Nice tools for sending/receiving emails
These tools help me when it comes to sending and receiving emails. For example, sometimes it is not immediately obvious why an email ends up in the spam folder. I used the tools after an email provider move to check if all domains (MX, SPF etc.) were moved correctly.
