 * I got a couple of email errors this morning on my WordPress site that say “ERROR:
   Status code is 100.” I clicked the Resend link on the record a minute later and
   it successfully sent the email both times, as shown here: [https://snipboard.io/sBJ5jW.jpg](https://snipboard.io/sBJ5jW.jpg)
 * Could you provide some details as to what this error code is and what may be 
   causing it?

 * Sorry for the delay, I didn’t get notified of your response here. I am using 
   SendGrid. I had two more emails fail today, this time with “ERROR: Status code
   is 0.” A couple of emails have sent successfully after receiving those errors.
