggers page of your Workflow.

Please refrain from using the words when naming your email trigger: -admin@, autoreply.*@, -autoresponder@, autoresponder@, -bounce@, bounce-@, bounce@, -bounces@, -confirm@, daemon@, -errors@, exim@, fetchmail@, httpd@, info@, lighttpd@, listmaster@, listserv@, mailer_daemon@, mailer-daemon@, mailer@, mailman@, mailmaster@, majordom@, majordomo@, nagios@, no-reply@, nobody@, noreply.*@, -outgoing@, -owner@, owner-, postmaster@, -relay@, reminder@, -request@, root@, sales@, server@, squid@, support@, webmaster@, www-data@, www@

What will this output?

Every incoming email starts an instance of a Workflow. Attributes of each email, including attachments, subject, or sender are available as fields within the Workflow.

How to reference a single attachment when an incoming email has multiple attachments

This trigger automatically outputs a table of trigger attachments whenever an incoming email includes attachments. If there is more than 1 file, use the following steps to reference a specific file.

To reference the files in that table, you can add and configure two actions in the Workflow: Tables: Look up data in a column and Text: Find text next to other text.

The following steps show how to add an action to look through each row of the table for a matching row, then a second action to look up the file ID in that row.

  1. To search the trigger attachments table, add a Tables: Look up data in a column action, and configure the action in as follows to search the Extension column for pdf.
    1. Data table: {{trigger-attachments}}
    2. Lookup column name: Extension
    3. Search term: pdf
    4. Output field prefix: extract-pdf
  2. Second, we use the Text: Find text next to other text action to extract the file ID from the data we looked up from the first step.
    1. Text to search: {{extract-pdf--file}}
    2. Start type: after-text
    3. Start value: https://[insertteamnamehere].pushbot.com/v1/teams/[insertteamnamehere]/files/
    4. End type: before-text
    5. End value: /download
    6. Output field prefix: pdf-file-id

Then you can use the output from Step 2, {{pdf-file-id--first-match}}, to reference the pdf file.

My inbound emails are not always triggering a new instance

This may happen if your inbound emails are especially long, such as threads with multiple nested replies and forwards. Because the email body is turned into a single field, it may hit the 128kb field size system limit.

How do I view all attachments included in an email

This action outputs a table in the Trigger attachments output field with a list of every attachment included in the email. It includes the file download URL, name, type, extension, size in bytes, and location of every file.
