I've used Instantly, SalesHandy, and several other tools that are usually considered the go-to options for cold email outreach.

Surprisingly, Mystrika has outperformed all of them for me. I've been using it for over two years, and it's been consistently reliable throughout. I even ran side-by-side tests comparing its warmup network with Instantly's, and Mystrika delivered noticeably better results. Within a month, my email deliverability improved significantly compared to what I was seeing with Instantly.

The UI still feels a bit clunky, even after the V2 update, and it doesn't have the polished look of some competitors. But when it comes to the things that actually matter - deliverability, reliability, and getting emails into inboxes - it simply gets the job done, and it does it exceptionally well.

P.S. Writing this after two years of using the product, simply because I appreciate what the founder has built and consistently delivered.
