What do you like best about GlockApps?

The seed list testing is the main reason we keep paying for it. Before we send a big campaign we run it through GlockApps first and it shows us where it's landing across Gmail, Outlook, Yahoo, etc. The content checker is also useful. We like action steps a lot as well, because we get interesting and useful recommendations. Overall it’s a great tool that I’d recommend to any email marketer.

What do you dislike about GlockApps?

The interface feels a little outdated and some of the reports take time to interpret if you're new to it. Review collected by and hosted on G2.com.

What problems is GlockApps solving and how is that benefiting you?

Our biggest issue before was not knowing why open rates would randomly tank on certain ISPs. We'd send to our list and have no idea if we landed in spam at Yahoo or gotten throttled by Outlook until the campaign was over. GlockApps gives us visibility ahead of time, so we can notice any issues with sending domains or content before it goes out to the full list Review collected by and hosted on G2.com.
