Sendcastle is by far the best email marketing platform I've used. The interface is user-friendly, the analytics are detailed, and the deliverability rates are fantastic. I've seen a significant increase in open rates since switching to Sendcastle. The personalization options are also top-notch, allowing me to create highly targeted and engaging campaigns. I highly recommend Sendcastle to anyone serious about email marketing.
