How are you handling emails for your side-projects?

For all the different domains you have, how do you manage email for those? Both receiving and sending.

I currently use Thunderbird

You can add an alias to your Gmail inbox so it sends out from your custom domain.…

Yup, I'd recommend doing what @pugson said. I have my main email address as [email protected], then I set up an alias for every domain I have... Then I can send and receive emails from [email protected] without buying another email plan.

I'm using a paid (email) hosting where I can add unlimited domains. So I setup DNS records and an SMTP account. Would not recommend it, but its flexible and cheap :) ( - they only provide their service in german unfortunately)

And remember to redirect your apps email to an email you open.
