I've been happily using email aliases for years now, but I've recently been having major issues with 33mail, the service I've been using, which is causing me to not receive emails. The problem is, I don't just use aliases for signups and other short-term uses; I use them permanently. I used one signing up for this site years ago, I use ones for online magazine subscriptions, online and B&M stores, PayPal, pretty much everything. So not getting emails to them is a real issue. I've looked at SG on and off for years, but never did anything, partly because 33mail was working fine and partly because I don't like the available domains (since I use aliases for real email as well as disposable, I want a "normal" sounding domain that's also easy to tell someone, so I don't have to spell it out to them every time). I've also looked on and off at buying my own domain to use, but I haven't been able to find one I like that's available, plus I'm not even sure how that all works.
In order for a service to work this way, it needs to be able to default to allow infinite messages to aliases, as it would be far too much work to manually set each one as trusted. I know there have been posts before about this, and apparently this is just not something SG is going to do, apparently due to the fact it's meant more for disposable emails that mostly get "eaten" vs a relay for all email, and I understand that, as you need to keep bandwidth in check. But I wonder if you'd be willing to do paid accounts that allow this, even if it's not actually set up. I wouldn't mind sending a check or something in order for my account to be tweaked to allow this. Another option would be to set up my own service with the source code on a service like DigitalOcean, but I have no idea how to do that, and even if I could figure it out I'd be worried about the security of it since I don't really know anything about managing that sort of thing. Which brings me to another question: how secure is this service (i.e. the server)?
As far as using my own domain, how would using SG with it differ from just using the domain on its own? Either way, I'm giving out the domain name, which opens it up to spam. With SG that's limited by only allowing emails sent to watchwords and such, and blocking aliases as needed, so I'm guessing this type of thing isn't possible with your own domain? Other than the obvious of being able to choose my domain name for my email addresses, are there any other benefits, or any additional risks, to using my own domain vs a SG one?
