I decided not to reinvent the wheel and not to wander around like a blind puppy trying to figure things out. I started with a course at the Unisender school. I'm very glad I did it this way because all the assignments were related to our barbershop, and by the end of the course, we already had an automated mailing set up. Of course, I could have figured it out on my own, but the information in the courses is presented very clearly and systematically. Recently, I created a bot on Telegram by myself, regularly conduct A/B tests, and use other analytics, and I see that things are going well. I try to create creative emails, and subscribers respond positively.
