Warmbox

I won't recommend this tool, I have seen my email goes to spam after using it. Also I was few hours late to cancel my subscription and its been more than 10 days and there is no response from their team. After being contact they said they might be busy. What a shit platform

used it for 2 months , no improvements, then google started blocking the emails. i stopped using it, then tried customer support - no reply. avoid. cancelled the service. really bad after taste.

Despite the fact they claim they use all major email service providers to warm up your mailbox, they use ONLY GMAIL!!!! When I noticed that, I requested all the statistics (about ESP used) for the last few months - no one has sent me the info since the request.... Besides that, even the gmail had zero improvements, so there was no value at all.

Won't recommend anyone to use it as it would make miserable impact on your emails, along with the pathetic customer support so you will stand nowhere.
