Email Blast Setup & Delivery Optimization

Job ID: 40342371

Budget: $100 – $3,000 USD

I have 400,000 email addresses of professionals in Florida. I would like to send out an email blast to them about a service I offer. I think I need to validate these addresses first, then validate catch-all addresses, utilize a 2048-bit DKIM key and use Inbox Rotation model to send. I need help with this from someone who does this for a living.
