DETA programs have their own unique email address. They can currently send plain text emails (soon they'll also be able to receive email).

To use DETA Email, just import the email helper from deta.lib:

from deta.lib import email

Then use the command below.

email(to, subject, message) to send an email.

  • to an email address (str) or a list of recipients.
  • subject the subject line (str).
  • message the email's body (str).
example code
from deta.lib import app, email

email("", "Happy Birthday!", "Dear Ludwig,...")
email(["", ""], "January Update", "Hello team, ..")
