inbox

Send an email sometime on the weekend, and by the time Monday rolls around, it will be buried under a pile of other emails crowding your recipient's inbox. But what if you don't have time to send the email at just the right moment for it to be seen? If you're using Gmail, Right Inbox can do that for you. This service ($5/month or $39/year, free feature-limited demo) can also track sent emails and report when the recipient opened them, and remind you about emails that haven't received a reply so you can follow up.
