Why most businesses focus only on paid acquisition and dismiss email marketing and follow-up systems?

Hi Adspend Team, New here and super excited to connect with you all. I'm a copywriter and marketer based in NYC. I recently made a sample sales page for my portfolio of a fake Tony Robbins Seminar "Life Coach Mastery". Id appreciate any feedback or critiques on the copy and sales page layout. Also looking for a copywriting, YT Ad, VSL partner/ mentor to level up. Check out the sales page below: https://telesfordrobbinssalespagesample.carrd.co/

Do you have your a favorite low-cost method to test your offer's message?

512 clients and 5 years after starting my first agency -- this is almost ALWAYS true. If a prospect is a pain in the ass during the sales process, They were a pain in the ass as a client. Building an agency that is highly profitable (and you/your employees enjoy) starts with client selection You SHOULD NOT take on clients you can't serve or doubt every word you say. Just because they're willing to swipe their card, doesn't mean you should take their money.
