Could you explain the difference between Instantly and Mystrika? I've been reading reviews about warm-up email tools, and while many start out positive, some mention issues with deliverability and inbox rates over time. I’ve also seen comments suggesting that Mystrika’s support and deliverability may not be as strong as Instantly’s.

I'm looking to purchase a software similar to Instantly. Are you regularly updating Mystrika? When was the last update, and what new features were added? To switch from Instantly to Mystrika, I’d need a strong reason to make the change. Thanks
