Much has been said about this already, but I just wanted to put in my vote.

I bought this only a while ago and have not explored it so much, but with whatever I have explored, this looks really amazing and the functionality seems very robust.

The dashboard is very professional, and the functionalities cover all the aspects that I need. This really seems like a very well‑thought‑out email‑sending platform, and I look forward to using it for my business.
