Email blasting

I have some clients who want to do email blasting rather than gads
I need to learn it from scratch.
Can you suggest where to start and how to do it?

Start with webmail. Slowly learn about SMTP and how it works. ChatGPT or other AI will help you understand the steps.

Good Luck

Learn to build your own smtp servers if you have the time and money to invest, you'll need some basic syslinux skills, solid understainding of how SMTP, DNS, Reputation works...

If you want to start getting results quickly, use a solution that allows you to send from multiple Gmail/Hotmail accounts...and proxies
