Draft personalized letters with Christmas Letter builder solution

It is very good for the most part; however, the pop-ups are very distracting. Also, when filling up a table with numbers, is is hard to line them up.

The UI is outstanding and very effortless. Very impressed. My only issue was with advanced features. Would have liked to know ahead of time that they were additional fee. Everything looks included and don't like being told something cost money after the fact. Second, when telling me I had to upgrade to get additional feature, it should show the difference between what I am paying verses the new amount. I was on personal plan ($6) but to get the features I needed it was ($10). It said it was $10 for advanced plan but I didn't know if that meant $10 MORE than I was already paying. I had to open site in incognito mode, look at plans to figure it out... not fun. Lastly, I was trying to send 2 separate PDFs as one doc. It took me a while to figure out where Merge was. I didn't understand why all the options under Actions were greyed out. That was very frustrating and should be improved.

I can't verify that my completed forms are actually sent to recipients. Programs keeps requesting me to have my e-mail verified but no code is ever sent to my e-mail.
