I really appreciate Sigsync for its incredible reliability. In our 2,400-user environment, we've enjoyed a literal 100% uptime for two full years. We haven't experienced any scheduled maintenance windows affecting us, no unexpected outages, and no degraded performance, even during peak email volume or Microsoft-side issues. Everything works instantly even under high load, and the admin tools are always responsive. Signatures load instantly and banners always display, which is essential in maintaining professionalism and reliability in all client-facing emails. I find the admin dashboard always available, and the initial setup was easy and fast, with a smooth, seamless deployment. Given all this, I can say that in an enterprise where email is mission-critical, this level of reliability is indeed rare.

I mainly use Sigsync to manage all our compliance disclaimers across 18 different countries. Instead of juggling regional versions, everything lives in one central place and gets applied automatically through Azure AD groups. The centralized control is fantastic. One update and every country, team, and department is instantly aligned, which removes so much manual work and stress. It saves huge amounts of time and eliminates human error. Instead of relying on people to update their own signatures, I just adjust one line of text and know it’s correct worldwide. The setup was incredibly easy. The kind of reliability Sigsync offers is priceless when legal requirements change frequently.

I really appreciate how Sigsync manages our company-wide email signatures and runs multiple banner campaigns efficiently during busy seasons with almost 1,900 users. The support team is genuinely great, especially during Q4 when we had overlapping banners; they helped with scheduling and fixed small tracking issues fast, usually the same day. This level of support saved us from potential mess-ups during a hectic time. The setup was very easy and took less time than expected. Plus, the integration with Microsoft 365 is seamless.
