@testworking2705 I would verify that the path to sendgrid-php.php is correct. Also, I went ahead and removed the screeenshot that shows your API key in the description. I strongly recommended you refresh the key.

[testworking2705]

yes, I am already double sure with path of sendgrid-php.php .
but, am getting this the error show above.

Any reason you are using this:

require_once(APPPATH.'libraries/sendgrid-php-7.9.2/sendgrid-php.php');

opposed to an artisan install and this ?:

require 'vendor/autoload.php';

Could you develop locally, or in a virtual machine - like VirtualBox - to get the path issue resolved, then upload all the files once it's working?

If you have to hack the include and paths, you'll likely be able to see when you have access to the class like so : https://electrictoolbox.com/php-get-available-classes/
