I have literally been looking for something just like this. I used to be the guy with 6 Google Apps accounts and even have a bunch grandfathered in from when they were still free.
Currently with a new domain I use Name Cheap built in forwarding for very simple stuff but it breaks once you chance your DNS. Recently I found https://forwardemail.net which is free but not a great user experience.
I think your project has tremendous value, BUT I will tell you I am initially turned off by the cost of entry. IMO you need a pricing tier for 1 domain that is either free or cheaper than Google Apps. By starting at $10/m you are asking me to pay double the cost Google Apps for a single side project. That means you are only targeting people who already run multiple side projects. However, we all know the cost of switching and reconfiguring DNS and email clients is a huge pain. I am not going to switch 2 working domains from Google to this ($10 v $10). I probably wouldn't switch 3 domains ($15 v $10 but a lot of cognitive overhead). Instead try to capture all the new side hustlers! You want the majority of people who get inspired by Product Hunt and start their first side project to sign up with you, with plans of growing to multiple projects. Make it a no-brainer by making my first domain free or ~$3/m. Then upgrade plans once the number of domains increases (1 for $3, 2 for $5, unlimited for $10). Now switching costs are on your side, not Google's. This way I pick Sidemail and keep it for life! Hope this helps, good luck!
@ethosventures Thanks for taking the time to give this feedback!
I agree with adding a starter tier, I'll go ahead and add a 1 domain for $2/month plan with unlimited inboxes for people getting started. I wanted to stay away from a free plan to make sure I'm working on something people would pay for and to prevent possible spam issues.
@jonalexr Awesome! I fully think you should get paid for the product and I know lots of plans adds complexity but this sounds like a good sweet spot. A free plan could also have very low limits like 100 emails per month. Regardless, at $2/m I am sold and will happily be your customer for at least one domain!
I canceled my account 8 months ago and they keep charging me. There is no way other than email to contact them and they dont respond. I have sent at least 10 emails to them thus far. Very very bad support!!! Do not purchase this product!!!!!!!
