The support is great for any issues that I have had with my domains or emails over time! They are very quick to respond and make sure everything works as it should be. There isn't anything really bad about them at this point in time since they've been around so long but if you're looking into hosting your own mail server then there's not much benefit of using tucows anymore. Hosting our own webmail service has saved us thousands each year compared to going elsewhere. We also use their DNS servers which helps keep things simple when managing multiple websites/domains from one place (and no messing up redirects!). Mail forwarding was easy enough once we got used to how it worked - just forward an address like @mydomainnamehere@tucows.com to another mailbox where all incoming messages will go after being forwarded by default.
