Ratings and reviews

My second letter has said sent for 4 days, was supposed to be an overnight. I even paid extra for extra pictures and it isn't showing delivered. So the next day thing isn't guaranteed. Tried to reach costumer service and can't, I get the constant loading circle to send a message or ask a question. Don't recommend spending the extra money to send a letter when you could just use regular mail for much cheaper and actually get it there!

The app is supposed to help alleviate stress of reaching your recruits, not add more! It says into your number and you can connect you go to enter the number but yet it won't let you scroll down to press send code, the whole thing is just wonky and a waste of time. extremely unhappy with the app in general. I've been trying to figure out for 4 days, and have yet to get any answers to inquiries.

So far, it's been marginal. I don't really understand the difference between plus and normal and the only difference i could see for "plus" in 12 letters vs buying 20 without it was to include 4 photos instead of just 1. I thought return postage was included with "plus" but then it asked me to pay $1.99 to include return postage 🙄.
