Travis Cutright CTO, City of Mesa

“We were tired of DocuSign’s inconsistencies, the escalating costs, an account rep that changed every ninety days, and the lackluster customer service. The moment we switched to BlueInk, we experienced immediate benefits – a 45% cost savings, a dedicated support dream-team responding in minutes, and a more efficient business with 58% productivity improvement, 70% faster document turnaround, all in just 3 days."

Bryan Jenkins Principal Broker, AHI Properties

"BlueInk’s reasonable cost and multiple document-sharing options is the fastest and simplest way to get parent signatures, and the cost is unbeatable. Our favorite feature is the text message option, allowing us to effortlessly obtain consent for various forms. We were impressed not just by the functionality but also by the affordability. It's a fraction of the cost compared to other solutions. With BlueInk, we save time, money, and paper.”

Shauni Vaughn Director of Student Services

"Serving workers' comp statewide, signatures were a pain. We tried DocuSign and HelloSign, but they weren't efficient. BlueInk's SMS feature changed it all. Patients sign instantly, mistakes are rare. Our document processing time went from a frustrating 10 days down to less than an hour. Plus, it's a budget-friendly choice, and that's been a real game-changer for our pharmacy!”

Can I Send non-API Envelopes when I sign up for an API Plan?

API plans include a limited number of “regular” Envelopes, allowing you to send Envelopes from the Blueink Dashboard and via the API. However, if you need to regularly send Envelopes from the Dashboard and via our API, an Enterprise plan is probably the best fit for your organization. Please contact our sales team to discuss options.

Do you have an SDK for my preferred programming language?
