Flexible API for Seamless Cold Outreach Automation

I really like the flexibility of the GMass API as it allows me to create custom campaigns inside n8n. The ability to automate my outreach is a huge plus for my B2B business. Also, the spam solver is something that I find particularly appealing. We started using GMass from the beginning and have loved it.

Time-Saver with Outstanding Tracking Features

I use GMass for sending mass campaigns, and it saves me so much time. I like the tracking feature so much because I do marketing, and I need to track everything I do. The tracking system is the best because it helps me track clicks, see how many emails are opened, and identify mails that were not sent. Overall, it's a good tool. The initial setup was easy, taking just 5 minutes, and working with Google Sheets took a few hours to figure out.
