Frequently Asked Questions

Why add a plain text version?

Because it decreases the chance of your legit email being marked as being spam and thus disappearing in spam folders.

Will this mess up my HTML email?

No, the plugin does not affect the HTML message of emails.

Will the people I send email to notice?

No, 99% of all email clients will just show the HTML version of the email.

The other 1% can’t properly display HTML and will show the plain text email. Without this plugin, they would have had nothing to show.

Where can I check my SpamAssassin score?

Just great and efficient with all newsletter plugins!

A lot of WP plugins send only HTML emails. This plugin saves us from having to change to another plugin to just send plain text emails along with HTML emails. It works perfectly with WP 6.3 and Icegram Express. Thank you Danny!
