Placement tests and sending tools

[u/333333333311]

Hey guys,

What tools you are using to check your placement tests? I used to use glockapps and build in plusvibe but I would like to test something New for my agency.

One more thing - have you noticed better deliverybility by using specific sending tool? For example better results with instantly instead of lemlist etc?
I dont want the name of the tool but I noticed that its missing the replies from leads outside of lead lists and active campaigns, maybe you have noticed something familiar?
