Cannot send Test Mail

Replies: 0

I’ve already set the From Email and From Name in WP Mail SMTP settings, but I still can’t send test email.
Here’s the debug log

Versions:
WordPress: 4.9.6
WordPress MS: No
PHP: 5.5.9-1ubuntu4.24
WP Mail SMTP: 1.2.5

Params:
Mailer: sendgrid
Constants: Yes
Api Key: Yes

Debug:
The from object must be provided for every email send. It is an object that requires the email parameter, but may also contain a name parameter. e.g. {“email” : “example@example.com”} or {“email” : “example@example.com”, “name” : “Example Recipient”}. – from.email; http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.from
