Whoops, this is a bug. Subject line templating should indeed use template/text. For now, you can use the Safe escape function.

{{ .Subscriber.Name }} {{ Safe "<>" }} Hello

[rohanrajpal]

{{ Safe "<>" }}

This works! Thanks, was the above stack overflow link useful or the issue is different?

Same issue. Subject line should use plain text template processing instead of HTML.

@knadh Can I take up this issue?

[knadh]

Yes, sure. Just have to change this to template/text here:

listmonk/models/models.go

Line 439 in 75190d9

subjTpl, err := template.New(ContentTpl).Funcs(f).Parse(subj)
