I love that it allows me to test different variations of my emails with ease, giving me more confidence in knowing what works best for my audience. It is also easy to use once you get used to how everything looks like. Sometimes when there are multiple people working together, things can become confusing at times. However, this does not happen often so overall it's great! We have been able to see which subject lines work better than others by using A/B tests. This has helped us create much better content as well as increase our open rates.
