A simple webapp to manage your email campaigns and subscribers. SMTP server agnostic.

List management:

• Hosted newletter homepage
• Embed-able newsletter signup form
• Ajax friendly API to signup subscribers
• Confirmation via email for each new subscribers
• Import subscribers from Mailchimp CSV
• import subscribers from copy/pasting emails and names
• Unsubscribe/delete subscribers

Email management:

• Custom Reply-To: address
• Live HTML preview while writing or pasting the email content
• HTML email preview before sending
• Send test email before sending to the list
• Auto-CSS inlining for greated email client support (keeping responsive layout and media queries)
• Auto-minifying of HTML email to prevent a truncated message (Gmail imposes a length limit to emails)
• Auto-generation of text email from the HTML (keeping the links target and heading hierarchies)
• Auto-generation/inclusion of an unsubscribe link for each email sent

Things Minimail will not provide for now

• Drag and drop HTML email builder (you’ll need to write or copy/paste your HTML email)

• Python 3.5
• Django 1.10
• Twitter Bootstrap 3.3.7 (moving to version 4 once stable)

For Python libraries in use, see requirements.txt.

Minimail can work with AWS SES, Mailgun, Postmark, Sendgrid or any other email sending service. The only requisite is to have them provide you with an SMTP server. Once with your SMTP server credentials in hand, here are the steps to make it work with Minimail:

1. Install Postfix locally on your server
2. Configure Postfix as a relay to your SMTP server.

Example setting up Postfix as an SMTP relay with AWS SES:

The configuration file to change is (likely to be): /etc/postfix/main.cf

relayhost = [email-smtp.us-east-1.amazonaws.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_use_tls = yes
smtp_tls_security_level = encrypt
smtp_tls_note_starttls_offer = yes
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt

Notes:

• Here we are using email-smtp.us-east-1.amazonaws.com as the SMTP server URL, but yours might be different.
• Don't use the port 25 to connect to your SMTP from an AWS EC2 instance. There is a throttling in place on EC2 instance on port 25.
• For a complete guide, see [AWS official documentation on Integrating Amazon SES with Postfix
• The advantage of using SMTP over an HTTP based API is delegating the sending queue to mature and stable software (Postfix in this case) to handle bounces due to sending quota and ratio. SMTP has more round trips per email to send than an HTTP API, but the first SMTP server being on localhost this overhead is insignificant. Using SMTP also makes Minimail email backend agnostic as the SMTP protocol play the role of a facade pattern.

1. virtualenv --python=python3.5 . && source bin/activate
2. pip install -r requirements.txt
3. ./manage.py makemigrations && ./manage.py migrate
4. ./manage.py runserver

1. export MINIMAIL_ENV=prod
2. virtualenv --python=python3.5 . && source bin/activate
3. pip install -r requirements.txt
4. ./manage.py makemigrations && ./manage.py migrate
5. Start the app with gunicorn: ./server_conf/start_stop_django_app.sh
6. Link the app nginx configuration file to nginx default conf folder: sudo ln -s /path/to/repo/server_conf/minimail.nginx.conf /path/to/nginx/main/conf/minimail.nginx.conf
7. Test and reload nginx: sudo nginx -t && nginx -s reload

1. create the service description in /etc/systemd/system/minimail.service

[Unit]
Description=app
After=network.target

[Service]
Type=simple
User=root
Group=root
WorkingDirectory=<your app directory>/minimail
ExecStart=<your app directory>/minimail/server_conf/start.sh

[Install]
WantedBy=multi-user.target

2. sudo systemctl daemon-reload
3. sudo systemctl start minimail
4. sudo systemctl enable minimail to launch minimail on startup

Check for code syntax with pylint -r no -f colorized minimail. Add this command in .git/hooks/pre-commit to auto-check as you commit.

We use Twitter Bootstrap, customized with system fonts.
