We work in the B2B sector and send commercial proposals. At first, we used another service, but there were issues with delivery to corporate emails. We switched to Unisender, and the problem disappeared — emails now arrive consistently. I like that it is completely Russian software, the servers are located here, and management can rest easy regarding data protection laws. Personally, I appreciated the ready-made templates — they are really high quality, and you can create professional newsletters for partners even without being a professional designer.
