You can use your own SMTP (or even gmail) instead of Sendgrid.

Add your SMTP details to Cloud Composer as follows:

  1. Configure email and smtp settings by overriding the email backend:
    https://cloud.google.com/composer/docs/composer-2/configure-email#configure_third-party_smtp_services
    Because I was using SSL, I had to set:
    port=465
    smtp_ssl=True
    smtp_starttls=False
  1. Add your smtp password to GCP Secret Manager:
    https://cloud.google.com/composer/docs/composer-2/configure-email#smtp_password
    Additional note: don't forget to give your Cloud Composer service account access to the password by give it the role Secret Manager Secret Accessor in IAM.

Or alternatively you can use Gmail.
I didn't try this myself, but I think it's good to know that this is also possible.
Here's an example of someone describing the process: https://helptechcommunity.wordpress.com/2020/04/04/airflow-email-configuration/

Because sending email or opening SMTP email relays can be a dangerous or prohibited Cloud behavior, we recommend you use Sendgrid to send email from Composer environments. The Composer environment setup directions contain a section specifically on how to setup Sendgrid with Cloud Composer.
