I had a little trouble finding the right form for the Post Office EDDM program. First, I got an outdated form which was corrected at the post office. When I complained to customer support, they were very helpful and I was able to access the up-to-date form.

I am a Special Education teacher, and to be able to take pdf files general education teachers are using and enter in text boxes so my students can type into the pdf is very helpful for my writing challenged students. I can also fill in answers to study guides and email or send home a paper copy for my students to study from also.

Reasonable but not fantastic Pretty decent, I'm not sure it's the best PDF software available, but it's not bad and can complete most tasks you'd ask of it. The software works for the most part well and allows the signing and creation of forms, handy for mild administrative use. Support seems limited to live chat only, which is a bit of pain if something goes wrong. It could also do with a mobile app which I don't believe there is currently.

Great Product Great Product. For years I've sought out a decent option for filling forms and signing them, as an enduser, not a provider of the document. This was very easy to do. I needed my husband's signature on it and the fact that I was able to send him a notification and had him sign from his phone REALLY made my day. AWESOME!!!

What do you like best? I like how easy it is to load my documents into pdfFiller & the multiple option for export when I'm finished. What do you dislike? Not a fan of the constant email verification especially since I've been using it for 3 years now & this is something just started in 2020 (it seems) What problems are you solving with the product? What benefits have you realized? I don't have a fax so its much easier for me to receive email documents, sign them with the signature feature in pdfFiller, and send directly to the recipient from the program. I get a notification, too, telling me my document has been downloaded. This has helped me a lot lately.
