The EASY, AFFORDABLE Way to Securely Send and Post Online Fillable PDF Forms with e-Signature. All 100% HIPAA Compliant.


With MailHippo's© FormHippo plans, you can easily post fillable, signable PDF forms online, with HIPAA-compliant security. You can even offer patients or customers a QR code they can scan to fill & sign your forms on their own device, complete with interactive form fields. All at a fraction of the cost of other similar services.

Electronic Signature

Using the electronic signature feature, recipients can electronically apply a digital signature to any online or emailed form with the click of a button. MailHippo applies a certificate-based electronic signature with the signer’s authenticated credentials including name, email and IP address.


SignSafe Form Filler is cloud based, meaning form filling and signing is performed on our secure encrypted web-based platform with no software or apps to download. Your recipients can easily do all this from their computer or mobile device.


If posting online or via QR code isn’t for you, it’s easy to securely email your fillable, signable PDF forms to anyone--they don’t need to have MailHippo themselves. Your recipients can electronically fill & e-sign the documents, and email them securely back to you.


Enjoy peace of mind knowing that your online or emailed PDF forms are filled, signed and delivered from within MailHippo’s ultra secure HIPAA-compliant platform. This ensures all PDF forms are secured in transit AND at rest, using industry-leading 256 Bit AES encryption.

Mobile Friendly

In addition to operating effectively on both laptop and desktop computers, MailHippo's© SignSafe™ Form Filler looks and works great on any smartphones or tablets you may have as well! This way you can easily work on projects from anywhere that has an internet connection.

FormHippo© makes filling out and signing any PDF form a breeze, for both you and your clients. We’re talking patient intake forms, medical histories, payment authorizations, contracts, applications and more.

Our clients say:

My clients love MailHippo. They say it's much easier to get their EOB's and patient files than by fax.

I often need to send large files securely via email with my Telehealth practice. MailHippo is the perfect tool for this.
Dr. Hailey R.
I've tried to use some other products in the past but they required too much work to set up. With MailHippo, I was up and running in less than a few minutes, and able to keep my email address.
Dr. David B.
Doctor of Osteopathic Medicine
It’s so much easier than setting up my Microsoft Office Outlook for encryption and then having to worry if my clients can actually open and read the messages and attachments.
