There’s actually no need to get terribly involved with the HTML. You can do a lot using just simple tags - on the other hand, you can build a very complex page in DreamWeaver or another HTML editor and save it as a template.
The degree to which you style the message is entirely up to you but there is a lot you can do while keeping it simple.
I do a lot of direct email marketing for my photography and send a few hundred styled emails at a time. I’ve modified my copy of Composer to merge some data from my Contacts file and to loop through the selected names to send an email blast.
I’ve also got a procedure that converts line breaks to create opening and closing paragraph tags along with some other common items. You can invent your own tags to enter into the text then have a procedure change them to proper html tags too.
I send a file that looks like this via the Composer file included with the Python Mailbox:
<body link="blue" vlink="blue" bgcolor="#f2f2f2">
<font style="font-style: normal; font-size: 16px;" face="Optima" >
<p>This is <b>not</b> an appealing photograph.

It was created on January 29, 2021 when Lake Michigan should have had a thick coat of ice stretching well beyond the shoreline towards the horizon. But in this winter, records were being set for lack of cold and snow - including a record low of 1.8% ice coverage on the Great Lakes which are normally at about 20% by the end of January.
The lakes are complex geophysical environments with many life forms dependent on them and their normal rhythms of seasonal temperatures. Lack of ice, for instance, diminishes the successful growth of diatoms that feed zooplankton that feed small fish that feed bigger fish and so on.
I've posted a slideshow, <a href="https://jamescook.biz/galleries/WestMichiganGallery.php#flr">The Lake in Winter</a>, a 14 year documentary of Lake Michigan at Oval Beach, consisting of images created during the same period of time in winter. It's interesting to see how this same view of the lake has compared over the years.
My best to you!
