As an agency, we test a LOT of tools, software, client "back-end" systems and more. That means that, on average, I personally get about 250 e-mails per day. All of them used to land in the same inbox. Yes, even if we quickly wanted to test a tool, but didn't want to just "get another burner mail" (because sometimes things truly ARE handy, and you want to keep them), or log into a client's system (but create a designated profile).
And if you are reading this, yes, sometimes also to purchase software, but not keep it on your main account.

So when somebody recommended Paced email, having tested similar software before, I was sceptical. Usually, the limits are either too low, or the pacing on the e-mails wasn't great. But here, the digests were well-considered and structured, the e-mails were simple to create, easy to copy, the inboxes (once I found them) well laid out, and the plugin (after the update) even easier to manage.

So go ahead. Grab it. Especially if you test software, or manage an agency.
Your inbox, and your sanity, will thank you for it.
