Goeland excels at creating beautiful emails from RSS feeds, tailored for daily or weekly digest.
It includes a number of filters (see below) that can transform the RSS content along the way. It can also consume other sources, such as Imgur tags.

Goeland has a size-fits-all default template that works well with mobile, tablet, desktop and webmail clients.
Goeland can extract full text from most article sources, enabling a ready to consume email.
Goeland is used in production with many email clients, and has sent over thousands of emails. It is considered stable.
Grab the latest binary release from the release page. Binaries are available for the following platforms:
Just put it in a folder where you have write permissions and run it first with :
goeland runIf you are interested for another platform to be supported, please open a PR or submit a feature request.
On first run, if it doesn't exist yet, goeland will create a config.toml with the default values. You need to adjust the [email] section with your SMTP server details.
The config values can also be set with environment variables (e.g. GOELAND_EMAIL_PASSWORD_FILE=/path/to/pass).
Afterwards, fill the [sources] and [pipes] sections.
Source are identified by their name after the [source.] field:
[sources.hackernews]
type = "feed"
url = "https://hnrss.org/newest"
filters = ["all", "today"]You can then use 'hackernews' in the following pipes.
The different source types are:
"feed": RSS, Atom or JSON feed (all supported formats can be found here). Fill in the url field."imgur": Return most recent results for a tag. Fill in the the tag field."merge": Will merge two or more sources together. Fill in the sources field with a list of sources: sources = ["source1", "source2"]. Especially useful to merge different sources on the same topic. Don't forget to digest or combine it later.One powerful aspect of goeland is filtering. Instead of sending the content of the RSS directly to the email system, it can transform it in a number of ways in order to make it easier to read, process, etc.
Any number of filters can be defined, the order is important. For example, the following:
filters = ["unseen", "retrieve", "digest"]Will first keep only previously unseen entries, then make it nicer with the retrieve filter, and, at last, will put them all together with digest. This will create only one email with a SourceTitle as the title of the RSS feed.
Filters can have options. For example, to get the 3 newest post, you would do:
filters = ["first(3)"]The available filters are as follows:
goeland.db file. Use the purge command to remove seen entries[replace.myreplace]
from="A string"
to="Another string"in your config file.
retrieve(div.content) to get the full excerpts of Next INpact's LeBrieflanguage(en,de)toc(title) to use the Title as a linklimitwords(32)After defining some sources, you can send them to a pipe. One source can be sent to multiple pipes, but a pipe can only have one source. If you need to combine sources together, use the above special merge.
A pipe has the following structure:
[pipes.hackernews]
source = "hackernews"
destination = "email"
email_to = "example@example.com"
email_from = "HackerNews <goeland@example.com>"
email_title = "{{.EntryTitle}}"
template = "/path/to/template.html" # optionalYou can use EntryTitle, SourceTitle and SourceName in the email template. SourceTitle is the title of the RSS feed.
For debugging purposes, or in order to pipe to other systems, you can set the destination to terminal.
In the email section you need to specify your outgoing mail server. You can specify both encryption and allow-insecure to connect to self-hosted servers. You can also specify authentication to select the appropriate option for your server (the options available are "none", "plain", "login" and "crammd5"; if unspecified it defaults to "plain"; see go-simple-mail's documentation for details).
[email]
host = "smtp.example.com"
port = 25
username = "default"
password = "p4ssw0rd"
# password_file = /run/password/goeland_smtp_pass
encryption = "tls"
allow-insecure = false
authentication = "plain"
#Email customization
include-header = true
include-footer = true
#footer = Your custom footer
#logo = internal:goeland.png
#template = /path/to/template.htmlYou can create your own template, see relevant documentation.
The pipe template takes precedence over the main template defined in the [email] section.
This will bring you 6 puppies to your inbox.
loglevel = "info"
dry-run = false
[email]
host = "smtp.sendgrid.net"
port = 587
username = "apikey"
password = "<sendgridapikey>"
[sources]
[sources.insta]
url = "https://rssbridge.example.com/?action=display&bridge=Instagram&context=Hashtag&h=puppy&media_type=picture&direct_links=on&format=MRss"
type = "feed"
filters = ["random(3)"]
[sources.imgur]
type = "imgur"
tag = "puppy"
filters = ["random(3)"]
[sources.puppies]
type = "merge"
sources = ["insta", "imgur"]
filters = ["combine"]
[pipes]
[pipes.puppies]
source = "puppies"
destination = "email"
email_to = ["puppylover@example.com"]
email_from = "DailyPuppy <goeland@example.com>"This will give you the latest article on a specific subreddit:
loglevel = "none"
dry-run = false
database = "goeland.db"
[email]
host = "example.com"
port = 25
username = "username"
password = "password"
[sources]
[sources.reddit]
url = "https://www.reddit.com/r/selfhosted/top.rss"
type = "feed"
filters = ["unseen", "includelink", "digest"]
[pipes.reddit]
source = "reddit"
destination = "email"
email_to = ["example@example.com"]
email_from = "Reddit <reddit@example.com>"It is possible to send an email to multiple addresses, just put them in a list:
[pipes.reddit]
source = "reddit"
destination = "email"
email_to = ["bob@example.com", "alice@gmail.com", "charles@yahoo.com"]
email_from = "Reddit <reddit@example.com>"See also the examples/ folder.
Feel free to open issues or PR for bugs and suggestions for more filters and source types.
If you encounter a problematic feed, please open an issue with the content of the feed attached.
