  1. Nice article but I couldn’t identify any advantages of the recommendations here against smaller SMTP services such as smtpboxes.com .A friend told me about these guys and what I understand is that they are dedicated service, while most of the examples here are using shared stack of IPs. At this moment I’m happy with the deliverability and the free support. Bit pricey for me but much cheaper than SendPulse..
