I have had a problem with the emails that I send for work (all to external domains) being completely blocked or sent to spam, for many different recipients in various companies, since I & # 39; I changed domain and hosting. I send 5 to 50 emails a day.
I previously had a domain name "previous.co" with BlueHost. I switched to NameCheap 3 months ago and changed my domain name to "newdomain.io" at the same time (".com" has been taken.)
I have sent emails to the same people as before, with similar messages.
Ever since I switched, I have always had problems with blocking the emails I send (they don't even appear in spam) or to spam recipients. I have never had these problems before. They started immediately when I changed.
I have verified the sending IP address and it is not on any blacklist.
I asked recipients to whitelist my email address, with mixed results. One company has indicated that it has been whitelisted, and my emails to any email address for that company simply never show up. Another company was added to the whitelist, and it worked for them.
I also changed my email client in case it helps and it makes no difference. I used MailSpring on IMAP, now I use Postbox on IMAP. My sent emails appear in the sent hosting folder. I have always sent HTML and I very often have online images and attachments of all kinds.
I received a message from Microsoft stating that I was on an Outlook 365 block list, so that is a clue. I filled out their form to request the removal of this block, I don't know if this was the case but the recipient put my list on the whitelist and we were able to communicate now for a week.
I am physically located outside of the United States, and almost all of my recipients are in the U.S., so I thought this could be a problem, but when I tracked the IP address on an email that i sent it, it just led to the Namecheap servers and there was no indication that i could see anywhere from my physical location.
I don't know what to do other than change my accommodation away from Namecheap, back to BlueHost; or could the problem still be that my domain is too new or that it is an .io domain? Any suggestion?
Sorry for the lack of specific details, some of the technical stuff is a little on my head, but I'm happy to provide details if you know what to ask.
