I need an email verification expert to help me filter out invalid and inactive emails from my list.

I have an agency account with Go High Level. I have 3 subaccounts that I use for businesses that I own. The latest Sub account I set up I need to make sure that the following is locked in place: 1. All email is deliverable 2. I can send bulk SMS messages My account is A2P approved. I have a Send Grid account. I've use Lead Connector for one of my other instances in GHL. The person I'm looking for understand Go High Level CRM specifically and can get in there and make sure my email is set up properly and I send automated, bulk SMS messages.
