🎯 Challenge

As Przemysław Tarnowski, Green Coffee Buyer and Q Arabica Grader at Roastains, admits:

"We are a small company—a coffee roaster—and we supply coffee mainly to cafés and, more recently, to offices. We don't have the enterprise-level tools such as domain controllers or MDM. Our team consists of 10 people—sales, logistics, production, and marketing. Even for such a small team, we had problems with setting up e-mail signatures and with the functioning of e-mail clients. The generated templates did not work for everyone, employees forgot to update or even activate them, and almost everyone had a different e-mail system. This also caused many problems. GSignature improved our operations in two ways it forced us to standardize our client (Gmail or web), which eliminated technical problems

it allowed us to control e-mail signatures for all employees, and now, after the stabilization phase, we no longer think about whether the e-mail signatures are working, but how to use them now as support for marketing - dedicated e-mail signatures for B2B salespeople and separate ones for B2C service Now, our only concern when a new person joins us is finding time to take a photo for their e-mail signature. I recommend gSignature if you use Google Workspace and want functional and aesthetic e-mail signatures that work and can even sell."

💡 Solution: implementation of gSignature

In response to the difficulties with scattered email clients, manual signature setup, and lack of consistency, Roastains implemented gSignature, a platform for central management of HTML email signatures. Importantly, the system did not require advanced IT infrastructure, which was crucial for a small organization.

🔑 Key results of the implementation

Standardization of tools

The entire team switched to Gmail and the web app, eliminating technical issues caused by using different email clients.

Centralized management

The administrator can now remotely manage the entire team's signatures without having to send HTML codes and explain the process to each individual.

Automation and consistency

After initial configuration, e-mail signatures work automatically – they are always up to date, consistent, and aesthetically pleasing.

📈 Marketing in your signature? Absolutely!

After sorting out the technical issues, the company began using signatures as a tool to support sales and marketing activities. Dedicated e-mail signatures for salespeople and separate ones for the B2C department are now standard.

👤 Onboarding simplified to a minimum

For Roastains, the only challenge in onboarding new employees was... taking a photo for the e-mail signature.

🧭 Why did Roastains choose gSignature?

  • ❌ No need for integration with MDM or domain controller
  • 🌐 Browser and Gmail support
