Question 1

How do I use go-premailer to inline CSS in my Go email templates?

Accepted Answer

Import the premailer package, create a new premailer instance from a file or string using NewPremailerFromFile or similar methods, and call Transform for HTML or TransformText for plain text, as shown in the README example.

Question 2

go-premailer vs other CSS inlining tools like Premailer (Ruby/Python version)?

Accepted Answer

go-premailer is a Go-native library offering lightweight integration for Go projects, while Premailer in Ruby/Python has more features but requires external dependencies. Choose go-premailer for Go ecosystems; otherwise, consider language-specific alternatives.

Question 3

Does go-premailer support responsive email CSS with media queries?

Accepted Answer

No, the README does not mention support for media queries or advanced CSS. It focuses on basic inlining, so you may need to pre-process responsive styles separately or use additional tools for email client compatibility.

Question 4

How to generate a plain text email version with go-premailer?

Accepted Answer

After creating a premailer instance, call the TransformText method to extract plain text from HTML while preserving basic formatting, as demonstrated in the example code snippet in the README.

Question 5

Can go-premailer process HTML from a string instead of a file?

Accepted Answer

Yes, while the README example uses from file, the GoDoc likely provides methods like NewPremailerFromString. Check the documentation for flexible input options to handle strings directly in your code.

Question 6

Is go-premailer suitable for high-volume email sending services?

Accepted Answer

It can be efficient for moderate use, but the inlining process adds computational overhead. For high-volume scenarios, benchmark performance and consider caching processed templates to avoid bottlenecks.
