Tools for constructing and sending emails

Project description


Writing a web application? Want to send some emails from it? Mailtools can help!

  • Simple API for sending plain text messages, HTML and messages with attachments.
  • ThreadedMailer sends emails in the background and returns control to your application immediately, even when talking to slow remote servers.
  • Temporary sending failures are automatically retried.
  • Running your application in test mode? The RedirectMessages wrapper routes emails to a test address and not to live email addresses.


Creating a simple SMTP mailer:

from mailtools import SMTPMailer
mailer = SMTPMailer('')

This mailer will block until messages are sent and won’t retry failures. Use ThreadedMailer to fix this:

mailer = ThreadedMailer(SMTPMailer(''))

A mailer with TLS/STARTTLS support:

mailer = SMTPMailer('', 465, transport_args={'security': 'TLS'})
mailer = SMTPMailer('', transport_args={'security': 'STARTTLS'})

Sending a plain text message:

message = 'This is a plain text message'

Sending an HTML message:

message = '<html><body>Look! HTML!</body></html>'

Adding attachments:

message = 'index.rst is attached to this message'
