Hello, I need to add a dynamic code block in email bodies; from the documentation I understand that to do this task I have to code a plugin extending Code: MauticCoreBundleEventListenerCommonSubscriber in a EmailSubscriber class. So I created my HelloWorldBundle in plugin as available at https://developer.mautic.org/?php#extending-emails, but I can't figure out how to use it in email builder to insert a dynamic code. Any suggestions, hints or tips areappreciated. -Alessio ---

I’m not quite sure what your dynamic code should do, but an existing subscriber to a builder could be a good start to learn how the current functionality has been done: [https://github.com/mautic/mautic/blob/staging/app/bundles/PageBundle/EventListener/BuilderSubscriber.php](https://github.com/mautic/mautic/blob/staging/app/bundles/PageBundle/EventListener/BuilderSubscriber.php) ---

Thanks escopecz, I got it as a basic style. Anyway, I am trying to get prettier messages. It would be very nice if mails could accept a sort of templating logic (like twig), since this setup forces me to assemble and embed HTML within `EmailSubscriber` class from plugin bundle. Looking for any suggestion about; planning at the end to release my final results on github. ---

There is already a feature request for twig support: [https://github.com/mautic/mautic/issues/849](https://github.com/mautic/mautic/issues/849) ---

Hope it can be helpful this is what I roughly meant to achieve [https://github.com/afelicioni/mautic-linux](https://github.com/afelicioni/mautic-linux) ---

That is a nice plugin! The only thing I’d done differently is the plugin description. I think it’s better to use English for it. Since Mautic uses English by default. But that’s just a tiny issue. And also, it is your plugin so you can do whatever you want in it. Is that a “proof of concept” plugin or did you really need to insert the latest Linux Kernel version to an email and didn’t want to just type it? ---

Hi, as you figured it out I arranged this repository, modifying the actual plugin I written: so this is indeed a proof of concept. The original plugin inherits same files tree for bundle, but fetching data from different URL: since the original page designed to be read by final users supplies a complex tabular HTML response, I am picking via xpath string blocks I need via helper method. The original helper method returns above values, so multiple tokens replacement work is done. The original tabular data is changing asynchronously multiple times a day. ---

That’s cool. Thanks’s for sharing your plugin structure with the community! I’m sure your plugin will save a lot of time for other developers. ---
