Customize subject format for standard emails


(Arpit Jalan) #1

So you want to customize subject format for standard emails? Great, let’s get started!

The subject for standard emails can be customized from: Admin / Settings / Email / email subject

Available formatting options are:

%{optional_re}[%{site_name}] %{optional_pm}%{optional_cat}%{topic_title}

  • %{optional_re} → Re: (applicable if the post is a Reply)

  • %{site_name} → Community Title

  • %{optional_pm} → [PM] (applicable if the post is a Personal Message)

  • %{optional_cat} → [category] / [category/subcategory] {not applicable for uncategorized topics and PM)

  • %{topic_title} → Topic title

Complied subject for typical email notification:

[Community Title] [category] Topic title

Please note that a trailing whitespace will automatically be appended to %{optional_re}, %{optional_pm} and %{optional_cat}.

For Example, let’s consider this post:

The email subject formatting for Reply notification of above topic will be:

  • %{optional_re} → Re:

  • %{site_name} → Discourse Meta

  • %{optional_pm} → (Not Applicable)

  • %{optional_cat} → [howto]

  • %{topic_title} → How to update to Discourse 1.0?

Complied subject for the above topic will be:

Re: [Discourse Meta] [howto] How to update to Discourse 1.0?

That’s it! You have successfully customized subject format for standard emails.

Can we get the brackets moved out of optional_cat?

I’ll have to think about that…


(Michael Downey) #3

What is the value of %{optional_cat} for posts in uncategorized topics?


(Arpit Jalan) #4

In case of uncategorized topic the %{optional_cat} is skipped altogether. So the compiled subject will be like:

[Community Title] Topic title here


(Kane York) #5

So, it’s the empty string @downey.


(Peter N Lewis) #6

I believe you chose to (rightly, sorry, my bad!) remove the %{optional_re} from the default subject, so you might want to edit the howto to reflect that change.


(Arpit Jalan) #7

I believe that %{optional_re} should be left in the howto so that users can know that this option is available.

Edited the howto to reflect that %{optional_re} is not included by default.

@techAPJ I am on Discourse 1.0.0 and this setting does not appear in the Admin / Settings / Email dashboard. Any ideas?


(Michael Downey) #9

It was introduced after the 1.0.0 release, so you’d need to be on the tests-passed or maybe beta settings now to see it.


(Domenic) #10

Oh :(. I guess I will wait for a new official release then.


(Jeff Atwood) #11

It’s pretty safe to be on the betas. This is on beta and it seems to work :wink:


(Daniel Reeves) #12

I agree the brackets should not be included. It’s clearer to just have the template include them explicitly and then you can do things like this: %topic_title [%{site_name}: %{optional_cat}]

(Though I guess that example’s ugly if there’s no category?)


(Tobias Eigen) #13

would it be possible to add eg %{optional_cat_slug} to this list of optional info to add to emails? We have long category names which are cumbersome when added to emails. The category slug would be better.

How about customizing the digest email? I wanted to show the name of one or more posts (ideally the most popular post) in the subject instead of the standard [Community Name] Digest which doesn’t look fresh/inviting.

Couldn’t find any literature on that - any help?

Unfortunately it’s not (yet) possible.

On my installation there is no trailing whitespace after %{optional_pm}, everything else works.


(Allen - Watchman Monitoring) #18

What indicates that that [brackets] are a problem?

You might try inviting an email from www.mail-tester.com to your forum, and see how it rates the message.


(Clay Heaton) #19

I’m dealing with people who won’t know what PM means… Is it possible to change that text anywhere?


(Mariel Matze) #20

Hi all,

I’m finding that the %{optional_cat} returns the topic’s original category, not current category. Is there a way to make the category in email notification subject lines update according to the topic’s current categorization?

Thanks!
