Junk emails everyday
Junk emails everyday, asked to be removed and still get their junk. Dont trust anyone that has to beg for work this much. Reputable companies dont go this hard for your business.

Receive spam email from them. If they were really good, they would not need to blindly send out unsolicited spam emails to millions of random people. STOP SENDING SPAM!!!

I have received spam from them at least twice a day for the last year. They do not respond to emails, phone calls or request to remove me from email list. DO NOT USE THIS FAKE COMPANY.

Everyday I get spammed by estimating company's that have common names or similar names to my contacts in my phone. Have been for more than 2 years. If you look at there addresses they will be some residential track location typically. I used one one time just to try it out. Totally worthless waste of money.

Impossible to UNSUBSCRIBE!!! Emails every other day. Fake marketing directors. Does anyone hire a cost estimator via email ads?

I came here to see if others were receiving the incessant emails, despite requesting them to stop. What I've just noticed is that CSI Estimation, LLC appears to be a legit business, but the emails come from spammers/hackers that use a variation of that name. I've received from csiestimates.com, csiestimates.net, csi-estimators.net, csicostestimates.com, etc. etc. Very annoying. Impossible to block.

Email constantly. Even if you don’t need services. No one answers phone. Annoying as hell.

This company is involved in an illegal spam operation designed to scam businesses. Run from this company.
