Support » Plugin: SendGrid » Update breaking SMTP settings section

  • Resolved freddie79


    I have updated Sendgrid on a number of websites, and they are not sending emails anymore. When I go into the Sendgrid settings, the SMTP section is gone. I had the websites set up to use the Sendgrid username and password. This is not there any more and only seems to allow API key sending now, so is breaking all my 30 or so websites that I had set up with username/password.

  • Same here. This screwed me up pretty bad for the past few days since none of my ecommerce email notifications are being sent… did you find a way to fix? I’m just going to deactivate the plugin until they fix this..

    I’ve updated the settings to use the Sendgrid API key on about 15 sites that I maintain and it works, but there are another 20-30 sites I have built over the years which have this plugin installed and I’m concerned that it will break when the clients update the plugin (as they do their own updates). Really hope a fix is released before my clients hit the update button. The username and password fields just disappear on this updated version of the plugin.

    Thank you for providing this feedback.

    You can send emails on SMTP using an API Key.

    We needed to change this because the SendGrid API is deprecating the use of Username and Password for sending email, in favor of using API Keys. You will need to switch to using API Keys so that in the future when this functionality will be removed, you will still be able to send emails. We believe this version might be the best moment to do this.

    We have set an Update Notice when upgrading to 1.11.0, this shows up on the Upgrade Plugins page of your WordPress installation. This notice was also set on the Changelog here:

    Quote: “BREAKING CHANGE: Username & Password is no longer supported. Change your settings to use an API Key before updating.”

    In order to not experience any disruption, you can set your API Key before updating. After the update, emails should still continue to be sent using SMTP and the API Key in the new version. To make sure you have everything set up correctly, we recommend that you should check on a local installation beforehand.

    We apologize for any inconvenience this caused and thank you for your patience with us.
