Email copywriter, is it worth it?

Hi! I’m new to freelancing and taking up some trainings as well as attending webinars. And nagkainterest ako sa email copywriter, gusto ko sana matanong mga experts and newbies na nasa field na na ng email copywriter, binabalak ko sana magjoin sa training course for email copywriter, medyo mahal sya kaya naaalangan ako. Worth it ba for the price of 10k? Or magrely na lang sa mga free trainings kung meron? Need some advice sana kasi 10k is not something na I can afford to spend. Pero kung worth it naman, I will go for it… bahala na si batman haha
