Sending emails can be tricky, and it is by far one of the most common issue reported by our users.

No emails are being sent or received

When this issue occurs, you can safely conclude that your sending method is not working well.

It could be that your sending method is not able to send with the default from Address set in your sending method.

So you can either reconfigure your email sending method with a method of your choice or simply go for the easy solution and configure SendGrid with Wappointment. This is our number one recommendation, it will just work 99,9% of the time.

Email reminders late or never received

You are receiving confirmation emails but you are not receiving reminders? Then thatโ€™s probably because you have an issue of background scheduled tasks not being executed. Youโ€™ll need to setup a CRON task on your WordPress site.

The From Address does not match a verified Sender Identity

You are getting the following error:

POST https://api.sendgrid.com/v3/mail/send resulted in a 403 Forbidden response: {"errors":[{"message":"The from address does not match a verified Sender Identity. Mail cannot be sent until this error (truncated...)

This is an issue that will arise when trying to send with SendGrid with an unverified From Address.

In order to solve that:

  1. Check the Sender Authentication section in the SendGrid’s configuration guide
  2. And check the section Changing the sender email or From Address in the email configuration guide

No IDN encoder found

You are getting the following error:

No IDN encoder found (install the intl extension or the true/punycode package

Well this is a technical issue, here you’ll need to install the intl PHP module on your webserver, otherwise you can simply setup SendGrid as a sending method and that will work just fine.
