So basically i have an email newsletter, where i share unbiased news by first the sharing facts of headlining stories , then both POVS ( the left and the right). So it discusses pretty serious topics and I am wondering whether it would ruin my articles integrity if i were to advertise that, I dont know if im being a pedant, but it feels wrong. What is your take on it?

for information sake: They are offering me R5000 which is about 250 dollars to post it for 5 days in every article i send out.
