Output the contents of a log file to Home Assistant SMTP

Configuration
1

Hi

I’m currently logging who arms/disarms the alarm at out office to a file /config/access_log
I would like to be able to send this file using HA’s SMTP integration, but you’re limited to images, audio and video.

Is there a way to, instead of trying to send the file, cat the output of the file into the message contents of the email?

Currently, the automation runs at 6pm every night…

alias: Alarm Log Emailer
description: ""
trigger:
  - platform: time
    at: "18:00:00"
condition: []
action:
  - service: notify.alarm_log_emailer
    data:
      data:
        file: /config/access_log
      message: This is an email
      title: Alarm Log data
mode: single

But I’m unsure of how to populate the message section with the contents of /config/access_log

Thanks
