Cerberus VS Mautic

Let’s start with one of the features that was most requested in my previous posts: Keila now has a WYSIWYG block editor! – Screenshots With the new editor comes a new base template which is based on Cerberus Hybrid and which looks great on pretty much all email clients, even tricky ones like Windows Mail.

I recommend you look into these templates: https://www.cerberusemail.com/

We have been using Cerberus since 2015, rock solid: https://github.com/TedGoas/Cerberus

Try out https://tedgoas.github.io/Cerberus/ It’s the best that I have found. Plus, you can chose between different layouts

Email templates are nothing but hacks, I've found. Here's the template I use for email, though I don't think it supports the layout you're going for. Try googling "email templates github" and see if any open source options have a solution.

Not a framework but I’ve found Ted Goad’ Cerberus templates very useful.

I customized them, extracted them into modules and created a design system which I then translated to an email CMS.

Coverage is pretty good although Outlook still glitches in some circumstances.

FWIW caniemail is unreliable and does not have full coverage.

Also with this level of complexity I’d rather start with a few tested patterns than navigate the insane labyrinth of email client inconsistencies.

Keila currently comes with one template. It’s based on the wonderful Cerberus Fluid Template and looks great on mobile! Future versions will of course let you modify the template to your heart’s content.

It might be over kill for what you need, but have you looked into Mautic? It's free and opensource.

There is Mautic which is essentially a Mailchimp alternative.

Mautic: https://www.mautic.org/ (free - opensource marketing automation platform self hosted or on AWS). Seems technical; similar to MimePost?

https://github.com/mautic/mautic is one open source entry. It's pretty robust (full disclosure, I haven't used it in 3+ years). It's a php app that runs independently of your application and has an embeddable js that makes the connection (a lot like google analytics, etc).

New Mautic 4.4.2 released today! Bug fix - Custom object plugin's import - Brienz template now stable - sticky tooltips fix - CC and BCC now valid for sending email https://github.com/mautic/mautic/releases/tag/4.4.2
