Daily Digest email errors out

I keep getting this error when a daily digest email for one of my sites is sent
out:
You are getting this message because an error detected while delivered your email.
For the domain: [mydomain.com]
The log to paste when you open a support issue:
Code: 400, Message: Bad Request, Body: {“code”:“missing_parameter”,“message”:“Either of htmlContent or textContent is required”}

Anyone seeing this error?

I am using the POST SMTP plugin.

Hey @Petrushka

Welcome to the MainWP community!

I am unable to reproduce this issue on my test Dashboard.

Are you experiencing this only for Daily Digest emails, or perhaps for other emails being sent out from the Dashboard site?

Can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Info → Server (your-mainwp-dashboard.com/wp-admin/admin.php?page=ServerInformation), on the top right of the page.

Be sure to use the button like the one below; this button hides all your private information:

Pressing the button auto-copies the report to your clipboard then just paste it in a reply here.
