sendgrid-python VS mailjet-apiv3-python

I use SendGrid with its dynamic templates via its Python library.

Install the SendGrid python library Finally you can install the python library. The documentation gives you some simple examples on how to send your first emails. I did not need to dig much further, those are great. This project uses the "Without Mail Helper Class" example, that I implemented in my contact_secret_santa() class method.

FWIW the reason I'm doing this is because I'm inserting some text into a message that will be sent as email. The message can either be inserted as plain text or converted to html. I'm trying to apply the HtmlContent from sendgrid.

You're talking about this, right? Where's the part that changes the protocol used? https://github.com/sendgrid/sendgrid-python/blob/main/use_cases/kitchen_sink.md

To install the sendgrid package on your machine, refer to SendGrid's GitHub installation guide or directly install via pip install sendgrid.

You can use sendgrid. They have a decent python library and they have a free plan as well. The library is pretty straight forward to setup.

If you're not bothered too much about the delivery mechanism then Mailjet might be worthwhile considering. You get about 200 emails a day for free. I use it for a personal website and it's always been spot on.
