I am using Sendgrid to send emails with my backend on Rails 5. I manage to send plain html files, but I can't send html.erb files. In general it works, but the embedded ruby doesn't take effect.
html.erb file:
<h1>Count <%= 2+2 %></h1>
Actual Output
Count <%= 2+2 %>
Desired Output
Count 4
The emails do deliver to my inbox.
I tried following this tutorial https://sendgrid.com/docs/Integrate/Frameworks/rubyonrails.html but that doesn't deliver emails at all. What does work is using the gem with the API key https://github.com/sendgrid/sendgrid-ruby
