GlockApps makes email deliverability testing much easier. I like that it shows where emails land across different mailbox providers, including inbox, spam and promo. The reports are clear and help quickly understand what may be affecting inbox placement (from authentication issues to content or reputation problems). Content analysis is my favorite, a lot of deliverability tools I used don’t have this feature. Review collected by and hosted on G2.com.

There is not much to dislike. Some reports may feel a bit detailed at first for beginners, but once you understand the dashboard the tool becomes very useful for regular email testing. Review collected by and hosted on G2.com.
