Question 1

How do I send an email after generating it with Hermes?

Accepted Answer

Hermes only generates HTML and plain-text content. You need to use an SMTP library like net/smtp or a third-party package such as gomail to send the email. The README provides optional environment variables for testing with SMTP servers.

Question 2

Can I use my own HTML templates with Hermes?

Accepted Answer

Yes, by implementing the hermes.Theme interface, you can use external templates. However, this requires additional setup and file management compared to the convenience of built-in themes.

Question 3

Hermes vs gomail for Go email sending?

Accepted Answer

Hermes is for generating themed email content, while gomail is for sending emails. They are complementary; you can use Hermes to create content and gomail to send it, but Hermes doesn't handle sending natively.

Question 4

How to change the color of buttons in Hermes emails?

Accepted Answer

Button colors are customizable by setting the Color field in the Button struct within an Action, as shown in the example with '#22BC66'. This allows branding consistency without modifying themes.

Question 5

Does Hermes support email attachments?

Accepted Answer

No, Hermes does not handle email attachments. It only generates the email body content; attachments must be managed separately by the email sending library or service you use.

Question 6

How to preview Hermes emails in a browser?

Accepted Answer

You can write the generated HTML to a local file using os.WriteFile, as demonstrated in the usage example, and open it in a web browser. This is useful for testing layouts before sending.
