Free Email Inbox Testing

Let's face it, when you're sending out an email to a lot of people, you want to make sure it looks just right. Before our Campaign Designer tools came along, that could be a pain.

Even now, if you're creating your own HTML emails, or you just want to be ultra-sure that everything is perfect, testing how your email appears in every different email client is frustratingly time consuming.

That's why we teamed up with the awesome Litmus to integrate their email testing right into Sign-Up.to. What's more, we give all our monthly plan clients free test credits every month.

Why Use Inbox Testing?

There are lots of different email clients out there. From the modern Mac Mail and Thunderbird, which tend to behave themselves, through to Outlook 2000 and the like, which, well... don't. There are ways to get around the differences but you then need to check that everything works as you expect. With Inbox Testing you see how the email *actually* appears in a real inbox, so you can be sure things look right.

How Does It Work?

Simply press the 'Start test' button in Sign-Up.to and a few minutes later we return real screenshots showing how your email appears in the top 10 email clients used by your subscribers (with images turned on, and off). If you haven't sent enough emails through us for us to be able to pick your top 10 then we test it in the average top 10 email clients across all of our clients.

No need to run different email clients and operating systems, we do everything for you.

What does it cost?

All of our monthly plan clients get 2 free tests per month, and you can buy extra tests directly from your account, starting at just £10 for 10 tests/month.
