Error: sendgrid from name not working

What's Causing This Error

This indicates that the "from" address does not correspond to a verified Sender Identity. This error prevents an email from being sent until it is fixed.

Here's How To Resolve It

Customers are asked to authenticate their sender identities in order to sustain the highest attainable sender reputations and to maintain legal sending behavior. The address your receivers will view as the sender of your emails is represented by a sender identity. You can use Domain Authentication or Single Sender Verification to authenticate one or more Sender Identities.
