Most of the newbie marketers are even afraid of pitchin or selling.
There's this misunderstood concept that email too often is bad.
It's one of the reason why people said that Solo Ads do not work: they spend a lot of money buyin solos, and then they not email their list.
The fact is that you have to email your list EVERY DAY.
There are very well known marketers that email their list even Six times per day.
As an example Anik Singal emails at least 2 times in a day.
Another misconcept is that you cannot pitch every day: WHY?
People will unsubscribe?
No. People unsubscribe your list if you're boring, if they don't match the target of your list, if you make fake promises.
Pitching every day is logical: IF YOU HAVE something they NEED and they subscribe your list for solving their problems... why don't you sell them what SUITS THEIR NEEDS?
I think that in a mail you have to provide value but also SELL.
It has to be clear that you are a seller, you are a Marketer, not a charity.
The final misconcept is that you havet o give your STUFF FREE: no. You don't have to always give freebies, the best of your items free. "Providing value" is abused: if you get your subscribers used to have everything free, they will never buy from you.
If you give everything free you will attract a crowd of freebie seekers who expect to have items free, of course they will never make a dime of them, and they can get angry whe you sell: "You give me all free and now...you're tryin to sell me???? you gangsta! give it free!"
So the content has to re-module for being a piece of the puzzle: to complete it they have to buy.
Alternate mails of content, relationship, and sell good items in every mail is a key for success.
