  • SMTP2GO is beyond incompetent
    I open a support ticket describing the situation, expecting that it is a simple oversight, but I receive a puzzling response. Their support person claims that this IP doesn't belong to them, and that it is owned by "Sand Dune Mail Ltd". I check the smtp2go.com privacy page, and it clearly lists the name of the company as "Sand Dune Mail Ltd". Source: 12 months ago
  • Why will using Google DNS work but using Cloudflare DNS not work for a website
    Hmm. Getting the IP address of a linode site instead of smtp2go.com would worry me. Source: about 1 year ago
  • Exchange OOF 2016 not working
    Our mail relay service smtp2go.com is what is causing the issue! Source: almost 2 years ago
  • Postmark acquired by marketing firm ActiveCampaign
    Https://smtp2go.com maybe? Just discovered them the other day but yet to give it a whirl. Just when I was starting to double down on Postmark, they did this. Not blaming them, but we all know this is going to go badly (as a previous Active Campaign user). - Source: Hacker News / about 2 years ago
  • Use a Gmail address with the no-cost option?
    Why would it? My response will be sent through the SMTP server at smtp2go.com which has no idea what my Gmail address is. How does my "response to meeting invite" differ from my responses to other mass emails? Source: about 2 years ago
