FAQ

Does OSEMS handle plain text emails along with HTML?​

Yes. Plain text versions are automatically generated based on HTML templates, using node-html-to-text library.

Even if sending plain text may sound optional, it's encouraged to send it along HTML in order to satisfy spam filters.

"Spam filters like to see a plain text alternative. HTML-only emails are a red flag for spam filters."
