1&1 vs. CanSpace Solutions 2020

ke Hostinger, Godaddy and Domainracer to make a best choice.

point me in the right direction. The support staff at CanSpace are by far the most knowledgeable people when it comes to Wordpress that I have ever dealt with, and I really appreciate the extra time they take to answer my questions (that don't even have anything to do with them). I've been with them for 2 years now and they have definitely earned a positive review from me!

is means that if your agent is busy you have to rely on hope that someone else will see that your agent hasn't responded for a while and will intervene. Of course, they act like they have zero context and approach your issue like it's the first 1&1 have heard of it.
They also do this thing where the only available support option is to call them up on the telephone. Ocassionally you can do live support chat but only if your individual agent is available. Of course, the one time out of possibly 50 I have got through the agent didn't respond for 10 minutes so my attention went elsewhere and when she eventually did respond I wasn't paying attention so she closed the issue as solved (without solving it).
That is the running theme.. I have had the same issue for weeks and I just go around and around in circles trying to solve it with different people. The issue stems from where I was told I could upgrade from one account to another and they would handle the transfer. They didn't and then wanted to charge me to do the upgrade. Fortunately I had saved the chat log but even then they have still not resolved the issue and I remain paying for both services.
AVOID AVOID AVOID. They are totally useless.

my contact list says my emails are going to their spam filter - only Gmail accounts were reliably receiving messages from our domains. Of course CanSpace had no idea what I was talking about but this is the same host that repeatedly cited 'propagation time' and 'client email configuration' as the reason for almost 48 hours downtime with the transfer of these domains. In the end it turned out that their 'senior' tech discovered that our MX records had been incorrectly entered -- but no apologies offered for the lies told by their incompetent support staff. I should further add that this was only discovered after raising almost a dozen tickets because guess what? Despite claiming to offer 24/7 telephone support, their phone lines were mysteriously down when we called as they were "in the middle of moving offices" - of course. When I escalated the situation to owner Sunil and explained how messages from our domains were being blocked by half our address book since transferring them to Canspace, I was told to sign up for Amazon SES (Simple Email Service) - at an added cost - to better ensure that our messages were whitelisted. Fifteen years using the same domains with various hosts, no problem. Day one and every day after with Canspace, half the messages being sent from our domain are blocked. It was such a disruption to our business during our busiest time of year that we had to switch to using a Gmail account to ensure reliable email communication. The eventual solution? Transferring the domains the hell away from CanSpace to Namespro based in Vancouver. Total downtime? 3 hours but more importantly once again all of our emails are reaching our clients and the nightmare that is CanSpace is thankfully over. Deal with CanSpace at your own risk.
