What do you like best?
I like that the website is very easy to use and allows many different functions, including digital signatures and saving directly into your computer. I also like the options to save a template to use, which saves me a lot of time as I am always using the same forms.
What do you dislike?
I dislike that I always have to log in again every time I use the website.
What problems are you solving with the product? What benefits have you realized?
Digital signatures. Being able to edit PDF with a Mac since most PDF programs are only compatible with windows.

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.

The most common reason images in email signatures become blurry is because of the scaling settings on your mobile device. When referring to mobile devices, I am not only talking about iPhones, Androids and iPads but also smaller laptops such as Microsoft Surface Pro's and any newer laptops which have a high resolution.
An image in your email signature can become unsharp when sending even when it still looked sharp when composing. The cause of this issue lies in the way Outlook on Windows handles your image in combination with its dpi value. Outlook will rescale the image as if it was a 96 dpi image.

Steel destroyer: If the image is digital (which all images are when they are on a computer), you can't lose quality just by sending through e-mail (a digital medium). You can copy a digital file as many times as you'd like, and you won't lose quality.
