A Go web application to generate email signatures and host uploaded images with S3.
GoMailMark allows users to enter information about them, uploads given images to S3, and generates an HTML signature using Templ.
- Generate email signatures based on a Templ.
- Upload image files to S3.
- 12-factor configuration.
- Easy deployment with Docker.
To use GoMailMark you'll need to create an S3-compatible bucket to which images will be uploaded. MinIO is supported.
GoMailMark runs a Go server and requires some configuration beforehand via environment variables pre-fixed with MAIL_MARK_ or a config.json/config.yml in the current working directory.
To start the server run go run main.go and head to localhost:8000. The default port can be configured via the configuration key server.port.
If you want to programmatically use GoMailMark, you can send HTTP POST requests to / with a multi-part form data containing the following fields:
name- Your name.email- Your email address.email- Your email address.phone- Your phone number.linkedin- Your LinkedIn URL.picture- A file containing an image to be uploaded to S3.
GoMailMark is designed to be forked and updated to your needs. The fields in the signature as well as its overall design can be easily modified. GoMailMark simply provides a web server and the S3 upload functionality for convenience.
GoMailMark can be configured using various configuration formats, for example your config.yml could look like this:
s3:
host: localhost:9005
accessKeyId: minioadmin
secretAccessKey: minioadmin
bucket: email-signature-generator
signature:
company:
name: Your Company Name
url: https://example.com
address:
street: Street
number: Nr
zip: Zip
