Subscribe: a web interface for subscribing to mailing lists

If you use mailgun.com, mailjet.com or sendinblue.com to manage contacts/mailing lists but do not want your users to share data with an third-party sign-up form, Subscribe can help.

If you have several mailing lists (possibly handled by several different providers among mailgun/mailjet/sendinblue) and want to list various list subscription options on a single page, Subscribe can help.

Features

• Support mailgun.com, mailjet.com or sendinblue.com mailing lists
• Include/exclude mailing lists one by one or with regular expressions
• Let the admin of a list receive an email every x subscriptions
• Customize the HTML header and footer of the web interface
• Use your own stylesheet (as long as it’s based on bulma.io)
• UI and transactional emails in english and french

Configure

Configuring subscribe is done in two steps: you first need to set environment variables for global options (including the default credentials for transactional emails), then to edit the config.edn file for mailing lists.

1. Set up environment variables

Application variables:

export SUBSCRIBE_PORT=3000
export SUBSCRIBE_BASEURL="http://yourdomain.com"

Email credentials:

export SUBSCRIBE_SMTP_LOGIN="postmaster@xxx"
export SUBSCRIBE_SMTP_PASSWORD="your-password"
export SUBSCRIBE_SMTP_HOST="smtp.mailgun.org"
export SUBSCRIBE_SMTP_PORT=587

Backend-specific variables:

# To handle mailgun.com mailing lists:
export MAILGUN_API_KEY="your-key"

# To handle sendinblue.com mailing lists:
export SENDINBLUE_API_KEY="your-key"

# To handle mailjet.com mailing lists:
export MAILJET_API_KEY="your-key"
export MAILJET_API_SECRET="your-password"

Note that only mailjet.com requires both an API key and password, mailgun.com and sendinblue.com only requires an API key.

2. Define options in config.edn

Copy config_example.edn to config.edn and edit it.

The mandatory configuration options are :admin-email and :backends.

Test

~$ git clone https://github.com/bzg/subscribe
~$ cd subscribe/
... [Set up your environment variables and config.edn]
~$ clj -M:test

Run

With clj -M:run

... [Set up environment variables]
~$ git clone https://github.com/bzg/subscribe
~$ cd subscribe/
... [Edit config.edn to configure mailing lists]
~$ clj -M:run

Then go to http://localhost:3000 or to your custom base URL.

With java -jar

... [Set up environment variables]
~$ git clone https://github.com/bzg/subscribe
~$ cd subscribe/
... [Edit config.edn to configure mailing lists]
~$ clj -M:jar
~$ java -jar target/subscribe.jar

With docker

Assuming your environments variables are stored in ~/.subscribe_envs and you want to expose the 3000 port:

~$ git clone https://github.com/bzg/subscribe
~$ cd subscribe/
... [Edit config.edn to configure mailing lists]
~$ docker build -t subscribe .
~$ docker run -it -p 3000:3000 --env-file=~/.subscribe_envs subscribe

Then go to http://localhost:3000.
