I don’t usually write reviews, but Sinag and Roshan deserve one. We’ve worked together for years, and they’ve quietly become one of the most reliable partners in our business. What stands out most is how seriously they take their craft. Roshan runs a tight ship, and his team operates with precision, curiosity, and accountability. They adapt fast, test relentlessly, and never treat email like a “set and forget” channel. If you’re looking for an email team that actually thinks like owners, this is it.

I've been working with Sinag and Roshan for 4 years now—and counting. This is probably the most underrated email agency in the eCommerce space. Honestly, I'm hesitant to even write this review because part of me wants to gatekeep them. Roshan is a great leader and his team are exceptional operators. They never stop learning, evolving, and refining their craft. Can't recommend them enough.
