The SendGrid PHP library validates that email addresses are being set as the From and To addresses. In this case, the complaint was that the From email address wasn't a valid email address.

$email->setFrom($this->ecomhut->getConfig('salesEmail'));

When storing email addresses, in config or in a database, you need to ensure that the string is a valid email address, including removing leading or trailing white space. To help with this, you might consider using the trim function to remove that white space

$email->setFrom(trim($this->ecomhut->getConfig('salesEmail')));

This could stop future mistakes from affecting the emails getting sent.
