How Our Email Spam Test Works
To provide as much actionable info as possible, our email spam test tool will asses:
● Email copy ● Images ● Links ● Headers ● The blacklist reputation of your outbound IP address ● Your SPF records

In case your email authentication isn’t set up correctly, your IP address has been blacklisted somewhere, or your copy contains some spammy words – our report will help you tighten things up, improve deliverability, and prevent future reputation issues.

There's a lot of really really awesome things. I would say the team is just very open for us. Testing things out - different segments, different copy and they turn around time is just very, very quick which I really, really appreciate and that's been consistent since day one.

Sending a few emails here and there is easy -- sending at a consistently high volume and having them delivered every time is really really hard. Senders handles that for us in spades.
